高速网络中TCP拥塞控制端算法研究

Research of TCP Congestion Control in High Speed Networks

针对TCP在高速网络中缺陷,提出了改进的CUBIC TCP拥塞控制算法。优化算法通过监控链路缓存的变化来调整乘法减因子,达到降低网络拥塞频率和避免因高速数据流导致缓存区溢出的目的。实验结果表明优化算法的性能在高速网络中得到了较大的提高。

This paper advances CUBIC TCP to solve the problem that TCP faced in fast long-distance networks. The algorithm adjusts window decrease factor by monitoring the change of bottleneck buffer to decrease the congestion of rate of network and avoid buffer overflow caused by high speed data flow. The experiment results show that the new algorithm works well in the fast long-distance networks.
