摘　　要：首先探讨了网络拥塞出现的原因,然后分析了TCP拥塞控制的原理及四个TCP拥塞控制算法的性能,接着着重论述了TCP拥塞控制所面临的问题和对应算法的改进,最后提出了其进一步的研究方向。Firstly, the reasons of congestion in network are introduced in this paper. Then, the principle of congestion control is analyzed and the performances of four algorithms concerning TCP congestion control are evaluated. At the same time, the current essential difficulties of congestion control of TCP congestion and the corresponding improved algorithms to it, such as Tahoc, Reno, Sack, and Vegas, are presented in detail. Finally, the research directions on TCP/IP congestion control in the future are also orooosed in this oaner.
