    abstract =  {This document defines a YANG data model for representing an abstract view of the provider network topology containing the points from which its services can be attached (e.g., basic connectivity, VPN, network slices). The data model augments the 'ietf-network' data model by adding the concept of service attachment points (SAPs). The service attachment points are the points to which network services (such as L3VPN or L2VPN) can be attached. The customer endpoint of an attachment circuits are not covered in the SAP network topology.},
