Abstract: In this paper, we discuss the reasons and solutions of congestion in network, and mainly research the congestion cotrol in TCP network, and then expatiate the several arithmetics in TCP nework. Through the compartison of their principle and performance ,the author points out the available and effective solution for the present network .
