Router Buffer Traffic Load Calculation based on a TCP Congestion Control Algorithm
Kulvinder Singh · 2012
In this paper, instead of using the length of queue as a measure of congestion, we use traffic load, defined as the ratio of incoming rate over the outgoing rate at our router. The shape of packet marking probability used is similar to the one of RED, but the intuition of design is that using the traffic load information, will make the queue lesser oscillatory and thus increases the router’s throughput compared to RED. The objectives are then to bring the values of traffic load to one and to keep a nearly empty queue length in the memory buffer, so that the queuing delay is as small as possible. However the idea of the design is heuristic, as in RED. In the stability analysis, we perform here is meant to justify its use and to give guidelines for the design of the parameters. We assume that the network configuration where sources implements the TCP protocol.
