A Wavelength Switched Optical Network (WSON) requires certain
key information fields be made available to facilitate path
computation and the establishment of Label Switched Paths (LSPs).
The information model described in "Routing and Wavelength
Assignment Information Model for Wavelength Switched Optical Networks" (RFC 7446) shows what information is required at specific points in the WSON.  Part of the WSON information model contains aspects that may be of
general applicability to other technologies, while other parts are
specific to WSONs.

This document provides efficient, protocol-agnostic encodings for
the WSON-specific information fields.  It is intended that protocol-
specific documents will reference this memo to describe how
information is carried for specific uses.  Such encodings can be used
to extend GMPLS signaling and routing protocols.  In addition, these
encodings could be used by other mechanisms to convey this same
information to a Path Computation Element (PCE).

This document is a product of the Common Control and Measurement Plane Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
