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 Nuage Networks

|
|
Group based policy driver for Nuage Networks
|
|
|
|
Problem description
|
|
===================
|
|
|
|
Nuage's Virtualized Services Platform(VSP) [1] supports
|
|
policy based orchestration which fits well with
|
|
newly defined group based policy framework in openstack.
|
|
It will enrich the VSP solution by extending its usage through openstack.
|
|
And also allow openstack user to take advantage of Nuage's
|
|
fully baked policy driven, application centric service architecture.
|
|
|
|
Proposed change
|
|
===============
|
|
|
|
We propose the addition of a new GBP driver to support Nuage.
|
|
It will implement the PolicyDriver interface as defined in the
|
|
abstract base class services.group_policy_driver_api.PolicyDriver:
|
|
|
|
We will support CRUD operation on policy-target, policy-target-group,
|
|
policy-classifier, policy-action and policy-rule resources.
|
|
|
|
The proposed GBP driver will interface with the Nuage's VSD using ReST
|
|
channel similar to how its done in Nuage's monolithic plugin. Library will
|
|
be re-used to avoid code duplication.

Performance impact
|
|
------------------
|
|
|
|
This driver should allow for more efficient and scalable solution
|
|
for group based policy control of deployments using Nuage's VSP.

|
Implementation
|
|
==============
|
|
Nuage's VSD has an inbuilt application centric APIs which will fit nicely with
|
|
GBP. The driver will act as a proxy for managing coresponding objects on VSD.
|
|
Nuagenetlib (private python library) will be used to make this call. This is inline
|
|
with implementation model for nuage's core plugin and ml2 driver. The supported
|
|
list of resources are mentioned in "Proposed change" section.

Work items
|
|
----------
|
|
|
|
1. Developing the Nuage GBP driver
|
|
2. Writing corresponding Unit and functional tests
|
|
|
|
Dependencies
|
|
============
|
|
|
|
Group Based Policy Plugin
|
|
|
|
Testing
|
|
=======
|
|
|
|
Unit tests will be provided.
|
|
Nuage CI may need to be enhanced to support this feature.
|
|
|
|
Documentation impact
|
|
====================
|
|
|
|
Documentation needs to be updated to reflect the addition of a new
|
|
GBP driver and its configuration parameters.
