Improvement and Research on Congestion Control Algorithm of TCP Vegas
摘要
网络拥塞已经成为制约因特网发展的瓶颈.在众多TCP拥塞控制算法中
TCP Vegas表现出比其他算法更为优越的性能
但是在特定环境下也存在不足.本文通过对网络拥塞策略的研究和Vegas性能的分析
验证了Vegas整体性能优于Reno的结论
并通过分析Vegas的特点
针对α和β的值对公平性的影响
提出了一种在TCP Vegas与TCP Reno共存环境下获得良好拥塞控制的方法
并通过网络仿真证明了本方法的有效性和正确性.
Abstract
Network congestion has become a bottleneck restricting the development of the Internet.Among the TCP congestion control algorithm
TCP Vegas shows more than the other algorithms superior performance.However
in certain circumstances there are disadvantages.Based on the strategy of network congestion and Vegas performance analysis
validation of the overall performance is better than Reno’s conclusion.By analyzing the characteristics of Vegas for the α and β value on the fairness of this paper
