  Abstract

As the multimedia application traffic takes more portion in the internet traffic, it is necessary to control the network congestion through the congestion control protocol In addition, the QoS-enabled networks such as DiffServ become an indispensable technology when running the multimedia applications. However, the previously proposed end-to-end congestion control algorithms take the round trip time to react the network congestion Thus, as the RTT becomes larger, the reaction against the congestion gets delayed further, while the network congestion gets worse. In addition the performance of end-to-end congestion control algorithm is degraded If the QoS-enabled network runs the congestion control mechanism in the network level without any coordination between them. In this paper. we propose the early rate adaptation protocol for the DiffServ network, which effectively links the congestion control algorithm at the host and the congestion mechanism in the network together By taking advantage of early congestion notification from the network, it is possible to react the network congestion more quickly and effectively.
