    A YANG Model for Network and VPN Service Performance Monitoring
                draft-ietf-opsawg-yang-vpn-service-pm-00

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 document does not define metrics for network performance or
   mechanisms for measuring network performance.  The YANG model defined
   in this document is designed as an augmentation to the network
   topology YANG model defined in RFC 8345 and draws on relevant YANG
   types defined in RFC 6991, RFC 8299, RFC 8345, and RFC 8532.
