VNF and PNF On-boarding and package management
----------------------------------------------
Design Definition
^^^^^^^^^^^^^^^^^^
The ONAP Design Time Framework provides the ability to design NFV
resources including VNFs, Services, and products. The VNF provider must
provide VNF packages that include a rich set of recipes, management and
functional interfaces, policies, configuration parameters, and
infrastructure requirements that can be utilized by the ONAP Design
module to onboard and catalog these resources. Initially this
information may be provided in documents, but in the near future a
method will be developed to automate as much of the transfer of data as
possible to satisfy its long term requirements.
The current VNF Package Requirement is based on a subset of the
Requirements contained in the ETSI Document: ETSI GS NFV-MAN 001 v1.1.1
and GS NFV IFA011 V0.3.0 (2015-10) - Network Functions Virtualization
(NFV), Management and Orchestration, VNF Packaging Specification.

can be packaged with/near the VNF, if needed, to simulate any functions
or systems that connect to the VNF system under test. This component is
necessary only if the existing testing environment does not have the
necessary simulators.
Licensing Requirements
^^^^^^^^^^^^^^^^^^^^^^^
ONAP operators build the VNF License using SDC during onboarding.
Refer to the ONAP User Guide for details.
The operators require certain information regarding VNF licences.
This information currently is delivered out of band.
HEAT or TOSCA VNF packages may support such information in future.
VNF licensing behavior also has some constraints.
.. req::
:id: R-85653
:target: VNF or PNF
:keyword: MUST
:updated: dublin
The VNF or PNF **MUST** provide metrics (e.g., number of sessions,
number of subscribers, number of seats, etc.) to ONAP for tracking
every license.
.. req::
:id: R-44125
:target: VNF or PNF
:keyword: MUST
:updated: dublin
The VNF or PNF provider **MUST** agree to the process that can
be met by Service Provider reporting infrastructure. The Contract
shall define the reporting process and the available reporting tools.
.. req::
:id: R-40827
:target: VNF or PNF
:keyword: MUST

The VNF or PNF provider **MUST** enumerate all of the open
source licenses their VNF or PNF(s) incorporate.
.. req::

functions and metrics.
.. req::
:id: R-13613
:target: VNF
:keyword: MUST
The VNF **MUST** provide clear measurements for licensing
purposes to allow automated scale up/down by the management system.
.. req::
:id: R-27511
:target: VNF
:keyword: MUST
The VNF provider **MUST** provide the ability to scale
up a VNF provider supplied product during growth and scale down a
VNF provider supplied product during decline without "real-time"
restrictions based upon VNF provider permissions.
.. req::
:id: R-85991
:target: VNF or PNF
:keyword: MUST
:updated: dublin
The VNF or PNF provider **MUST** provide a universal license key
per VNF or PNF to be used as needed by services (i.e., not tied to a VM
instance) as the recommended solution. The VNF or PNF provider may provide
pools of Unique VNF or PNF License Keys, where there is a unique key for
each VNF or PNF instance as an alternate solution. Licensing issues should
be resolved without interrupting in-service VNFs or PNFs.
.. req::
:id: R-47849
:target: VNF or PNF
:keyword: MUST
:updated: dublin
The VNF or PNF provider **MUST** support the metadata about
licenses (and their applicable entitlements) as defined in this
specification for VNF or PNF software, and any license keys required to authorize
use of the VNF or PNF software. This metadata will be used to facilitate
onboarding the VNF or PNF into the ONAP environment and automating processes
for putting the licenses into use and managing the full lifecycle of
the licenses. The details of this license model are described in
Tables C1 to C8 in the Appendix.
Note: License metadata support in ONAP is not currently available
and planned for 1Q 2018.
