Abstract
A network component comprising at least one control plane controller configured to implement a method comprising transmitting a message to at least one adjacent control plane controller, wherein the message comprises a Type-Length-Value (TLV) indicating Routing and Wavelength Assignment (RWA) information. Included is a method comprising communicating a message comprising a TLV to a control plane controller, wherein the TLV indicates RWA information. Also included is an apparatus comprising a control plane controller configured to communicate a TLV to at least one adjacent control plane controller, wherein the TLV indicates RWA information.
