Research of Identifying P2P Protocols Based on P2P Traffic Characteristics
Zhou Lei-ge · Computer Technology and Development · 2009
The P2P traffic played a huge role in the Internet promoting.At the same time it has also brought occupation,network congestion and safety problems.It is necessary to have a control over the P2P traffic.However,with the emergence of dynamic port and SSL,the P2P traffic identification is becoming more and more challenging.This article briefly introduced the main technologies of P2P traffic identification including the routing way such as port scan,deep packet inspection and transport layer identification,and makes a heavy weight on the analysis about the reasons of low efficiency of the technique based upon P2P traffic characteristics.Finally,this method shows high efficiency in the test experiment.
