43、 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 information element (see cl

44、ause 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 4) carrying VnfIde

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

46、epicts 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 CreateVnfRequest to V

47、NFM with vnfDescriptorId, vnfInstanceName, and vnfInstanceDescription to create the VNF identifier (see clause 7.2.2 4). 2. 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 InstantiateVnf

48、Request 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 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 info

49、rmation element to EM with attributes vnfInstanceId, status = “start”, operation = “instantiation”, lifeycleOperationOccurrenceId, affectedVnfc, affectedVl, and affectedVirtualStorage to indicate the start of VNF instantiation (see clause 9.5.1 4).
