摘要:In this paper, we propose a method to identify the P2P file sharing. In this method, we collect a large amount of network traffic and analyze the features of P2P file sharing by network layer and transport layers of OSI reference model. Four features are defined in this method, including quantity of packet count, percentage of TCP packet count, percentage of specific size of packet count, and percentage of duplicate destination port numbers. Based on our experiments, we can define the thresholds for each feature. Finally, we use four membership functions and a formula to identify the P2P file sharing.
