- The backup paths just SRLG (Shared Risk Link Group)-disjointed with working paths can be concentrated on a specific link. Thus, the idle resource is not used efficiently so that the resource utilization of the network is not so good. We propose the resource share backup path provisioning mechanism to guarantee the survivability and to utilize the network resource. We consider SDLG (Sub-Domain Link Group) as the information to eliminate the link accommodated the unbalanced sharing backup paths. We compare our mechanism with the existing mechanism, which allocate the backup path just SRLG-disjointed with working path. We also apply the diversity network plans to the mechanism to select the backup paths. In addition, to control the backup paths we use GMPLS (Generalized Multi Protocol Label Switching) according to the consensus, which is emerging in the industry on utilizing an IP-centric control plane within optical networks to support dynamic provisioning.
