摘要： A method and apparatus for optimizing optical transport using a software defined network (SDN) controller are disclosed herein. The SDN controller may define a margin optimization function based on at least one optical system performance metric. The function may include at least one related initiation criterion. Further, the SDN controller may collect at least one measurement for the performance metric. The measurement may include an assessment of deployed carriers not carrying client data. The SDN controller may determine whether the initiation criterion is met based on at least one collected measurement. The SDN controller may select a system margin optimization mechanism and define a system margin optimization threshold criterion on a condition that the initiation criterion is met. The SDN controller may determine whether the optimization threshold criterion is met. The SDN controller may implement one or more optimization events on a condition that the optimization threshold criterion is met.

摘要： A method and apparatus for pro-active protection of packet-optical transport in a software defined network (SDN) controller are disclosed herein. The SDN controller may define a proactive protection threshold criterion based on based on a plurality of optical system performance metrics and may collect at least one measurement for each of the metrics. The SDN controller may then determine whether the proactive protection threshold criterion is met based on at least one of the collected measurements. Further, the SDN controller may select a protection mechanism and define a protection threshold criterion on a condition that the proactive protection threshold criterion is met. Also, the SDN controller may initiate proactive protection events based on the selected protection mechanism. The SDN controller may determine whether the protection threshold criterion is met. The SDN controller may implement one or more protection events on a condition that the protection threshold criterion is met.
