Abstract
The path management controllerrefers to resource informationincluding reservation statuses of working paths and advance reserved paths that are set in every link, so as to calculate a route for setting a new path and set this path in this calculated route. If the route for setting this new path cannot be obtained (1) because of a shortage of residual bandwidth of a link of interest, the path management controllerrefers to the resource reservation informationof working paths and advance reserved paths and calculates an alternative route for another existing path used in the link of interest, and moves this path to the calculated alternative route. On the other hand, if the route for setting this new path cannot be obtained (2) because there is no continuous bandwidth sufficient for setting this new path in the link of interest, the path management controllerrefers to the resource reservation information regarding working paths and advance reserved paths in the link of interest in the resource information, so as to execute the time slot rearrangement.
