    摘要: A method of providing routes through heterogeneous subsystems in an optical network is disclosed, which includes generating, using a processing device, a reachability matrix based on subnetwork information; and generating, using the processing device, a topology associated with the optical network using the reachability matrix. The method also includes determining, using the processing device, a shortest path through the optical network using the reachability matrix and a cost model graph; and displaying, using a graphical user interface, subsystems associated with the shortest path, regeneration locations associated with the shortest path, wavelengths associated with the shortest path, the topology, and the shortest path. Corresponding apparatus and computer-readable storage media are also disclosed.

    摘要: A resilient load balancing method uses fixed paths and a fixed path-splitting strategy to enable ingress routers to efficiently reroute traffic after a failure. An off-line management system computes a set of fixed paths and a set of splitting ratios for routing demand from ingress routers to egress routers, with sufficient capacity to meet demands under each failure scenario. That data is then used by the ingress router to reroute demand after observing a failure.

    摘要: Systems and methods of multicast configuration are provided. A particular method includes detecting a failure in the data network at a first node of a data network. The method also includes determining an alternate route from the first node to a data source of the data network. The alternate route includes a second node as an upstream node. The method further includes determining whether the alternate route would create a loop in the data network. The method includes setting a state of the first node to a waiting-to-join the second node state when the alternate route would create a loop.
