What are the three major blocks of the NFV architecture?
VIM, NFVO, and VNFM
ETSI, MANO, and VNF
NF, NFVI, and MANO
OSS, BSS, and VNF
VNFM is responsible for which of the following?
managing the infrastructure hardware and controlling its allocation to the VNFs
managing the lifecycle of the VNF (instantiation, scaling up or down, termination) as well as FCAPS management of the VNF
deploying the end-to-end service in the NFV architecture
gathering the FCAPS information of the physical hardware from VIM and passing them to NFVO so that the resources can be appropriately managed by the upper layers for the ETSI framework
Which management functional block facilitates running multiple virtual machines/VNFs on the same hardware?
Virtualized Network Function Manager (VNFM)
Virtualization Infrastructure Manager (VIM)
Element Manager (EM)
Network functions virtualization Orchestrator (NFVO)
Communication between different functional blocks such as VIM to VNFM, VNFM to NFVO in the ETSI architecture is called?
