Abstract

   This document considers the applicability of the IETF Abstraction
   and Control of Traffic Engineered Networks (ACTN) to Packet Optical
   Integration (POI), and IP and Optical DWDM domain internetworking.

   In this document, we highlight the IETF protocols and YANG data
   models that may be used for the ACTN and control of POI networks,
   with particular focus on the interfaces between the MDSC (Multi-
   Domain Service Coordinator) and the underlying Packet and Optical
   Domain Controllers (P-PNC and O-PNC) to support POI use cases.
