Abstract


P2P network is one of the most important applications on the Internet. Its popularity makes resource sharing on the Internet much easier, in the mean while the control and supervision of the information becomes harder and harder. P2P network can work without any center, which makes the administrator hard to locate the harmful information on the Internet, and there isn’t any good way to supervise and control it. P2P network has raised a big challenge to the information supervision on Internet.This Paper introduces the development and technology of P2P network, including topology of network and features of peers, and specifies the two popular P2P protocol: Bittorrent protocol and eDonkey protocol, including how they work. Then this paper introduces three classic diffusion model: SI Model, SIS Model and SIR Model.Based on the classic diffusion model of virus, with consider of the features of P2P network, this paper propose a diffusion model of a complex, quick, large-scale P2P network, and the model is verified and optimized based on the data from many experiments. At last, this paper implements a supervision system to analyze the diffusion of BT download and eMule download. The system can predict the diffusion trend of the resources and locate all the nodes that are relevant to the diffusion.
