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 One Convergence NVSD Controller
|
|
=============================================================
|
|
|
|
https://blueprints.launchpad.net/group-based-policy/+spec/gbp-oc-nvsd-driver
|
|
|
|
This blueprint proposes a Group Based Policy (GBP) plugin driver to realize
|
|
GBP policy with One Convergence NVSD controller.
|
|
|
|
Problem description
|
|
===================
|
|
|
|
One Convergence NVSD controller implements an overlay fabric to provide
|
|
virtual networks and enable the deployment of network services in the
|
|
virtual networks. GBP plugin framework provides the capability to use
|
|
different drivers to render the policy definition using a specific technology.
|
|
One Convergence GBP driver is required to implement the GBP APIs [1] using the
|
|
connectivity, policy flow and service insertion primitives provided by NVSD
|
|
controller.
|
|
|
|
Proposed change
|
|
===============
|
|
|
|
We propose the addition of a new GBP driver to implement the GBP APIs [1] and
|
|
render the policy using the NVSD controller. This driver will proxy the APIs
|
|
via REST interface to the NVSD controller. The GBP driver for NVSD controller
|
|
will implement the PolicyDriver interface as defined in the abstract base class
|
|
services.grouppolicy.group_policy_driver_api.PolicyDriver.

Data model impact
|
|
-----------------
|
|
|
|
None (existing GBP model is used)
|
|
|
|
REST API impact
|
|
---------------
|
|
|
|
None
|
|
|
|
Security impact

|
|
None

|
--------------------
|
|
|
|
None
|
|
|
|
Other end user impact
|
|
---------------------
|
|
|
|
The driver will reuse the configuration for NVSD Neutron plugin [2] to access
|
|
the NVSD controller.
|
|
|
|
Performance impact
|
|
------------------
|
|
|
|
This driver should allow for a more scalable solution of GBP deployments
|
|
using the NVSD controller.
|
|
|
|
Other deployer impact

Work items
|
|
----------
|
|
|
|
1. Developing the NVSD GBP driver
|
|
|
|
Dependencies
|
|
============
|
|
|
|
Group Based Policy Plugin
|
|
|
|
Testing
|
|
=======
|
|
|
|
Unit tests will be provided.
|
|
|
|
The 3rd party One Convergence CI setup will be enhanced to cover the
|
|
testing of NVSD GBP driver using the NVSD controller.
|
|
|
|
Documentation impact
|
|
====================
|
|
|
|
Documentation needs to be updated to reflect the addition of a new
|
|
GBP driver and it's configuration parameters.
