Identifier(s) of the affinity or anti-affinity group(s) the VDU belongs to.

NOTE: Each identifier references an affinity or anti-affinity group which expresses affinity or anti-affinity relationships between the virtualisation container(s) (e.g. virtual machine(s)) to be created using this VDU and the virtualisation container(s) (e.g. virtual machine(s)) to be created using other VDU(s) in the same group.

Unique identifier of this internal VLD in VNFD.

flavorId

Identifier

1

Identifier of this DF within the VNFD.

Defines the internal VLD along with additional data which is used in this DF.

NOTE 1: This allows for different VNF internal topologies between DFs.

NOTE 2: virtualLinkProfile needs to be provided for all VLs that the CPs of the VDUs in the VDU profiles connect to.

Describes the various levels of resources that can be used to instantiate the VNF using this flavour.

Examples: Small, Medium, Large.

If there is only one "instantiationLevel" entry, it shall be treated as the default instantiation level for this DF.

levelId

Identifier

1

Uniquely identifies a level with the DF.

Specifies bitrate requirements applicable to virtual links created from particular virtual link descriptors for this level.
