    • Terminate VNF

      • HTTP Method Type: POST

      • VNFM Endpoint: /vnf_instances/{vnfInstanceId}/terminate

      • Request Payload: TerminateVnfRequest

      • Response Header: 202 success

      • Response Body: not applicable

      • Design
        • VNF precondition = INSTANTIATED state
        • After the operation, VNF state = NOT_INSTANTIATED 
        • VNFM Adapter sends a POST request to the Task resource that represents the lifecycle operation to be executed on the VNF instance, and includes in the payload body a data structure of type TerminateVNFRequest (VNFM Adapter → VNFM); POST ../vnf_instances/{vnfInstanceId}/terminate
        • VNFM Creates a "VNF LCM operation occurrence" resource for the request (VNFM → VNFM Adapter)
        • VNFM returns a "202 Accepted" response with an empty payload body and a "Location" HTTP header that points to the new "VNF LCM operation occurrence" resource (VNFM → VNFM Adapter); .../vnf_lcm_op_occs/{vnfLcmOpOccId}
        • VNFM sends to the VNFM Adapter a VNF lifecycle management operation occurrence notification to indicate the start of the lifecycle management operation occurrence with the "STARTING" state
        • VNFM and VNFM Adapter exchange granting information (see Granting section)
        • VNFM sends to the VNFM Adapter a VNF lifecycle management operation occurrence notification to indicate that the VNF LCM operation occurrence enters the "PROCESSING" state
        • VNFM Adapter polls the "VNF LCM operation occurrence" resource to obtain information about the ongoing operation by sending a GET request to the resource that represents the VNF LCM operation occurrence.
        • VNFM returns to the VNFM Adapter information of the operation, such as the operation status, by providing in the payload body a data structure of type "VnfLcmOpOcc"
        • VNFM has finished the operation <<Operation>>
        • VNFM sends a VNF lifecycle management operation occurrence notification to VNFM Adapter to indicate the completion of the lifecycle management operation occurrence with the success state "COMPLETED"
        • Note: its communication exchange pattern is the same as the Instantiate VNF.

• • • Delete VNF (Stretch Goal in Dublin)

      • HTTP Method Type: DELETE

      • VNFM Endpoint: /vnf_instances/{vnfInstanceId}

      • Request Payload: not applicable

      • Response Header: 204 success

      • Response Body: not applicable

...

• • • • • VNF precondition = NOT_INSTANTIATED

        • After the operation, VNF resource has been removed from the list of VNF instance resources

        • VNFM Adapter sends a DELETE request to the "Individual VNF Instance" resource.
        • The VNFM deletes the VNF instance resource and the associated VNF instance identifier.
        • The VNFM returns a "204 No Content" response with an empty payload body.
        • The VNFM sends to the VNFM Adapter a VnfIdentifierDeletionNotification to indicate the deletion of the VNF instance resource and the associated VNF instance identifier.
        • If the VNF instance is not in NOT_INSTANTIATED state, the VNFM rejects the deletion request.
