1. A network element, comprising:
a processor and a non-transitory computer readable memory storing instructions that, when executed by the processor, cause the processor to:
obtain and store at least one loading policy for a transmission line segment that is currently operating, the at least one loading policy comprising a combination of loading parameters and one or more loading algorithm for one or more loading management operation type associated with the transmission line segment;
activate at least one of the at least one loading policy;
receive a plurality of requested service operations to change a spectral loading pattern of the transmission line segment, the requested service operations identifying a plurality of loading management operations to be executed in either of a current loading management operation cycle or one or more subsequent loading management operation cycle;
obtain one or more static datapoint and one or more dynamic datapoint associated with the transmission line segment;
obtain the loading parameters and the one or more loading algorithm from the at least one of the at least one loading policy that was activated;
generate, according to the one or more loading algorithm, a loading response based at least in part on the one or more static datapoint, the one or more dynamic datapoint, and the loading parameters from the at least one of the at least one loading policy that was activated, the loading response identifying a subset of the loading management operations to be executed in the current loading management operation cycle; and
change the spectral loading pattern of the transmission line segment based on the loading response.
