Modeling and Analysis of Resource's Load-Scale in P2P Network

Convenient, rapid, efficient and anonymous characteristic of P2P technology, enables P2P network gathering enormous users very quickly, and P2P traffic has occupied 60~80% bandwidth of Internet. Such giant traffic has formed a threat to the service quality of other Internet application and the security of Internet itself. However, most study about P2P traffic focuses on traffic monitoring and characteristic identifying technique. Rare study analyzes P2P traffic behavior from P2P mechanism itself. This paper construct P2P network queuing model, analyzes the influence of related factors to the load-scale of concrete resource. Main conclusion including, compared with other factors, average degree of node and TTL value is the most key factor to load-scale. Load-scale increases with node quantity, initial number of objected resource and resource’s total quantity, however, when those quantity reach to some critical threshold, the influence of those factors become quite weak to load-scale of resource.
