VDU Data Model (vnfd:vdu)

A VDU is a basic part of VNF. VDUs are virtual machines that host the network function, such as:

• Virtual machine specification

• Computation properties (RAM size, disk size, memory page size, number of CPUs, number of cores per CPU, number of threads per core)

• Storage requirements

• Initiation and termination scripts

• High availability redundancy model

• Scale out/scale in limits

Fields

ID	Type	Cardinality	Description
id	string	1	Unique identifier for the VDU.
name	string	1	Unique name for the VDU.
description	string	1	Description of the VDU.
count	uint64	1	Number of instances of the VDU.
mgmt-vpci	string	1	Specifies the virtual PCI address, expressed in the following format dddd:dd:dd.d. For example 0000:00:12.0. This information can be used to pass as metadata during the VM creation.
vm-flavor	container	1	Flavor of the virtual machine (VM) instance. See vnfd:vm-flavor.
guest-epa	container	1	EPA attributes for the guest operating system. See vnfd:guest-epa.
vswitch-epa	container	1	EPA attributes for Open vSwitch. See vnfd:vswitch-epa.
hypervisor-epa	container	1	EPA attributes for the hypervisor. See vnfd:hypervisor-epa.
host-epa	container	1	EPA attributes for the host operating system. See vnfd:host-epa.
alarm	list	0..n	A list of alarms. See vnfd:alarm.
image-properties	container	1	Image properties, such as name and checksum. See vnfd:image-properties
cloud-init-input	choice	1	Specifies how the contents of cloud-init script are provided. See vnfd:cloud-init-input.
internal-connection-point	list	0..n	List for internal connection points. See vnfd:internal-connection-point.
internal-interface	list	0..n	List of internal interfaces for the VNF. See vnfd:internal-interface.
external-interface	list	0..n	List of external interfaces for the VNF. See vnfd:external-interface.
volumes	list	0..n	List of disk-volumes to be attached to VDU. See vnfd:volumes.
