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

For the ETSI package storage, SO does the following:

  • 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.
  1. VF-C Catalog DB Microservice
  • Database: nfvocatalog (vfc-nfvo-catalog-createdb.sql // create db scripts)
  • Database Table (vfc-nfvo-catalog-createobj.sql // create tables scripts)
  • Catalog_NSPackage
  • Catalog_VNFPackage
  • Catalog_PNFPackage
  • Catalog_SoftwareImageModel

2.VF-C Catalog (API) Microservice

  • vfc-catalog docker
  • VFC Catalog REST APIs
    • The following APIs are part of VF-C Swagger REST APIs. For the complete ApIs, https://docs.onap.org/en/latest/_downloads/0fea611e8b07fb4042e1a66ce202898c/CATALOG_API_Specification_v1.json

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 model 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 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.
    • Deployment location of ONAP-ETSI Catalog Manager microservices is under discussion.
    • SO and other ONAP run-time components could leverage the ONAP-ETSI Catalog Manager function, as a common service.

  • ONAP-ETSI 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 POST API will be used to store the VNF packages

SO Catalog Modelling

  • 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.



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

      • Need to pass artifacts (images) to VIM thru the Adapter
      • Get the original vendor VNF package
    • Retrieving VNFD for SOL003 Adapter
    • Retrieving NSD/VNFD for SOL005 Adapter
      • GET /nspackages/{csarId} // query NS package info
      • More SOL005 Adapter requirements are being collected.
