Title:
METHOD AND SYSTEM FOR NETWORK RECONFIGURATION IN MULTI-LAYER NETWORK
Document Type and Number:
WIPO Patent Application WO/2012/026132
Kind Code:
A1
Abstract:
The present invention is capable of performing flexible and cost-efficient reconfiguration of a higher-level layer network corresponding to changes in the status of the network in a multi-layer network. Each node of each layer has an event-operation database (305) in which event-operation correspondence information is stored, and an operation execution control unit (304) which refers to the event-operation correspondence information generated by events in order to execute corresponding operations; wherein operations are transmissions to specific nodes of messages which indicate event occurrences, settings of paths based on links in at least one higher-layer network, or combinations of the transmissions and settings. With nodes (N15 and N13) which have detected the occurrence of a predetermined event as origins, the sequentially specified nodes execute the operations while referring to the event-operation correspondence information that has been stored in the nodes, thereby automatically reconfiguring the higher-level layer network (L204).
