Title: SYSTEM AND METHOD FOR ABSTRACTING WAVELENGTH-SWITCHED OPTICAL NETWORK TRAFFIC ENGINEERING TOPOLOGY IN SDN CONTROL HIERARCHY
Abstract:
A method including determining, for each reachable source-destination (S-D) node pair, a maximal number of optical channel (OCh) paths available for source-destination node pair connections and determining, if a preselected latency threshold is specified, for all available OCh paths a maximal number of paths satisfying the preselected latency threshold. The available OCh paths are reported to a Multi-Domain Service coordinator (MDSC).
