ABSTRACT:
Methods and apparatus for managing an optical network using pilot tones are provided. One method includes generating a list of pilot tones contributed by a selected node to each of its target nodes. Network pilot tone sources are re-configured so that a pilot tone source of any optical path incorporating one of the target nodes has a value distinct from the listed pilot tones. The selected node can then be added to the network. Another method includes generating a list including all selected network nodes to be incorporated into a new optical path and nodes adjacent to the selected network nodes. Network pilot tone sources are re-configured until a pilot tone source associated with the new optical path has a pilot tone distinct from that of any listed node. The new optical path can then be added to the network.
