基于连接模式的P2P流量识别的研究与实现*

提出基于网络层连接模式的P2P流量识别算法，并对识别过程中的几个关键问题进行了研究。提出采用分光技术对链路数据进行旁路处理，通过在链路层加入过滤策略减少对冗余数据的采集，对采集到的有效数据通过流归并技术进行预处理，并介绍了识别结果显示阶段的相关处理方法。

Research and realization of P2P traffic identification based on connection pattern

This paper introduced the algorithm of P2P traffic identification, which was based on the connection pattern of network layer, and the research on some important problems. The spectrometer copiedthe data of link to the network card; used the filtration strategy by data link layer in order to reduce the redundant data; the valid data would be processed with the method of flows merging. Finally introduced some processing methods adopted at the stage of data displaying.
