Title:
METHOD AND APPARATUS FOR GUARANTEEING A FAILURE-RECOVERY TIME IN A WAVELENGTH-DIVISION MULTIPLEXING NETWORK
Document Type and Number:
WIPO Patent Application WO2004054116
Kind Code:
A3
Abstract:
One embodiment of the present invention provides a system that guarantees a stated failure-recovery time in an optical wavelength-division multiplexing (WDM) network. The system operates by first receiving a request at an ingress node of the WDM network to establish a connection from a source to a destination through the WDM network, wherein the request includes the stated failure-recovery time. The system then calculates a chain of restorable cycles within the WDM network between the ingress node for the source and an egress node for the destination, wherein each cycle in the chain of restorable cycles can guarantee the stated failure-recovery time. Finally, the system selects a section of each restorable cycle to be a primary path between the source and the destination through the restorable cycle.
