OpenECOMP includes a generic Application Controller (APPC, sometimes formerly called APP-C) that receives commands from OpenECOMP components, such as MSO, DCAE, or the Portal, and uses these commands to manage the life cycle of Services, Resources (virtual applications and Virtual Network Functions), and their components. The Application Controller is based on the same OpenDaylight Framework with SLI additions. The Application Controller project provides SLI node types, adapters, and API handling logic required for the life cycle management of complex, distributed services composed of many VNF types and instances. See the OpenECOMP Application Controller User Guide and the APPC API page.
