| 摘 要： | 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。

| Abstract: | 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. |
