1. High Level Component Definition and Architectural Relationships 


The Configuration Persistence Service (CPS) provides storage for real-time run-time configuration and operational parameters that need to be used by ONAP.

In R7 this will be PoC which is described here: High Level Design (PoC)

In R8, Honolulu, the CPS will be a stand-alone component.

Interface NamePurpose Reason For UseAPI Spec (Swagger)
SDCE-7

This interface is used to receive the service and resource artifacts (CSAR Package) from SDC.

This allows the RunTime C&PS DB to process the design-time Yang model artifacts onboarded.

STEPS:

(1) ONBOARDING - A vendor onboards artifacts describing the parameters supported for their PNFs and VNFs in xNF Package.

(2) SDC CATALOG - The onboarded artifacts are stored in the SDC Catalog after onboarding and validated (VNF-SDK).

(3) CSAR DISTRIBUTION - The contents of the artifacts are distributed by SDC in a CSAR package onto the DMaaP bus.

(4) SETTING UP RUNTIME DB - S/W to setup the RunTime DB using the content of the CSAR package consumes the SDC CSAR Package.
