Claim One:
1. A method of managing an optical communication network comprising a plurality of nodes, the plurality of nodes including at least two regeneration sites, the method comprising maintaining, by each regeneration site, a reach table containing information of a set of viable optical paths defining a respective local region of the regeneration site, each viable optical path of the set extending from the regeneration site and terminating at a respective photonically reachable neighbor nodes of the regeneration site and being configured to support a photonic connection between the regeneration site and the respective neighbor node; and computing, by each regeneration site, a connection through the respective local region of the regeneration site by: identifying, using the reach table, each one of the set of viable optical paths extending from the regeneration site; and for each identified viable optical path, sending a request message to the respective neighbor node terminating the identified viable optical path.
