Abstract

The interest of peer in CDNonP2P shows the requirement of resources. This paper analyses the structure of CDNonP2P based on interest subnet grouping,and studies the basic type of content delivery algorithms for subnet grouping. An algorithm that selects a user peer as the CDN peer according to its status is proposed. Interestweight is used to show the correlation of the user peer resources. In this algorithm,a user peer is selected as the CDN peer based on setting conditions.The experimental results show that the algorithm decreases the mount of CDN peers,improves the reliability of CDN,and reduces the network traffic.
