Abstract :
TCP congestion control technology is one of the research topics of IP QoS. IETF proposed the deployment of active queue management in routers and recommended the RED algorithm. This paper analyses the insufficiency of the transmitting of RED congestion notification and presents an early explicit congestion notification algorithm. The new algorithm ensures that the congestion notification can reach the TCP source as quickly as it can, in answer to the early congestion of routers. Some experiments are given in the paper using a modified NS simulator. The experiments show that the algorithm is better than RED in reducing the packet loss rate besides guaranteeing the router throughput
