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.
