ABSTRACT:
Traffic characteristics of virtual paths 140 through 142 are monitored. A network node 120 notifies a network management system 170 that the traffic characteristics exceeds a predetermined threshold value, if it happens. The network management system 170 establishes an optical path 220 between certain network nodes 100 and 130 and use the optical path to transfer the virtual paths 141 and 142 multiplexed with optical paths 160 through 162 previously established for the individual transmission paths. On the other hand, the virtual paths 141 and 142 transferred on the optical path 220 are inverse switched into the optical paths 160 through 162, when the traffic characteristics for the virtual paths 141 and 142 are within the threshold value.
