+INET 3.6.1 (July 2017) - stable
|
|
|
+-------------------------------
|
|
|
+
|
|
|
+This release contains minor compatibility fixes. It requires OMNeT++ 5.1 or later.
|

|
|
|
+INET-3.6.0 (June 2017) - stable
|
|
|
+-------------------------------
|
|
|
+
|
|
|
+This release contains some important new features, several bug fixes, and a few
|
|
|
+minor enhancements. It requires OMNeT++ 5.1 or later.
|
|
|
+
|
|
|
+Highlights in this release:
|
|
|
+
|
|
|
+ - On Windows, INET is no longer using the auto-import feature of the linker, because
|
|
|
+ it generated more than 65536 symbols. Dependent projects crashed because of this.
|
|
|
+ All INET APIs now should be prefixed with INET_API macro. (fixes #257)
|
|
|
+
|
|
|
+ - The makefile now generates separate precompiled header for debug and release mode.
|
|
|
+ This is required to be able to quicly switch between release and debug mode in the IDE.
|
|
|
+
|
|
|
+ - The IEEE 802.11 MAC model has been extended with several new components. The
|
|
|
+ implementation is entirely based on the standard IEEE 802.11™-2012 Part 11:
|
|
|
+ Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications.
|
|
|
+
|
|
|
+ The new architecture is designed to be modular to facilitate experimenting
|
|
|
+ with new policies, features and algorithms within the MAC layer. Users can
|
|
|
+ easily replace individual components with their own implementations. Policies,
|
|
|
+ which most likely to be experimented with, are extracted into their own modules.
|
|
|
+
|
|
|
+ The new model has the following replaceable built-in policies:
|
|
|
+ - ACK policy
|
|
|
+ - RTS/CTS policy
|
|
|
+ - Originator and recipient block ACK agreement policies
|
|
|
+ - MSDU aggregation policy
|
|
|
+ - Fragmentation policy
|
|
|
+
|
|
|
+ The new model also separates the following components:
|
|
|
+ - Coordination functions
|
|
|
+ - Channel access methods
|
|
|
+ - MAC data services
|
|
|
+ - Aggregation and deaggregation
|
|
|
+ - Fragmentation and defragmentation
|
|
|
+ - Block ACK agreements and reordering
|
|
|
+ - Frame exchange sequences
|
|
|
+ - Duplicate removal
|
|
|
+ - Rate selection
|
|
|
+ - Rate control
|
|
|
+ - Protection mechanisms
|
|
|
+ - Recovery procedure
|
|
|
+ - Contention
|
|
|
+ - Frame queues
|
|
|
+ - TX/RX
|
|
|
+
|
|
|
+ There are several enhancements and new features to the previous version, the
|
|
|
+ most notable are frame exchange sequences, block acknowledgement, and MSDU
|
|
|
+ aggregation.
|
|
|
+
|
|
|
+ The new version was thoroughly tested against the old one using fingerprint
|
|
|
+ tests. The tests ensure that the new version doesn't introduce any regression.
|
|
|
+ In fact, the tests brought up a few problems in the old implementation that
|
|
|
+ were fixed in the new one.
|
|
|
+
|
|
|
+ - The power model has been extended with support for charge/current based models
|
|
|
+ as opposed to the existing energy/power based ones. A new energy management
|
|
|
+ component has also been added to separate monitoring and controlling of energy
|
|
|
+ consumers and generators from the rest of the model.
|
|
|
+
|
|
|
+ - New visualizers has been added to display packet drops and link breaks, data
|
|
|
+ contained in interface tables, routes stored in routing tables, queues filled
|
|
|
+ with packets, residual capacity of energy storages, and transport connections
|
|
|
+ between network nodes. The new visualizers are also added to the already existing
|
|
|
+ integrated ones. Note: many features that work with the 2D visualizers currently
|
|
|
+ don't work with the 3D OSG visualizers.
|
|
|
+
|
|
|
+ - Added new features for various tutorials and showcases.
|
|
|
+
|
|

|
|
+INET-3.5.0 (February 2017) - stable
|
|
|
+-----------------------------------
|
|
|
+
|
|
|
+This release contains mostly bug fixes and compatibility changes. It requires
|
|
|
+OMNeT++ 5.1. Earlier versions of OMNeT++ are *not* compatible.
|
|
|
+
|
|
|
+Highlights in this release:
|
|
|
+
|
|
|
+Build:
|
|
|
+
|
|
|
+ - The build process is now using precompiled headers. This can speed up the
|
|
|
+ build process considerably.
|
|
|
+
|
|
|
+ - Feature macros (WITH_*) that show the enablement of features are now placed
|
|
|
+ into a header file (src/inet/features.h) instead of passed on the command line.
|
|
|
+ The build process adds the WITH_OSG and WITH_OSGEARTH macro to the opp_defines.h
|
|
|
+ file when WITH_OSG/WITH_OSGEARTH is set to yes. This allows the IDE to properly
|
|
|
+ highlight/disable the appropriate code fragments.
|
|
|
+
|
|
|
+ - 64-bit build is now supported on Windows.
|
|
|
+
|
|
|
+Visualizers:
|
|
|
+
|
|
|
+ - Added a Plot figure (see InstrumentsExample).
|
|
|
+
|
|
|
+DHCP:
|
|
|
+
|
|
|
+ - DHCP fixes.
|
|
|
+
|
|
|
+ - DHCP can now activated in a Router by setting hasDHCP=true
|
|
|
+
|
|
|
+ - Added new WirelessNetWith2DHCP example.
|
|
|
+
|
|
|
+Radio:
|
|
|
+
|
|
|
+ - Added two-ray interference model (TwoRayInterference) as a pathoss model.
|
|
|
+
|
|
|
+SCTP:
|
|
|
+
|
|
|
+ - Added StreamReconfig support for SCTP (by Irene Ruengeler)
|
|
|
+
|
|
|
+GPSR:
|
|
|
+
|
|
|
+ - Allow to specify the interface name in a parameter instead of
|
|
|
+ using a hardcoded interface name.
|
|
|
+
|
|
|
+Fixes:
|
|
|
+
|
|
|
+ - Small fixes in SimpleEnergyStorage and during Antenna initialization
|
|
|
+
|
|
|
+ - Calling IPv6RoutingTable::getInterfaceByAddress(const L3Address& address) or
|
|
|
+ findGpsrOptionFromNetworkDatagram() function caused infinite recursion.
|
|
|
+
|
|
|
+ - Radio: Fixed FreeSpacePathLoss bug in the loss formula for alpha != 2 case,
|
|
|
+ reported by Benjamin Sliwa.
|
|
|
+
|
|
|
+ - SimpleVoIPServer now resolves destAddress at startTime (instead
|
|
|
+ of initialization)
|
|
|
+
|
|
|
+ - Ieee8021dRelay: fixed a null pointer crash
|
|
|
+
|
|
|
+ - StaticConcentricMobility: fixed a rounding issue
|
|
|
+
|
|
|
+ - ICMP: fixed "icmp error answer to a fragmented udp packet" problem
|
|
|
+
|
|
|
+ - ICMP: fixing bug #64: Buffer Overflow Error
|
|
|
+
|
|
|
+ - AODV: no longer causes assertion failure when RREP-ACK arrived after a timeout
|
|
|
+
|
|
|
+
|
|
|
+INET-3.4.0 (June 2016) - stable
|
|
|
+-------------------------------
|
|
|
+
|
|
|
+This INET release requires OMNeT++ 5.0. This is due to the new visualization
|
|
|
+feature which uses the Canvas and OSG APIs introduced in OMNeT++ 5.0. Most
|
|
|
+other parts of the codebase still builds with OMNeT++ 4.6.
|
|
|
+
|
|
|
+Highlights is this release:
|
|
|
+
|
|
|
+Tutorials:
|
|
|
+
|
|
|
+ - Added a Wireless Tutorial (tutorials/wireless). The tutorial consists of
|
|
|
+ several simulation models of increasing complexity, demonstrating the INET
|
|
|
+ architecture and features related to wireless communication networks. The
|
|
|
+ models are accompanied by a text which explains each step, complete with
|
|
|
+ screenshots and recorded animations.
|
|
|
+
|
|
|
+ - Added draft for a visualization tutorial.
|
|
|
+
|
|
|
+Visualizers:
|
|
|
+
|
|
|
+ - Added a new 'visualizer' folder under 'src' that contains visualizer modules.
|
|
|
+ The current visualizer modules can display the scene (optionally with osgEarth),
|
|
|
+ the network nodes (optionally with 3D models), physical objects in
|
|
|
+ the physical environment, node mobility along with movement trail, discovered
|
|
|
+ network connectivity, discovered network routes, ongoing transmissions,
|
|
|
+ ongoing receptions, propagating radio signals, and statistics.
|
|
|
+
|
|
|
+ The visualizer modules are intentionally kept separate from network protocol
|
|
|
+ models. They are responsible for displaying various aspects of the simulation
|
|
|
+ in a graphical user interface. The most common mechanism they use is looking
|
|
|
+ up other modules and/or subscribing to the signals they emit. The visualizer
|
|
|
+ modules are compatible with both Tkenv and Qtenv. In Qtenv they are able to
|
|
|
+ display on both a 2D canvas and a 3D OSG scene.
|
|
|
+
|
|
|
+Instrument figures:
|
|
|
+
|
|
|
+ - Implemented a facility that allows one to display various gauges, meters
|
|
|
+ and indicators in the network graphics that take their inputs from signals.
|
|
|
+ The "gadgets" themselves are figures that are added into the network using
|
|
|
+ @figure properties, and they are driven by signals via @statistic properties,
|
|
|
+ using a special result recorder ("figure") that sets the value in the target
|
|
|
+ figure. Figure types are: gauge, linearGauge, progressMeter, thermometer,
|
|
|
+ counter, indicatorLabel/indicatorText, and indexedImage. Their sources
|
|
|
+ are in src/inet/common/figures.
|
|
|
+
|
|
|
+ There is a demo in examples/visualization/instruments, and an additional
|
|
|
+ usage example in the Wireless Tutorial (tutorials/wireless).
|
|
|
+
|
|
|
+MAC protocols:
|
|
|
+
|
|
|
+ - Added CsmaCaMac, a simple CSMA/CA-based MAC protocol with optional
|
|
|
+ acknowledgements and a retry mechanism. With the appropriate settings,
|
|
|
+ it can approximate basic 802.11b ad-hoc mode operation. The code is
|
|
|
+ based on the original Ieee80211Mac (802.11b) from 2006.
|
|
|
+
|
|
|
+ - IdealMac: Changed out-of-band ACKs to be optional.
|
|
|
+
|
|
|
+ - LMAC, BMAC, CSMA: Fixed handling of frames with bit errors.
|
|
|
+
|
|
|
+ - WirelessNic: added optional classifier submodule
|
|
|
+
|
|
|
+ - Ieee80211Mac: Resurrected link break signal for giving up a transmission.
|
|
|
+
|
|
|
+Radio:
|
|
|
+
|
|
|
+ - The physical environment model has been extended to include a ground model.
|
|
|
+ Ground models need to implement the IGround interface that currently
|
|
|
+ contains a getElevation() method. A very simple implementation, FlatGround
|
|
|
+ is also provided.
|
|
|
+
|
|
|
+ - The TwoRayGroundReflection model has been updated to use the ground model
|
|
|
+ of the physical environment.
|
|
|
+
|
|
|
+ - Added packetReceivedFromUpper and packetSentToUpper signals.
|
|
|
+
|
|
|
+Mobility:
|
|
|
+
|
|
|
+ - Mobility models now use the initialZ parameter even if position is
|
|
|
+ initialized from the display string.
|
|
|
+
|
|
|
+ - Added VehicleMobility that simulates turning at waypoints.
|
|
|
+
|
|
|
+ - Now all mobile nodes face (i.e. set the orientation to) the direction of
|
|
|
+ movement. This affects radio reception when direction antenna is used.
|
|
|
+
|
|
|
+Physical enviromment:
|
|
|
+
|
|
|
+ - Added geographic coordinate system support.
|
|
|
+
|
|
|
+ - TracingObstacleLoss renamed to DielectricObstacleLoss.
|
|
|
+
|
|
|
+Misc:
|
|
|
+
|
|
|
+ - Added ApplicationPacket that can be used as generic application payload.
|
|
|
+ Currently it contains a sequence number.
|
|
|
+
|
|
|
+ - UDPBasicApp/UDPSink: changed to use ApplicationPacket, and record
|
|
|
+ received packet sequence numbers
|
|
|
+
|
|
|
+ - RelayUnit: Added packetReceivedFromLowerSignal and packetSentToLowerSignal signals.
|
|
|
+
|
|
|
+ - AODV: Removed AODV-RERR messages for inactive routes.
|
|
|
+
|
|
|
+ - Applications: Added throughput statistic to some applications.
|
|
|
+
|
|
|
+ - IPv4: Added sentTo/receivedFrom upper/lower signals.
|
|
|
+
|
|
|
+ - Common: Added average forest "material".
|
|
|
+
|
|
|
+ - Common: Added throughput result filter.
|
|
|
+
|
|
|
+Build:
|
|
|
+
|
|
|
+ - Added a top level 'doc' target to build all INET documentation in a single step
|
|
|
+
|
|
|
+ - Added project feature tests (tests/features)
|
|
|
+
|
|
|
+
|
|
|
+INET-3.3.0 (June 2016) - stable
|
|
|
+-------------------------------
|
|
|
+
|
|
|
+This release requires OMNeT++ 4.6 or 5.0.
|
|
|
+
|
|
|
+Build:
|
|
|
+
|
|
|
+ - Removed unnecessary -pINET from the makemake options. This caused linking
|
|
|
+ issues on Windows when 'clang' was used as a compiler. (the INET_API
|
|
|
+ macros are needed only for Visual C++)
|
|
|
+
|
|
|
+ - In makefrag, use inet_featuretool instead of scanning the compiler options
|
|
|
+ to detect the enablement of the VoIPStream and NSC features
|
|
|
+
|
|
|
+ - Fix: TCP_lwip did not compile when using the command-line make.
|
|
|
+
|
|
|
+ - Examples: 'run' script can now take parameters containing spaces (as long as
|
|
|
+ they are quoted properly)
|
|
|
+
|
|
|
+SCTP:
|
|
|
+
|
|
|
+ - Packetdrill: Added SCTP support and socket options (by Irene Ruengeler)
|
|
|
+
|
|
|
+ - SCTP: added support for the SCTP_ACCEPT command (by Irene Ruengeler)
|
|
|
+
|
|
|
+Physical layer:
|
|
|
+
|
|
|
+ - Added IdealObstacleLoss. This obstacle loss model determines power loss by
|
|
|
+ checking if there is any obstructing physical object along the straight
|
|
|
+ propagation path. The result is either total power loss if there was
|
|
|
+ such an object or no loss at all if there wasn't.
|
|
|
+
|
|
|
+MANET:
|
|
|
+
|
|
|
+ - The "MANET Routing" feature (a collection of routing protocols ported
|
|
|
+ into INET from other projects) was removed from the source tree. The
|
|
|
+ removed MANET routing algorithms are still available in the INETMANET
|
|
|
+ fork of INET (https://github.com/aarizaq/inetmanet-2.0). INET now contains
|
|
|
+ the following natively implemented MANET routing protocols: AODV, DYMO, GPSR.
|
|
|
+
|
|
|
+Fixes:
|
|
|
+
|
|
|
+ - IPv4: bug fix in IPv4 packet deserialization
|
|
|
+
|
|
|
+ - Ieee802.11: bug fix in 802.11 management code (set TID only for QoS data
|
|
|
+ frames)
|
|
|
+
|
|
|
+ - TelnetApp: bug fix (cancel pending timers correctly)
|
|
|
+
|
|
|
+ - IPv4NetworkConfigurator: bug fix: links were not properly detected by the
|
|
|
+ configurator when nodes connected to a switch were defined after the switch
|
|
|
+ in the NED file
|
|
|
+
|
|
|
+ - IPv6: double delete fixed
|
|
|
+
|
|
|
+ - IPv4RoutingTable: fix: only interfaces with the BROADCAST flag set have
|
|
|
+ local broadcast addresses
|
|
|
+
|
|
|
+ - AODV: fix: AODV stopped with an error if an ICMP error packet was received
|
|
|
+ (ICMP packets are now accepted and silently dropped)
|
|
|
+
|
|
|
+ - examples: removed obsolete fingerprints.ini files
|
|
|
+
|
|
|
+Ethernet:
|
|
|
+
|
|
|
+ - Added a separate EtherPhyFrame class. Motivation: there was no obvious way
|
|
|
+ looking at an EtherFrame to tell whether it already contains preamble+SFD
|
|
|
+ or not.
|
|
|
+
|
|
|
+ - Change: When modeling the decapsulation from PHY header (subtracting preamble
|
|
|
+ and SFD lengths), padding to minimum frame size was also undone. This is
|
|
|
+ no longer done.
|
|
|
+
|
|
|
+ - EtherIFG renamed to EtherFilledIFG
|
|
|
+
|
|
|
+ - Catch duplex-halfduplex misconfiguration and throw error
|
|
|
+
|
|
|
+ - Fix incorrect byte counting during burst
|
|
|
+
|
|
|
+ - Serializer: adapted to the introduction of EtherPhyFrame
|
|
|
+
|
|
|
+ - Serializer: fix: CRC was in wrong byte order
|
|
|
+
|
|
|
+ - Serializer: fix: length field contained incorrect value (size of frame
|
|
|
+ instead of size of payload)
|

+This release requires either OMNeT++ 4.6, or 5.0b3 or later. (Earlier test
|
|
|
+versions of OMNeT++ will not work.)
|
|
|
+
|
|
|
+IEEE 802.11 MAC model:
|
|
|
+
|
|
|
+ - After further refinement, new features, several bugfixes and validation
|
|
|
+ testing, the new MAC model was made the default one. It was also renamed
|
|
|
+ from Ieee80211NewMac to Ieee80211Mac, while the old Ieee80211Mac became
|
|
|
+ Ieee80211OldMac.
|
|
|
+
|
|
|
+ - Improvements on the new MAC model include:
|
|
|
+ * Added fragmentation support;
|
|
|
+ * Added Onoe, ARF, AARF rate control algorithms;
|
|
|
+ * Implemented early Ack timeout;
|
|
|
+
|
|
|
+ - Validation: Several validation tests were run against the ns-3 Wifi model.
|
|
|
+ In the tested configurations, it was ensured that new Mac model behaves
|
|
|
+ *exactly* as the ns-3 model (that is, timestamped packet logs match exactly).
|
|
|
+ Discrepancies were resolved with bugfixes in our code, in the ns-3 code,
|
|
|
+ or both. Bugs found in ns-3 were reported in the ns-3 bugtracker.
|
|
|
+ See tests/misc/ns3.
|
|
|
+
|
|
|
+Physical layer:
|
|
|
+
|
|
|
+ - Added support for the simulation of separate signal parts in the Radio.
|
|
|
+ The preamble, header and data parts can be optionally simulated
|
|
|
+ separately. This results in a more accurate simulation, because a
|
|
|
+ reception may be aborted before the data part is received.
|
|
|
+
|
|
|
+ - Added separate preambleDuration parameters to each radio transmitter for more
|
|
|
+ flexible configuration.
|
|
|
+
|
|
|
+ - Added Ieee80211IdealRadio, an ideal channel model (aka unit disc radio)
|
|
|
+ suitable for use with Ieee80211Mac.
|
|
|
+
|
|
|
+Fixes:
|
|
|
+
|
|
|
+ - Fixed PER computation in NetworkConfiguratorBase.
|
|
|
+
|
|
|
+ - Fixed missing byte length in AODV and added control packet length configuration.
|
|
|
+
|
|
|
+ - RTT initialization was fixed in TCP (Vegas, Westwood) because the original
|
|
|
+ value caused "out of range" error with the overflow check introduced in
|
|
|
+ OMNeT++ 5.0b3.
|
|
|
+
|
|
|
+ - BPDU packet length was incorrectly set sometimes in the 802.1d model.
|
|
|
+
|
|
|
+ - Fixed incorrect sign of lastSpeed in some mobility models.
|
|
|
+
|
|
|
+ - The VoIPStream app has been updated to work with the ffmpeg version
|
|
|
+ distributed in Ubuntu 15.10
|
|
|
+
|
|
|
+ - Added some INET_API macros to compile properly on Windows.
|
|
|
+
|
|
|
+ - QoSClassifier example no longer needs the 802.11 project feature.
|
|

|
+INET-3.1.1 (October 2015) - Stable
|
|
|
+----------------------------------
|
|
|
+
|
|
|
+Changes:
|
|
|
+
|
|
|
+ - Fixed build problem on Windows
|
|
|
+
|
|
|
+
|
|
|
+INET-3.1.0 (October 2015) - Stable
|
|
|
+----------------------------------
|
|
|
+
|
|
|
+This release requires OMNeT++ 4.6 or later. In addition to several bug fixes,
|
|
|
+it features the following additions compared to INET-3.0:
|
|
|
+
|
|
|
+1. A modular and extensible new 802.11 MAC model.
|
|
|
+
|
|
|
+ It replaces the existing monolithic 802.11 MAC model that has become
|
|
|
+ increasingly difficult to maintain and extend over the years. The new MAC
|
|
|
+ has a modular design, where components can be swapped in and out. Concepts
|
|
|
+ such as contention-based channel access, frame exchange sequences, EDCA
|
|
|
+ queues, aggregation, fragmentation, duplicate detection, block acknow-
|
|
|
+ ledgement, frame rate selection, automatic rate selection, etc would
|
|
|
+ be expressed as self-contained C++ classes that implement abstract
|
|
|
+ interfaces and (may) have multiple implementations.
|
|
|
+
|
|
|
+ This kind of modular design also favours the open-source development model,
|
|
|
+ because abstract interfaces give contributors better cues on where to start
|
|
|
+ implementing a new feature, and new classes can be more readily accepted
|
|
|
+ into the codebase because changes to existing code (and thus the risk of
|
|
|
+ introducing new bugs) can be minimized.
|
|
|
+
|
|
|
+ In this initial form, it has roughly the same set of 802.11 features as the
|
|
|
+ old Ieee80211Mac module: basic DCF and EDCA, with the channel access and
|
|
|
+ some more parameters being configurable.
|
|
|
+
|
|
|
+ For now, the old Ieee80211Mac is still the default one for simulations.
|
|
|
+ To switch to using the new one, add the following line to your omnetpp.ini:
|
|
|
+
|
|
|
+ **.macType = "Ieee80211CompatibleNewMac"
|
|
|
+
|
|
|
+ Ieee80211CompatibleNewMac is a wrapper around Ieee80211NewMac to make its
|
|
|
+ parameterization similar to the old MAC.
|
|
|
+
|
|
|
+ Note that the new MAC is a compound module. You can double-click on the mac
|
|
|
+ submodule (in Tkenv) and expore its internals.
|
|
|
+
|
|
|
+ See the ChangeLog in src/inet/linklayer/ieee80211/newmac/ for more
|
|
|
+ information. The same folder also contains a presentation about the
|
|
|
+ architecture of the new MAC, as it was presented at the 2nd OMNeT++
|
|
|
+ Community Summit in September 2015 (see http://summit.omnetpp.org).
|
|
|
+
|
|
|
+2. Packetdrill. This is a port of Google's Packetdrill testing tool into
|
|
|
+ the INET Framework.
|
|
|
+
|
|
|
+ Google released the script-based Packetdrill tool in 2013. It allows one
|
|
|
+ to test transport protocols like UDP and TCP on Linux and BSD-based
|
|
|
+ operating systems. Scripts define test cases that inject packets to the
|
|
|
+ protocol implementation under test, perform operations using the API
|
|
|
+ controlling the transport protocol, and verify the sending of packets, all
|
|
|
+ at specified times. The ported version provides a simple and powerful
|
|
|
+ method of testing transport protocols implemented in INET.
|
|
|
+
|
|
|
+ Packetdrill has been contributed by Irene Rungeler and Michael Tuexen at
|
|
|
+ FH Muenster. Packetdrill has been presented at the 2nd OMNeT++ Community
|
|
|
+ Summit in September 2015; find the paper and presentation slides
|
|
|
+ at http://summit.omnetpp.org.
|
|
|
+
|
|
|
+3. Manet protocols in inet.routing.extras package are now disabled by default.
|
|
|
+ You can still enable the MANET feature manually or you can use INETMANET
|
|
|
+ (a fork of INET) which contains a more up to date codebase for these protocols.
|
|
|
+
|
|
|
+4. Changes and bug fixes in the (old) 802.11 MAC:
|
|
|
+
|
|
|
+ - The default lot time was not always correctly chosen for the configured
|
|
|
+ mode (modulation and coding scheme).
|
|
|
+
|
|
|
+ - Change maxQueueSize's meaning to per AC queue. Before, maxQueueSize
|
|
|
+ referred to the total of the AC queue lengths, which could cause starvation
|
|
|
+ of higher priority queues (see ChangeLog for more info.)
|
|
|
+
|
|
|
+ - Removed external queue support, that is, the mgmt submodule in the Nic
|
|
|
+ no longer serves as a passive queue for the MAC.
|
|
|
+
|
|
|
+
|
|
|
+INET-3.0.0 (June 2015) - Stable
|
|
|
+-------------------------------
|
|
|
+
|
|
|
+This release requires OMNeT++ 4.6 or later. There are numerous breaking changes
|
|
|
+since the latest stable version (2.6). Please read this file carefully and
|
|
|
+see the ChangeLog files in the source for more details.
|
|
|
+
|
|
|
+Nodes:
|
|
|
+ - Modules that represent a "node" at network level should be tagged with
|
|
|
+ @networkNode property instead of @node. (The @node property name was
|
|
|
+ too generic.) The INode module interface was renamed to INetworkNode, too.
|
|
|
+
|
|
|
+Applications:
|
|
|
+ - The functionality of PingTestApp was merged into PingApp and PingTestApp
|
|
|
+ was removed.
|
|
|
+
|
|
|
+Network Layer:
|
|
|
+ - Refactored IPv4/IPv6 options to use TLVOptions structure.
|
|
|
+
|
|
|
+
|
|
|
+INET-2.99.1 (May 2015) - Development
|
|
|
+------------------------------------
|
|
|
+
|
|
|
+This release is the last development snapshot of the upcoming INET-3.0 version.
|
|
|
+
|
|
|
+The highlights of this release are:
|
|
|
+
|
|
|
+1. Includes a new packet/bit/symbol level physical layer model for the 802.11
|
|
|
+ OFDM PHY according to the IEEE 802.11-2012 standard, and a hypothetical
|
|
|
+ generic packet/bit/symbol level APSK physical layer model for further
|
|
|
+ experimentation. The new implementations include forward error correction
|
|
|
+ encoding/decoding, scrambling/descrambling, interleaving/deinterleaving, and
|
|
|
+ modulation/demodulation.
|
|
|
+
|
|
|
+2. Contains fixes for more than 300 defects found by Coverity, an online C++
|
|
|
+ static code analysis tool. The reported Defect Density is decreased to
|
|
|
+ 0.5/kLoC which is considered a result. You can find the detailed results at
|
|
|
+ https://scan.coverity.com/projects/3472
|
|
|
+
|
|
|
+3. Contains several other memory leak and memory management fixes reported by
|
|
|
+ valgrind memcheck.
|
|
|
+
|
|
|
+4. Modernizes C++ source code using new C++11 features such as nullptr, auto
|
|
|
+ types, range loop, override, etc.
|
|
|
+
|
|
|
+Read on for further details.
|
|
|
+
|
|
|
+All components:
|
|
|
+ - Replaced all variants of findModuleWherever calls with module parameters,
|
|
|
+ because their behavior is non-predictable and less composable.
|
|
|
+ - Replaced most getParentModule calls with module parameters to make modules
|
|
|
+ less dependent on their context, and thus more reusable.
|
|
|
+ - Replaced UnimplementedModule and all related *_None modules with calls to
|
|
|
+ firstAvailableOrEmpty NED function, and changed affected submodules to be
|
|
|
+ present conditionally.
|
|
|
+ - Moved interface classes under contract subdirectories. Moved base classes
|
|
|
+ under base subdirectories.
|
|
|
+ - Introduced a new script called 'inet_featuretool' in the root folder of the
|
|
|
+ project that allows listing/enabling/disabling specific features from the
|
|
|
+ command line. Use 'inet_featuretool -h' for further info.
|
|
|
+ The 'make makefiles' command now uses this tool to extract the required
|
|
|
+ command line options to generate the makefile. This means that after
|
|
|
+ enabling/disabling a feature you always have to invoke 'make makefiles'
|
|
|
+ to regenerate the makefile based on the new feature enablement state.
|
|
|
+
|
|
|
+Nodes:
|
|
|
+ - All "node type" modules implement the INode module interface so it is now
|
|
|
+ possible to create networks (using the <"actualNodeType"> like INode construct)
|
|
|
+ where the actual node type can be configured from an ini file.
|
|
|
+
|
|
|
+Emulation:
|
|
|
+ - Network Emulation feature no longer depends on OMNeT++ to detect the presence
|
|
|
+ of PCAP. Instead the feature can be turned on/off by the user.
|
|
|
+
|
|
|
+Common:
|
|
|
+ - Added create-module and delete-module commands to ScenarioManager.
|
|
|
+ - New macros in INETDefs.h to test INET version: INET_VERSION (format: 0xAABB
|
|
|
+ where AA is the major while BB is the minor version in hex) and
|
|
|
+ INET_PATCH_LEVEL (format: 0xCC is the patch level in hex).
|
|
|
+ - On Linux, specifying --valgrind as the first argument for the opp_run script
|
|
|
+ (or a run script in the examples folder) will start the simulation using the
|
|
|
+ 'valgrind' memory profiler.
|
|
|
+ - Added a reusable HeatMapFigure and a GaugeFigure.
|
|
|
+ - Added a reusable DelayedInitializer to support static member initialization
|
|
|
+ without having to worry about the initialization order.
|
|
|
+ - Renamed ByteArrayMessage to RawPacket.
|
|
|
+
|
|
|
+Environment:
|
|
|
+ - Added isometric view angles to physical environment visualization.
|
|
|
+ - Added class and module interfaces to physical environment.
|
|
|
+
|
|
|
+Mobility:
|
|
|
+ - Added a new StaticConcentricMobility similar to StaticGridMobility that places
|
|
|
+ nodes on concentric circles.
|
|
|
+ - Removed TracCI and TraCIScenarioManager because these modules are maintained
|
|
|
+ in the Veins framework.
|
|
|
+
|
|
|
+Serializer:
|
|
|
+ - Refactored packet serializer classes to use a safe buffer class to read and
|
|
|
+ write binary data. This allows parsing incorrect binary representations without
|
|
|
+ runtime errors required by bit precise physical layer models.
|
|
|
+ - Refactored recursion in serializers to be extensible with new packet formats
|
|
|
+ without modifying existing code.
|
|
|
+ - Fixed a number of packet length bugs and inconsistencies between serialized
|
|
|
+ and non-serialized forms.
|
|
|
+
|
|
|
+Application:
|
|
|
+ - Merged NetPerfMeter application from the master branch added by Thomas Dreibholz.
|
|
|
+
|
|
|
+PCAP:
|
|
|
+ - Allow flushing the pcapFile after each write to ensure that all packets are
|
|
|
+ captured in case of a crash.
|
|
|
+
|
|
|
+Transport Layer:
|
|
|
+ - Added ITransportPacket interface to TCPSegment, UDPPacket, and SCTPMessage.
|
|
|
+ It allows generic handling of transport packets.
|
|
|
+
|
|
|
+SCTP:
|
|
|
+ - Added fragPoint parameter to limit the size of fragments.
|
|
|
+ - After the handshake only send heartbeats on unconfirmed paths.
|
|
|
+ - Fixed close command handling, i.e. stop reading when the command is sent.
|
|
|
+ - Handle SACK and NR_SACK separately and use getByteLength instead of getBitLength.
|
|
|
+ - Fixed several bugs.
|
|
|
+
|
|
|
+TCP:
|
|
|
+ - Refactored and cleaned up TCP header options.
|
|
|
+ - Fixed scaling window bug (Martin Becke).
|
|
|
+
|
|
|
+Network Layer:
|
|
|
+ - Factored out the network topology extraction algorithm from IPv4NetworkConfigurator
|
|
|
+ into a base class.
|
|
|
+ - Added support to IPv4NetworkConfigurator for computing wireless shortest path
|
|
|
+ based on a simple packet error rate estimation.
|
|
|
+ - Added netmaskRoutes parameter to IPv4RoutingTable to control whether netmask
|
|
|
+ routes are maintained or not.
|
|
|
+ - Added useAdminDist parameter to IPv4RoutingTable to enable/disable the use
|
|
|
+ of Cisco specific routing entry extension (disabled by default).
|
|
|
+ - Added IGMPv3 implementation (the orinal code came from the ANSA project).
|
|
|
+ It has been almost fully rewritten and extended by Tamas Borbely.
|
|
|
+
|
|
|
+Routing:
|
|
|
+ - Added PIM-DM and PIM-SM implementation. The original codebase (from the ANSA project
|
|
|
+ http://nes.fit.vutbr.cz/ansa) has been extensively reviewed, refactored and
|
|
|
+ extended by Tamas Borbely.
|
|
|
+
|
|
|
+Configurator:
|
|
|
+ - Refactored supported metrics (hopCount, delay, dataRate, errorRate) and related
|
|
|
+ parameters in IPv4NetworkConfigurator.
|
|
|
+ - Added autoroute XML configuration element to IPv4NetworkConfigurator. It provides
|
|
|
+ parameters for the automatic route discovery. The autoroute element determines
|
|
|
+ the set of routing tables that will be modified, the set of destinations for
|
|
|
+ which the shortest path will be computed, the used metric and the cost for nodes
|
|
|
+ and links.
|
|
|
+
|
|
|
+Link layer:
|
|
|
+ - Added TUN/TAP virtual network interfaces thanks to Irene Ruengeler. This kind
|
|
|
+ of interfaces send/receive packets to/from TUN applications.
|
|
|
+ - Updated the 802.11 MAC implementation to use the new 802.11 mode descriptors.
|
|
|
+ - Replaced the old 802.11 operational mode and modulation descriptor classes.
|
|
|
+ This change modifies the fingerprint of a few simulations, because the header
|
|
|
+ length was computed incorrectly.
|
|
|
+ - Changed the 802.11 MAC to use asynchronous commands to set the radio mode.
|
|
|
+ - Updated the 802.11 MAC state machine diagram (graphviz) to reflect the current
|
|
|
+ state of the implementation.
|
|
|
+ - Added safety guard to the 802.11 MAC against recursively calling handleWithFSM.
|
|
|
+ - Fixed packet order in transmissionQueue.
|
|
|
+ - Renamed getNetworkInterfaceModule to getInterfaceModule in InterfaceEntry.
|
|
|
+ - Improved response time on external interfaces. On Linux cSocketScheduler is now
|
|
|
+ using immediate mode to reduce the CPU usage while still maintaining a fast
|
|
|
+ sub millisec response time (Artur Scussel). On Windows and MAC OS X the polling
|
|
|
+ interval was reduced to improve the response time.
|
|
|
+ - Added support for sending NF_LINK_BREAK signal from BMAC and CSMA. This is
|
|
|
+ required for certain routing protocols (i.e. AODV) to function properly.
|
|
|
+ - Extended Ethernet macs accept raw packet
|
|
|
+
|
|
|
+Physical layer:
|
|
|
+ - Extended the physical layer contract interfaces for layered implementations.
|
|
|
+ - Added signal representations for packet domain, bit domain, symbol domain,
|
|
|
+ sample domain and analog domain, and also added contracts for the processing
|
|
|
+ components in all of these domains.
|
|
|
+ - Added a detailed 802.11 OFDM physical layer implementation that supports
|
|
|
+ packet-level, bit-level, and symbol-level simulations in compliant, and also
|
|
|
+ in freely configurable non-compliant operational modes.
|
|
|
+ - Replaced the old 802.11 operational mode and modulation descriptor classes.
|
|
|
+ The new classes are more detailed and more complete implementations. They
|
|
|
+ supports both the flat and the layered physical layer models and provide PHY
|
|
|
+ characteristics. The implemented 802.11 modes are: DSSS, HR-DSSS, FHSS, IR,
|
|
|
+ OFDM, ERP-OFDM.
|
|
|
+ - Added IEEE 802.11 High Throughput mode descriptor. This mode is defined in
|
|
|
+ Clause 20. High Throughput (HT) PHY specification in the IEEE 802.11-2012
|
|
|
+ specification. The new HT mode makes available the Wifi n modes in the
|
|
|
+ Ieee80211ModeSet.
|
|
|
+ - Added a simple hypothetical APSK physical layer implementation that supports
|
|
|
+ packet-level, bit-level, and symbol-level simulations with widely configurable
|
|
|
+ bit-domain and symbol-domain parameters.
|
|
|
+ - Consistently moved packet level and bit level implementations into separate
|
|
|
+ subdirectories throughout the physical layer.
|
|
|
+ - Added a generic convolutional encoder/decoder, a generic additive
|
|
|
+ scrambler/descrambler, and a 802.11 specific interleaver/deinterleaver.
|
|
|
+ - Added a separate modulations folder that contains descriptor classes for
|
|
|
+ various keying techniques such as BPSK, QPSK, QAM16, QAM64, QAM256, MQAM,
|
|
|
+ DBPSK, DQPSK, MASK, MFSK, MPSK, DSSS-OQPSK-16, etc.
|
|
|
+ - Reimplemented the computation of BER and SER based on the SNIR for the QAM-like
|
|
|
+ modulations according to wikipedia.
|
|
|
+ - Added a special IntervalTree cache for efficiently computing arrival intervals
|
|
|
+ for transmissions. This change drastically increases the physical layer
|
|
|
+ performance for large networks with lots of ongoing transmissions.
|
|
|
+ - Refactored the radio medium model to support the optional representation of
|
|
|
+ PHY frames for the layered physical layer models.
|
|
|
+ - Refactored the medium analog model to simultaneously support the new layered
|
|
|
+ and the already existing flat radio signal models.
|
|
|
+ - Refactored the existing 802.11 statistical error models to use the new
|
|
|
+ operation mode descriptors.
|
|
|
+ - Extracted the BER table based 802.11 statistical error model into a separate
|
|
|
+ class. This change modifies the fingerprint of simulations that use this
|
|
|
+ error model.
|
|
|
+ - Added a new detailed 802.11 error model that computes erroneous packet
|
|
|
+ domain, bit domain or symbol domain signal representations.
|
|
|
+ - Added 802.11 OFDM PHY frame serializer.
|
|
|
+ - Extracted separate CommunicationCache classes from RadioMedium.
|
|
|
+ - Extracted separate CommunicationLog class from RadioMedium.
|
|
|
+ - Extracted a separate MediumLimitCache module from RadioMedium.
|
|
|
+ - Extracted a separate MediumVisualizer module from RadioMedium.
|
|
|
+ - Added optional recent communication heat map to MediumVisualizer.
|
|
|
+ - Renamed radio control info classes to TransmissionRequest and ReceptionIndication.
|

+INET-2.99.0 (November 2014) - Development
|
|
|
+-----------------------------------------
|
|
|
+
|
|
|
+This release is a snapshot of the development that has begun in early 2013, and
|
|
|
+will culminate in the release of INET-3.0. The code is work in progress, which
|
|
|
+means all details may still change until 3.0 is reached.
|
|
|
+
|
|
|
+This release requires OMNeT++ 4.6 or later.
|
|
|
+
|
|
|
+The highlights of this release are:
|
|
|
+
|
|
|
+ 1. Network layer refactoring that allows higher layer protocols (including
|
|
|
+ routing protocols) to be written in a network protocol agnostic manner.
|
|
|
+
|
|
|
+ 2. A new physical layer model that builds upon the INET and MiXiM physical
|
|
|
+ layers, and brings them to new heights. Design goals were extreme modularity,
|
|
|
+ extensibility, the ability to support (and easily switch between) various
|
|
|
+ levels of detail, and the ability to add support for exploiting various
|
|
|
+ pieces of parallel hardware.
|
|
|
+
|
|
|
+ 3. Extensive refactoring aimed at improving code quality. It includes
|
|
|
+ directory restructuring, code formatting, refactoring of init stages and
|
|
|
+ publish-subscribe communication, and more.
|
|
|
+

|
|

+ - Ported MAC protocols from MiXiM: CSMA, BMACLayer, and LMacLayer.
|
|
|
+
|
|
|
+Network layer:
|
|
|
+
|
|
|
+ - IPv4/IPv6: dynamic registration of upper layer protocols.
|
|
|
+ TCP, UDP, SCTP, RSVP, OSPF, MANET are all merged into transport gates.
|
|
|
+ Network user modules must register their protocol number by sending
|
|
|
+ an IPRegisterProtocolCommand from initialize().
|
|
|
+ Introduced an IPSocket class that wraps the registration process.
|
|
|
+
|
|
|
+ - Refactoring: routing tables and routes now implement a common IRoutingTable
|
|
|
+ and IRoute C++ interface (details below)
|
|
|
+
|
|
|
+ Motivation: allow uniform access to the IPv4, IPv6 and possibly other routing tables;
|
|
|
+ e.g. some wireless networks may use MAC address as network address. Also, in
|
|
|
+ simulation it sometimes makes sense to work with simple abstract addresses like
|
|
|
+ module names, indices or IDs.
|
|
|
+
|
|
|
+ Being able to uniformly access routing tables containing different types of
|
|
|
+ addresses makes it possible to implement routing protocols in generic way.
|
|
|
+ I.e. the same DYMO module can work with IPv4, IPv6, MAC and other addresses
|
|
|
+ without change and recompiling.
|
|
|
+
|
|
|
+ Ingredients of this patch:
|
|
|
+ - generic L3Address class that can hold all kinds of addresses (=union)
|
|
|
+ - interfaces for generic access: IRoutingTable, IRoute, INetworkDatagram, etc.
|
|
|
+ - Ping refactoring (use generic addressing instead of hardcoded IPv4, IPv6)
|
|
|
+ - merged routing table change notification constants for IPv4 and IPv6
|
|
|
+
|
|
|
+ - NetworkLayer was renamed to IPv4NetworkLayer and moved into src/networklayer/ipv4;
|
|
|
+ same for IPv6 (NetworkLayer6 -> IPv6NetworkLayer).
|
|
|
+
|
|
|
+ - IPvXAddress ha been extended and renamed to L3Address. Similarly,
|
|
|
+ IPvXAddressResolver became L3AddressResolver. In addition to IPv4 and IPv6
|
|
|
+ addresses, L3Address also allows using other kinds of addresses and identifiers
|
|
|
+ (e.g. MACAddress, module IDs, module paths) for network-layer addressing.
|
|
|
+
|
|
|
+ - Added GenericNetworkProtocol, which is a simplified network protocol with
|
|
|
+ table-based forwarding. It uses L3Address, so it is agnostic to the network-layer
|
|
|
+ address type.
|
|
|
+
|
|
|
+ - Added MultiNetworkLayer, which is a wrapper for multiple network layers; in
|
|
|
+ practice it can be used for simulating IPv4/IPv6 dual-stack hosts.
|
|
|
+
|
|
|
+ - Ported network protocols from MiXiM: Flood, ProbabilisticBroadcast, and WiseRoute.
|
|
|
+
|
|
|
+C++ source cleanup:
|
|
|
+
|
|
|
+ - Changed include directives to specify the full path of the header file. This
|
|
|
+ resolves ambiguities caused by different projects having similar header files,
|
|
|
+ and by case-insensitive file systems (Windows).
|
|
|
+
|
|
|
+ - Changed header guards to use a uniform syntax.
|
|
|
+
|
|
|
+ - Applied code formatting (whitespace, braces, etc.) Formatter script (based on
|
|
|
+ uncrustify) is under _scripts/reformat, for future formatting needs.
|
|
|
+
|
|
|
+ - Introduced C++ namespaces: inet, inet::utils, inet::ospf, inet::bgp, inet::sctp, etc.
|
|
|
+
|
|
|
+ - Init stages have been refactored: initialization is now done bottom-up,
|
|
|
+ by layers, and hardcoded init stage numbers have been replaced by symbolic
|
|
|
+ constants.
|
|
|
+
|
|
|
+ - Removed NotificationBoard and INotifiable: all modules now use OMNeT++ signals
|
|
|
+ for publish/subscribe communication.
|
|
|
+
|
|
|
+ - Improved logging: log messages have been classified by importance, and logging
|
|
|
+ to EV has been replaced by EV_ERROR, EV_WARN, EV (for EV_INFO), EV_DETAIL,
|
|
|
+ EV_DEBUG and EV_TRACE accordingly. Proper support for these log categories
|
|
|
+ will be available from OMNeT++ 5.0, for 4.x they are simply mapped to EV.
|
|
|
+
|
|
|
+ - Several modules have been adapted to the coding conventions, e.g. the RTP models.
|
|
|
+
|
|
|
+Directory reorganization:
|
|
|
+
|
|
|
+ - Moved src/ under src/inet/ to avoid header conflicts with 3rd party software.
|
|
|
+
|
|
|
+ - base/ and util/ have been consolidated into common/ and its several subdirectories
|
|
|
+ (e.g. common/misc/, common/geometry/, common/queue/, common/lifecycle/)
|
|
|
+
|
|
|
+ - queue/ has become common/queue/.
|
|
|
+
|
|
|
+ - Routing protocols have been moved into the new routing/ toplevel directory
|
|
|
+ from networklayer/routing/, networklayer/bgpv4 and networklayer/ospfv2/.
|
|
|
+
|
|
|
+ - Protocols in networklayer/manetrouting/ have been moved into routing/extras/.
|
|
|
+
|
|
|
+ - transport/ has been renamed to transportlayer/.
|
|
|
+
|
|
|
+ - battery/ has been replaced by power/, intended to hold models for power management
|
|
|
+ related components.
|
|
|
+
|
|
|
+ - The physicallayer/ toplevel directory has been created to hold the new physical
|
|
|
+ layer model.
|
|
|
+
|
|
|
+ - The environment/ toplevel directory has been created for models that represent
|
|
|
+ the global physical environment.
|
|
|
+
|
|
|
+ - world/ no longer exists, its contents has been distributed to other directories.
|
|
|
+
|
|
|
+ - status/ lives on as common/lifecycle/.
|
|
|
+
|
|
|
+ - networklayer/autorouting/ has become networklayer/configurator/.
|
|
|
+
|
|
|
+ - applications/httptools/ has been split up to several subdirectories: browser/,
|
|
|
+ server/, configurator/, common/.

+INET-2.3.0 (March 17, 2014)
|
|
|
+---------------------------
|
|
|
+
|
|
|
+This release contains several new protocols, and a lot of changes that were
|
|
|
+backported from the current integration branch (destined to be INET 3.0).
|
|
|
+This release requires OMNeT++ 4.3.
|
|
|
+
|
|
|
+Application startTime/stopTime fixes:
|
|
|
+
|
|
|
+ - apps start sending at startTime, and send their last packet
|
|
|
+ before stopTime
|
|
|
+ - negative stopTime means sending forever
|
|
|
+ - if startTime and stopTime are the same, the app sends a single
|
|
|
+ packet only (except TCP apps)
|
|
|
+
|
|
|
+DHCPServer and Client:
|
|
|
+
|
|
|
+ - The whole implementation has been reviewed to bring it closer to
|
|
|
+ the standards defined in RFC 2131 and 2132.
|
|
|
+
|
|
|
+ - Major changes were made both in client's and server's state machines.
|
|
|
+ It is now extended with new states (INIT-REBOOT, REBOOTING) and
|
|
|
+ with new message types (DHCPNAK, DHCPDECLINE). The new states allow
|
|
|
+ the user to model scenarios with lifecycle events.
|
|
|
+
|
|
|
+ - The server's performance model has been removed.
|
|
|
+
|
|
|
+ - The internal representation of the DHCP options were moved to the
|
|
|
+ DHCPOptions INET message definition file.
|
|
|
+
|
|
|
+ - Limitation: The client module currently does not support multiple
|
|
|
+ DHCP servers and BOOTP relay agents.
|
|
|
+

|
|
|
+ - added support for using SCTP over IPv6
|
|
|
+
|
|
|
+STP / RSTP support (802.1d) added to the EthernetSwitch:
|
|
|
+
|
|
|
+ - STP: added IEEE 802.1D-1998 implementation of Spanning Tree Protocol.
|
|
|
+ The source code is based on the ANSA (https://github.com/kvetak/ANSA)
|
|
|
+ implementation.
|
|
|
+
|
|
|
+ - RSTP: added IEEE 802.1D-2004 implementation of Spanning Tree Protocol.
|
|
|
+ The source code is based on Juan Luis Garrote Molinero's implementation
|
|
|
+ from INETMANET.
|
|
|
+
|
|
|
+ - Interfaces can be configured using the new L2NetworkConfigurator module.
|
|
|
+ This module allows one to configure network scenarios at Layer 2.
|
|
|
+
|
|
|
+ - Replaced the EtherSwitch relay unit with a new, STP/RSTP capable one.
|
|
|
+ The CPU and memory modelling are no longer supported in this relay unit.
|
|
|
+
|
|
|
+Nodes automatically pick-up the network configuration on restart:
|
|
|
+
|
|
|
+ - An IPv4NodeConfigurator module has been added to hosts, which is responsible
|
|
|
+ for configuring the host on restart based on information stored in the
|
|
|
+ IPv4NetworkConfigurator module.

+INetFilter::IHook API:
|
|
|
+
|
|
|
+ Modules can now hook into the IP module with the new 'NetFilter' API.
|
|
|
+ Routing protocols can be implemented now without modifying the IP
|
|
|
+ module's code. ManetRoutingBase, InternetCloud and ARP have been updated
|
|
|
+ to use the new 'NetFilter' API.
|
|
|
+
|
|
|
+Added new routing protocols:
|
|
|
+
|
|
|
+ - RIP (networklayer/routing/rip)
|
|
|
+ - GPSR (networklayer/routing/gpsr)
|
|
|
+ - DYMO (networklayer/routing/dymo)
|
|
|
+ These protocols use INetFilter::IHook, too.
|
|
|
+
|
|
|
+Revised Mobility code:
|
|
|
+
|
|
|
+ Split the 'models' directory into multiple directories:
|
|
|
+ - contract - specifies the interface of mobility models
|
|
|
+ - common - shared files among mobility models that are not complete
|
|
|
+ mobility models
|
|
|
+ - static - mobility models that actually don't move
|
|
|
+ - single - mobility models controlling only one moving object
|
|
|
+ - group - mobility models controlling multiple interlinked moving objects
|
|
|
+
|
|
|
+Radio:
|
|
|
+
|
|
|
+ Added the Stanford University Interim radio propagation model contributed
|
|
|
+ by Konrad Polys and Krzysztof Grochla.
|
|
|
+
|
|
|
+Other, smaller changes:
|
|
|
+
|
|
|
+ - Added ILifecycle support to most applications
|
|
|
+ - Renamed AppBase to ApplicationBase and moved to 'common'.
|
|
|
+ - UDP: added option to specify the source address of the sent datagram
|
|
|
+ - UDPBasicBurst: added bool parameter: excludeLocalDestAddresses
|
|
|
+ - UDPVideoStreamCli: use stages in initialize
|
|
|
+ - UDPApp*: Added AppBase and subclassed UDP apps from it.
|
|
|
+ Binds sockets at startTime and closes them at stopTime.
|
|
|
+ - EtherApp* bugfixes
|
|
|
+ - Added a command to set TCP queue length threshold. TCP will notify the
|
|
|
+ application if it is ready to transmit more bytes.
|
|
|
+ - registerSignal() calls were moved from initialize() to static
|
|
|
+ variable declarations.
|
|
|
+ - Added/fixed @signal declarations, fixed the type of emitted values.
|
|
|
+ - httptools: removed the fileExists() function.
|
|
|
+ - New logging mechanism + EV handling in preparation for the new OMNeT++ 5.0
|
|
|
+ logging mechanism.
|
|
|
+ - IPv4Route/IPv6Route: added administrative distance field
|
|
|
+ - Added IPv6 header serializer (so ext interfaces can be used with IPv6, too)
|
|
|
+ - Invalid access of message pointers fixed in: OSPF, SCTP, DHCP, PingApp
|
|
|
+
|
|
|
+ - Battery: code review, small fixes.
|
|
|
+ - Revised init stages in all modules
|
|
|
+ - Many smaller fixes and improvements (see the ChangeLog files for further detail.)

|
+INET-2.2.0 (August 22, 2013)
|
|
|
+----------------------------
|
|
|
+
|
|
|
+The main highlight of this release is the long-sought support for
|
|
|
+simulating node shutdown/restart events for network nodes.
|
|
|
+This release requires OMNeT++ 4.2 or later.
|
|
|
+
|
|
|
+New features:
|
|
|
+
|
|
|
+1. Lifecycle infrastructure.
|
|
|
+
|
|
|
+ For node shutdown/crash/startup/etc, a LifecycleOperation (e.g.
|
|
|
+ NodeShutdownOperation) is applied to the submodule tree of the node
|
|
|
+ (host or router) by LifecycleController. Each module can decide how
|
|
|
+ to handle the operation and how to store the resulting state (up/down,etc).
|
|
|
+ Operations can be multi-stage, and don't need to complete immediately
|
|
|
+ (i.e. they can take nonzero simulation time and multiple events to complete).
|
|
|
+
|
|
|
+ Network nodes now also have a status submodule (type NodeStatus) with the sole
|
|
|
+ purpose of storing the whole node's status (up/down) and displaying it
|
|
|
+ via icons.
|
|
|
+
|
|
|
+ - classes: ILifecycle, LifecycleOperation (NodeOperation, InterfaceOperation),
|
|
|
+ LifecycleController, NodeStatus
|
|
|
+ - NodeStatus module to store the network node's status (up or down)
|
|
|
+ - added optional NodeStatus submodule to NodeBase
|
|
|
+ - added a test for the basic Lifecycle infrastructure
|
|
|
+
|
|
|
+ We also removed obsolete ways of shutdown/restart: FailureManager, PowerControl,
|
|
|
+ LDP_FAILED/RSVP_FAILED, etc.
|
|
|
+
|
|
|
+2. Static IP4 configuration:
|
|
|
+
|
|
|
+ A new module, IPv4NodeConfigurator was added to IPv4NetworkLayer. This module
|
|
|
+ is necessary because IPv4NetworkConfigurator cannot configure the node after
|
|
|
+ a restart (see newly introduced node lifecycle operations above), since
|
|
|
+ being a global module, it doesn't know about node lifecycle events. The new
|
|
|
+ module listens to node lifecycle events, and configures the node's routing
|
|
|
+ table and interfaces according to configuration computed by the network's
|
|
|
+ global IPv4NetworkConfigurator module. Initialization-time node configuration
|
|
|
+ is also carried out by the new module.
|
|
|
+
|
|
|
+3. Added TCP Vegas and Westwood algorithms.
|
|
|
+
|
|
|
+ The implementation is a slightly improved version of a 2013 workshop submission:
|
|
|
+ "INET framework extensions for TCP Vegas and TCP Westwood", Maria Fernandez,
|
|
|
+ Carlos Calafate, Juan-Carlos Cano and Pietro Manzoni. OMNeT++ Workshop, 2013.
|
|
|
+ http://www.omnet-workshop.org/2013/uploads/slides/OMNeT-Workshop2013-SP-4.pdf
|
|
|
+
|
|
|
+4. Added IdealWirelessNic (IdealRadio + IdealWirelessMac) and IdealWirelessFrame msg.
|
|
|
+
|
|
|
+ This is a highly abstracted wireless NIC that consists of a unit disk radio
|
|
|
+ and a trivial MAC protocol. It offers simplicity for scenarios where Layer 1
|
|
|
+ and Layer 2 effects can be completely ignored, for example testing the basic
|
|
|
+ functionality of a wireless ad-hoc routing protocol.
|
|
|
+
|
|
|
+ The most important parameter this model accepts is the transmission range.
|
|
|
+ When a radio transmits a frame, all other radios within transmission range
|
|
|
+ will receive the frame correctly, and radios out of range will not be
|
|
|
+ affected at all. There are no collisions -- a radio can simultaneously
|
|
|
+ receive any number of frames, and also transmit a single frame at the same time.
|
|
|
+
|
|
|
+5. STCP received several new features (patches submitted by Irene Ruengeler):
|
|
|
+ - 8 new strategies for SCTP stream scheduling
|
|
|
+ - SCTP Stream Reset (RFC 6525)
|
|
|
+ - SCTP Authentication (RFC 4895)
|
|
|
+ - Add-IP feature for SCTP (RFC 5061)
|
|
|
+ - NR_SACK feature to SCTP
|
|
|
+ - Partial Reliability SCTP (RFC 3758)
|
|
|
+ - SCTP packet drop feature (draft-stewart-sctp-pktdrprep-15.txt)
|
|
|
+ - SCTP "sack immediately" feature (draft-ietf-tsvwg-sctp-sack-immediately)
|
|
|
+ - several alternatives to send fast retransmissions on SCTP
|
|
|
+
|
|
|
+6. Loopback interface added
|
|
|
+
|
|
|
+ Loopback used to be a special case inside the IPv4/IPv6 modules, now it
|
|
|
+ is handled completely like any other interface, with a separate Loopback
|
|
|
+ module.
|
|
|
+
|
|
|
+7. EtherSwitch, AccessPoint:
|
|
|
+
|
|
|
+ Bare EtherMAC modules have been replaced with EthernetInterface, so that
|
|
|
+ external queues can be used (useful for e.g. QoS).
|
|
|
+
|
|
|
+8. InterfaceTable, NIC, NetworkLayer:
|
|
|
+
|
|
|
+ Revert to earlier behavior of determining networkLayerGateIndex.
|
|
|
+ Now the module connected to a NIC *must* have gate vectors called ifIn and ifOut.
|
|
|
+ If it doesn't, the code decides that the NIC is *not* directly connected to
|
|
|
+ a network layer, and leaves networkLayerGateIndex unfilled.
|
|
|
+
|
|
|
+Other, smaller changes:
|
|
|
+
|
|
|
+ - MANET protocols have been synchronized with the INETMANET project
|
|
|
+ - NodeBase: added optional battery (off by default)
|
|
|
+ - UDP: implemented ReuseAddress option (it's like SO_REUSEADDR socket
|
|
|
+ option in Linux). If ReuseAddress is set to true on two sockets,
|
|
|
+ then they can bind to the same local address/port.
|
|
|
+ - PingApp and other apps: for the stopTime parameter, 'none' is now represented
|
|
|
+ by -1, not 0. As this is the default setting, likely very few simulations
|
|
|
+ (ini files) are affected.
|
|
|
+ - IPv4NetworkConfigurator: added @groups to <interface> (ie. multicast groups
|
|
|
+ can now be also specified in the <interface> element, not only in a separate
|
|
|
+ <multicast-group> element)
|
|
|
+ - in many simulation examples, .irt files were replaced by IPv4NetworkConfigurator XML.
|
|
|
+ - EtherMACFullDuplex: wait IFG *after* frames, not before.
|
|
|
+ - Ieee80211Mac: added signals declarations and statistics in the NED file
|
|
|
+ - EthernetInterface: the encap submodule was made replaceable ("like IEtherEncap")
|
|
|
+ - NED: Added InterfaceTable unconditionally to bridge devices, as it is currently
|
|
|
+ required by IPv4NetworkConfigurator. Also added NotificationBoard required by
|
|
|
+ InterfaceTable.
|
|
|
+ - IPv4NetworkConfigurator: Changed to support mixed wired and wireless LANs
|
|
|
+ for autoconfiguration.
|
|
|
+ - Fixed IPv4NetworkConfigurator bug sometimes not being able to assign addresses.
|
|
|
+ Changed to assign most constrained addresses first.
|
|
|
+ - RTPHost was moved from src/transport to src/nodes/, and changed to be based
|
|
|
+ on StandardHost
|
|
|
+ - TurtleMobility: Fixed getting the position from a mobility signal listener
|
|
|
+ during initialization. The script was resumed before initialize() finished,
|
|
|
+ resulting in incorrect positioning.
|
|
|
+ - StaticGridMobility: Added new parameters to specify the number of rows/columns
|
|
|
+ and the horizontal/verical separation between the nodes. Note that the way
|
|
|
+ the node positions are calculated has changed. You may need to update your
|
|
|
+ INI files (see the NED file for more info.)
|
|
|
+ - Many smaller fixes and improvements
|
|
|
+
|
|

|
|
|
+INET-2.1.0 (Jan 31, 2013)
|
|
|
+-------------------------
|
|
|
+
|
|
|
+NEW:
|
|
|
+
|
|
|
+ - Added a new module to model an "internet cloud". The component can
|
|
|
+ be configured to model packet delay, datarate and drop probability
|
|
|
+ between each input-output interface pair. The parameter matrix
|
|
|
+ is provided as an XML configuration file. See the README file
|
|
|
+ in src/nodes/internetcloud for further details.
|
|
|
+ - New SimpleVoIPReceiver/Sender applications that gather MOS (Mean
|
|
|
+ Opinion Score) for measuring voice quality.
|
|
|
+ - Added HNA support to the Batman protocol (MANET)
|
|
|
+
|
|
|
+CHANGED:
|
|
|
+
|
|
|
+Applications:
|
|
|
+ - PingApp: Shows the configured destination address at the end of the
|
|
|
+ simulation.
|
|
|
+ - TCPBasicClientApp: bugfix #611: simulation generated an ASSERT if
|
|
|
+ numRequestsPerSession parameter value larger than 1.
|
|
|
+ - TcpApp: socket state is now shown on the GUI (in Echo, Sink and Session apps.)
|
|
|
+ - VoipTool: was renamed to VoIPStream (The actual module names are
|
|
|
+ VoIPStreamSender/Receiver.)
|
|
|
+
|
|
|
+Ethernet:
|
|
|
+ - Transmission channel's 'disabled' parameter is now correctly handled in
|
|
|
+ EtherMacBase.
|
|
|
+
|
|
|
+Ieee80211Mac:
|
|
|
+ - Better parameter processing in MAC: error is thrown if an undefined value
|
|
|
+ is specified for the opmode or autoBitrate parameters.
|
|
|
+ - Added the Ieee80211Descriptor class to assign modulation speed
|
|
|
+ and type for the different opModes.
|
|
|
+ - Bugfix: Default bitrate for opMode 'p' was incorrectly set.
|
|
|
+
|
|
|
+BGP:
|
|
|
+ - Minor optimizations
|
|
|
+ - Bugfix: The text in specification "sets the ConnectRetryTimer to zero" means:
|
|
|
+ restart this timer. The _connectRetryTime member now stores the timeout value.
|
|
|
+
|
|
|
+Manetrouting:
|
|
|
+ - updated documentation
|
|
|
+ - replaced Uint128 with ManetNetworkAddress
|
|
|
+ - removed:
|
|
|
+ - unused ManetTimer and BatmanTimer class
|
|
|
+ - unused static variables
|
|
|
+ - isIpLocalAddress(), uses isLocalAddress()
|
|
|
+ - convertAddressToString()
|
|
|
+ - getXPos(), getYPos() functions, you should use getPosition()
|
|
|
+ instead.
|
|
|
+ - redesigned coordinate and speed storage and access.
|
|
|
+ replaced double x,y with a Coord. getDirection() now returns the
|
|
|
+ speed vector (as a Coord)
|
|
|
+ - getters returns UNSPECIFIED_ADDRESS if addrType==UNDEFINED
|
|
|
+ - merged sendToIp() code into a common base function sendToIpOnIface()
|
|
|
+
|
|
|
+AODV:
|
|
|
+ - AODV's hand-written descriptors were replaced with generated ones
|
|
|
+ [with A.Varga]
|
|
|
+ - aodv_msg_struct.h: added getter methods expected by the generated
|
|
|
+ descriptors removed hand-written aodv_msg_struct_descriptor.cc
|
|
|
+
|
|
|
+Batman:
|
|
|
+ - Updated and expanded documentation
|
|
|
+ - Updated the code to match the latest available "batmand" version.
|
|
|
+ - Numerous optimizations
|
|
|
+ - Fixed several memory leaks
|
|
|
+ - Fixed routing table corruption and possible crash when multiple
|
|
|
+ radios were used in a single host
|
|
|
+ - Fixed decapsulation of incoming packets. Now it checks for the
|
|
|
+ type of decapsulated packet.
|
|
|
+ - Fix for a problem when aggregated batman packets were
|
|
|
+ dropped erronously.
|
|
|
+ - Added HNA support. Nodes can advertise external networks,
|
|
|
+ so traffic towards those networks can be routed correctly.
|
|
|
+ Use the announcedNetworks parameter to specify multiple connected
|
|
|
+ external networks.
|
|
|
+ - Added SourceModifier script to help the conversion from the original
|
|
|
+ batmand code.
|
|
|
+ - fixes spaces, tabs and empty lines
|
|
|
+ - replaces some c-style structs to c++-style classes
|
|
|
+ - replaces some batmand specified list manipulators with c++ code
|
|
|
+ - replaces malloc/free with new/delete
|
|
|
+ - removes prof_start()/prof_stop() calls
|
|
|
+
|
|
|
+Examples:
|
|
|
+ - Added a new simulation with wired and wireless hosts exchanging UDP
|
|
|
+ data via an AccessPoint. It shows how to use the IPv4NetworkConfigurator
|
|
|
+ to mix wired and wireless networks.
|
|
|
+ - Fixes for BGP examples.
|
|
|
+ - New example to demonstrate HNA support in Batman.
|
|
|
+ - Hostautoconf examample moved to the adhoc folder.
|
|
|
+
|
|
|
+Other changes:
|
|
|
+ - Uint128 class was removed. Use ManetNetworkAddress class instead.
|
|
|
+ - Visual changes in StandardHost/NodeBase: utility module icons are
|
|
|
+ now smaller and wlan[]/PingApp[] modules are displayed in a row.
|
|
|
+ - NodeBase: it is possible to use mobility module even if numRadios = 0
|
|
|
+ - Added check for detecting too small netmask parameter value in
|
|
|
+ HostAutoConfigurator
|
|
|
+ - PacketDump: TCP header option fix (dumped only in verbose mode.)
|
|
|
+ - Bugfix #620. The module pointer returned by a ModuleAccess class is
|
|
|
+ now cached only if get() was used. For get(module) no caching is done.
|
|
|
+ - MACAddress: made the constructor explicit so we will not see
|
|
|
+ unexpected implicit conversions in future
|
|
|
+ - IPv6Address: removed Uint128 related functions and added an
|
|
|
+ additional constructMask() method
|
|
|
+ - headerserializers: compile fix for Visual C++ 10.0 and later
|
|
|
+ - Pcap now records on ALL interfaces by default (including external IFs).
|
|
|
+ Added Enter_Method for better error reporting if a packet cannot be
|
|
|
+ serialized. Also added an icon for PcapRecorder.
|
|
|
+ - Several TCP related fixes.
|
|
|

|
|
+INET-2.0.0 (August 7, 2012)
|
|
|
+---------------------------
|
|
|
+
|
|
|
+If you are upgrading from an earlier INET version (i.e. INET 20111118),
|
|
|
+expect to have to revise your existing omnetpp.ini files and possibly
|
|
|
+NED/C++ files as well.
|
|
|
+
|
|
|
+Changes since 1.99.5:
|
|
|
+
|
|
|
+The DHCP protocol received several fixes. It is now possible to use DHCP
|
|
|
+with both wired and wireless interfaces.
|
|
|
+
|
|
|
+MANET routing protocols updated from INETMANET-2.0 @ 9a3dc7a
|
|
|
+OLSR protocol received several patches allowing it to work with multiple
|
|
|
+radios. It can work now on both wired and wireless interfaces.
|
|
|
+
|
|
|
+Ieee80211:
|
|
|
+ - bugfix: The latest version of INET (1.99.5) contained a bug where
|
|
|
+ speed values for 11MBps and 12MBps were swapped.
|
|
|
+ - A new "bitrate" parameter was added to the Ieee80211Nic module.
|
|
|
+ The Radio and MAC module uses this bitrate to set thir own bitrate
|
|
|
+ value. Its default value is 11Mbps for 802.11b, 27Mbps for 802.11p
|
|
|
+ and 54Mbps for 802.11g and 802.11a. (i.e. the default bitrate depends
|
|
|
+ on the opMode parameter) This can avoid potential configuration
|
|
|
+ inconsitencies. UPDATE all your INI files accordingly.
|
|
|
+
|
|
|
+The Ethernet module now throws an error message if two ethernet ports are
|
|
|
+connected using an IdealChannel. Previously it just silently ignored the
|
|
|
+connection that was definitely against the "least surprise" principle.
|
|
|
+
|
|
|
+A new "Delayer" module has been added and DropsGenerator and DuplicatesGenerator
|
|
|
+has been renamed to OrdinalBasedDropper and OrdinalBasedDuplicator respectively.
|
|
|
+These modules implement the IHook module interface and can be installed inside
|
|
|
+hosts to induce different packet errors. IHook modules can be inserted
|
|
|
+between the network and link layer protocols.
|
|
|
+
|
|
|
+The Ext-interface, TraCI, Mobility and Ping modules received some minor fixes.
|
|
|
+See ChangeLogs in individual source folders for more information.

|
|
|
+
|
|
|
+INET-1.99.5 (June 22, 2012)
|
|
|
+---------------------------
|
|
|
+
|
|
|
+This is the final testing version of the 1.99.x series leading to the 2.0
|
|
|
+release. Requires OMNeT++ 4.2 (version 4.2.2 suggested).
|
|
|
+
|
|
|
+Several OSPF fixes and changes in configuration (see the ChangeLog file
|
|
|
+in the OSPF folder for details):
|
|
|
+ - improved error detection in xml config files
|
|
|
+ - replaced the ospfConfigFile string-type ned parameter with ospfConfig parameter (xml type)
|
|
|
+ - uses IPvXAddressResolver for reading IP address and IP netmask values from xml
|
|
|
+ - uses @name instead @id to identify the routers in the xml config
|
|
|
+ - most attributes in xml config became optional, and default values
|
|
|
+ come from ned the parameters of OSPFRouting (with same name)
|
|
|
+ - modified xml schema: converted most subnodes to attributes
|
|
|
+ - Added etc/OSPFold_to_OSPFnew.xsl for converting the old xml format to new, and
|
|
|
+ converted all the ospf config files to the new format in the examples folder
|
|
|
+ (after using the converter you must convert router@id to router@name by hand).
|
|
|
+ - added @toward attribute to XML for easier interface specification
|
|
|
+ old: interfaces were specified by their name (e.g. ifName="eth0").
|
|
|
+ new: interfaces can be specified either by their name (e.g. ifName="eth0"),
|
|
|
+ or by the name of a module the interface is connected to (e.g. toward="Area3.N9")
|
|
|
+ - fixed OSPF.xsd schema
|
|
|
+
|
|
|
+Queueing components:
|
|
|
+ The networklayer/queue folder has moved to linklayer/queue folder as
|
|
|
+ queues are mostly used in linklayer. This is a new framework that can be
|
|
|
+ used to create more complex systems.
|
|
|
+ Old queuing components has been removed:
|
|
|
+ - DropTailQosQueue, REDQueue, WeightedFairQueue
|
|
|
+ - IQoSClassifier (moved to linklayer/ieee80211/mac)
|
|
|
+ - BasicDSCPClassifier
|
|
|
+ Some of them can be substituted by compound modules composed of these newly
|
|
|
+ added components:
|
|
|
+ - FIFOQueue
|
|
|
+ - REDDropper
|
|
|
+ - ThresholdDropper
|
|
|
+ - PriorityScheduler
|
|
|
+ - WRRScheduler
|
|
|
+ For example REDQueue is a combination of a REDDropper and a FIFOQueue,
|
|
|
+ and DropTailQosQueue is a combination of some classifier, DropTailQueues,
|
|
|
+ and a PriorityScheduler. Read the INET Manual (in doc folder) for more
|
|
|
+ information about the usage of these modules.
|
|
|
+
|
|
|
+Brand new Differentiated Services component (using the Queueing framework)
|
|
|
+that is implementing the following standards:
|
|
|
+ - RFC 2474: Definition of the Differentiated Services Field (DS Field) in
|
|
|
+ the IPv4 and IPv6 Headers
|
|
|
+ - RFC 2475: An Architecture for Differentiated Services
|
|
|
+ - RFC 2597: Assured Forwarding PHB Group
|
|
|
+ - RFC 2697: A Single Rate Three Color Marker
|
|
|
+ - RFC 2698: A Two Rate Three Color Marker
|
|
|
+ - RFC 3246: An Expedited Forwarding PHB (Per-Hop Behavior)
|
|
|
+ - RFC 3290: An Informal Management Model for Diffserv Routers
|
|
|
+
|
|
|
+
|
|
|
+New send method on UDPSocket now allows to specify on which interface
|
|
|
+the packets should be sent out.
|
|
|
+
|
|
|
+Added DHCP protocol implementation by Juan Carlos Maureira
|
|
|
+taken over from INETMANET-2.0 @ 7fb431b. It can be deployed just
|
|
|
+like any other UDP apps.
|
|
|
+
|
|
|
+MANET routing protocols updated from INETMANET-2.0 @ 7fb431b
|
|
|
+The whole manetrouting directory was taken over.
|
|
|
+
|
|
|
+Mobility: Added two new mobility models:
|
|
|
+ - TraCI + TraCIScenarioManager to connect with an external server
|
|
|
+ - LinearNodeDistribution - static hosts in a single line in
|
|
|
+ ANY direction
|
|
|
+
|
|
|
+IPv4Route: removed the "type" attribute from the routing entries
|
|
|
+
|
|
|
+VoIPTool: Now compiles with the latest version of ffmpeg libs
|
|
|
+
|
|
|
+IGMPv2: external routers attached to the IGMP module are now
|
|
|
+responsible for implementing the IGMP router logic (emitting queries
|
|
|
+and processing group membership reports). In this case the IGMP
|
|
|
+module passes all incoming IGMP messages to the external router.
|
|
|
+
|
|
|
+Updated 802.11 model from INETMANET-2.0 @ 7fb431b (minor bugfixes)
|
|
|
+All files are synced. The following features were omitted:
|
|
|
+MULTIQUEUES, HWMP and MESH networking related code.
|
|
|
+The default wireless NIC is now using the latest 802.11 code from
|
|
|
+INETMANET. The Ieee80211NewNic was renamed to Ieee80211Nic. With
|
|
|
+the new NIC it is now possible set the operating mode (a,b,g,p)
|
|
|
+The original Ieee80211 implementation was removed to avoid confusion.
|
|
|
+
|
|
|
+The ancient 802.11 implementation from the mobility framework was removed
|
|
|
+(i.e. the mf80211 directory).
|
|
|
+
|
|
|
+Added HostAutoConfigurator module (should be added inside a host)
|
|
|
+This configurator is deprecated and should be used ONLY if the hosts are
|
|
|
+dynamically created/deleted during the simulation. Otherwise please use the
|
|
|
+new IPv4NetworkConfigurator.
|
|
|
+
|
|
|
+IPv4NetworkConfigurator: Examples have been updated to use this configurator.
|
|
|
+XML configuration format changes:
|
|
|
+ - added @among attribute for interface and multicast-group entries:
|
|
|
+ "among='X Y Z'" means "hosts='X Y Z' towards='X Y Z'"
|
|
|
+ - added @metric attribute for interface entry in XML
|
|
|
+ - added @id attribute for wireless entry
|
|
|
+ - several smaller bugfixes and documentation changes (see ChangeLog
|
|
|
+ in the directory)
|
|
|
+
|
|
|
+IPv4 fix: subnet directed broadcast (e.g. 192.168.1.255) works now:
|
|
|
+When the datagram reaches the router of the subnet, it should
|
|
|
+be forwarded as a link layer broadcast.
|
|
|
+
|
|
|
+Changes in link layer
|
|
|
+ - added INic moduleinterface, all other network interfaces should
|
|
|
+ implement this
|
|
|
+ - renamed the netwIn, netwOut gates to upperLayerIn, upperLayerOut
|
|
|
+
|
|
|
+Small fixes in MACAddress, PPP, IPv4NetworkConfigurator, VoIPTool,
|
|
|
+Mobility, BatteryModule

+INET-1.99.4 (March 20, 2012)
|
|
|
+----------------------------
|
|
|
+
|
|
|
+This version contains mainly bugfixes, plus some features that did not make
|
|
|
+into the previous release. Requires OMNeT++ 4.2 (version 4.2.1 suggested).
|
|
|
+
|
|
|
+- Added IPv4NetworkConfigurator, a new network configurator for IPv4
|
|
|
+
|
|
|
+ This is intended to replace both routing files (.irt/.mrt) and
|
|
|
+ specialized network configurators like FlatNetworkConfigurator,
|
|
|
+ and do much more.
|
|
|
+
|
|
|
+ Covers address assignment (manual, automatic), adding manual routes,
|
|
|
+ setting up static routing, optimizing the routing tables, etc.
|
|
|
+ Unlike FlatNetworkConfigurator, it will generate per-interface
|
|
|
+ addresses. Wireless networks are also supported.
|
|
|
+
|
|
|
+- Added an IGMPv2 implementation, based on code contributed by Jesse Jones
|
|
|
+
|
|
|
+Changes in IPv4 multicast routing:
|
|
|
+- We now use reverse path forwarding (routing entry contains
|
|
|
+ source address/mask, multicast group, parent (incoming) interface
|
|
|
+ and the set of child (outgoing) interfaces).
|
|
|
+- The new routing table enables to specify a separate multicast
|
|
|
+ routing tree per source network and multicast group. (Old
|
|
|
+ implementation used a common tree for each source.) The multicast
|
|
|
+ routing tree is represented by IPv4MulticastRoute entries.
|
|
|
+- IRoutingTable has been extended with methods manipulating the
|
|
|
+ multicast routing entries. Notifications are generated, when
|
|
|
+ the multicast routing table changes.
|
|
|
+- IPv4 multicast routing algorithm uses the multicast routes
|
|
|
+ for forwarding decisions.
|
|
|
+- When HL does not specify the multicast interface for outgoing
|
|
|
+ datagrams, then it is selected according to the routing table
|
|
|
+ or the source address of the datagram.
|
|
|
+
|
|
|
+Change from previous behavior:
|
|
|
+- packets sent to a multicast address from higher layer: it used
|
|
|
+ to go out on each interface that had a matching route in the
|
|
|
+ routing table (unless mcast interface was specified by HL).
|
|
|
+ Now it only goes out on the first match route's interface;
|
|
|
+ if there's no match it goes out on the 1st multicast interface
|
|
|
+ (unless mcast interface was specified by HL). If you want to
|
|
|
+ send on multiple interfaces, you have to send multiple packets
|
|
|
+ from the higher layer.
|
|
|
+
|
|
|
+- multicast forwarding: no longer takes into account the routes
|
|
|
+ in the unticast routing table that have mcast destinations.
|
|
|
+ Only the (new format) multicast table is used. This new
|
|
|
+ multicast routing table can only be configured with
|
|
|
+ IPv4NetworkConfigurator, routing files don't support it.
|
|
|
+- mobility: fixed infinite loop when nextChange is set to current
|
|
|
+ simulation time
|
|
|
+
|
|
|
+- base: Added createNode(), createLink() factory methods to Topology class.
|
|
|
+
|
|
|
+- Enhancements in IPvXAddressResolver. The new resolver allows you
|
|
|
+ to specify an interface based on which module the interface is
|
|
|
+ connected to.
|
|
|
+
|
|
|
+- Added a RoutingTableRecorder module that records all the changes
|
|
|
+ in the routing table to a file.
|
|
|
+
|
|
|
+- OSPF & BGP fix:
|
|
|
+ - gateway is now correcty set on routing table entries.
|
|
|
+ - eliminated redundant nextHop field from routing table entries
|
|
|
+
|
|
|
+- Fixed routing table change notifications.
|
|
|
+
|
|
|
+- Added printMulticastRoutingTable() to IRoutingTable
|
|
|
+
|
|
|
+- Added IPingApp interface and support for more than one PingApp
|
|
|
+ in a host.
|
|
|
+
|
|
|
+- Changes in the UDP socket API:
|
|
|
+
|
|
|
+ The first call on an UDP socket do not need to be bind() or connect()
|
|
|
+ anymore. It is possible to create a socket and sending data immediately
|
|
|
+ by calling sendTo(). It is also possible to set socket options before
|
|
|
+ calling connect() or bind(). connect() can be called several times.
|
|
|
+ However the bind() call fails if the socket is already bound.
|
|
|
+
|
|
|
+- LDP: The LDP module now creates a separate UDP socket for each
|
|
|
+ multicast interface of the node, sets the multicast interface
|
|
|
+ on them, and sends a copy of LDP-Hellos via each socket.
|
|
|
+
|
|
|
+- ICMP messages are correctly handled now in all TCP implementations
|
|
|
+ (in LwIP and NSC, too)
|
|
|
+
|
|
|
+See ChangeLogs in individual source folders for more information.

|
+INET-1.99.3 (Feb 22, 2012)
|
|
|
+--------------------------
|
|
|
+
|
|
|
+With this release, we have started a review of all basic protocol modules in
|
|
|
+the INET Framework, fixing bugs, refactoring for clarity and maintainability,
|
|
|
+and implementing commonly needed missing features. A testing framework is also
|
|
|
+falling into place. We have added ChangeLog files in each source directory
|
|
|
+to make it easier to follow things for end users and contributors alike, and
|
|
|
+we'll also be requiring ChangeLog entries from contributors who submit code
|
|
|
+patches. ChangeLogs also include a brief history of the corresponding
|
|
|
+components from the start; if you have fixes or amendments, please contact us.
|
|
|
+This version of INET requires OMNeT++ 4.2 (version 4.2.1 suggested).
|
|
|
+
|
|
|
+- Ethernet model improvements: EtherMAC refactored for better readability;
|
|
|
+ added reconnect support, better PAUSE support, support for 40 Gigabit and
|
|
|
+ 100 Gigabit Ethernet; several bugfixes; regression and validation tests
|
|
|
+
|
|
|
+- added predefined Ethernet link types: Eth10M, Eth100M, Eth1G, Eth10G,
|
|
|
+ Eth40G, Eth100G
|
|
|
+
|
|
|
+- IPv4 model improvements: better fragmentation and multicast support; IPv4
|
|
|
+ module refactored for readability and maintainability; several bugfixes
|
|
|
+
|
|
|
+- IPv4 routing table improvements: notification for routing entry changes
|
|
|
+ (routing entry objects no longer need to be immutable); lookup performance
|
|
|
+ optimization (routes are kept in decreasing prefix length order to speed up
|
|
|
+ longest prefix match); cleanup and bugfixes
|
|
|
+
|
|
|
+- IPv6 improvements: implemented Default Router Selection as specified in
|
|
|
+ RFC 4861 6.3.6 (round-robin); tunneling is now available without xMIPv6;
|
|
|
+ implemented datagram fragmentation/reassembly; IPv6 now works over PPP;
|
|
|
+ several other bug fixes
|
|
|
+
|
|
|
+- UDP: better multicast support and DSCP support (apps can specify ToS [IPv4] /
|
|
|
+ Traffic Class [IPv6] byte); bug fixes
|
|
|
+
|
|
|
+- PPPInterface, EthernetInterface: use queueType="" instead of queueType=
|
|
|
+ "NoQueue" to turn off external queue module and use internal queue.
|
|
|
+
|
|
|
+- Ieee80211, MANET routing: updated to latest INETMANET release:
|
|
|
+ radio: added support for noise generators and configurable error models;
|
|
|
+ 802.11: Airtime Link Metric support; duplicate frame detection / filtering;
|
|
|
+ support for prioritizing of multicast frames
|
|
|
+
|
|
|
+- added WeightedFairQueue from INETMANET
|
|
|
+
|
|
|
+- removed Ieee802.11 Mesh feature. It depended on too many upper layer
|
|
|
+ protocols and features.
|
|
|
+
|
|
|
+- statistics (@statistic properties) cleaned up in all modules: standardized
|
|
|
+ on lower case statistics titles; record packet counts in a less confusing
|
|
|
+ way (NOT as rcvdPkBytes:count); cleaned up recorder lists
|
|
|
+
|
|
|
+- miscellaneous: timer usage optimized in DYMO_FAU; revised PingApp, e.g.
|
|
|
+ printPing is now turned off by default; numerous bug fixes and improvements
|
|
|
+
|
|
|
+- added a test suite (tests/); it contains fingerprint tests (for regression
|
|
|
+ testing); smoke tests (crude regression tests); statistical tests (for
|
|
|
+ validation); unit tests (of classes/modules); and other tests. We make most
|
|
|
+ use of fingerprint tests, so they are probably in the best state.
|
|
|

|
+INET-1.99.2 (Nov 18, 2011)
|
|
|
+--------------------------
|
|
|
+
|
|
|
+Requires OMNeT++ 4.2 (final).
|
|
|
+
|
|
|
+- Integrated Kristjan Jonsson's HttpTools project,
|
|
|
+ http://code.google.com/p/omnet-httptools/
|
|
|
+
|
|
|
+- The mobility models have been revised and brought in sync with their
|
|
|
+ MiXiM versions; added 3D coordinate system from MiXim; added MoBAN mobility
|
|
|
+ model from MiXiM.
|
|
|
+
|
|
|
+- UDP: multicast, broadcast and ttl support; bugfixes; heavy API changes.
|
|
|
+ It is now possible to receive broadcasts and multicasts. Implemented support
|
|
|
+ for the following socket options: time-to-live (unicast and multicast),
|
|
|
+ broadcast, multicast output interface, join multicast group, leave multicast
|
|
|
+ group. Connect without bind is now supported (used to be an error).
|
|
|
+ The cost of the above is changes in the way you talk to the UDP module:
|
|
|
+ UDPControlInfo has been split to several classes (UDPBindCommand, UDPConnect-
|
|
|
+ Command, UDPSendCommand, etc.), and the UDPSocket class has been redesigned.
|
|
|
+ Check transport/udp/ChangeLog for detailed information.
|
|
|
+
|
|
|
+- Apps: some standardization of parameter names, so that various modules don't
|
|
|
+ call the same thing differently. Introduced the following names:
|
|
|
+ 'startTime', 'stopTime', 'sendInterval', 'localAddress', 'localPort'.
|
|
|
+ E.g. the following parameters became 'sendInterval': 'messageFreq',
|
|
|
+ 'waitTime', 'packetInterval', 'interval', and 'waitInterval'.
|
|
|
+
|
|
|
+- Added a 'stopTime' parameter to several apps: TelnetApp, UDPBasicApp,
|
|
|
+ TCPBasicClientApp, IPvXTrafGen, EtherAppCli
|
|
|
+
|
|
|
+- UDPBasicBurst revised
|
|
|
+
|
|
|
+- Removed Blackboard (it was obsolete and out of use)
|
|
|
+
|
|
|
+- Numerous bugfixes.
|
|
|
+
|
|

|
|
|
+INET-1.99.1 (May 27, 2011)
|
|
|
+--------------------------
|
|
|
+
|
|
|
+This is a beta of a major feature release, with new models and a lot of
|
|
|
+incompatible changes. It requires at least OMNeT++ 4.2b2.
|
|
|
+If you are upgrading from an earlier INET version, expect to have
|
|
|
+to revise your existing simulations.
|
|
|
+
|
|
|
+- INET can now be compiled with various parts turned off. This is based on
|
|
|
+ the new OMNeT++ Project Features facility, avaiable from 4.2b2, see
|
|
|
+ http://www.omnet-workshop.org/2011/uploads/slides/OMNeT_WS2011_S3_P1_Varga.pdf
|
|
|
+ slides 9-13. INET project features are defined in the .oppfeatures file;
|
|
|
+ features can be turned on/off in Project -> Project Features... in the IDE.
|
|
|
+ Not all features will compile on Windows: the ones that need to be turned off
|
|
|
+ on Windows are TCP_NSC, TCP_lwIP, VoIPTool, MANET Routing, Mesh Networking.
|
|
|
+
|
|
|
+- Integrated the following external packages: VoIPTool, xMIPv6.
|
|
|
+
|
|
|
+- Several components were taken over from INETMANET: MANET routing, combined
|
|
|
+ 802.11a/b/g/e model, 802.11 mesh networking, obstacle model, several
|
|
|
+ mobility models, battery model, globalARP feature. Multiple radio support
|
|
|
+ has also been added to INET, loosely based on the INETMANET solution.
|
|
|
+
|
|
|
+- NED-level cleanup of several compound modules: hosts, routers, NICs, APs,
|
|
|
+ switches, etc. There were a lot of very similar modules that differred in the
|
|
|
+ presence or type of one or more submodules, resulting in code duplication
|
|
|
+ and confusion in general. Many variants have been eliminated, and the
|
|
|
+ differences have been mapped to parameters, parametric or conditional
|
|
|
+ submodules.
|
|
|
+
|
|
|
+- ChannelController now deals only with radios and not hosts. This makes it
|
|
|
+ possible to have hosts with several radio interfaces. The radios are
|
|
|
+ registered/unregistered in the ChannelAccess module (previously host
|
|
|
+ registration was done by the mobility modules). ChannelControl/ChannelAccess
|
|
|
+ are now completely independent of the mobility modules. This means that if
|
|
|
+ there is no mobility module present in a host, the host's displaystring
|
|
|
+ will be used to set the static positions of the radios.
|
|
|
+
|
|
|
+- Ethernet switch was moved under the linklayer/ethernet/switch directory.
|
|
|
+ EtherHostQ is now called EtherHost. To have no queue in the Ethernet host,
|
|
|
+ specify queueType="NoQueue" (which in fact inserts a dummy queue).
|
|
|
+ In EtherSwitch, EtherHost and inside the EthernetInterface the
|
|
|
+ csmacdSupport parameter can be used to switch between the full (EtherMAC)
|
|
|
+ and the simplified (EtherMACFullDuplex) implementation.
|
|
|
+
|
|
|
+- EthernetInterfaceFullDuplex removed. By default EthernetInterface is using
|
|
|
+ EtherMACFullDuplex, a simplified MAC that does not support CSMA/CD and works
|
|
|
+ only with point-to-point links. Use the EthernetInterface with
|
|
|
+ csmacdSupport=true to turn on CSMA/CD support (EtherMAC).
|
|
|
+
|
|
|
+- IPv4-related modules and classes whose names started with "IP" were renamed
|
|
|
+ to start with "IPv4", to be more explicit and more future-proof. IP->IPv4,
|
|
|
+ IPAddress->IPv4Address, IPControlInfo->IPv4ControlInfo, IPRoute->IPv4Route,
|
|
|
+ IPDatagram->IPv4Datagram, etc.
|
|
|
+
|
|
|
+- Renamed routingTableFile to routingTable in RoutingTable6. Added default
|
|
|
+ parameter value. You no longer need to specify **.routingTableFile =
|
|
|
+ xmldoc("empty.xml") and have an empty.xml file in the model directory.
|
|
|
+ OMNeT++ 4.2 supports the xml("<inlinexml/>") syntax; we now use that for
|
|
|
+ the default value.
|
|
|
+
|
|
|
+- New PcapRecorder module (in StandardHost) for recording traffic to a pcap file.
|
|
|
+ It is intended as a replacement for the old TCPDump module.
|
|
|
+
|
|
|
+- StandardHost and Router now have a common base (containing Link~ and
|
|
|
+ NetworkLayer) Wireless~ and AdhocHost is derived from StandardHost. All of
|
|
|
+ them (including Router) support multiple wireless, Ethernet, PPP and
|
|
|
+ external interfaces (i.e. multiple wireless radios are supported using
|
|
|
+ different channels)
|
|
|
+
|
|
|
+- Several modules - especially inside StandardHost - are now conditional
|
|
|
+ (using NED's new "conditional submodule" feature), and will be instantiated
|
|
|
+ only if needed. For example, TCP is only instantiated if there are TCP
|
|
|
+ applications configured for the host.
|
|
|
+
|
|
|
+- Router and StandardHost have optional mobility support. The mobility module
|
|
|
+ is created only if there are wireless cards present in the node (numRadios>0).
|
|
|
+ Of course WirelessHost and AdhocHost have mobility by default. You can configure
|
|
|
+ the mobility type using the "mobilityType" parameter. BasicMobility have
|
|
|
+ been renamed to NullMobility (resulting stationary nodes). There is a dummy
|
|
|
+ mobility type called NoMobility which does not have any C++ implementation.
|
|
|
+ Nodes that do not need mobility support (i.e. no radios) should set their type
|
|
|
+ to NoMobility.
|
|
|
+
|
|
|
+- FailedRouter has been removed (was a trivial node). BurstHost moved to the
|
|
|
+ example directory (it was not generic and was used only by a single example).
|
|
|
+ MobileHost has been removed; use AdhocHost instead as a drop-in replacement.
|
|
|
+
|
|
|
+- Network Interface Cards (Ieee80211Nic, EthernetInterface and PPPInterface)
|
|
|
+ now support input and output hook modules that implement the IHook interface.
|
|
|
+ Hooks are useful for simulating packet drops, duplication or measuring thruput.
|
|
|
+ The number of hook modules can be controlled with the numInputHooks /
|
|
|
+ numOutputHooks parameters, and the hook's type via typename.
|
|
|
+ An example: that installs two hooks in the input path of PPP:
|
|
|
+ **.ppp[*].numInputHooks = 2
|
|
|
+ **.ppp[*].inputHook[0].typename = "DropsGenerator"
|
|
|
+ **.ppp[*].inputHook[1].typename = "ThruputMeter"
|
|
|
+
|
|
|
+- Network interfaces can specify a queueType paramater. Possible values:
|
|
|
+ DropTailQueue, DropTailQoSQueue, REDQueue, NoQueue.
|
|
|
+ To disable queueing, use NoQueue: **.ppp[*].queueType = "NoQueue"
|
|
|
+
|
|
|
+- PPPInterfaceNoQueue and EthernetInterfaceNoQueue have been removed; use the
|
|
|
+ queueType="NoQueue" parameter in the interfaces.
|
|
|
+
|
|
|
+- TCP, UDP and SCTP implementations are now pluggable; you can select the
|
|
|
+ implementation with the tcpType, udpType and sctpType parameters in the host.
|
|
|
+ Modules must implement ITCP, IUDP and ISCTP interface and the specify
|
|
|
+ the implementing NED type in the parameter. At the moment SCTP and UDP
|
|
|
+ have only one implementation. TCP has TCP (the default INET implementation),
|
|
|
+ TCP_NSC (Network Simulation Cradle) and TCP_lwIP (the lightweight IP stack).
|
|
|
+
|
|
|
+- AccessPoint has been generalized. Now it supports both (multiple) wireless
|
|
|
+ and ethernet ports. Relaying between ethernet and wireless ports is now
|
|
|
+ supported. A relay unit is created only if more than one ports are present
|
|
|
+ in the AccessPoint, i.e. having a single radio and no ethernet connections
|
|
|
+ will fall back to a single wireless NIC without a relay unit. Having no radio
|
|
|
+ and several ethernet ports connected will practically result in an ethernet
|
|
|
+ switch.
|
|
|
+
|
|
|
+- Wireless NICs now should implement IWirelessNIC. Now we have only a single
|
|
|
+ Ieee80211Nic implementation instead of the 5 variants we have previously.
|
|
|
+ Management type (Adhoc, AccessPoint, Station, AccessPointSimplified and
|
|
|
+ StationSimplified) can be configured using the mgmtType parameter of the NIC
|
|
|
+ (instead of having separate NIC types for each.)
|
|
|
+
|
|
|
+- Multiple radios on independent channels are now supported by all nodes. See
|
|
|
+ the wireless/multiradio example.
|
|
|
+
|
|
|
+- The radio infrastucture have been refactored. All radios should now implement
|
|
|
+ the IRadio interface. They are now pluggable. RadioModel can be configured
|
|
|
+ also via a module parameter. The attenuationModel parameter was moved from
|
|
|
+ the radio to ChannelController (it is now global) and renamed to propagationModel.
|
|
|
+ Several new propagation model have been added (see NED file docs).
|
|
|
+
|
|
|
+- Removed the TCPSpoofingHost node. Use instead StandardHost with the
|
|
|
+ tcpType="TCPSpoof" parameter.
|
|
|
+
|
|
|
+- NAMTrace and NAMTraceWriter modules have been moved to the obsolete directory.
|
|
|
+ Turn on event logging instead and use the eventlog animator in the IDE. Event
|
|
|
+ logging can be turned on with --record-eventlog=true from the command line or
|
|
|
+ using the toolbar button in Tkenv. Once the .elog file is generated, right
|
|
|
+ click on it in the IDE and select Open with / Animation Player.
|
|
|
+
|
|
|
+- ChannelInstaller module has been removed. Implemented a ThruputMeteringChannel that
|
|
|
+ extends DatarateChannel. It adds thruputDisplayFormat that allows showing different
|
|
|
+ statistics along the source gate of the channel. Specifying "" as display format
|
|
|
+ results the same behavior as DatarateChannel (with no performance penalty).
|
|
|
+ If you want to gather statistics, you do not need this channel. The DatarateChannel
|
|
|
+ already emits signals "channelBusy", "messageSent" and "messageDiscarded"
|
|
|
+ that can be used to calculate different statistics. Use "opp_run -h neddecls"
|
|
|
+ to see what statistics are provided by default. e.g in INI file use
|
|
|
+ **.channel.throughput.result-recording-modes=+last to store all channel's
|
|
|
+ thoughput values as scalars.

|
+INET-1.99.0 (March 3, 2011)
|
|
|
+---------------------------
|
|
|
+
|
|
|
+This is a beta of a major feature release, with new models and also incompatible
|
|
|
+changes. If you are upgrading from an earlier INET version, expect to have
|
|
|
+to revise your existing omnetpp.ini files and possibly NED/C++ files as well.
|
|
|
+
|
|
|
+The most significant changes:
|
|
|
+
|
|
|
+- replaced cOutVector and recordScalar() with signal-based statistics
|
|
|
+ recording in most places (see @statistic properties in NED files)
|
|
|
+
|
|
|
+- support for more than one type of tcpApp and udpApp in StandardHost
|
|
|
+ (elimination of tcpAppType/udpAppType parameters)
|
|
|
+
|
|
|
+- Interfaces renamed to start with letter "I". BasicMobility -> IMobility,
|
|
|
+ TCPApp->ITCPApp, UDPApp->IUDPApp, SCTPApp->ISCTPApp, MacRelayUnit->IMacRelayUnit,
|
|
|
+ Radio->IRadio, Ieee80211Mgmt->IIeee80211Mgmt, OutputQueue->IOutputQueue,
|
|
|
+ INetworkInterface->IWiredNic
|
|
|
+
|
|
|
+- added new AdhocHost for basic node types used in adhoc networks. Supports
|
|
|
+ mobility and multiple wireless radios. It obsoletes the MFMobileHost
|
|
|
+ (use AdhocHost with **.wlan.type-name=Nic80211) and MobileHost (use AdhocHost
|
|
|
+ with default parameters)
|
|
|
+
|
|
|
+- added new AccessPoint module with configurable wireless, ethernet and relay
|
|
|
+ unit and mobility module types. Obsoletes: WirelessAP and WirelessAPWithEth
|
|
|
+ (use AccessPoint), WirelessAPSimplified and WirelessAPWithEthSimplified
|
|
|
+ (use AccessPoint with **.wlan.type-name=Ieee80211NicAPSimplified),
|
|
|
+ WirelessHost (use StandardHost with numRadios=1) and WirelessHostSimplified
|
|
|
+ (use StandardHost with numRadios=1 and **.wlan.type-name=Ieee80211NicSTASimplified)
|
|
|
+
|
|
|
+- in StandardHost and Router it is now possible to configure what wireless, ethernet, ppp
|
|
|
+ or external interfaces are used. Wired interfaces must implement IWiredNic, and wireless
|
|
|
+ modules must implement IWirelessNic. Mobility type and number of wireless cards (default=0)
|
|
|
+ can be also configured via **.wlan.type-name and **.mobility.type-name. The use of
|
|
|
+ interfaces obsoletes several older modules which differed only in interface types
|
|
|
+ (like WirelessHost or ExtRouter)
|
|
|
+
|
|
|
+- enhanced Router to support external interfaces, ppp, wireless, ethernet etc. This module
|
|
|
+ is similar to StandardHost except it does not contain the transport layer and application layer
|
|
|
+ protocols (plus IPForwarding is enabled by default). Obsoletes the ExtRouter module (use Router)
|
|
|
+
|
|
|
+- NetworkLayer and NetworkLayer6: added dummy modules that implement the IHook interface
|
|
|
+ at the bottom of network layer (above link layer). This allows one to insert
|
|
|
+ thruput metering, packet drop and duplication modules etc. without modifying the module.
|
|
|
+ New modules implementing IHook: ThruputMeter, DropsGenerator, DuplicatesGenerator and Nop.
|
|
|
+ Use **.networkLayer.outputHook.type-name = "ThruputMeter" to configure them (use inputHook
|
|
|
+ for incoming traffic)
|
|
|
+
|
|
|
+- added global ARP optimization. If you are not interested in modeling the traffic of ARP protocol,
|
|
|
+ it is now possible to use a much faster implementation by specifying (by Alfonso Ariza Quintana):
|
|
|
+ **.networkLayer.arp.globalARP=true
|
|
|
+
|
|
|
+- multiple radios (on multiple channels) are supported by StandardHost, AdhocHost
|
|
|
+ and Router if ChannelControllerExtended is used in the network.
|
|
|
+
|
|
|
+- point-to-point Ethernet links can now use normal DatarateChannels
|
|
|
+ (EtherMAC's txrate parameter was removed)
|
|
|
+
|
|
|
+- added a new TCP model that directly wraps the lwIP stack (without
|
|
|
+ NetworkSimulationCradle (NSC) overhead)
|
|
|
+
|
|
|
+- TCP transfer mode (bytecount / cPacket / bytestream) is now
|
|
|
+ controlled by the app via a control info field (the sendQueueClass/
|
|
|
+ receiveQueueClass TCP module parameters were removed); this works across
|
|
|
+ all three TCP models (native OMNeT++, NSC, lwIP)
|
|
|
+
|
|
|
+- experimental support for application-imposed TCP flow control (i.e.
|
|
|
+ implementation of "socket read" calls; this is not yet in the
|
|
|
+ "integration" branch)
|
|
|
+
|
|
|
+- brand new BGPv4 model, contributed by Helene Lageber
|
|
|
+
|
|
|
+- OSPF model: mass renaming and code formatting to make code conform
|
|
|
+ to the rest of INET in coding style
|
|
|
+
|
|
|
+- fix: Ieee80211DataFrame was missing the LLC SNAP header, so all
|
|
|
+ 802.11 data frames were simulated with 8 bytes less length than
|
|
|
+ they should have (this will slightly modify simulation results)
|
|
|
+
|
|
|
+- RTP model refactoring to make it use msg files and a control info
|
|
|
+ based interface toward apps
|
|
|
+
|
|
|
+- some improvements INETMANET implemented have been taken over into
|
|
|
+ INET (also to decrease INETMANET maintenance cost)
|
|
|
+
|
|
|
+- started taking over xMIPv6's modification to the base INET, so
|
|
|
+ xMIPv6 won't need to patch INET
|
|
|
+
|
|
|
+- added basic "New INET simulation" wizards which appear under
|
|
|
+ File|New in the IDE
|
|
|
+
|
|
|
+- started working on an INET User Manual (see inet.omnetpp.org)
|
|
|
+
|
|
|
+- added an initial test suite with tests for Ethernet, 802.11 and TCP
|
|
|
+ (uses OMNeT++'s opp_test utility and the "omnetpp" R plugin for
|
|
|
+ scripted checking of simulation results; not yet in "integration")
|
|
|
+
|
|
|
+- many smaller bug fixes and refactoring, mostly invisible for users
|
|
|
+
|
|
|
+In more details:
|
|
|
+
|
|
|
+* Reorganized StandardHost:
|
|
|
+
|
|
|
+Several changes were introduced to make the basic building blocks of
|
|
|
+simulation (StandardHost, AdhocHost, Router etc.) more configurable,
|
|
|
+without the need to copy and modify the modules or derive a new module
|
|
|
+type. Applications, tcp type, nic, mobility, routing protocols can be
|
|
|
+configured using parameters or the **.type-name=typename in the .ini file.
|
|
|
+
|
|
|
+* Ethernet point-to-point links:
|
|
|
+
|
|
|
+In the old code, datarate of Ethernet channels were to be set to zero, and
|
|
|
+the real datarate given in the txrate parameter of EtherMAC. This was to
|
|
|
+work around a limitation in OMNeT++ 3.x's channel support. In the new code,
|
|
|
+the txrate parameter is gone, and the datarate should be set on the
|
|
|
+channel. This is consistent with e.g. PPP. This requires non-backward
|
|
|
+compatible changes to models.
|
|
|
+
|
|
|
+* Support for several different TCP/UDP apps in StandardHost
|
|
|
+
|
|
|
+In the old code, tcpApp[] is declared as
|
|
|
+ tcpApp[numTcpApps]: <tcpAppType> like TCPApp;
|
|
|
+which has the side effect that when using StandardHost, all apps have to be
|
|
|
+the same type (the one in the tcpAppType parameter). OMNeT++ 4.x supports
|
|
|
+setting the types one-by-one, using the following syntax:
|
|
|
+ tcpApp[numTcpApps]: <> like TCPApp;
|
|
|
+and in the ini file, you have to write
|
|
|
+ **.tcpApp[0].type-name = "inet.applications.tcpapp.TCPBasicClientApp"
|
|
|
+ **.tcpApp[1].type-name = "inet.applications.tcpapp.TCPEchoApp"
|
|
|
+ **.tcpApp[*].type-name = "inet.applications.tcpapp.TCPSinkApp"
|
|
|
+ etc.
|
|
|
+The existing tcpAppType/udpAppType/sctpAppType parameters would be removed.
|
|
|
+However, this also means that existing ini files have to be changed.
|
|
|
+If they are not updated, the simulation will not work.
|
|
|
+
|
|
|
+* Multiple TCP implementations, and related parameterization changes
|
|
|
+
|
|
|
+INET now supports Network Simulation Cradle (NSC; wraps several FreeBSD,
|
|
|
+Linux and lwIP stacks), and we have an lwIP-based TCP module as well
|
|
|
+(without the NSC limitations and overhead); the NED types are TCP, TCP_NSC,
|
|
|
+TCP_lwip. Any of them can be selected in StandardHost, via the tcpType
|
|
|
+parameter (the tcp module is now declared as "tcp: <tcpType> like ITCP").
|
|
|
+tcpType defaults to the native OMNeT++ TCP module.
|
|
|
+
|
|
|
+The sendQueueClass/rcvQueueClass parameters are gone. They were used to
|
|
|
+select what to transmit inside TCP segments: C++ objects (cPacket) or byte
|
|
|
+counts only. Now, this can (must) be specified per-connection by the app
|
|
|
+layer, because the app knows best what it requires. Also, instead of two
|
|
|
+class names now there is a single enum value; it should be put into the
|
|
|
+dataTransferMode field of TCPOpenCommand. Potential values are:
|
|
|
+
|
|
|
+ TCP_TRANSFER_UNDEFINED = 0; // Invalid value
|
|
|
+ TCP_TRANSFER_BYTECOUNT = 1; // Transmit byte counts only
|
|
|
+ TCP_TRANSFER_OBJECT = 2; // Transmit the application packet C++ objects
|
|
|
+ TCP_TRANSFER_BYTESTREAM = 3; // Transmit actual bytes
|
|
|
+
|
|
|
+Ideally, all 3 TCP implementations should understand all 3 transfer modes;
|
|
|
+currently OBJECT support is missing from TCP_NSC.

+INET-20110225
|
|
|
+-------------
|
|
|
+
|
|
|
+- additional statistics in the SCTP module (Alberto Cortes)
|
|
|
+
|
|
|
+- fix for SCTP Path.Max.Retrans threshold problem (Alberto Cortes)
|
|
|
+
|
|
|
+- minor changes in #includes to ensure compatibility with upcoming OMNeT++ 4.2
|
|
|
+
|
|
|
+
|
|
|
+INET-20100723
|
|
|
+-------------
|
|
|
+
|
|
|
+- TCP improvement (Thomas Reschka, Zoltan Bojthe).
|
|
|
+ * implemented RFC 1323 (TCP Extensions for High Performance):
|
|
|
+ - Window Scale option
|
|
|
+ - Timestamps option (Round-Trip Time Measurement - RTTM)
|
|
|
+ - Protect Against Wrapped Sequence Numbers (PAWS)
|
|
|
+ - added a PAWS modification according to the latest proposal
|
|
|
+ of the tcplw@cray.com list (Braden 1993/04/26)
|
|
|
+ * implemented missing part of RFC 2581: Re-starting Idle Connections
|
|
|
+ * various fixes
|
|
|
+ * see details in src/transport/tcp/ChangeLog.
|
|
|
+
|
|
|
+- added examples for new TCP features (Thomas Reschka):
|
|
|
+ * examples/inet/tcptimestamps
|
|
|
+ * examples/inet/tcpwindowscale
|
|
|
+
|
|
|
+- added NetAnimTrace module (Andras Varga). This module can be used to record
|
|
|
+ input for the NetAnim program (http://www.nsnam.org/wiki/index.php/NetAnim)
|
|
|
+
|
|
|
+- Ieee80211Radio: added a shadowing component for the path loss reception model
|
|
|
+ (Nikos Simantirakis). This is a random variable has a normal distribution
|
|
|
+ in dB and results to -normal distribution in mW. This is a widespread and
|
|
|
+ common model used for reproducing shadowing effects (Rappaport, T. S. (2002),
|
|
|
+ Communications - Principles and Practice, Prentice Hall PTR).
|
|
|
+
|
|
|
+- bugfix and small improvements in SCTP, TCPSessionApp, ThruputMeter
|
|
|
+
|
|
|
+- cosmetic changes in many other files (comments, indentation, compiler warning
|
|
|
+ elimination, variable renaming, etc.)
|

|
+
|
|
|
+INET-20100323
|
|
|
+-------------
|
|
|
+
|
|
|
+- added "label" annotations to gates and modules to support the adaptive palette
|
|
|
+ filtering and gate matching in the connection chooser (OMNeT++ 4.1).
|
|
|
+
|
|
|
+- updated SCTP implementation by Michael Tuexen, Irene Ruengeler and
|
|
|
+ Thomas Dreibholz
|
|
|
+
|
|
|
+- added support for Sam Jensen's Network Simulation Cradle,
|
|
|
+ http://www.wand.net.nz/~stj2/nsc/, which makes real-world TCP stacks available
|
|
|
+ in simulations. Currently NSC supports the FreeBSD, OpenBSD, lwIP and Linux
|
|
|
+ stacks. The TCP_NSC module (transport/tcp_nsc) is a drop-in replacement for the
|
|
|
+ normal TCP module (transport/tcp), and can be activated with a single parameter
|
|
|
+ setting in StandardHost. See src/transport/tcp_nsc, 3rdparty/README, and
|
|
|
+ examples/inet/tcpclientserver.
|
|
|
+
|
|
|
+- added TCP SACK and New Reno implementation by Thomas Reschka. The original TCP
|
|
|
+ version is still available as TCP_old. See src/transport/tcp/ChangeLog for details.

+INET-20090325
|
|
|
+-------------
|
|
|
+
|
|
|
+- tagged version for OMNeT++ 4.0 final
|
|
|
+- reworked build system to create shared library by default
|
|
|
+- added SCTP from Michael Tuexen and Irene Ruengeler
|
|

|
+INET-20080920
|
|
|
+-------------
|
|
|
+
|
|
|
+Internal snapshot, for omnetpp-4.0b6.
|
|
|
+
|
|
|
+- performance optimization in all queue modules: remember output gate pointer
|
|
|
+ instead of looking up gate by name for each send()
|
|
|
+
|
|
|
+- Ieee80211AgentSTA.cc: randomize the start time of the scanning process.
|
|
|
+ (Randomizing the time of sending the first beacon in Ieee80211MgmtAP.cc
|
|
|
+ was already done earlier.)
|
|
|
+
|
|
|
+- IP: set TTL to 1 on new datagram if the destination address is link local
|
|
|
+ multicast, to prevent broadcasting to non-neighbouring routers.
|
|
|
+
|
|
|
+- several bugfixes
|
|
|
+
|
|
|
+
|
|
|
+INET-20080709
|
|
|
+-------------
|
|
|
+
|
|
|
+Internal snapshot, for omnetpp-4.0b3.
|
|
|
+
|
|
|
+- interface table and routing table are now accessed via the C++ interfaces
|
|
|
+ IInterfaceTable and IRoutingTable. This is done to reduce interdependencies
|
|
|
+ among modules; more specifically, to allow users implement their own
|
|
|
+ InterfaceTables and RoutingTables and plug them into INET simulations,
|
|
|
+ without any change to the base INET.
|
|
|
+
|
|
|
+- PPP and EtherMAC2: performance: don't fire tx begin/end notifications if
|
|
|
+ no one is listening; remember output gate pointer instead of looking it up
|
|
|
+ by name for each send
|
|
|
+
|
|
|
+- UDPEchoApp: messageLength parameter now understood in bytes not bits
|
|
|
+
|
|
|
+- RoutingTable: implemented routing cache and other optimizations
|
|
|
+
|
|
|
+
|
|
|
+INET-20080630
|
|
|
+-------------
|
|
|
+
|
|
|
+Internal snapshot, for omnetpp-4.0b2.
|
|
|
+
|
|
|
+- to enable and encourage extending INET via subclassing (as opposed to
|
|
|
+ patching), nearly all member functions made virtual (except in data classes
|
|
|
+ like IPAddress), and also, private sections in most classes were changed to
|
|
|
+ protected.
|
|
|
+
|
|
|
+- some refactoring on TCP, UDP and IP, to allow subclassing of TCP, UDP and IP
|
|
|
+ packets: packets are now created via factory methods that can be overridden
|
|
|
+ if needed
|
|
|
+
|
|
|
+- AbstractQueue (base class for IP and other modules) made more efficient: now it
|
|
|
+ doesn't schedule a timer if (when) serviceTime is zero.
|
|
|
+
|
|
|
+- IPAddress class made more efficient [code from Ingmar Baumgart, OverSim]
|
|
|
+
|
|
|
+- parsim: added pack/unpack functions for IPAddress, IPv6Address, IPvXAddress
|
|
|
+
|
|
|
+- InterfaceTable: added deleteInterface(). This also causes RoutingTable to
|
|
|
+ drop routes that correspond to the deleted interface.
|
|
|
+
|
|
|
+- RoutingTable: wrapped naked data members of IPRoute into getters/setters;
|
|
|
+ enforce by returning "const" pointers that routes already added cannot be
|
|
|
+ changed any more (one must delete and re-add it)
|
|
|
+
|
|
|
+- InterfaceTable: created a getInterfaceById() method, NOT to be
|
|
|
+ confused with getInterface(pos)! Ids are stable after deletions,
|
|
|
+ unlike 0..getNumInterfaces()-1 indices, and reliable/safe unlike
|
|
|
+ InterfaceEntry* pointers
|
|
|
+
|
|
|
+- InterfaceTable and RoutingTable now fire proper notifications on changes:
|
|
|
+ NF_INTERFACE_CREATED, NF_INTERFACE_DELETED, NF_INTERFACE_STATE_CHANGED,
|
|
|
+ NF_INTERFACE_CONFIG_CHANGED; NF_IPv4_ROUTE_ADDED, NF_IPv4_ROUTE_DELETED,
|
|
|
+ NF_IPv6_ROUTE_ADDED, NF_IPv6_ROUTE_DELETED, etc.
|
|
|
+
|
|
|
+- NotificationBoard: added hasSubscribers(int category) method, to allow for
|
|
|
+ optimizing out firing change notifications if there's no one listening.

+INET-20080624
|
|
|
+-------------
|
|
|
+
|
|
|
+Internal snapshot, for omnetpp-4.0b2.
|
|
|
+
|
|
|
+- updated for OMNeT++ 4.0b2
|
|
|
+
|
|
|
+- extensive renaming: added "get" verb to getter methods in most classes;
|
|
|
+ also eliminated @addGetVerb(true) from message classes
|
|
|
+
|
|
|
+- revived the RTP model: starting from Ahmed Ayadi's patch, migrated the code
|
|
|
+ to OMNeT++ 4.0, and started some refactoring (started introducing .msg files
|
|
|
+ for handcoded message classes; not yet finished)
|
|
|
+
|
|
|
+
|
|
|
+INET-20080606
|
|
|
+-------------
|
|
|
+
|
|
|
+Internal snapshot, for omnetpp-4.0b1.
|
|
|
+
|
|
|
+- directory structure reorganized
|
|
|
+
|
|
|
+- converted to OMNeT++ 4.0
|
|
|
+
|
|
|
+- some refactoring (parameter/gate name changes, etc)
|
|
|
+
|
|
|
+- IP/IPv6: do not schedule a timer if processing time is zero (change made
|
|
|
+ in base/AbstractQueue)
|
|
|
+
|
|
|
+- FlatNetworkConfigurator: use @node() property to determine which modules are
|
|
|
+ network nodes (removed moduleTypes, nonIPModuleTypes parameters)
|
|
|
+
|
|
|
+
|
|
|
+INET-20061020
|
|
|
+-------------
|
|
|
+
|
|
|
+- new example network: Examples/Ethernet/ARPTest (old ARPTest renamed)
|
|
|
+
|
|
|
+- bugfixes: AbstractRadio (Dave Symonds); Ieee80211 (also reported by Dave)
|
|
|
+
|
|
|
+
|
|
|
+INET-20060912a
|
|
|
+--------------
|
|
|
+
|
|
|
+- improvements on the wireless infrastructure: support for multiple channels
|
|
|
+ and channel switching by NICs; account for finite radio wave propagation speed
|
|
|
+
|
|
|
+- added new 802.11 model which also supports infrastructure mode; see
|
|
|
+ NetworkInterfaces/Ieee80211. Even for ad-hoc mode, Ieee80211Mac is recommended
|
|
|
+ over the older Mac80211 from MF.
|
|
|
+
|
|
|
+- added Ieee80211Radio which supersedes SnrEval80211 and Decider80211.
|
|
|
+
|
|
|
+- added EtherDuplexMAC, a simplified Ethernet implementation for full duplex
|
|
|
+ point-to-point operation mode when CSMA/CD is not in use.
|
|
|
+
|
|
|
+- makefiles within Examples/ have been largely unnecessary because all
|
|
|
+ simulations just invoke bin/INET. Realizing these makefiles have been
|
|
|
+ confusing to many people, they got removed now. The target to generate
|
|
|
+ them is still present in makemakefiles in case someone needs it.
|
|
|
+
|
|
|
+- several other fixes
|
|
|
+
|
|
|
+
|
|
|
+INET-20060330
|
|
|
+-------------
|
|
|
+
|
|
|
+- checked in the new MPLS, RSVP-TE and LDP models, written/rewritten by
|
|
|
+ Vojta Janota
|
|
|
+
|
|
|
+- new model: Network/Quagga. This is port of the Quagga routing daemon to the
|
|
|
+ INET Framework. Currently provides RIP and OSPFv2 routing. Quagga itself is
|
|
|
+ a fork of Zebra. (Ported to INET by Vojta Janota)
|
|
|
+
|
|
|
+- new model: Network/OSPFv2. This is a new OSPF implementation.
|
|
|
+ (author: Andras Babos)
|
|
|
+
|
|
|
+- UDP rewritten: similarly to TCP, dispatching is now done inside UDP, and
|
|
|
+ apps now identify sockets with a sockId; implemented ephemeral port reuse
|
|
|
+
|
|
|
+- UDPSocket class added to facilitate talking to the UDP model from apps;
|
|
|
+ analogous to TCPSocket (thanks to Michael Tuexen and Vojta Janota for
|
|
|
+ feedback)
|
|
|
+
|
|
|
+- new snapshot of the IPv6 module (by Wei Yang Ng)
|
|
|
+
|
|
|
+- added ability to write nam traces (Util/NAMTraceWriter, World/NAMTrace);
|
|
|
+ feature originally implemented by Vojta Janota (and refactored by Andras,
|
|
|
+ so bugs are very likely mine)
|
|
|
+
|
|
|
+- implemented ThruputMeteringChannel which can display #packets, pk/sec etc
|
|
|
+ on the links; and ChannelInstaller as a temporary solution to install
|
|
|
+ ThruputMeteringChannel instead of the built-in BasicChannel class.
|
|
|
+
|
|
|
+- updated module class ctors/dtors for OMNeT++ 3.2; changed msg->length()/8 to
|
|
|
+ msg->byteLength() and msg->setLength(8*bytes) to msg->setByteLength(bytes),
|
|
|
+ etc.
|
|
|
+
|
|
|
+- TCP: Reno bugs fixed (reported by Pascal Rousseau); TCPMessageBasedSendQueue
|
|
|
+ seqNo bug fixed (Adam Hudson); implemented reuse of ephemeral ports;
|
|
|
+ fixed incorrect behaviour when ACK of SYN carries data (reported by Joachim
|
|
|
+ Meichle); fixed minor issue that when the user issued CLOSE, transition to
|
|
|
+ FIN_WAIT_1 was done immediately and not deferred until all data are sent.
|
|
|
+
|
|
|
+- added Applications/TCPApp/TCPSpoof
|
|
|
+
|
|
|
+- hosts have now the same queues as routers (reported by Michael Tuexen)
|
|
|
+
|
|
|
+- ev replaced with EV in every module (speed increase in Express mode)
|
|
|
+
|
|
|
+- NetworkLayer(6): gates towards interfaces renamed to ifOut[]/ifIn[]
|
|
|
+
|
|
|
+- FlatNetworkConfigurator internals refactored
|
|
|
+
|
|
|
+- added another network configurator, NetworkConfigurator
|
|
|
+
|
|
|
+- RoutingTable: routerId selection moved from stage 1 to stage 3 (you may
|
|
|
+ need to revise your code if it depends on routerId)
|
|
|
+
|
|
|
+
|
|
|
+INET-20050922
|
|
|
+-------------
|
|
|
+- patched for OMNeT++ 3.2:
|
|
|
+ - added '=NULL' default value to all args of hand-code module constructors
|
|
|
+ (2 or 3 places)
|
|
|
+ - RSVPPacket.h: dup() return type has to be cPolymorphic with OMNeT++ 3.2;
|
|
|
+ fixed it using '#if OMNETPP_VERSION<0x0302...#else...#endif'
|
|
|
+
|
|
|
+ Note: THIS IS THE ONLY RELEASE WHICH IS COMPATIBLE WITH BOTH 3.1 AND 3.2
|
|
|
+
|
|
|
+- UDP dispatchByPort bug fixed; further smaller fixes
|
|
|
+
|
|
|
+- IPv6 updated (still unfinished)
|
|
|
+
|
|
|
+- NOT YET FIXED:
|
|
|
+ - TCP bug http://www.omnetpp.org/listarchive/msg05687.php
|
|
|
+ - incorrect handling of host queues (Michael Tuexen)
|
|
|
+
|
|
|
+
|
|
|
+INET-20050720
|
|
|
+-------------
|
|
|
+
|
|
|
+- module types renamed for consistency: PPPModule -> PPP, TCPMain -> TCP,
|
|
|
+ UDPProcessing -> UDP
|
|
|
+
|
|
|
+- C++ methods renamed: isNull() -> isUnspecified() in IPAddress, IPv6Addres,
|
|
|
+ IPvXAddress
|
|
|
+
|
|
|
+- created two subdirs under Transport/TCP: flavours and queues, and moved
|
|
|
+ the appropriate cc/h files there. The structure of the TCP model should
|
|
|
+ now be much more obvious to readers. Also added READMEs explaining things.
|
|
|
+
|
|
|
+- TCP fixes: raise an error (~EADDRINUSE) on attempt to create more than one
|
|
|
+ connections to listen on the same port
|
|
|
+
|
|
|
+- implemented REDQueue
|
|
|
+
|
|
|
+- beginnings of a "Getting started with TCP" doc
|
|
|
+
|
|
|
+
|
|
|
+INET-20050705
|
|
|
+-------------
|
|
|
+- TCP improvements: separate congestion control behaviour classes
|
|
|
+ TCPTahoe, TCPReno and TCPNoCongestionControl provided, for teaching
|
|
|
+ purposes (their code is very short, to the point, and extensively
|
|
|
+ commented).
|
|
|
+
|
|
|
+- TCP: fixed bogus RTT calculation and other other bugs; also, sequence
|
|
|
+ numbers are now recorded into omnetpp.vec, so with Plove one can create
|
|
|
+ sequence number plots like Sally Floyd's [thanks to Ahmet Sekercioglu
|
|
|
+ for help!]
|
|
|
+
|
|
|
+- still TCP: fixed the bug which caused closing of a connection to be reported
|
|
|
+ 2MSL (240s) later to the user.
|
|
|
+
|
|
|
+- Added support for drop-tail router queues, and queues with QoS support
|
|
|
+ based on DS Code Point; RED in preparation (see Network/Queue)
|
|
|
+
|
|
|
+- Added wireless and mobility support (based on Mobility Framework code),
|
|
|
+ including 802.11b ad-hoc mode MAC, and several new mobility models
|
|
|
+ (also new to MF). Supports mobility traces from BonnMotion and ANSim.
|
|
|
+
|
|
|
+- Contract directories introduced: Transport/Contract, Network/Contract
|
|
|
+ and NetworkInterfaces/Contract. These directories contain a minimal set
|
|
|
+ of classes necessary for using one layer's functionality from higher layers.
|
|
|
+
|
|
|
+- Added notification mechanism: modules can now notify each other about
|
|
|
+ "events" such as routing table changes, interface status changes (up/down),
|
|
|
+ interface configuration changes, wireless handovers, changes in the state
|
|
|
+ of the wireless channel, mobile node position changes, etc. Notification
|
|
|
+ works via the NotificationBoard which replaces the Blackboard.
|
|
|
+
|
|
|
+- InterfaceTable introduced: it stores all interface configuration that was
|
|
|
+ previously stored in RoutingTable. Per-interface data structure was also
|
|
|
+ split into protocol independent (InterfaceEntry) and protocol dependent
|
|
|
+ (IPv4InterfaceData, IPv6InterfaceData) parts.
|
|
|
+
|
|
|
+- ScenarioManager introduced (experimental, in World/ subdirectory):
|
|
|
+ it addresses the need for simulating scenarios like "what if this cable
|
|
|
+ breaks at t=20s", or "what if traffic intensity grows at t=100s".
|
|
|
+ Scenario is described in an XML file.
|
|
|
+
|
|
|
+- Ping and VideoStream applications added (from IPv6SuiteWithINET)
|
|
|
+
|
|
|
+- ARP got moved up from L2 to L3; this is to prepare for IPv6 support (IPv6
|
|
|
+ doesn't need ARP, so we can no longer have it as part of the network
|
|
|
+ interfaces)
|
|
|
+
|
|
|
+- prepared for IPv6: application layer, transport layer and IPv6 contract
|
|
|
+ taken over from IPv6SuiteWithINET-20050502
|
|
|
+
|
|
|
+- work in progress: from-scratch IPv6 implementation by Wei Yang Ng (Monash
|
|
|
+ University) and Andras Varga
|
|
|
+
|
|
|
+- added INET_API definitions to classes, so that one can build a DLL that can
|
|
|
+ be loaded dynamically into INET.exe (hint: compile DLL code *without*
|
|
|
+ /DBUILDING_INET, and link them with INET.lib! then add [General]/load-libs=
|
|
|
+ to omnetpp.ini.)
|
|
|
+
|
|
|
+- Network/IPv4d subdirectory finally thrown out. It was a bad idea to
|
|
|
+ implement IP with a dozen small modules in the first place.
|
|
|
+
|
|
|
+- added files called !WORK_IN_PROGRESS! with some explanations to
|
|
|
+ directories which contain unfinished simulation models.
|
|
|
+
|
|
|
+
|
|
|

+---------------------------------------------------
|
|
|
+2004-02-04 Andras Varga
|
|
|
+
|
|
|
+ * got it compiled with omnetpp-3.0pre1. changes:
|
|
|
+ - added #include <iostream>, using std::ostream at a couple of places
|
|
|
+ - deprecated receiveOn(), receiveNewOn() no longer exists, replaced by:
|
|
|
+ msg = receive();
|
|
|
+ ASSERT(dfmsg->arrivedOn("fromEnqHook")); // FIXME revise this
|
|
|
+ * removed ProcessorManager altogether
|
|
|
+
|
|
|
+2003-09-19 Andras Varga
|
|
|
+
|
|
|
+ * added the MPLS/LDP/RSVP-TE models created by Xuan Thang Nguyen
|
|
|
+ (Xuan.T.Nguyen@uts.edu.au) at UTS (University of Technology, Sydney).
|
|
|
+ See http://charlie.it.uts.edu.au/~tkaphan/xtn/capstone/
|
|
|
+
|
|
|
+ * did IPsuite modifications necessary fo MPLS. Modularity is preserved:
|
|
|
+ it is still possible to build IPSuite without the MPLS models.
|
|
|
+
|
|
|
+2003-09-18 Andras Varga
|
|
|
+
|
|
|
+ * merged patches for compiling with MSVC.
|
|
|
+
|
|
|
+ * module descriptions (comments) added to/rearranged in all NED files
|
|
|
+ for documentation generation with new opp_neddoc.
|
|
|
+
|
|
|
+ * DIRECTORY STRUCTURE WAS REARRANGED along the lines of the OSI layers,
|
|
|
+ and also to make it consistent with the IPv6Suite. Hopefully every file
|
|
|
+ is now where one would expect to find it.
|
|
|
+
|
|
|
+ * added makemake.cmd for generating Makefile.vc's (using opp_nmakemake)
|
|
|
+ for building with MSVC, and makemake for generating Unix makefiles
|
|
|
+
|
|
|
+ * lots of minor fixes to make the code compile with MSVC.
|
|
|
+ Note: for compatibility with MSVC6.0,
|
|
|
+ 1. return type of dup() should ALWAYS be cObject* (and cannot be the
|
|
|
+ actual class name)
|
|
|
+ 2. class variables cannot be initialized (even const or
|
|
|
+ static const ones) within the class declaration.
|
|
|
+
|
|
|
+ * updated for recent OMNeT++ versions: added ",row" to vector module
|
|
|
+ display strings; removed className() methods, etc.
|
|
|
+
|
|
|
+ * FIXME: KIDSRouter was missing from the original IPSuite! KIDSNw1
|
|
|
+ didn't compile. I temporarily substituted a copy of NextHopRouter.
|
|
|
+
|
|
|
+2003-09-17 Andras Varga
|
|
|
+
|
|
|
+ * taken ipsuite-20021124-src.tgz and started improving it.

|
|
+

|
+IPSuite's change log, 2000-2001
|
|
|
+-------------------------------
|
|
|
+Before Andras Varga took over the development in 2003, IPSuite was
|
|
|
+created and developed at University of Karlsruhe, Germany.

|
|
|
+2001-12-10 Ulrich Kaage <kaage@int.uni-karlsruhe.de>
|
|

|
|
|
+ copy constructor -> const argument
|
|
|
+ virtual long length(const ) -> virtual long length(const) const
|
|
|
+ virtual int numInitStages() -> virtual int numInitStages () const

|
|
|
+ implementation of TCP flavours Reno (fast recovery) and New Reno.
|
|
|
+
|
|
|
+2001-03-19 Verena Kahmann <kahmann@telematik.informatik.uni-karlsruhe.de>
|
|
|
+ * deleted all queues and behaviors except FIFO* and the basic behaviors.
|
|
|
+ Maybe we have to apply some extra cleaning still.
|
|
|
+2000-12-19 Ulrich Kaage <kaage@int.uni-karlsruhe.de>
|
|
|
+
|
|
|
+ * recent (standalone) TCP model is merged into the ip-suite. The
|
|
|
+ simple test network is now located in ./Networks/TCPTester
