(VirtualCpu)

This references (couples) the CPD with any logical node I/O requirements (for network devices) that may have been created. Linking these attributes is necessary so that so that I/O requirements that need to be articulated at the logical node level can be associated with the network interface requirements associated with the CPD.

virtualLinkDescId

Identifier

1

Unique identifier of this internal VLD in VNFD.

flavorId

Identifier

1

Identifier of this DF within the VNFD.

Defines the internal VLD along with additional data which is used in this DF.

NOTE 1: This allows for different VNF internal topologies between DFs.

NOTE 2: virtualLinkProfile needs to be provided for all VLs that the CPs of the VDUs in the VDU profiles connect to.

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

Examples: Small, Medium, Large.

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

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.

NOTE: In the present specification, including either VDU(s) or VnfVirtualLinkDesc(s) into the same affinity or anti-affinity group is supported. Extension to support including both VDU(s) and VnfVirtualLinkDesc(s) into the same affinity or anti-affinity group is left for future specification.

Identifier(s) of the affinity or anti-affinity group(s) the VnfVirtualLinkDesc belongs to.
