Abstract
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.
Part of the WSON information model contains aspects that may be of
general applicability to other technologies, while other parts are
fairly specific to WSONs.
This document provides efficient, protocol-agnostic encodings for
the WSON specific information elements. 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).
