1. A network component comprising:
- at least one control plane controller configured to;
transmit 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, andwherein the RWA information indicates whether a network element is fixed or reconfigurable.

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.

21. A method comprising:
-
transmitting a type-length-value (TLV) that describes a plurality of links in a link set, wherein the TLV comprises; an action field that indicates either that one or more link identifiers are included in the link set, or that indicates that the link set defines a range of links; a directionality field that indicates whether the link set is bidirectional, ingress, or egress; a format field that indicates whether the links in the link set are identified by link local identifiers; and at least one link identifier. - View Dependent Claims (22, 23)

24. A method comprising:
-
transmitting a type-length-value (TLV) that describes a plurality of wavelengths in a label set, wherein the TLV comprises; an action field that indicates that the label set is an inclusive list, and exclusive list, and inclusive range, and exclusive range, or a bitmap; a field that indicates the number of labels represented by the bitmap when the action field indicates that the label set is the bitmap; and a label that indicates a wavelength. - View Dependent Claims (25)
