An overview of TCP congestion control techniques

Yongmin Liu

Abstract

Firstly,the reasons of congestion in network are introduced in this paper.Then,the principle of congestion control is analyzed and the performances of four algorithms concerning TCP congestion control are evaluated.At the same time,the current essential difficulties of congestion control of TCP congestion and the corresponding improved algorithms to it,such as Tahoc,Reno,Sack,and Vegas,are presented in detail.(Finally),the research directions on TCP/IP congestion control in the future are also proposed in this paper.
