41、 initiated through Ve-Vnfm-em reference point (see clause 7.2.2 of GS NFV-IFA008 4) 1. EM sends to VNFM a CreateVnfIdentifierRequest with parameter vnfdId, vnfInstanceName and vnfInstanceDescription to create a VNF instance identifier (vnfInstanceId) and an associated instance of an NsInfo informati

42、on element (see clause 7.2.2.2 of GS NFV-IFA008 4). 2. VNFM sends to EM a CreateVnfIdentifierResponse with parameter vnfInstanceId identifying the instance identifier of the VNF has been created (see clause 7.2.2.3 of GS NFV-IFA008 4). 3. VNFM sends to EM a Notify (see clause 7.3.3 of GS NFV-IFA008

43、4) carrying VnfIdentifierCreationNotification information element with attribute vnfInstanceId to indicate the VNF instance identifier creation (see clause 9.5.7 of GS NFV-IFA008 4).

44、Figure 4.2.2.1-1 depicts a procedure of VNF instantiation by EM request. It is assumed that EM has subscribed to receive the VNF lifecycle change notification from VNFM. As a result of this procedure, the new VNF instance is not associated to any NS (see NOTE in clause 7.2.3.4 in 4). 1. EM sends Cre

45、ateVnfRequest to VNFM with vnfDescriptorId, vnfInstanceName, and vnfInstanceDescription to create the VNF identifier (see clause 7.2.2 4). EM VNFM 3. Notify 1. CreatesVnfIdentifierRequest 2.

46、 VNFM sends CreateVnfResponse to EM with vnfInstanceId to indicate the creation of a new instance of a VNF information element (see clause 7.2.2.3 4). 3. EM sends InstantiateVnfRequest to VNFM with input parameters, listed in clause 7.2.3.2 4 to instantiate a VNF (see clause 7.2.3 4). 4. VNFM sends

47、InstantiateVnfResponse with lifecycleOperationOccurrenceId to EM (see clause 7.2.3.3 4). 5. VNFM send a Notify (see clause 7.5.3 4), carrying VnfLifecycleChangeNotification information element to EM with attributes vnfInstanceId, status = “start”, operation = “instantiation”, lifeycleOperationOccurr

48、enceId, affectedVnfc, affectedVl, and affectedVirtualStorage to indicate the start of VNF instantiation (see clause 9.5.1 4). 6. VNFM send a Notify (see clause 7.5.3 4), carrying VnfLifecycleChangeNotification information element to EM with attributes vnfInstanceId, status = “result”, operation = “i

49、nstantiation”, lifeycleOperationOccurrenceId, affectedVnfc, affectedVl, and affectedVirtualStorage to indicate the result of VNF instantiation, when the VNF instantiation operation is completed (see clause 9.5.1 4). g28g68g1005g856g3g18g396g286g258g410g286g115g374g296g90g286g395g437g286g400g410g3g1006g856g3g18g396g286g258g410g286g115g374g296g90g286g400g393g381g374g400g286g3g115g69g38g68g1007g856g3g47g374g400g410g258g374g410g349g258g410g286g115g374g296g90g286g395g437g286g400g410g3g1010g856g3g69g381g410g349g296g455g1
