摘要:
P2P应用近年来取得了飞速的发展,在推动Internet发展的同时也带来了大量带宽占用和网络安全问题。P2P节点的识别是P2P流量检测中一类重要的方法。通过理论和实验两方面分析了基于连接成功率的节点识别方法对P2P流媒体识别存在误判率高的缺点,并在此基础上提出基于主被动连接的识别算法。该算法在基于连接成功率算法基础上,通过计算节点在单位时间内,被动连接和主动连接数的比值进一步判断。实验结果显示,改进后方法比原方法有更小的误判率和漏判率,提高了检测的准确度
Abstract:
With the wide application of the P2P,it has brought bandwidth occupation and safety problems.The identification of P2P peers is one of the important methods in P2P measurement.Firstly,analyzes the＂connection responsed success rate＂in theory,then find the high false positive in identification of P2P streaming media by experiment.So the identification algorithm of P2P peers based on initiative and passive connections is presented.The algorithm computes the ratio of passive connections and initiative connections in unit time to identify P2P peer after connection responsed success rate method.The experiment results show that the algorithm proposed in this paper can identify P2P peers more accurately,with less false positive and false negative
