  • Patent number: 10727973
    Abstract: Systems and methods for self-characterization of a software-defined optical network are disclosed. A test transponder may generate and transmit test traffic using various combinations of transmission parameters to discern physical characteristic of a route between two network elements. The test transponder may compute optical characteristics of the route based on the physical characteristics and transmission parameters. An SDN controller may maintain a characterization database storing test results. The test results may be fed to a machine learning engine, which outputs predictions or recommendations regarding utilization of bandwidth and other resources. The optical network may be adapted to handle requested, observed, or predicted changes in on-demand traffic or traffic surges. The test results may be used to defragment the optical spectrum with minimal or no impact on existing traffic to make space in a flexible grid for newly launched channels or channels being moved to different spectrum locations.

  • Patent number: 10708141
    Abstract: Disclosed is a method of commissioning a tributary blade in a disaggregated network system, including assigning a port ID to a port of an MCU, mapping to a port map a virtual slot ID to the port ID, receiving a registration request from a tributary blade, and assigning the virtual slot ID to the tributary blade. Disclosed is a method of determining whether a mis-cabling condition exists, including determining the whether a virtual slot ID is mapped to a port ID in a port map. Disclosed is a disaggregated network system including an MCU, a first and second tributary blade coupled to the MCU at a first and second port. The MCU is operable to assign a first and second virtual slot ID to the first and second tributary blades. The MCU is operable to map a first and second virtual slot ID to a first and second port ID.
