Abstract
Congestion control is an important part of IP QoS. The traditional congestion control algorithms judge the network congestion status and make drop decisions mainly according to the congestion information of local buffer resources. This causes the bandwidth-wasting problem when data flow congested. The paper analyzes the problem theoretically and proposes a new congestion control algorithm (CC-AMR) based on awareness of the congestion status of multistage resources. CC-AMR accounts the congestion status of resources in remote forward engines and their ports synthetically so that more reasonable congestion control decisions can be made. The CC-AMR has been implemented and tested on a core router which is implemented basing on network processor. Results show that this algorithm can enhance the total throughput of router effectively during periods of congestion.
