Abstract

   This document considers the applicability of Abstraction and Control
   of TE Networks (ACTN) architecture to Packet Optical Integration
   (POI)in the context of IP/MPLS and Optical internetworking,
   identifying the YANG data models being defined by the IETF to
   support this deployment architecture as well as specific scenarios
   relevant for Service Providers.

   Existing IETF protocols and data models are identified for each
   multi-layer (packet over optical) scenario with particular focus on
   the MPI (Multi-Domain Service Coordinator to Provisioning Network
   Controllers Interface)in the ACTN architecture.
