Abstract
A network component comprising a control plane controller configured to implement a method comprising transmitting routing and wavelength assignment (RWA) information to at least one adjacent control plane controller, wherein the RWA information is transmitted using an interior gateway protocol (IGP). Included is a method comprising communicating a message comprising RWA information to at least one adjacent control plane controller, wherein the message comprises an indication whether the RWA information is static or dynamic. Also included is an apparatus comprising a control plane controller configured to communicate data to at least one adjacent control plane controller, wherein the data comprises RWA information, and wherein the data comprises an indicator that indicates whether the RWA information is associated with a node, a link, or both.
