<p>PURPOSE:To realize transmission in plural lines and to exterminate the impossibility of relay, by setting plural routes in each area and between areas, and finding an output line by routing from the correspondence table between a route number and the output line by respective node. CONSTITUTION:Firstly, the plural routes numbered between two nodes in the area are defined, and similarly, the plural routes are defined between the areas. Those are expressed as (a node (i), a node (j): route number), and (an area (l), an area (m): route number) respectively, and those become identifiers which represent (an outgoing node, the output line, a relay node 1, the output line 1, a relay node 2, the output line 2,..., an incoming node). Each node is provided with a route end point being connected to another area, and stores a node number, and also, provided with a route managing table in a domain, that is, the correspondence table between the route number and the output line, and the node having the output line finds the output line from a routing table between the areas. A message is transmitted after attaching the area number of an opponent, the node number, and the route numbers in and between the areas. Thereby, it is possible to transmit the message in the plural routes.</p> |
