Simulation on improved two-tier hybrid P2P network model

The OPNET simulation software is used in the simulation on the two-tier hybrid P2P network model.A comparative analysis on the response time of search and the utilization of network link is made between the improved two-tier hybrid P2P network model and the traditional unstructured P2P network.The results of the simulation prove the good performance and stability of the two-tier hybrid P2P network model.So the user interest to visit web services actuated by the stable interest is higher than by the accidental interest,in a fixed time compartment the user had the stable interest characteristic.
