<p><P>PROBLEM TO BE SOLVED: To provide a communication system, capable of restoring a P2P network, when an optional node which participates in the P2P network is detached without making a certain node redundantly hold information. <P>SOLUTION: A P2P type ring network is composed into a content oriented structure, and registration of place information of a content to each node is dispensed with by making content nodes participate in the ring network. When a certain node is detached, or the content node is detached from the ring network, a downstream-side content node of the detached content node searches an upstream-side content node of the detached content node to connect the both, whereby the ring network is repaired. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
