<p><P>PROBLEM TO BE SOLVED: To provide a P2P content distribution system which can distribute the load on each peer and set up many peers. <P>SOLUTION: This system comprises a center network CE, a cache network CA and a plurality of realm networks RL1-RL3. A dynamic peer DP is divided into realm networks RL1-RL3. The center network CE consists of a main center server MC and a sub-center server SC. Each realm network has a sub-center server SC and forms a P2P system. The cache network CA has a cache center server CC and forms a P2P system with a static peer SP and a dynamic cache peer CP. The dynamic cache peer CP carries out caching of a static peer SP and becomes an origin of content distribution in the realm network. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
