The IESG has received a request from the Common Control and Measurement Plane
WG (ccamp) to consider the following document: - 'A YANG Data Model for
Optical Impairment-aware Topology'
  <draft-ietf-ccamp-optical-impairment-topology-yang-20.txt> as Proposed
  Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@ietf.org mailing lists by 2025-11-10. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

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 a Wavelength Switched Optical Network (WSON), while it is known
   as Impairment-Aware Routing and Spectrum Assignment (IA-RSA) for a
   Spectrum Switched Optical Network (SSON).

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