A New Method and FPGA Implementation of P2P Traffic Identification for EPON

P2P protocol is widely used in many network applications. Recently, p2p traffic reserves a big part of total access bandwidth and may cause serious problems in EPON. In this paper, a new method to identify the p2p traffic based on the flow ID (five-tuple) is presented. We analyze the factors that influence identification accuracy, and then simulate accurate rate of the new method according to the analysis, the results show that the analysis is right and the new method can have high accuracy if designed appropriately. We also give FPGA implementation of this method. The new method is suitable for real-time traffic monitoring.
