校园网P2P流量综合检测及实时控制设计

Design of P2P Traffic Monitoring and Controlling Technology of Campus Network

互联网上有关P2P的应用层出不穷,其产生的流量占网络总流量的40%~70%,对网络的带宽造成巨大威胁.而通过一种手段对P2P应用进行识别往往精度不高,针对校园网中的P2P应用,提出一种利用P2P的3种典型特征进行综合检测的方法,并对校园网进行试验,证实将P2P流量控制在一定范围内是可行的.

P2P applications on the Internet follow fast.P2P traffic has taken up 40% to 70% of the total Internet traffic,and P2P can bring enormous threat to Broad Band Internet.But we often have a low identification precision by one method,in this article we aim at P2P applications of campus network,then a multifunctional identification method based on three typical features is proposed.A test has been made in the campus network,which proves that identify and control the P2P traffic in some range is practical.
