  • Path engine for optical network
    Patent number: 7289448
    Abstract: A method and system for selecting ring paths in service provisioning on optical networks including a plurality of interconnected rings. The method includes: receiving a request to provision a service between a first end point and a second end point in the optical network; identifying a plurality of possible ring paths between the first and second end points; validating a bandwidth of each ring path, including validating bandwidths of bandwidth bottlenecks in each ring path; selecting a path from the validated ring paths; and provisioning the service on the selected path. The system utilizes a path engine on a network management server that knows about the bandwidth allocation in the entire network and implements the method. The resources of the optical network used by the provisioned service is thus minimized.
