Abstract
An apparatus comprising a first node configured to forward a wavelength assignment message to a second node, wherein the wavelength assignment message comprises a wavelength set type-length-value (TLV), a wavelength assignment method selection TLV, a supplemental wavelength assignment information TLV, a traffic parameter TLV, or combinations thereof. Also included is a network component comprising at least one processor configured to implement a method comprising obtaining a wavelength set data, a wavelength assignment method selection data, a supplemental wavelength assignment data, a traffic parameter data, or combinations thereof, and using at least one TLV to represent the obtained data. Also included is a method comprising obtaining a wavelength assignment information comprising a wavelength set, a supplemental wavelength assignment information, a wavelength assignment method selection, a traffic parameter, or combinations thereof, and forwarding the wavelength assignment information along a path.
