A Yang Data Model for Optical Impairment-aware Topology
draft-ietf-ccamp-optical-impairment-topology-yang-05
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.
