Abstract

We propose an algorithm to realize proportional bandwidth allocation in DiffServ networks. According to the feedback information, ingress routers adjust Committed Information Rates (CIRs) of different aggregates using AIMD way to let the network reach an exactly subscribed state. Based on CIRs, packets are marked. Simulations with ns2 show that proportional bandwidth allocation under different network conditions can be achieved.
