...

• • Leverage ETSI standards for VNF LCM in SO

  • Build SO VNFM Adapter

    • Use SOL003 APIs (2.5.1) for VNF LCM

    • Support operations such as create, instantiate, grant, query, terminate LCN subscription and LCN

    • Support terminate is a stretch goal

  • Enhance SO BPMN workflows & recipes

    • VNF-level and VF-Module workflows, leveraging VNFM Adapter 

    • Passing VNF LCM requests to VNFM using VNFM Adapter

  • Policy based VNF scale out thru VNFM Adapter (Stretch Goal)

    • VNFM Adapter interfaces for VES event

    • Policy Framework for scaling decisions

    • SO workflows for VNF Scale out

  • Provide VNF package management for VNFM (Stretch Goal; under investigation)

  • VNF-level and VF Module-level Assignment modeling in SDNC and A&AI (open issue)

  • VNF Application Configuration thru VNFM Adapter and VNFM (open issue & not for Dublin)

...

• • A new SO sub-component, following ONAP Microservice Architecture

  • A Generic VNFM Adapter, supporting SOL003-compliant SVNFMs

  • Support of SOL003 APIs for VNFM LCM
    • VNF Package management (Download & Parse VNF Package)
      • Get package files from the SDC repository thru SO
      • Provide VNF package(s), VNFDs and Artifacts to VNFM
      • SO Catalog DB enhancement for SOL001/SOL004 is under discussion, for future release
    • Invoking SVNFM based on SOL003 VNF LCM APIs as a client

      • use https://forge.etsi.org/gitlab/nfv/SOL002-SOL003/2.5.1/master/src/SOL003/VNFLifecycleManagement swagger to generate a client

      • support Create VNF, Instantiate VNF, Query, Terminate VNF operations as a client

      • collect data for SOL003 API parameters from SDNC, A&AI and OOF

    • Granting, based on ETSI VNFLifecycleOperationGranting

      • use https://forge.etsi.org/gitlab/nfv/SOL002-SOL003/tree/master/src/SOL003/VNFLifecycleOperationGranting swagger to generate grant services

      • Grant decisions based on the data from OOF (based on location, inventory data, resource availability, business rules, etc.) and/or VIM registration

    • Subscription to SVNFM for getting notifications
      • STARTING, PROCESSING, COMPLETED
  • SVNFM selection based on configuration values that are configured during VNF on-boarding and VNFM registration. Two methods are considered:
    • Correlation between VNF NF Type and VNFM Type (Nokia method)
    • Utilizing VNFD vnfm_info:type, VNFM registration values: VNFM type, Cloud region, vendor

...

• • Vendor SVNFM must be "SOL003-compliant"
  • Providing SOL003 APIs for VNFM LCM, based on ETSI VNFLifecycleManagement
    • Use https://forge.etsi.org/gitlab/nfv/SOL002-SOL003/2.5.1/master/src/SOL003/VNFLifecycleManagement swagger for providing services
    • Create
    • Instantiate
    • Query
    • Grant request to SO VNFM Adapter, as a client
    • Life cycle notification
    • Terminate
  • Registration itself to ONAP (thru A&AI ESR) - Name, Type, Vendor, Version, URL, VIM, Username and Password
  • Providing Subscription Services for Life-cycle Management Notifications
  • Support of the "Direct Mode" of Resource Management only
    • After receiving a grant permission, the VNFM sends requests for resources directly to VIM
    • Invoking MultiCloud from VNFM is under discussion, but not for Dublin
    • The "Indirect Mode" of Resource Management is being discussed, but not for Dublin

...

• VNFM Adapter Sub-components

  
  

  

  • 
    
    • SO VNFM Adapter component is a sub component of SO; utilizing docker image and container manged.
    • North Bound Interface (NBI)
      • RESTful APIs that support createVnf, instantiateVnf, queryVnf, grantVnf, TerminateVnf
      • Its APIs are SO specific; i.e., not SOL003-based ones
    • Business Logic layer
      • It is invoked by the NBI and provides business logic for createVnf, instantiateVnf, queryVnf, terminateVnf
      • SDNC and A&AI access to collect assignment and VimConnectionInfo
      • Accesses SdcPackageProvider for getting SOL003 package(s) and parameters
      • SdcPackageProvider
        • Supports SOL001/SOL004 package management
        • Provides getPackage, getVnfdId, getFlavorId, getVnfNodeProperty
        • Provides getPackage(s), getVnfd, getArtifactFile for SVNFM
        • Uses SDC Tosca Parser
      • GrantManager
        • Provides requestGrantForInstantiate REST API for SVNFM
        • Invokes OOF for homing decision; HPA support, and/or non-OOF decision
      • SOL003Lcn APIs
        • Supports VnfIdentifierCreationNotification, VnfIdentifierDeletionNotification, VnfLcmOperationOccurrenceNotification
    • SOL003 Communication Layer
      • It is a thin REST client layer, which sends SOL003-compliant requests to SVNFMs and receives responses/notifications from SVNFM.
      • For Grant, it provides the Grant REST endpoint for SVNFMs.
