基于仿真的TCP流量控制机制的研究

Simulation-based Study on TCP Flow Control Mechanisms

文章介绍了TCP协议对流量控制的一些重要机制:慢启动,拥塞避免,快速重传,快速恢复等;然后通过仿真这些根据不同机制不同算法的TCP版本,比较不同网络条件下的版本在性能上的差异,从而直观的演示了流量控制机制的正负效果;最后给出一个更改TCP SACK初始化窗口大小值的仿真实验,通过仿真予以验证分析。

Some important flow control mechanisms of TCP protocol are introduced, such as Slow Start, Congestion Avoidance, Fast Retransmit and Fast Recovery. By simulating various Tcp flavors. We get to knowing the different performance in different conditions and directly demonstrate positive and negative effect. Finally, a simulation for amended SACK with increasing Initial Window Size has been run with OPNET in order to validate the foregoing estimated result.
