基于主机的P2P流量检测与控制方案

A Host-Based P2P-Traffic Detection and Control Scheme

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。由于P2P采用了动态端口等技术,使得传统的端口映射的方法对P2P流量的识别不再有效,如何有效地监测和控制P2P流量是网络测量领域一个重要的研究课题。介绍了各种P2P流量识别方法及优缺点,然后提出一种新型的检测与控制策略——基于主机的P2P流量检测与控制。实验结果及分析表明该方法能比较有效地检测P2P流量并具有更好的检测精度和控制效果。

P2P traffic has taken great portions in the network 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. Since more and more P2P applications are using dynamic random port nombers, the traditional port matching technology is becoming useless, therefore how to effectively identify and control the P2P applications has been a very important research work. Introduces methods in identifying P2P traffic and their characters, then puts forwards a host - based strategy of detection and control of P2P traffic. Experimental results show that the method is efficient for traffic identification and has a more accurate prieision and control effects.
