Abstract:
Systems and methods of path computation and setup via a control plane in a network with partial connectivity in a photonic layer include responsive to one or more nodes in the photonic layer having partial connectivity, receiving connectivity information of the one or more nodes in signaling messages at an originating node providing setup messages; storing the connectivity information of the one or more nodes and utilizing the connectivity information for path computation; after path setup of a service through the one or more nodes, periodically sending probe signaling messages over the service; and receiving probe response messages containing updated connectivity information of the one or more nodes and storing the updated connectivity information.
