Abstract

A Wavelength Switched Optical Network (WSON) is a Wavelength Division Multiplexing (WDM) optical network in which switching is performed selectively based on the center wavelength of an optical signal.

        Routing and Wavelength Assignment Information Encoding for                   Wavelength Switched Optical Networks

Abstract

   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).
