For the purposes of the present document, the terms given in
TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in
TR 21.905.
Network Functions Virtualisation Infrastructure (NFVI):
totality of all hardware and software components that build up the environment in which VNFs are deployed, as defined in ETSI GS NFV 003 [17].
Network Functions Virtualisation Orchestrator (NFVO):
functional block that manages the Network Service (NS) lifecycle and coordinates the management of NS lifecycle, VNF lifecycle (supported by the VNFM) and NFVI resources (supported by the VIM) to ensure an optimized allocation of the necessary resources and connectivity, as defined in ETSI GS NFV 003 [17].
Virtualised Infrastructure Manager (VIM):
functional block that is responsible for controlling and managing the NFVI compute, storage and network resources, usually within one operator's Infrastructure Domain (e.g. NFVI-PoP), as defined in ETSI GS NFV 003 [17].
Virtual Machine (VM):
virtualised computation environment that behaves very much like a physical computer/server, as defined in ETSI GS NFV 003 [17].
Virtualised Network Function (VNF):
implementation of an NF that can be deployed on a Network Function Virtualisation Infrastructure (NFVI), as defined in ETSI GS NFV 003 [17].
Virtualised Network Function Component (VNFC):
internal component of a VNF providing a VNF Provider a defined sub-set of that VNF's functionality, with the main characteristic that a single instance of this component maps 1:1 against a single Virtualisation Container, as defined in ETSI GS NFV 003 [17].
Virtualised Network Function Component Instance (VNFCI):
instance of a VNFC deployed in a specific Virtualisation Container instance. It has a lifecycle dependency with its parent VNF instance, as defined in ETSI GS NFV 003 [17].
Virtualised Network Function Manager (VNFM):
functional block that is responsible for the lifecycle management of VNF, as defined in ETSI GS NFV 003 [17].
VNF Package:
archive that includes a VNF descriptor, the software image(s) associated with the VNF, as well as additional artefacts, e.g. to check the integrity and to prove the validity of the archive, as defined in ETSI GS NFV 003 [17].
virtualised network product class:
class of products that implement 3GPP defined network functionalities running on Network Function Virtualisation Infrastructure (NFVI).
virtualised network product:
A virtualised network product is the instantiation of one or more virtualised network product class(es).
Void.
