A routing-selection algorithm is important in survivable wavelength-division networks. A sound algorithm should carefully consider the efficiency of resource utilization and the protection-switching time. Under shared-risk link group constraints with differentiated reliability (DiR), a novel algorithm for a shared path, called a joint routing-selection algorithm (JRSA) with DiR, is proposed. The simulation results show that a JRSA with DiR not only can efficiently satisfy the specific requirements of users but also can produce nearly optimal performance and determine the appropriatetrade-offs between the resource utilization ratio and the protection-switching time.
