<p><P>PROBLEM TO BE SOLVED: To provide a communication node that avoids a fault and transfers a message without the need for provision of a high capability and for maintenance and exchange of a huge amount of link state information items even when an address assigned to the communication node is not available for efficient route concentration. <P>SOLUTION: A management address and a routing ID range are set to each communication node, and each communication node divides the routing ID range on the basis of a prescribed routing ID division method to determine the routing ID to be in use, acquires the routing ID used by the destination communication node from the management address of the destination communication node in the case of message transmission, determines a source route through which communication nodes are passed up to a destination communication node according to the connection of the routing IDs determined by the routing ID division method, and transmits a packet including a destination address corresponding to the routing ID and the source route. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
