1. A method for power level management of optical communications, the method comprising:

  • receiving a plurality of path setup messages corresponding to a plurality of light paths from a remote optical node, each of the path setup messages identifying one of the light paths and indicating a power level variation value for the identified light path; and

    for each of the path setup messages;

    determining drop power level variation for the light path identified in the path setup message;

    adding the drop power level variation to the power level variation value in the path setup message to obtain an aggregate power level variation for the identified light path;

    generating a setup reply message indicating the identified light path and the aggregate power level variation for the light path; and

    communicating the setup reply message to the remote optical node.
