PMIMD拥塞控制算法

PMIMD Congestion Control Algorithms

分析了目前在Internet上占主导地位的AIMD算法 ,指出了其在保持数据流稳定性上的不足 ,这一缺点不能适应当前的媒流体文件传输 ;提出了一种新的算法———PMIMD(比例乘性增加乘性减少 )。仿真结果表明 ,本算法能减少控制的超调量 ,从而降低传输率的波动。

In this paper,we analysis the AIMD algorithms which has been used in many congestion control protocols in the Internet. We point out that the AIMD algorithms is not fit for transfers of real-time streaming file because the AIMD algorithms can not keep the flow steady. We design a new algorithms-PMIMD (proportion multiplicative increase and multiplicative decrease). We confirm experimentally that the new algorithms is effective in keeping the flow steady.
