There is a lot of congestion phenomenon in the Internet.Aim at that,we need safe,reliable Quality of Service in the Internet.Based on studying the principle of TCP/IP congestion control,this paper analyses a RTT-based arithmetic for solving the congestion control.In view of the possibility of congestion with the RTT increase,the arithmetic joins the side on the detection of RTT values,and in accordance with the relevant policy control cwnd value within reasonable limits.Using NS2,this arithmetic is lower packet loss rates than TCP by observation analysis.It can improve the throughput of the TCP connection and available bandwidth.Then analysis of result proves that the novel congestion contro1 algorithm can speed congestion recovery control on a certain extent,and decrease the vibration.
