INFORMATION COMMUNICATION APPARATUS AND COMMUNICATION PATH CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To select an optimal path out of a plurality of paths while attaining load distribution and communication path stabilization for tree-shaped communication paths.

SOLUTION: A gateway node GN1 constructs a cluster C1 comprised of a plurality of communication nodes in accordance with cluster conditions. The gateway node GN 1 and communication nodes N1-N35 exchange messages M2 containing path costs to route nodes, communication path holding conditions, cluster conditions, and traffic situations. Communication nodes within the cluster construct a communication path using the path costs calculated from static parameters which are not related to traffic. On the other hand, communication nodes out of the cluster construct a communication path using the path costs and the traffic situation that is a dynamic parameter relating to traffic.
