<p>PROBLEM TO BE SOLVED: To automatically set a route selecting address over a plurality of physical networks by giving preference to one of a plurality of route selecting addresses based on priority order information, changing the other simultaneously with or before/after the preferred address and setting the route selecting address having singularity. SOLUTION: The optical route selecting address is given to a plurality of nodes first. In a succeeding step, priority order information is given to the optional route selecting address. As the way of giving priority order in the step, intrinsic priority order information given to the node or an output interface can be used or another kind of information can be used. In the next step, preference is given to one of the plurality of route selecting addresses based on the priority order information, the other is changed simultaneously with or before/ after the preferred address and, then, the route selecting address with the singularity is set.</p> |
