| 摘 要： | 为提高TCP（Transfer Control Protocol）流的平均发送数率,减少发送数率的波动,提高网络性能,提出了一种基于自适应参数设置的AIMD（Additive Increase Multiplicative Decrease）算法（A-AIMD算法）。仿真结果表明,在网络处于稳态运行时,使用A-AIMD算法能提高TCP流的平均发送速率,减小发送速率的波动性;在网络中有可利用的链路资源时,使用A-AIMD算法能快速地对可用资源进行最大占用,同时与Reno算法保持一定的TCP友好性。

| 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. |
