With widely application of Peer-to-Peer (P2P) file sharing technique, the P2P traffic occupies most of the current Internet bandwidth. Modeling the behaviors of P2P file sharing systems is important for designing and evaluating such systems. In this paper, we develop a novel model to character the dynamic behaviors of P2P sharing systems. States in microcosmic view are defined and used to describe the interaction among the peers in systems. Then, a model in general form for P2P sharing systems is proposed. According to common software policies in P2P systems, we embody the model. To verify the validity and reasonability of the proposed model, P2P simulations are conducted.
