摘要

A group of nodes mutually connected through a communication route form an information communication system. The nodes include a memory for memorizing node information indicating a candidate node of information transfer destination, a participation request information transfer unit for judging whether node information indicating a node of a transfer destination in response to information of the participation request node is memorized, when participation request information is received, and for transferring the participation request information to the node when the node information is memorized, an existence confirmation information sending unit for judging whether information of other than the transfer destination is memorized when the participation request information is received, and for sending existence confirmation information to the node when the information other than the transfer destination is memorized, and a unit for sending return information to the participation request node device when the existence confirmation information is received.
