Abstract

   This document considers the applicability of ACTN to Packet Optical
   Integration (POI) and IP and Optical DWDM domain internetworking,
   and specifically the YANG models being defined by the IETF to
   support this deployment architecture.

   In this document we highlight the IETF protocols and 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 Packet Optical Integration
   (POI) use cases.
