SVNFM Simulator

For integration testing in ONAP, vendor-neutral SVNFM is needed, 

This SVNFM Simulator supports SOL003-based interfaces and message exchange sequences for interface verification.

  • vCPE VNF packages plan to be used for this validation testing.

nameSO VNFM Adapter High Level Flow Design

    1. SO BPMN Service workflows dispatch new resource-level workflows based on VNF request parameters (e.g., type, others).
      1. Once a Service workflow chooses a new workflow path for VNFM Adapter, the subsequent requests for the same VNF will follow the new path.
      2. an association between VNF and VNFM will be made in A&AI.
    2. SO BPMN VNF-level resource workflows handle:
      1. Assign VNF to SDNC
      2. Retrieve the VNF Assignment from SDNC
      3. Invoke VNFM Adapter Client with required parameters
    3. VNFM Adapter Client manages:
      1. Populate parameter structures based on data from SO workflows
      2. Invoke VNFM Adapter NBI with required parameters
    4. VNFM Adapter gets GenericVNF from A&AI
    5. VNFM Adapter locates the corresponding VNF and VNFM registration info form A&AI (ESR). Two methods are suggested
      1. Current one: based on VNF NF Type and VNFM Type in A&AI
      2. Could use VNFD vnfm_info:type, VNFM registration values: VNFM type, Cloud Region, vendor - logic is being designed
    6. VNFM Adapter gets VimConnectionInfo from A&AI
      1. Queries A&AI based on the cloud region and tenant id
      2. Builds the VimConnectionInfo based on the type, service-url, user-name, password, cloud-domain, etc.
    7. VNFM Adapter uses network assignment (e.g., IP Address) from SO (thru SDNC) and builds the extVirtualLinks and other parameters.
