Technical Summary
This document defines a YANG data model for representing an abstract
view of the provider network topology that contains the points from
which its services can be attached (e.g., basic connectivity, VPN,
network slices). Also, the model can be used to retrieve the points
where the services are actually being delivered to customers
(including peer networks).
This document augments the 'ietf-network' data model by adding the
concept of Service Attachment Points (SAPs). The SAPs are the
network reference points to which network services, such as Layer 3
Virtual Private Network (L3VPN) or Layer 2 Virtual Private Network
(L2VPN), can be attached. One or multiple services can be bound to
the same SAP. Both User-Network Interface (UNI) and Network-to-
Network Interface (NNI) are supported in the SAP data model.
Working Group Summary
Went pretty smoothly. No controversy. Some detailed debate
during WGLC, but this seemed to reach consensus.
Document Quality
No one has reported any implementations.
Note that this document is referenced by a TEAS document
(draft-ietf-teas-actn-poi-applicability) which discusses a topic that is
likely to lead to implementation, and by the TEAS network slicing
framework (draft-ietf-teas-ietf-network-slices) which is likely to mean
that YANG models for the network slice service interface (such as
draft-ietf-teas-ietf-network-slice-nbi-yang) may come to use it in time.
