| 摘 要： | 近年来,随着P2P软件的增长,P2P的运行机制也变得多种多样。依靠单一的检测方法已经很难准确区分P2P流量和正常流量,而越来越多的加密P2P协议也给检测带来了极大的挑战。因此,文中首先讨论“Connection ResponsedSuccess Rate“方法,该方法通过流量分析中的连接特征来识别已知和未知的P2P流量。然后,对该方法的优缺点进行分析,指出其不足之处并对此加以改进。通过核密度估计对结果进行处理,辅以“双向传输流“方法弥补其检测的不足,以提高该方法的识别精度。最后,通过对实际采集到的网络流量进行分析,以验证所提出方法的准确性。

| Abstract: | In recent years,the P2P applications have resulted in a significant P2P traffic increase,the wide use of the P2P application has made the mode of P2P becomes more and more diverse.Relying on a single method is difficult to accurately distinguish between P2P traffic and normal traffic.The paper discusses the Connection Response Success Rate,which bases on connection features of traffic analysis to identify the P2P traffic.Then it analyzes the advantages and disadvantages of the Connection Response Success Ra... |
