Abstract

The Hybrid CDN-P2P architecture, or HCDN, which combines the complementary advantages of CDN and P2P networks, has been proposed to reduce the deployment cost and to improve the quality of service in file sharing and video streaming applications. A replica placement algorithm (RPA) decides where to replicate the specific data. Existing RPAs for pure CDN do not work efficiently in the HCDN architecture because they do not take into consideration the contribution of the peers at the P2P distribution level. In this article, a heuristic RPA that takes into account the effects of P2P distribution is proposed for HCDN. The performance of our proposed algorithm is evaluated and the impact of some key metrics is analyzed. The experimental result shows the clear performance benefits of our approach.
