Application Controllers

Application controllers, such as APPC,  receive orchestrated requests from the MSO, which obtains application-specific components and attributes from SDC.  The MSO continues to be responsible for ensuring that the Application Controller successfully completes its Resource configuration as defined by the workflow.

OpenECOMP includes a generic Application Controller (APPC, sometimes 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. See 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.
