          A Yang Data Model for Optical Impairment-aware Topology

           draft-ietf-ccamp-optical-impairment-topology-yang-00

Abstract

   In order to provision an optical connection through optical
   networks, a combination of path continuity, resource availability,
   and impairment constraints must be met to determine viable and
   optimal paths through the network. The determination of appropriate
   paths is known as Impairment-Aware Routing and Wavelength Assignment
   (IA-RWA) for WSON, while it is known as Impairment-Aware Routing and
   Spectrum Assigment (IA-RSA) for SSON.

   This document provides a YANG data model for the impairment-aware TE
   topology in optical networks.
