An Efficient P2P Overlay Network Model Based on Clustering

Article Preview

Abstract:

The P2P system was build with the topological structure of the network at the application layer, network topological structure for an P2P system has a very important significance. There is currently a wide range of different topology structure of P2P network, HCPON uses two-level clustering structure, based on HCPON, we propose an efficient overlay network model based on clustering (PONM), it solves the problem that the super node only uses a single backup node as a redundant backup leading system robustness improvement is limited in unstructured P2P system. The model through a directory server to manage all nodes on the network, The results of the simulation demonstrates that,compared with HCPON, PONM has a relatively stable path stretching rate and lower average link pressure, can meet the requirements of Large-Scale P2P streaming media service needs.
