              YANG data model for Flexi-Grid Optical Networks
                   draft-ietf-ccamp-flexigrid-yang-06.txt

Abstract

   This document defines a YANG module for managing flexi-grid optical
   networks. The model defined in this document specifies a flexi-grid
   traffic engineering database that is used to describe the topology of
   a flexi-grid network. It is based on and augments existing YANG 
   models that describe network and traffic engineering topologies. 

   A partner document defines a second YANG module for flexi-grid media
   channels, i.e., the paths from source to destination through a number
   of intermediate nodes.
