一种自适应比例系数的TCP拥塞控制策略

An adaptive ratio strategy of TCP congestion control

互联网业务的快速发展使得网络拥塞日益严重,因此如何减轻网络拥塞也就成为当前研究的热点。针对这一问题,首先叙述了TCP拥塞控制的基本原理及其相关算法;然后对拥塞控制算法进行了详细分析并提出了自适应比例系数的新策略;最后对新策略进行NS2仿真。仿真结果表明,新方法提高了包投递率,降低了端到端时延。

With the rapid development of Internet,the problem of network congestion is becoming more and more serious.Therefore,how to lighten network congestion grows gradually the hotspot at present.To solve this trouble,in this paper,the basic principle of TCP congestion control as well as related algorithm is stated and then,some of the algorithm is improved because of it＇s faults after being analysised.Finally,we simulate the new method and it＇s result shows that the new strategy not only increases the delivery rate of packets but also reduces the end-to-end delay.
