Applicability of Abstraction and Control of Traffic Engineered Networks (ACTN) to Packet Optical Integration (POI)

This document explores the applicability of the Abstraction and Control of TE Networks (ACTN) architecture to Packet Optical Integration (POI) within the context of IP/MPLS and optical internetworking. It examines the YANG data models defined by the IETF that enable an ACTN-based deployment architecture and highlights specific scenarios pertinent to Service Providers. Existing IETF protocols and data models are identified for each multi-technology scenario (packet over optical), particularly emphasising the Multi-Domain Service Coordinator to Provisioning Network Controller Interface (MPI) within the ACTN architecture
