Building Block based PNF PnP flows
==================================
.. image:: ../../images/proposed_building_blocks.png
AssignPnfBB
-----------
* Responsibility:
* Creates PNF entry in AAI (with PNF name chosen by user)
* Additionally stores PNF model-related parameters in AAI:
* model-customization-id
* model-invariant-id
* model-version-id
* Makes a link in AAI between Service entry and PNF entry
* Sets PNF orchestration status in AAI to Assigned
* Currently implemented in CreateAndActivatePnfResource.bpmn
WaitForPnfReadyBB
-----------------
* Responsibility:
* Waits for "PNF ready" event sent from PRH to DMaaP
* pnfCorrelationId from the event must match PNF instance name provided by the user during service instantiation
* Sets PNF orchestration status in AAI to:
* Register - when starting to wait for PNF ready event
* Registered - when PNF ready event is successfully received
* Currently implemented in CreateAndActivatePnfResource.bpmn
Support for config assign (ControllerExecutionBB, action: configAssign)
-----------------------------------------------------------------------
* Responsibility:
* Runs config assign via CDS
* Currently implemented in ConfigurePnfResource.bpmn
* We will reuse generic BPMN for calling CDS (ControllerExecutionBB)
* Things to consider:
* SkipPostInstantiationConfiguration should be taken into account
Support for config deploy (ControllerExecutionBB, action: configDeploy)
-----------------------------------------------------------------------
* Responsibility:
* Runs config deploy via CDS
* Currently implemented in ConfigurePnfResource.bpmn
* We will reuse generic BPMN for calling CDS (ControllerExecutionBB)
* Things to consider:
* SkipPostInstantiationConfiguration should be taken into account
ActivatePnfBB
-------------
* Responsibility:
* Sets PNF orchestration status in AAI as Active
