P2P流量识别技术综述

在归纳P2P流量识别问题概念的基础上,对现有的P2P流量识别技术进行了较全面地分析.借助分类模型形式化地定义P2P流量识别问题,依据所采用的识别特征将已有技术分为基于端口号、基于流量特征、基于应用层签名、基于双重特征和基于统计行为特征五类方法,并对各类方法进行了介绍、分析与优劣对比.探讨了新兴的P2P流媒体流量识别问题,总结了P2P流量识别技术的发展趋势.

Survey of P2P traffic identification

A comprehensive study of existed P2P traffic identification method based on the definition of P2P traffic identification was introduced. The problem of P2P traffic identification was defined though the classification model. Five methods which were port-based, traffic features based, application signatures based, hybrid features based and statistical behaviors based approaches were classified from exsited technology according to the recognition feature, and the analysis and comparison of them were discussed. In addition, the traffic identification issue for the newly emerging P2P streaming was explored. Finally, the development trend of P2P traffic identification was given.
