- Scenario 1:
- An external VNFMs registers with ONAP as a SOL003 compliant VNF Manager and is cataloged
- A designer uses SDC to design a new service that references a VNF
- The SDC presents the designer with details from the VNF-D including resource requirements of each of the flavors, the required input parameters and the external connections points
- The designer selects a deployment flavor, provides default values for the input parameters and specifies how the service should terminate the external connection points
- The designer annotates the VNF reference in the service with a reference to one of the cataloged external VNFMs that have previously registered
- The new service is cataloged
- Scenario 2:
- An operator requests a new instance of a service
- ONAP examines the service and determines that it needs to use an external VNFM to manage a VNF in the service
- ONAP determines which resources should be used to instantiate the VNF and issues a SOL003 create VNF instance request to the VNFM referenced in the service.
- The VNFM requests the entire VNF package as provided by the vendor
- The VNFM extracts the manifest file from the VNF package and compares the signed file digests against the computed digest of each file in the package
- The VNFM replies with a VNF instance ID.
- ONAP issues a SOL003 instantiate request of the VNF instance ID
- The VNFM examines the VNF-D and issues a SOL003 grant request to ONAP asking which resources to use
- ONAP replies with references to the appropriate VIM and credentials for accessing that VIM
- The VNFM instantiates the VNF instance according to the VNF-D
- The VNFM replies with status
- Scenario 3:
- Periodically an ONAP policy requests the status of the service instance.
- ONAP determines that a VNF in the service instance is managed by an external VNFM
- ONAP issues a SOL003 query VNF instance request of the referenced VNFM
- The VNFM replies with the status the VNF instance
- Scenario 4:
- ONAP determines that a VNF instance has crossed a overload trigger
- ONAP determines that the VNF instance is controlled by an external VNFM
- ONAP sends a SOL003 scale out request to the VNFM referencing the VNF instance
- The VNFM examines the VNF-D and issues a SOL003 grant request to ONAP asking which resources to use
- ONAP replies with reference the appropriate VIM and credentials for accessing that VIM
- The VNFM scales the VNF instance using the granted resources according to the info in the VNF-D
- The VNFM replies with status
