Abstract:

A significant amount of today＇ s Interact traffic, including WWW （HTTP）, file transfer （FTP）, and ernail （SMTP） traffic, is carried out by the TCP transport protocol Analytically characterizing the throughput of TCP＇s congestion control mechanism is a very important research effort for examiniing the performance of the various aspects of TCP. At the same time, the TCP throughput model has several important applications such as the y rate control and the AQM parameter setting. The paper summarizes two TCP models and their applications. Through these applications, it is clear that t he TCP model is a very useful tool for designing and analyzing congestion control systems.

Key words:  （TCP, congestion control, throughput model, applications）
