Distributed P2P Traffic Identification Method

It is important to identify P2P traffic accurately for effective network planning and design, security insuring, network management, network behavior understanding and so on. Firstly, some different techniques for identifying P2P application traffic are analyzed, advantages and disadvantages among them are compared and then difficulties are discussed. Secondly, a distributed method for identifying P2P traffic (DPTIM) is presented, modules and their relationship for implementing this method is introduced. P2P traffic identification and statistic are separated in DPTIM and Netflow is used to process flow aggregation, which improves efficiency for identification and reduces complexity for implementation in distributed environment. Finally, one prototype system based on DPTIM is proposed, which establishes foundation for P2P traffic identifying and controlling in cosmically environment.
