ScalingAspect
The ScalingAspect class describes the details of an aspect used for horizontal scaling.
Applied stereotypes:
- OpenModelClass
- support: MANDATORY
- Reference
- reference: IFA011 v2.5.1
- Experimental
Attribute Name | Type | Mult. | Stereotypes | Description |
id | String | 1 | OpenModelAttribute
Experimental | Unique identifier of this aspect in the VNFD.
|
name | String | 1 | OpenModelAttribute
Experimental | Human readable name of the aspect.
|
description | String | 1 | OpenModelAttribute
Experimental | Human readable description of the aspect.

InstantiationLevel
The InstantiationLevel class describes a given level of resources to be instantiated within a DF in term of the number of VNFC instances to be created from each VDU. All the VDUs referenced in the level shall be part of the corresponding DF and their number shall be within the range (min/max) for this DF.

Attribute Name | Type | Mult. | Stereotypes | Description |
levelId | Identifier | 1 | OpenModelAttribute
Preliminary | Uniquely identifies a level with the DF.
|
description | String | 1 | OpenModelAttribute
Preliminary | Human readable description of the level.
|
scaleInfo | ScaleInfo | 0..* | OpenModelAttribute
Preliminary | Represents for each aspect the scale level that corresponds to this instantiation level. scaleInfo shall be present if the VNF supports scaling.
|
_vduLevel | VduLevel | 1..* | OpenModelAttribute
Preliminary | Indicates the number of instance of this VDU to deploy for this level.
|
virtualLinkBitRateLevel | VirtualLinkBitRateLevel | 0..* | OpenModelAttribute
Preliminary | Specifies bitrate requirements applicable to virtual links created from particular virtual link descriptors for this level. NOTE: If not present, it is assumed that the bitrate requirements can be derived from those specified in the VduCpd instances applicable to the internal VL. If present in both the InstantiationLevel and the VduCpd instances applicable to the internal VL, the highest value takes precedence.
