  • terminateTime

Response

201 Accepted

NsLcmOperationOccurrenceNotification (Start/Processing/Completed)


Design

  • Get an ns_inst_d, job_id and request_data from the parameters
  • if there no matching ns_inst_id from the NFVO_NSINT database table, consider there is nothing to terminate, and return
  • set job status as "Starting terminate..."
  • update the ns_inst_id row from the NFVO_NSINST database table with the status = TERMINATING
  • cancel SFC list
    • get sfc inst array
    • for each sfc inst
      • DELETE /api/nslcm/v1/ns/sfcs/{instId}
  • cancel VNF list
    • get vnf inst list array from NFVO_NFINST
      • for each vnf inst
        • delete_vnf (nf_instid)
          • POST /api/nslcm/v1/ns/terminateVnf/{instId}
  • cancel VL list
    • get VL Inst array
    • for each VL inst
      • DELETE /api/nslcm/v1/ns/vls/{instId}
  • cancel PNF list
    • get pnf inst array
    • for each pnf inst 
      • DELETE /api/nslcm/v1/pnfs/{instId}
  • modify the ns_inst_id row state from the NFVO_NSINST database table
  • modify NFVO_NSINST status = NOT_INSTANTIATED
  • set job status = NS terminate ends
  • Update NsLcmOpOCC to COMPLETED
  • Send nsLcmOperationOccurrenceNotification

Request

  • No; just parameter nsInstanceId


Response

  • 204 No Content

Notification

  • Send NsIdentifierDeletionNotification


Design

  • get ns_inst_id
  • delete ns instance in AAI
    • get ns_instances from NFVO_NSINST database table
    • invoke delete_ns_aai with global_customer_id, service_type, ns_inst_id, resource_version
      • formulate the resource url with parameters
      • call_aaI (resource, "DELETE")
  • delete ns_inst_id row from the NFVO_NSINST database table
  • delete ns_inst_id row from the NFVO_INPutParamMapping database table
  • delete ns_inst_id row from the DefPkgMapping database table
  • delete ns_inst_id row from the ServiceBaseInfo database table
  • return 204 No Content
  • Send NsIdentifierDeletionNotification
