一种对非TCP友好流的实用无状态惩罚算法

A stateless penalty algorithm for non-TCP friendly flow

本文提出了一种新的对非传输控制协议（ＴＣＰ）友好流的惩罚机制一垃圾桶算法，该机制通过利用已经被丢弃的分组的信息来加强对非ＴＣＰ友好流的识别及惩罚。仿真结果表明，在不保持流的状态下，该机制对非ＴＣＰ友好流有较强的区别和控制能力，与ＣＨＯＫｅ相比，能够进一步加强对非ＴＣＰ友好流的惩罚和实现更为公平的带宽分配。

Internet has become facing crisis of 'congestion collapse'once again because of the appearing of Non- TCP friendly flow. Trash-a stateless penalty algorithm for non-TCP friendly flow is proposed in this paper.By keeping the information on discarded packets, the algorithm can discriminate and punish against the flow which submit more packet than is al1owed by their fair share.Simulation results show that our algorithm has better penalty performance in fairness of bandwidth allocation than that of CHOKe.
