摘　　要：现有的TCP Reno在高速网络环境下存在的带宽利用率等问题,从而引出了诸如HS-TCP,S-TCP和Fast-TCP等改进的TCP拥塞控制算法。本文简单介绍三种算法,对比分析了它们存在的问题和造成的原因,并提出了可能的研究方向和目前最新的改进算法。To solve the problems of TCP Reno in the high-speed network environment, like bandwidth utilization and so on, many improved congestion control protocols such as HS-TCP, S-TCP and FAST TCP, have been put forward. In this paper, we briefly introduce three algorithms, analyze comparatively their existing problems and reasons, and also propose some possible research direction and the latest improved algorithm.
