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 defined in RFC
8345 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-to-Network Interface (UNI) and
Network-to-Network Interface (NNI) are supported in the SAP data
model.
This document is a product of the Operations and Management Area Working Group
Working Group of the IETF.
This is now a Proposed Standard.
