Internet-Draft WSON Information Model March 2012
This document is subject to BCP 78 and the IETF Trust's Legal
Provisions Relating to IETF Documents
(http://trustee.ietf.org/license-info) in effect on the date of
publication of this document. Please review these documents

Abstract
This document provides a model of information needed by the routing
and wavelength assignment (RWA) process in wavelength switched
optical networks (WSONs). The purpose of the information described
in this model is to facilitate constrained lightpath computation in
WSONs. This model takes into account compatibility constraints
between WSON signal attributes and network elements but does not
include constraints due to optical impairments. Aspects of this
information that may be of use to other technologies utilizing a
GMPLS control plane are discussed.
