Modeling VoIP service processes based on P2P network

In the process of VoIP services based on P2P network, the two fundamental operation, registration and session, are the most important operations of the user. Based on the analysis of the relationship between the process and the users' behavior, this paper introduces mathematical modeling of P2P VoIP service process. The modeling and simulation results provide the basis of the optimal node-configuration solution in a large-scale P2P VOIP telecom network environment.
