    abstract =  {The data model for network topologies defined in RFC 8345 introduces vertical layering relationships between networks that can be augmented to cover network and service topologies. This document defines a YANG module for performance monitoring (PM) of both networks and VPN services that can be used to monitor and manage network performance on the topology at higher layer or the service topology between VPN sites.},
