对RED的最大丢弃概率pmax和丢弃概率p进行了优化,NS2仿真实验结果表明,改进后的算法PO_RED,在网络轻载时,能同时提高TCP流和UDP流的性能;在网络重载时,能够抑制UDP流、增强TCP流,使网络资源分配更加公平。

It optimizes the maximum loss probability pmax and loss probability p of RED. According to simulation with NS2, the proposed algorithm PO_RED can improve the performance of both TCP and UDP flows while network light-load, restrain UDP flow and enhance TCP flow while network heavy-load. This makes the allocation of network resources fairer.
