| With the growing of the campus network, network applications continue to increase, a file exchange methods-P2P technology subsequently developed. P2P application of its unique advantage become the majority of the user's favorite, but, P2P gave rise to "speed" enjoy the same time, but also to network management has brought about tremendous distress and inconvenience. The Peer-to-Peer network characteristic of "the bandwidth gobble up" result in the huge depletion of bandwidth, even cause the network congestion, lower the network performance, inferior turned the network service quantity. It is problem-solving key to identify and controle traffic flow of Peer-to-Peer.In this article, the author introduce the definition characteristics and the necessity of identifying traffic, analysize the application of P2P on campus and bring to the campus network problems, the author do research on the methods of Peer-to-Peer traffic identification then the author put forward a model based on traffic transport characteristic, the creative of the model is than it can identify traffic of P2P and do not check in data payload, the model can raise the efficiency of identify; the author study the strategy of traffic statisticses, the technique of traffic control and put forward a strategy of packet data scheduler and bandwidth allocation, For the user, reasonable allocation network bandwidth resources, alleviate the nervous present condition of resources, carry out the network resources on demand; and at last, the article gives the implement of the system. |
