A YANG Model for Network and VPN Service Performance Monitoring

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 an augmentation to the network topology YANG data model defined in [RFC8345].
