-Programmable Provisioning of Provider Networks
-----------------------------------------------
-Description
-~~~~~~~~~~~
-
-In a NFV environment the VNFMs (Virtual Network Function Manager) are consumers
-of the OpenStack IaaS API. They are often deployed without administrative rights
-on top of the NFVI platform. Furthermore, in the telco domain provider networks
-are often used. However, when a provider network is created administrative
-rights are needed what in the case of a VNFM without administrative rights
-requires additional manual configuration work. It shall be possible to
-configure provider networks without administrative rights. It should be
-possible to assign the capability to create provider networks to any roles.
-
-The following figure (:numref:`api-users`) shows the possible users of an
-OpenStack API and the relation of OpenStack and ETSI NFV components. Boxes with
-solid line are the ETSI NFV components while the boxes with broken line are the
-OpenStack components.

-Derived Requirements
-~~~~~~~~~~~~~~~~~~~~~
- - Authorize the possibility of provider network creation based on policy
- - There should be a new entry in :code:`policy.json` which controls the provider network creation
- - Default policy of this new entry should be :code:`rule:admin_or_owner`.
- - This policy should be respected by the Neutron API
-
-Northbound API / Workflow
-+++++++++++++++++++++++++
- - No changes in the API
-
-Data model objects
-++++++++++++++++++
- - No changes in the data model
-
-Current implementation
-~~~~~~~~~~~~~~~~~~~~~~
-Only admin users can manage provider networks [OS-NETWORKING-GUIDE-ML2]_.
-
-Potential implementation
-~~~~~~~~~~~~~~~~~~~~~~~~
- - Policy engine shall be able to handle a new provider network creation and
- modification related policy.
- - When a provider network is created or modified neutron should check the
- authority with the policy engine instead of requesting administrative
- rights.
