INFORMATION COMMUNICATION SYSTEM, INFORMATION COMMUNICATION METHOD, NODE APPARATUS INCLUDED IN INFORMATION COMMUNICATION SYSTEM, AND RECORDING MEDIUM IN WHICH INFORMATION PROCESSING PROGRAM HAS BEEN RECORDED

摘要

An information communication system and others wherein the communication load of the entire communication network has been reduced. In the information communication system comprising the participations of a plurality of node apparatuses mutually connected via the communication network, a node apparatus has a storing means that stores the IP addresses of one or more particular node apparatuses and the node IDs associated with those IP addresses for each of areas to which those node IDs belong. In a case where an area of the storing means, to which the node ID associated with a node apparatus (node K) that is a source of transmitting the received information belongs, has stored the node ID of another node apparatus (node A), if the number of HOPs form the node K to the local node apparatus is smaller than the number of HOPs from the node A to the local node apparatus, then the node ID is changed to the IP address and node ID of the stored node A, and the storing means is caused to store the IP address and identification information of the node K that is the source of transmitting the information. Thus, this information communication system can solve the problem.
