    A YANG Model for Network and VPN Service Performance Monitoring
                 draft-www-bess-yang-vpn-service-pm-06

Abstract

   The data model defined in RFC8345 introduces vertical layering
   relationships between networks that can be augmented to cover
   network/service topologies.  This document defines a YANG model for
   both Network Performance Monitoring and VPN Service Performance
   Monitoring that can be used to monitor and manage network performance
   on the topology at higher layer or the service topology between VPN
   sites.

   This model is designed as an augmentation to the network topology
   YANG data model defined in RFC8345.
