Considering Share Risk Link Group (SRLG) constraints , a algorithm called SRLG with Conditional Failure probability (SCFP) is proposed in order to provide differentiated services in WDM mesh network. SCFP can differentiate the requirement on service reliability based on analysis of Conditional Failure Probability (CFP). In this algorithm, the concept of CFP is provided from reliability probability that user requires. Then a pair of routes satisfying CFP is computed, and also the routing trap is solved. Simulation results show that SCFP effectively reduces the Blocking probability and keeps in a high resource utilization rate.
