1. REGISTER for distribution – SO, DCAE, A&AI, SDN-C, APP-C, VF-C register for distribution of the SDC Artifact distribution via the registration service of the SDCE-6 interface. 
   Note: This is only done once, not once per distribution request.

2. CSAR Ready NOTIFICATION to Consumer– SDC informs the consumer that there is a new artifact to be distributed using the Distrbution notification interface of SDCE-6.

3. CSAR RETRIEVAL request: The cosumer requests to retrieves the artifact using the Artifact retrieval interface of SDCE-6, indicating the required Artifact Type.

4. CSAR DELIVERY: As a response to (3) SDC delivers the artifact to the consumer using SDCE-6 
5. STORE CSAR:  The Consumer stores the distributed artifact.
6. Consumer Status Update- The consumer informs SDC that the artifact has been consumed using the distribution status interface of SDCE-6.
7. Unregister from CSAR distribution. At any time, any module can unregister from the reception of the CSAR using the Register for distribution service of SDCE-6 interface.
   Note: This is only done if the Consumer does not want to be informed of any more artifacts that are ready to distribute
