Defines the internal VLD along with additional data which is used in this DF. See notes 1 and 2.

defaultInstantiationLevelID

M

0..1

Identifier

This attribute references the "instantiationLevel" entry which defines the default instantiation level for this DF. It shall be present if there are multiple "instantiationLevel" entries.

instantiationLevel

M

1..N

InstantiationLevel

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

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

affinityOrAntiAffinityGroup

M

0..N

AffinityOrAntiAffinityGroup

Specifies affinity or anti-affinity relationship applicable between the virtualisation containers (e.g. virtual machines) to be created using different VDUs or internal VLs to be created using different VnfVirtualLinkDesc(s) in the same affinity or anti-affinity group. See clause 7.1.8.12.

(See note 3).

scalingAspect

M

0..N
