摘要

提出了一种在城域以太网节点设备中基于抖动检测的拥塞控制算法(JDCC算法)。通过检测和丢弃那些时延抖动值超过用户容忍门限值的数据分组

给正常的数据分组提供了更高的带宽

提高了实时多媒体流在城域以太网中传输的服务质量。实验结果表明JDCC算法可以更有效地降低实时多媒体流的平均时延抖动

且能提高有效吞吐量。

Abstract

A novel congestion control algorithm （JDCC） for multimedia traffics was proposed. JDCC 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.
