Class Definition
----------------

BaseConfigGroup
~~~~~~~~~~~~~~~

Every Vnf contains a BaseConfigGroup. BaseConfigGroup may set Access
Control Lists (ACL's) and establish security groups and server groups.
BaseConfigGroup reates/establishs storage for the VM's (OpenStack
Cinder). BaseConfigGroup may establish internal networks such as OAM
(VNF Mgmt) or MNS (Maintenance & Surveillance) established. A very
simple VNF may only have a BaseConfig VnfElementGroup.

**Parent class:** VnfdElementGroup

Applied stereotypes:

-  Experimental

-  OpenModelClass

-  support: MANDATORY

DeploymentGroup
~~~~~~~~~~~~~~~

DeploymentGroup provides the minimum viable VDU and associated VNFC
configuration for a useable VNF. I can have a small, medium, large
deployment configuration.

**Parent class:** VnfdElementGroup

Applied stereotypes:

-  Experimental

-  OpenModelClass

-  support: MANDATORY

HomingGroup
~~~~~~~~~~~

Homing selects what cloud selection strategy will be used. HomingGroup
is used to determine where VNF's within a given group are placed with
respect to a service component. Homing strategy is as follows:
Colocation - members of the group share the same cloud region (VIM
Domain) isolation - members of the group do not share the same cloud
region.

**Parent class:** VnfdElementGroup

       Diversity
	   - Resources are geo-diverse (cannot be co-located).

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.

Vdu
~~~

The Virtualisation Deployment Unit (VDU) is a construct supporting the
description of the deployment and operational behavior of a VNFC. A VNFC
instance created based on the VDU maps to a single virtualisation
container (e.g. a VM). A VNFC will only be in one VNFDesc. If a vendor
wants to use the VNFC in mupliple VNFDesc (their product) they can do
so, but it will be 'repeated'. References:

This information element describes compute, memory and I/O requirements
that are to be associated with the logical node of infrastructure. The
logical node requirements are a sub-component of the VDU level
requirements. As an example for illustration purposes, a logical node
correlates to the concept of a NUMA cell in libvirt terminology.
