Orchestration status of this VNF, mastered by APP-C ipaddress-v4-oam-vip Xu: Is this attribute mandatory? and applicable for all kinds of VNFCs?

VNFC Design Time Model
...
Describes network connectivity between a VNFC instance (based on this Vdu) and an internal Virtual Link (VL).
...
Describes CPU, Memory and acceleration requirements of the Virtualisation Container realising this Vdu.
...
Describes storage requirements for a VirtualStorage instance attached to the virtualisation container created from virtualComputeDesc defined for this Vdu.
...
The key indicates the boot index (lowest index defines highest boot priority). The Value references a descriptor from which a valid boot device is created e.g. VirtualStorageDesc from which a VirtualStorage instance is created.
...
Describes constraints on the NFVI for the VNFC instance(s) created from this Vdu.
...
Defines the virtualised resources monitoring parameters on VDU level.
...
Describes the configurable properties of all VNFC instances based on this VDU.
...
Specifies affinity or anti-affinity rules applicable between the virtualisation containers (e.g. virtual machines) to be created based on this VDU.
...
Identifier(s) of the affinity or anti-affinity group(s) the VDU belongs to.

"Y" indicates operator-supplied VNF instance target deployment node required. Present prompt to operator: "Enter target node for deployment of this VNF instance"

"Y" indicates operator-supplied VNF name required. Present prompt to operator: "Enter the name for this VNF instance"
...
Software version of the VNF. This is changed when there is any change to the software that is included in the VNF
Package.
...
Name to identify the VNF Product. Invariant for the VNF Product lifetime.
...
Identifier of the specific VNF Package on which the VNF is based.
...
Possible values: NOT_INSTANTIATED (VNF instance is terminated or not instantiated, and the identifier of the VNF instance exists), INSTANTIATED (VNF instance is instantiated).
...
Information specific to an instantiated VNF instance. Shall be present if the VNF is in INSTANTIATED instantiation state.
...
Additional VNF-specific metadata describing the VNF instance.
...
VNF-specific attributes that affect the lifecycle management of this VNF instance by the VNFM, or the lifecycle management scripts.
...
VNF Design Time Model
...
Human readable name for the VNF Product. Can change during the VNF Product lifetime.
...
Software version of the VNF. This is changed when there is any change to the
software that is included in the VNF Package.
...
Identifies VNFM(s) compatible with the VNF described in this version of the
VNFD.
...
Information about localization languages of the VNF (includes e.g. strings in the
VNFD).
...
Defines descriptors of virtual compute resources to be used by the VNF.
...
Defines descriptors of virtual storage resources to be used by the VNF.
...
Represents the type of network connectivity mandated by the VNF provider between two or more CPs which includes at least one internal CP.
...
Describes external interface(s) exposed by this VNF enabling connection with a VL.
...
Describes specific DF(s) of a VNF with specific requirements for capacity and
performance.
...
Describes the configurable properties of the VNF (e.g. related to auto scaling and
auto healing).
...
Describes the modifiable attributes of the VNF.
...
Includes a list of events and corresponding management scripts performed for the VNF.
...
Describes the associated elements (i.e. VDUs and/or VLs) of a VNFD for a certain purpose during VNF lifecycle management.
...
Declares the VNF indicators that are supported by this VNF.
...
Rule that determines when a scaling action needs to be triggered on a VNF
instance e.g. based on certain VNF indicator values or VNF indicator value
changes or a combination of VNF indicator value(s) and monitoring parameter(s).
