Feature Descriptions

SO ETSI Catalog DB Support for NS, VNF and PNF Packages

...

• SO (SDC Controller component) queries the package from SDC
• SO stores ETSI (including SDC AID DM) + vendor VNF package CSAR or ZIP
  • If the onboarding vendor package is a zip file with signature and certificate, SO stores the vendor VNF package as a zip format.
  • Not all VNFD needs to be transformed to the SDC AID DM - TBD
• For Non-ETSI models (Service + Non-ETSI Resource), SO will use the existing SO embedded Catalog DB

Instead of building ONAP-ETSI Catalog management in SO, SO will leverage the existing ONAP-ETSI Catalog Manager function.

• Use VF-C Catalog Microservices for the NS, VNF and PNF catalog support, https://wiki.onap.org/pages/viewpage.action?pageId=63996543
  • VFC Catalog Manager function consists of two microservices: VF-C DB and VF-C Catalog. Deployment of these microservices is independent of VF-C, and the microservices have no dependency on other VF-C components – a good stepping stone towards common ONAP-ETSI Catalog management
  • VFC Catalog Manager will be enhanced to handle the vendor package in the ONBOARDING_PACKAGE directory.

...

The following diagram depicts a possible ONAP-ETSI Catalog DB handling for NS, VNF and PNF Packages.

• SDC Stores Service models/templates into the existing SO Catalog DB, and ETSI Catalog will be stored in the ONAP-ETSI Catalog Manager database. 
• Note: the ONAP-ETSI Catalog Manager function could be realized by the VFC (or equivalent) ONAP-ETSI Catalog API and ETSi ONAP-ETSI Catalog DB Microservices - To be discussed further.
  • VF-C DB and Catalog are two Microservices, which they can be deployed independently from VF-C, and they don't have dependency with other VF-C components.
  • SO and other ONAP run-time components could leverage the ONAP-ETSI Catalog Manager function, as a common service.

• ONAP-ETSI Catalog Manager Catalog Manager Interfaces
  • Supports its NBI for create and update ONAP-ETSI catalog. SDC Controller will uses the NBI.
  • Retrieves model artifact files from SDC
  • Stores the data to the ONAP-ETSI Catalog DB.
  • Supports its Query operations for SOL003/SOL005 Adapters

SO Package Management ( SDC - SO SDC Controller - ONAP-ETSI Catalog Manager)

• SO SDC Controller module (ASDCController and ToscaResourceInstall) needs to be updated for handling SOL004 packages including SOL001 VNFD and PNFD.
• Service-level catalog and other non-ETSI catalog (SDC AID DM) will be stored in SO Catalog DB.
• VNF/PNF/NS-level catalog handling would be simplified:
  • By using the ONAP-ETSI Catalog Manager, ETSI VNF/PNF/NS-level catalogs (i.e., original vendor packages) will be stored in ONAP-ETSI Catalog DB
  • SO itself does not need to manage ETSI-based VNF LCM; i.e., delegates the LCM to VNFM through the SOL003 VNFM Adapter
• In Frankfurt, VNF package management will be supported.
• The following diagram depicts the component interactions for VNF Package store for ONAP runtime.

...

• Interfaces between SDC Controller and ONAP-ETSI Catalog Manager

• ONAP-ETSI Catalog Manager Catalog Manager POST API will be used to store the VNF packages
  • POST /api/catalog/v1/vnfpackages // passing csarId, vimIds and labVimId

...

<describe relationship/association between the existing SO catalog database (service catalog, VNF catalog , Vnf_Resource_customization) and the ONAP-ETSI Catalog database > 

• Q&A:
  • How does VFC handle VNF packages from SDC? Does it use SDC AID DM? Does it use VF-Modules?
  • Answer:
    • VF-C supports SDC internal models with the original vendor package and ETSI-based VNF package
    • Currently, no VF-Module support from VF-C and SOL003 VNFM Adapter
    • VF-Module mapping and handling need to be sorted out.

...

• The service database table has TOSCA_CSAR_ARTIFACT_UUID column. We continue to use this column to link the TOSCA CSAR.
• The TOSCA_CSAR database has a logical relationship with Catalog_NSPackage, Catalog_PNFPackage and Catalog_VNFPackage.
  • When a record is entered in the TOSCA_CSAR,
    • if the CSAR artifact type is NS, add a NS package into Catalog_NSPackage
    • if the CSAR artifact type is VNF, add a VNF package into Catalog_VNFPackage
    • if the CSAR artifact type is PNF, add a PNF package into Catalog_NSPackage
• For the SOL004 VNF onboarding into SO,
  • SO does not populate data info the VF-Module database table if the VF-Module is not populated in the modeling.
    • It depends on the SOL001 VNFD mapping to SDC AID DM whether it populates VF-Modules or not.
  • SO does not populate data into the HEAT-Template database table
    • Heat-Template is part of the VNF package
  • SO invokes the ONAP-ETSI Catalog Manager APIs with the CSAR UUID.
    • ToscaResourceInstaller (InstallTheVfResource, InstallThePNFResource) will be modified to invoke the ONAP-ETSI Catalog Manager.
    • Note: the NS use case needs to be defined since SDC does not support SOL007 (NS Package) yet.
  • The ONAP-ETSI Catalog Manager receives VNF packages and stores them into the ONAP-ETSI Catalog Database Catalog_VNFPackage
    • It stores the VNF package as a whole and its APIs can extract the VNFD, artifacts, softwareImage, etc.

...

• SO Catalog models and relationships are as follows:
  • Note: the relationship between TOSCA_CSAR and Catalog_NSPackage/Catalog_VNFPackage/Catalog_PNFPackage is logical since the Catalog_***Package will be resided in the ONAP-ETSI Catalog DB.

Catalog Manager - SOL003/SOL005 Adapter

As the diagram depicts, ETSI Catalog Manager consists of two microservices:

• ONAP-ETSI Catalog API
• ONAP-ETSI Catalog DB

• Interfaces between ONAP-ETSI Catalog Manager and SOL003/SOL005 Adapters

• ONAP-ETSI Catalog Manager Catalog Manager provides RESTful services to Adapters:
  • ETSI package management for the Adapters.
    • GET /api/catalog/v1/vnfpackages/{csarId}
