Use Case

To manage vendor-provided VNFs and VIMs, ONAP wants to leverage the vendor-supplied VNFMs. For that, ONAP SO in Dublin added a plug-in capability for SVNFMs and interfaces with the plugged SVNFMs through SOL003 API standards, along with SOL004 VNF packages which include SOL001 VNFD. The SOL003 Adapter in Dublin supported the SOL003 Create, Instantiate, Terminate and Delete operations with Granting, Subscription and Notification. In the Guilin release, the additional SOL003 operations will be supported as follows. For the SOL004 and SOL001 support, see the ETSI Package Management section (ETSI Package Management).

  • Package Management for SVNFM
  • Granting Enhancement with HPA
  • Query
  • Modify (TBD)
  • Policy-based Scaling (Stretch goal)
  • Security between the Adapter and VNFMs
  • Additional operations will be determined

SOL003 VNFM Adapter exposes its NBI to any VNFM Adapter Client. 

  • VNFM Adapter will be part of SO microservices, but the adapter can be invoked thru MSB.
  • It is a stepping stone for GNFC to leverage the VNFM Adapter
  • Supports additional NBI operations for the additional SOL003-based SBI
  • Support secured communication protocol and authentication and authorization via AAF

...

SOL003 Adapter package management support based on SOL003 APIs

  • Handle SOL003-based VNF package requests from SVNFMs
  • Query VNF packages from the ONAP-ETSI Catalog Manager
  • Provide VNF packages to SVNFMs

...

Support of additional SOL003 operations, such as Grant enhancement, Query, Modify, Scale, Operation Status, FM, PM, Heal, VNF Indicator, Retry, Rollback, Failing, Cancelling, Resource Quota Available Notification

  • operation selections and priorities will be determined 

...

The VNFM Adapter needs to handle mapping between SOL001 VNFD and SDC AID DM

  • Not all VNFD needs to be transformed to the SDC AID DM
  • The Adapter will map the model as much as it needs
  • Mapping to the VF-Module is questionable at this time 

...

Policy-based Scaling with VNF Indicator and VES event handling

  • Currently, SOL001 specifications does not support the VNF indicator configuration. As a result, VNFD-based VNF indicator is not supported; i.e., auto scaling is not yet supported
  • Mapping between VF-Module and ScalingAspect+Data is under discussion. Several VNF vendors indicated that they don't want to handle the VF-Module level.

Support of ETSI SOL003 v2.7.1 Or-Vnfm Interface from ONAP to external VNF Manager(s)










Support of ETSI SOL003 v2.7.1 Or-Vnfm Interface from ONAP to external VNF Manager(s)

Executive Summary - Provide an interface adapter from ONAP Service Orchestrator to external VNF Manager(s) using  ETSI SOL003 v2.7.1 (Link to ETSI SOL003 v2.7.1) compliant Interface 

  • Support for Create, Instantiate, Query of a VNF using an external VNF Manager

  • Support for Grant request from an external VNF Manager

  • Support for ModifyVnfInfo using an external Manager

  • Support for VNF Heal

  • Support for VNF Scale (out, in, level)

nameSOL003 Adapter Architecture for Guilin
pagePin2



  1. SOL003 Adapter continues to be an SO microservice component, and exposes its NBI to any SOL003 Adapter client in ONAP
  2. SOL003 Adapter is registered to MSB.
  3. Operator registers VNFM and VIM to ESR in AAI.
  4. SOL003 Adapter exposes its NBI to any SOL003 Adapter client in ONAP
    1. Interfaces will be refactored to be generic to allow access by other ONAP components.
    2. The NBI will be enhanced for additional SOL003 operation support
  5. SDC distributes SDC packages including the vendor original SOL004 (VNF and PNF) and SOL007 (NS) packages 
  6. SO (SDC Controller) passes the SDC CSAR ID to ETSI Catalog Manager to invoke storage
  7. ETSI Catalog Manager queries for SDC CSAR with the SDC CSAR id & store SOL004/SOL007 package.
  8. SO (BPMN) and the SOL003 Adapter client locates SOL003 Adapter.
  9. SO (BPMN) and the SOL003 Adapter client invokes SOL003 Adapter.
  10. SOL003 Adapter retrieves VNF package from Catalog Manager.
  11. SOL003 Adapter gets available VNFM locations (endpoints) and gets VIM and VNF Info.
  12. SOL003 Adapter selects a VNFM, based on a VNFM locating mechanism.
  13. SOL003 Adapter and SVNFM supports SOL003 VNF LCM, granting and package management operations.
  14. SOL003 Adapter supports HPA-based Granting, leveraging OOF.
  15. SOL003 Adapter updates vServer, status and VNF association in AAI
  16. SOL003 Adapter and SVNFM support authentication and authorization (AAF, and vendor AA mechanism) 
  17. For integration testing, the VNFM Simulator is used.
