This paper addresses the protection problem in WDM optical networks and presents a New Shared-risk link groups (SRLG)-Disjoint Path Provisioning (NSDPP) approach with shared protection to tolerate the single-risk failure. Comparing to previous Shared-risk link groups (SRLG)-Disjoint Path Provisioning (SDPP) approach, NSDPP is able to obtain better performance, because in NSDPP some primary path and backup paths of other primary paths can share the common resources if the corresponding rules can be satisfied. Simulation results are shown to be promising.
