Abstract
In this paper, a novel congestion control for multimedia traffics in Metro Ethernet Networks known as Jitter-Based Congestion Control (JBCC) is proposed. The basic ideal of JBCC is that the jitter-corrupted multimedia packets are useless to the client and it is a waste of network resources to continue to forward these packets in the networks. JBCC improves the QoS of multimedia stream in Metro Ethernet Network by detecting and discarding packets that accumulated enough jitter so as to maintain a high bandwidth for packets that stay within the multimedia stream's jitter tolerance. Simulation results have shown that the proposed scheme can effectively lower the average received packet jitter than that using traditional congestion control algorithm RED and DropTail. Moreover, the proposed scheme can improve the useful goodput of the received packets when compared to RED and DropTail.
