Samsung Electronics Huawei CTTC Lancaster University Cisco This document provides YANG data models that describe the performance monitoring parameters and scaling intent mechanisms for TE-tunnels and Virtual Networks (VNs). Their performance monitoring parameters are exposed as the key telemetry data for tunnels and VN. The models presented in this document allow customers to subscribe to and monitor the key performance data of the TE-tunnel or the VN. The models also provide customers with the ability to program autonomic scaling intent mechanisms on the level of TE-tunnel as well as VN.
