1. Introduction
Normally network connectivity services are discussed as a means to
inter-connect various abstract or physical network topological
elements, such as ports, link termination points and nodes
[I-D.ietf-teas-yang-te-topo] [I-D.ietf-teas-yang-te]. However, the
connectivity services, strictly speaking, interconnect not the
network topology elements per-se, rather, located on/associated with
the various network and service functions [RFC7498] [RFC7665]. In
