Attribute Name | Type | Mult. | Stereotypes | Description |
vitualLinkDescProvider | String | 0..1 | Preliminary OpenModelAttribute
| Defines the organization generating the VLD.
|
virtuaLinkDescVersion | Version | 1 | Preliminary OpenModelAttribute
| Specifies the version of the VLD.
|
virtualLinkDf | VirtualLinkDf | 1..* | Preliminary OpenModelAttribute
| Specifies properties for instantiating a VL according to a specific flavour.
|
virtualLinkDescId | Identifier | 1 | Preliminary OpenModelAttribute
| Uniquely identifies a VLD in the parent descriptor. For VnfVirtualLinkDesc, the parent descriptor is the VNFD. For NsVirtualLinkDesc, the parent descriptor is the NSD. Note: the description of this class are different in ETSI GS NFV IFA 011 and ETSI GS NFV IFA 014. The present definition merges the 2 definitions.
|
connectivityType | ConnectivityType | 1 | Preliminary OpenModelAttribute
| Specifies the protocol exposed by a VL and the flow pattern supported by the VL.
|
description | String | 0..1 | Preliminary OpenModelAttribute
| Provides human-readable information on the purpose of the VL (e.g. control plane traffic). |
