| Abstract: | In this paper, we present a method based on network layer and transport layer for peer behavior a- nalysis. The method adopts the peersp communication status distribution, size and distribution of packets, transport layer protocol and port number to analyze the peer communication behavior. The experiments on PPLive, PPStream and QQLive proved that the method can clearly reflect the difference of peer behavior of different live streaming softwares. |
