With the development of Internet and Broadband technology,P2P is used wider and wider.However,The development of P2P applications has led to a lot of problems,such as accused of copyright laws,spreading Trojan horses and virus,occupying most Bandwidth resources and causing the environmental of network be much worse.Nowadays,the problems caused by P2P has become a key issues of the problems of network.How to solve these problems caused by P2P and control the P2P traffic effectively,have become a high preferential issues for many Network operators and corporation.The traditional fixed port couldn't precisely detect the P2P flow rate,while as a relatively simple and highly efficient data flow detection technology,DPI is utilized in P2P flow monitoring control,greatly promoting identify efficiency and accuracy of the protocol.Take KuGoo2008 as an example,adopting DPI principle,I analyze the correspondence mechanism and parse the fingerprint characteristic of KuGoo protocol.Finally,I propose an optimized design of P2P Detection System which is on the purpose of examining and detecting P2P traffic.P2P Detection System will release network band width and alleviate pressure on the network.
