Operator defines service using YANG model
The Cisco NSO workflow starts with the operator defining a service in YANG model. Then NSO maps the service to device configurations using a service template. Next, NSO pushes the configuration to network devices via NETCONF. After that, NSO updates the service database with the operational state. Finally, NSO verifies the service by checking device state and alarms.
