摘　　要：P2P流量逐渐成为了互联网流量的重要组成部分,在对Internet起巨大推动作用的同时,也带来了因资源过度占用而引起的网络拥塞以及安全隐患等问题,妨碍了正常的网络业务的开展。首先介绍了各种P2P流量识别方法及其优缺点,然后提出一种基于方差分析的P2P流量特征选择方法和基于该方法的支持向量机技术在P2P流量准实时检测中的应用模型。实验结果及分析表明,该方法能较有效地检测P2P流量并具有更好的检测精度。P2P traffic has taken great portions in the Internet traffic. While having a significant impact on the Internet, it brings serious problems such as network congestion and traffic hindrance caused by the excessive occupation in the bandwidth. The paper firstly introduced methods in identifying P2P traffic and their characters, then put forwards a P2P traffic feature selection method by exploring analysis of variance. Meanwhile a model based on Support Vector Machine （SVM） algorithm was set up to fulfill the quasi-real-time identification of P2P traffic. Experimental results show that the method is efficiency for P2P traffic identification and has a more accurate precision.
