Abstract
A computer-implemented method is implemented in one of a Network Management System (NMS), an Element Management System (EMS), a Software Defined Networking (SDN) controller, and a server executing an SDN application, to increase capacity of one or more links in an optical network. The computer-implemented method includes determining Net System Margin comprising a metric of overall excess margin in the optical network until a Forward Error Correction (FEC) limit is reached; performing an optimization of a plurality of parameters of the optical network to determine which settings are appropriate in the optical network to provide the increased capacity and to consume at least part of the Net System Margin; and causing a plurality of modems in the optical network to change settings based on the optimization to provide the increased capacity.
