Intelligent auto Homing
-----------------------

The following describes the processing flow of the Intelligent Auto Homing.

   :align: center

* 1. NF instantiate request is generated.
* 2. Policies are queried from the OSS/BSS.
* 3-4. NFO checks for the constraints and requirements related to NF.
* 5-10. [Intelligent homing decision]NFO request homing suggestion from
  Non-RT RIC, RIC return with recommended clusterID where the NF can be deployed.
* 11-14. NFO queries the O-cloud inventory status on the base of which homing
  decision in taken by NFO.
* 15-19. DMS sends NF deployment request to the O-Cloud DMS. Instantiation of CNF/Helm
  install is done with health check probes.

Intelligent auto Healing
------------------------

The following describes the processing flow of the Intelligent Auto Healing.

.. image:: /_static/intelligent_auto_healing.png
   :align: center

* 1-2. : DMS received fault performance data and generate alarmevent.
* 3-4. DMS checks for subscriber for the event and send notification in a
  subscriber is available.
* 5-6. DMS detects healing condition for auto healing and then send LCM starting
  notification to the NFO.
* 7-12. DMS confirms healing action and sends grant request to NFO, for intelligent
  homing/placement non-RT RIC does analysis based upon operational policies.
* 13-16. DMS sends LCM operation processing notification to NFO and starts NF
  deployment. Once auto healing is complete, LCM operation Completed
  notification is sent to NFO.
* 17. Once the healing is done DMS sends alarm clear notification to the subscriber.
