Abstract:

To improve the number of TCP(Transfer Control Protocol) flows, the average sending rate, to reduce the volatility of the rate of sending a few to improve network performance, adaptive parameter settings is proposed based on AIMD (Additive Increase Multiplicative Decrease) algorithm (A-AIMD algorithm). Simulation results show that the network is in steady-state operation, the use of A-AIMD algorithm can improve the TCP  stream, the average sending rate, reducing the sending rate volatility.The network has the link available resources the use of A-AIMD algorithm can quickly occupied most of the resources available at the same time with the Reno algorithm to maintain a certain degree of TCP-friendly.

Key words: communication technology, transfer control protocol(TCP) congestion control, additive increase multiplicative decrease(AIMD), TCP-friendly
