摘　　要：TCP吞吐量模型的研究是网络协议研究的一个重要方面 ,同一些其它模型相比 ,Padhye提出的TCP吞吐量模型比较精确地描述了TCP吞吐量与往返时间、丢包率和超时时限的关系 ,但在丢包率很高的场合 ,Padhye模型误差较大 ,本文分析了高网络负荷下TCP传输的性能 ,提出了一个高网络负荷下TCP吞吐量的改进Padhye模型 ,实验表明 ,该模型在高网络负荷环境下更接近实际情况 .Research on TCP throughput model is an important aspect of research on network protocols.Compared with some other models,the model given by Padhye is more accurate to describe the relation between TCP throughput and round trip time,rate of packet loss,and time out limit.But under heavy network load,Padhye model doesn't match the results very well.In this paper,the performance of TCP under heavy network load is analyzed,and a Padhye Model based TCP throughput model in heavy network load is given forth.The experiment indicates that this model matches the results better than Padhye model in heavy network load.
