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 | 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 | 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). |
| Vnfd | Association | 0..* to 0..* | Preliminary OpenModelAttribute
| Vnfd binds to an NS Virtual Link Descriptor via VNF external CPs. VNF extenrnal CPs are exposed to NSD via VNFD |
Pnfd | Association | 0..* to 0..* | Experimental OpenModelAttribute
