This patch fixes existing specs to totally conform to tox py27 environment tests as specified by tests/test_titles.py. Semantic information of all existing specs has not been changed. Specifically, this patch makes the following changes: * Fixes all titles and subtitles' capitalization inconsistencies: defaulting to only having the first word being capitalized (this seems to be the general rule in group-based-policy-specs); * Adds missing titles and subtitles to some specs; * Changes tests/test_titles.py for consistency: only 1st word capitalized; * Changes tests/tests_titles.py: subtitle count inside Testing or Documentation impact no longer restricted to 0.

Group Based Policy Driver for OpenDaylight Controller
|
|
=====================================================
|
|
|
|
Launchpad blueprint:
|
|
https://blueprints.launchpad.net/group-based-policy/+spec/gbp-odl-driver
|
|
|
|
GBP plugin has defined a multi-driver based framework to support
|
|
various implementation technologies (like ML2 has done for L2 support).
|
|
This blueprint proposes a Group Based Policy (GBP) driver to enable GBP
|
|
plugin to be used with OpenDaylight (ODL) controller.
|
|
|
|
Problem description
|
|
===================
|
|
The Group Based Policy blueprint has proposed new application centric APIs for
|
|
Neutron. Similar to the work in Neutron, there is work in the OpenDaylight
|
|
project to implement these APIs as well. With the APIs being implenented in
|
|
both of these open source projects, we propose a GBP driver to allow OpenStack GBP to orchrestrate ODL GBP
|
|
|
|
Proposed change
|
|
===============
|
|
The proposed change will:
|
|
1. Add a new ODL GBP Policy Mapping Driver to support OpenDaylight GBP. It will implement the PolicyDriver interface as defined in the abstract base class services.group_policy_driver_api.PolicyDriver, as documented in the GBP BP. The proposed GBP/ODL Mapping Driver will interface with ODL controller for GBP related operations, and with Neutron ML2 for network/subnet/port related operations.
|
|
|
|
2. Add a new ODL GBP Mechanism Driver for Neutron ML2 Plugin. Such a mechanism driver will provide a feedback loop to the ODL GBP Policy Mapping Driver to trigger policy target related operations when a VM is plugged into the Neutron port.
|
|
|
|
Alternatives
|
|
------------
|
|
There are no alternatives to leverage the native GBP API in ODL.
|
|
|
|
Data model impact
|
|
-----------------
|
|
None, as this change is simply adding support for new API extensions.
|
|
|
|
REST API impact
|
|
---------------
|
|
The ODL policy driver will have support for the new GBP API extensions
|
|
added.
|
|
|
|
Security impact
|
|
---------------
|
|
None.
|
|
|
|
Notifications impact
|
|
--------------------
|
|
None.
|
|
|
|
Other end user impact
|
|
---------------------
|
|
Users deploying OpenStack with the Group Based Policy extensions will be able to
|
|
utilze these new APIs in conjunction with the Helium version of OpenDaylight.
|
|
|
|
Performance impact
|
|
------------------
|
|
No change here.
|
|
|
|
Other deployer impact
|
|
---------------------
|
|
To utilize the GBP APIs with OpenDaylight, the following versions of software
|
|
are required:
|
|
* Neutron: Juno
|
|
* OpenDaylight: Helium
|
|
|
|
Developer impact
|
|
----------------
|
|
None.

Work items
|
|
----------
|
|
1. Add an OpenDaylight policy mapping driver to support Group Based Policy APIs
|
|
2. Add an OpenDaylight GBP Mechanism Driver for Neutron ML2 Plugin

Dependencies
|
|
============
|
|
Group Based Policy Service Plugin
|
|
|
|
Testing
|
|
=======
|
|
Additional unit tests will be added. Furthermore, ODL policy driver should be added as part of OpenStack GBP's CI system
|
|
|
|
