String

Human readable description of the aspect.

associatedGroup

M

0..1

Identifier (Reference to VnfdElementGroup)

Reference to the group of Vnfd elements   defining this aspect.

If present, scaling for this aspect is limited   to the elements of the group, but there is no assumption that all the   elements of the groups will be increased at each step. See note 1.

maxScaleLevel

M

1

PositiveInteger

The maximum scaleLevel for total number of   scaling steps that can be applied w.r.t. this aspect. The value of this attribute   corresponds to the number of scaling steps can be applied to this aspect when   scaling it from the minimum scale level (i.e. 0) to the maximum scale level   defined by this attribute. See note 2.

NOTE 1:   In the present   release of the specification, support for modifying the internal VNF topology   during the scaling of the internal VLs, is not required.

NOTE 2:   A scaling step is the smallest increment by   which a VNF can be scaled for a particular aspect. Scaling by a single step does not imply that only one VNFC instance is created or removed. It   means that one or more VNFC instances are   created from the same VDU or from different   VDUs, or that a more complex setup occurs.
