A wavelength switched optical network (WSON) requires that certain key information elements are made available to facilitate path computation and the establishment of label switching paths (LSPs). The information model described in "Routing and Wavelength Assignment Information for Wavelength Switched Optical Networks" shows what information is required at specific points in the WSON.
The information may be used in Generalized Multiprotocol Label Switching (GMPLS) signaling protocols, and may be distributed by GMSPL routing protocols. Other distribution mechanisms (for example, XML-based protocols) may also be used.
This document provides efficient, protocol-agnostic encodings for the information elements necessary to operate a WSON. It is intended that protocol-specific documents will reference this memo to describe how information is carried for specific uses.
This is a new "individual submission". Note that this means it is not a working group document (yet), and not that it was written by one person! Once again more examples and nice figures can be found in the paper "Modeling WDM Wavelength Switching Systems for use in Automated Path Computation". See attachments below for draft, editors working draft, and slides for Dublin July 2008.
