RunTime DB:

1 High Level Component Definition and Architectural Relationships 



The RunTime DB function provides storage for real-time run-time parameters that need to be used by ONAP. It provides

PURPOSE:

  • Run-Time data storage repository for: (1) configuration parameters used by xNFs in run time and (2) operational parameters used by ONAP and xNFs.

  • It is designed to be a common services data layer which can serve as a data lake.
  • Enables sync data with xNFs. (source of truth, sync data, restore/initialize). Can be used for xNF crash restoration, history management and auditing.
  • Enables OSS configuration, optimization, and LCM operations.

ACCESS:

  • Run-Time parameters can be READ by any ONAP platform component and any plug-in.

  • Parameters can be READ/WRITE from Controllers, DCAE/DMaaP, A&AI and other components with permission settings.

  • SO, DCAE, A&AI, Controllers (CDS, APPC, SDNC) will have default read/write access to RunTime DB
  • Other components will have default read-only access to RunTime DB but can be given access on a per record basis.

INDEXING & SYNCING:

  • Software keeps the A&AI elements with the elements in the RunTime DB in Sync. 

  • A&AI is still the master of valid entities in the network and provides a dynamic view of the assets (xNFs) available to ONAP
  • The RunTime DB is a master of the associate (exo-inventory) data associated with the entities.
  • When a xNF appears or is removed from the system, RunTime DB records will be added/removed based on A&AI entries.
  • Data Records will be indexed by xNF (VNF, PNF, ANF).

2. API definitions

RunTime DB provides the following interfaces:

Interface NameInterface Definition Interface CapabilitiesVersionStatusConsumed Models
RTDBE-1RunTime DB Interface. 

An interface to create, update, retrieve, query, delete information from the RunTime DB.

ACCESS:

 - SO, DCAE, A&AI, Controllers (CDS, APPC, SDNC) will have default read/write access to RunTime DB

 - Other components will have default read-only access to RunTime DB but can be given access on a per record basis.




RTDBE-2RunTime DB Graphical User Interfaces Provides the capability to view and edit the data currently in the RunTime DB.


Note:   xxxI interface is a Component internal interface.  xxxxE interface is a component external interface

RTDB consumes the following Interfaces:

Interface NamePurpose Reason For Use
SDCE-7

To receive the service and resource artifacts from SDC.

STEPS:

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

(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 using the content of the CSAR package consumes the SDC CSAR Package.
