摘要
随着网络技术的发展,网络拥塞日益严重。而TCP拥塞控制对如何解决网络拥塞问题,提高网络资源至关重要。文章首先对NewReno、Sack和Vegas拥塞算法从改进策略、延时、网络利用率、应用范围等进行了理论分析。接着通过NS仿真的方法,从拥塞窗口,吞吐量来分析具体分析它们的性能,最后比较这几种算法的优缺点及适用性。
With the development of network technology, network congestion is getting worse. The TCP congestion control is essential to solve network congestion problems and improve the network resources. Firstly theoretical analysis of congestion algorithms on NewReno, Sack and Vegas are carried out from the improvement strategy, delay, network utilization, application etc. Then, the NS simulation method is applied to analyze the specific analysis of their performance from the congestion window, throughput. At last, the advantages and disadvantages and applicability of several algorithms is obtained.
