摘要

提出以一种基于帧传输效率的MAC层拥塞通告机制

当中间节点检测到帧传输效率小于某一阈值时

通过ECN通告使发送方主动降低发送速率。该机制只需在链路层完成

不需改变现有的传输层协议。仿真结果表明该方法能较大地提高网络的效率

尤其在多流情况下比原有的TCP协议的吞吐量提高了50%左右

同时能够保证多流之间的公平性。

Abstract

A MAC layer congestion notification scheme was proposed by using frame transmission utility.The TCP sender would reduce the congestion window based on ECN when forwarding nodes detect that the frame transmission utility was smaller than the threshold.This congestion control mechanism was realized only at the link layer and need not modify the existing transport protocol.The simulation results show that this scheme can effectively improve the network efficiency

especially in the case of multi TCP flows.The TCP throughput is increased by 50% and the fairness is satisfactory in the mean time.
