Identification of peer-to-peer traffic based on process fingerprint

In local area network (LAN), the large-scaled peer-to-peer (P2P) application has aroused our attention by its convenience as well as the problems inborn. The network traffic and the resources consumed have severely influenced the usage of other network application, and this makes the study of identification on P2P traffic much more significant. This article advances an identification method based on the host process fingerprint, which can be done on the client computer with P2P application on. Experiments show that method has a high classification capability on the P2P traffic in LAN.
