Performance Evaluation of Content Distribution in Hybrid CDN-P2P Network

Hybrid content distribution network (HCDN), integrating complementary advantages of CDN and P2P, is used to improve efficiency of large-scale content distribution. In this paper, to achieve in-depth understanding of HCDN¿s effectiveness, we carry out a detailed performance evaluation based on deterministic fluid model. We also provide numeric results of HCDN, comparing with conventional CDN and P2P. Some performance metrics are taken into account in our analysis, such as the evolution of the number of seeds and downlowders, the service capacity of system and the average downloading time.
