Performance and Evaluation of Congestion Control and Routing Algorithm for Improving Internet Traffic Control System

摘要

With the development of multiple services in internet, the dominant internet congestion control scheme namely the TCP, end to end control[6] becomes insufficient. The RED algorithm to detect inefficient congestion early and to convey congestion notification to the end host, in order to allow them. To reduce their transmission rate before queue overflow and packet loss occur using active queue management[5]. Online mechanism for adaptively changing the parameters according to the observed traffic. This algorithm called adaptive RED. This paper also presents completely different architecture , which avoids congestion control[1][2] to prevent packet loss and regulate irrespective traffic in a uniform fashion. No peer flow state information is maintained in route while the fairness is guaranteed. The new architecture takes a node to node approach advocating close coordination among the core router , the edge router and the host. Employing both router and host mechanism, it has 3 main elements, the generic congestion control protocol(GCCP), the early congestion detector and the rate controller. The revised version of RED, called GCCP capable RED. Router and host shows it advantages over pure end to end control. This paper presents one specific algorithm for tolerating RED parameters to the input traffic.
