摘要: 介绍一种基于三态内容可寻址器件及TCP速率的控制机制,研究吉比特链路的P2P流量检测与控制方法,提出一个PM模型,采用高精度的特征码匹配方法以识别P2P数据包,依概率对P2P数据包进行随机丢弃,从而达到控制高带宽P2P流量的目的。仿真实验结果表明,该模型可根据丢弃概率有效地控制P2P流量,改善非P2P应用的服务质量。

Abstract: A control mechanism based on Ternary Content Addressable Memory(TCAM) and TCP rate is introduced. The P2P flux detection and control method for gigabit link is researched. On this basis, a PM model is presented. The PM model uses high precision feature matching method to identify P2P data packets. According to the probability, P2P data packets are given up randomly, which controls high bandwidth P2P flux. Simulation results show this model can effectively control the P2P flux according to the discarded probability and improve Quality of Service(QoS) for non-P2P application.

Key words: flux control, high speed network, Ternary Content Addressable Memory(TCAM)
