Congestion control in cable network transmission using novel RED algorithm

Abstract

Congestion is an important issue in cable network where transmitted packets to the network are much more than holding capacity of network. Each network needs the maximum number of successful packets to reach the destination with less number of packet losses and low time delay with better fairness. There are several congestion control algorithms which have been studied to keep the network stable. They employ various techniques from which the buffer or queue management used by the router is one significant issue to control congestion. The Active Queue Management algorithms like RED controls the queue size by dropping or marking the packets before buffer becomes full. In this paper a new algorithm has been proposed and the results are compared with existing RED algorithm using network simulator (NS-2) in a responsive environment of the cable network.
