摘　　要：P2P流量逐渐成为互联网流量的重要组成部分,精确识别P2P流量对于有效地管理网络和合理地利用网络资源都具有重要意义。对P2P应用作了简要介绍,分析了P2P和传统C/S网络的不同,并介绍了目前主流的P2P流量检测技术,分析了这些技术的优缺点,然后结合P2P流量的payload特征,设计了一种基于深度包检测的P2P流量检测方法,并通过实验证明了此方法的可行性。结果显示该方法具有非常高的检测精度和令人满意的性能。P2P traffic has become one of the most significant portions of the network traffic. Accurate identification of P2P traffic makes great sense for efficient network managernent and reasonable utility of network resources. The application of P2P is simply presented, then the difference between P2P and traditional C/S network was analyzed. Introduces the advantage and disadvantage of the technology of P2P traffic identification, and then designed a method to identify P2P traffic based on the deep packet inspection combining the payload characteristic of the P2P traffic. Also proved this possibility of the method through an experiment. Experimental results show that the method has proper accuracy and low cost.
