  1. This directory contains a simple demonstration of Diffserv QoS capabilities.
    2. 

  2. 

  3. The network contains a router with an 10Mbps Ethernet interface and a
    4. 

  4. 128kbps dialup link to a server. Clients are configured to generate
    5. 

  5. high traffic, that causes congestion at the router PPP interface.
    6. 

  6. One of the clients sends VoIP packets to the server.
    7. 

  7. 

  8. With the VoIP_WithoutQoS configuration, the queue in the router PPP interface
    9. 

  9. will be overloaded and packets are dropped randomly.
    10. 

  10. 

  11. With the VoIP_WithPolicing configuration, the VoIP traffic is classified as EF
    12. 

  12. traffic and the necessary bandwidth is allocated for it. The traffic conditioning
    13. 

  13. is configured so, that packets generated by the other clients are dropped if they
    14. 

  14. exceed the enabled rate.
    15. 

  15. 

  16. With the VoIP_WithPolicingAndQueuing configuration, the VoIP traffic is classified as EF
    17. 

  17. traffic and the necessary bandwidth is allocated for it. The router's queue is configured
    18. 

  18. so that EF packets are prioritized over other packets, so lower delays are expected.
    19. 

  19. 

  20. After running these configuration you can see the statistics by opening the
    21. 

  21. VoIP.anf file, or can hear the difference by comparing the recorded .wav files
    22. 

  22. in the results directory.
