{network-role}
-----------------------------
.. req::
:id: R-69014
:target: VNF
:keyword: MUST
:validation_mode: static
:updated: casablanca
When a VNF's port connects to an internal network or external network,
a network role, referred to
as the ``{network-role}`` **MUST** be assigned to the network for
use in the VNF's Heat Orchestration Template. The ``{network-role}``
is used in the VNF's Heat Orchestration Template resource IDs
and resource property parameter names.
.. req::
:id: R-05201
:target: VNF
:keyword: MUST
:validation_mode: static
:updated: casablanca
When a VNF connects to two or more unique networks, each
network **MUST** be assigned a unique ``{network-role}``
in the context of the VNF for use in the VNF's Heat Orchestration
Template.
.. req::
:id: R-21330
:target: VNF
:keyword: MUST
:validation_mode: static

A VNF's Heat Orchestration Template's Resource property parameter that is
associated with external network **MUST** include the ``{network-role}``
as part of the parameter name.
.. req::
:id: R-11168

A VNF's Heat Orchestration Template's Resource ID that is associated with
an external network **MUST** include the ``{network-role}`` as part
of the resource ID.
.. req::
:id: R-84322
:target: VNF

A VNF's Heat Orchestration Template's Resource property parameter that
is associated with an internal network **MUST** include
``int_{network-role}`` as part of the parameter name,
where ``int_`` is a hard coded string.
.. req::
:id: R-96983

A VNF's Heat Orchestration Template's Resource ID that is associated
with an internal network **MUST** include ``int_{network-role}`` as part
of the Resource ID, where ``int_`` is a hard coded string.
.. req::
:id: R-26506
:target: VNF
:keyword: MUST
:validation_mode: static
:updated: casablanca
A VNF's Heat Orchestration Template's ``{network-role}`` **MUST** contain
only alphanumeric characters and/or underscores '_' and
**MUST NOT** contain any of the following strings:
``_int`` or ``int_`` or ``_int_``.
.. req::
:id: R-00977
:target: VNF
:keyword: MUST NOT
:validation_mode: static
:updated: casablanca
A VNF's Heat Orchestration Template's ``{network-role}``
**MUST NOT** be a substring of ``{vm-type}``.
For example, if a VNF has a '{vm-type}' of 'oam' and a
'{network-role}' of 'oam\_protected' would be a violation of the requirement.
.. req::
:id: R-58424
:target: VNF
:keyword: MUST

A VNF's Heat Orchestration Template's use of ``{network-role}``
in all Resource property parameter names **MUST** be the same case.
.. req::
:id: R-21511
:target: VNF
:keyword: MUST
:validation_mode: static
:updated: casablanca
A VNF's Heat Orchestration Template's use of ``{network-role}``
in all Resource IDs **MUST** be the same case.
.. req::
:id: R-86588
:target: VNF
:keyword: SHOULD
:updated: casablanca
A VNF's Heat Orchestration Template's ``{network-role}`` case in Resource
property parameter names **SHOULD** match the case of ``{network-role}``
in Resource IDs and vice versa.
Note that this document refers to ``{network-role}`` which in reality
is the ``{network-role-tag}``. The value of the
``{network-role}`` / ``{network-role-tag}``
is determined by the designer of the VNF's Heat Orchestration Template and
there is no requirement for ``{network-role}`` / ``{network-role-tag}``
uniqueness across Heat Orchestration Templates for
different VNFs.
When an external network is created by ONAP, the network is also assigned a
``{network-role}``. The ``{network-role}`` of the network is not required to
match the ``{network-role}`` of the VNF Heat Orchestration Template.
For example, the VNF Heat Orchestration Template can assign a
``{network-role}``
of ``oam`` to a network which attaches to an external network with a
``{network-role}`` of ``oam_protected`` .
When the Heat Orchestration Template is on-boarded into ONAP
* each ``{network-role}`` value in the Heat Orchestration Template
is mapped to the ``{network-role-tag}`` in the ONAP
data structure.
* each ``OS::Neutron::Port`` is associated with the external network it is
connecting to, thus creating the VNF Heat Orchestration Template
``{network-role}`` / ``{network-role-tag}``
to external network ``{network-role}`` mapping.
