package inet.common.queue;

//
// This module implements weighted round-robin scheduling.
//
// There is a weight associated with each input gate.
// Initially each input gate gets as many tokens as their
// weight. When a packet is requested then the first input
// gate is selected that has a packet and enough tokens,
// and one token is consumed. When there are waiting input
// packets, but there is no enough tokens to schedule one,
// then each token bucket is filled up.
//
// This module implements the IPassiveQueue C++ interface,
// therefore it can be used as the queue component of a NIC,
// and as the input of another scheduler.
