1. Introduction
This document provides a YANG data model for the routing and
wavelength assignment (RWA) Traffic Engineering (TE) topology in
wavelength switched optical networks (WSONs). The YANG model
described in this document is a WSON technology-specific Yang model
based on the information model developed in [RFC7446] and the two
encoding documents [RFC7581] and [RFC7579] that developed protocol
independent encodings based on [RFC7446]. This document augments the
the generic TE topology draft [TE-TOPO].
What is not in scope of this document is both impairment-aware WSON
and flex-grid.
