摘要

本文对无线ATM网络环境下的TCP性能进行了分析.首先,对TCP的吞吐量效率进行了理论分析,并根据广域网流量分布的特点,选取几个典型的TCP报文段长,得到了TCP吞吐量效率与误信元率的关系.然后,通过在OPNET平台上进行仿真,证明了理论分析的合理性,并得出了结论.进一步地,对TCP最佳报文段长与误信元率的关系进行了分析,提出应根据误信元率情况调整传输控制协议报文段长,从而获得最大的吞吐量效率.

Abstract

TCP performance in wireless ATM networks is analyzed in this paper.The throughput efficiency formula is induced and the throughput efficiency-CER relationship is demonstrated for several TCP segment length according to the characteristics of wide area networks traffic distribution.By simulations on OPNET,the theoretical analysis is proved to be reasonable and some conclusions are drawn.Furthermore,the optimal TCP segment length is analyzed.Then it is presented that TCP segment value should be adjusted according to CER in order to get the best throughput efficiency.
