摘　　要：针对目前IP网络P2P流量识别和管理的问题,提出一种基于节点的有状态识别NSI方法,设计并实现了基于该方法的P2P流量管理系统。NSI方法从节点双方的通信过程中寻找特征数据,进行特征匹配,并记录匹配节点,一旦该节点被识别出来,后续同该节点通信的数据就无须重新验证,因此极大的提高了系统的性能。在运营网络进行的测试表明,基于NSI的P2P流量管理系统能有效解决P2P应用所带来的流量管理问题。In view of the current IP network P2P traffic identification and management problems, put forward a Node-based Stateful Identification （NSI） method, design and realization a P2P traffic management system based on the method. NSI method find the features of data from the nodes in the communication process between the two sides, matching features and to record the matching node, once the node is identified, follow-up communication with the nodes of the data would be no need for re-authentication, thus greatly improve the performance of the system. Test on the operator networks shows that the P2P traffic management systems based on NSI can effectively solve the flow management problems caused by P2P applications.
