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 Cisco APIC Controller
|
|
===================================================
|
|
|
|
Launchpad blueprint:
|
|
https://blueprints.launchpad.net/neutron/+spec/group-policy-apic-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 Cisco APIC controller.
|
|
|
|
Problem description
|
|
===================
|
|
|
|
Cisco APIC controller enables you to create an application centric fabric.
|
|
If you require a policy driven network control in an openstack deployment
|
|
using the ACI fabric, the reference driver for GBP can not leverage the
|
|
efficiency or scalability provided by the native fabric interfaces available
|
|
in the APIC controller.
|
|
|
|
Proposed change
|
|
===============
|
|
|
|
We propose the addition of a new GBP driver to support the APIC controller.
|
|
It will implement the PolicyDriver interface as defined in the abstract base
|
|
class services.group_policy_driver_api.PolicyDrive.
|
|
|
|
The proposed GBP driver will interface with the APIC controller and
|
|
allow efficient and scalable use of the ACI fabric for policy based control
|
|
from GBP plugin.
|
|
|
|
Alternatives
|
|
------------
|
|
|
|
There are no alternatives to use the native capability of the ACI fabric
|
|
for policy based control from openstack APIs.
|
|
|
|
Data model impact
|
|
-----------------
|
|
|
|
None (existing models for GBP should suffice to capture policy for ACI)
|
|
|
|
REST API impact
|
|
---------------
|
|
|
|
None
|
|
|
|
Security impact

|
|
|
|
None
|
|
|
|
Notifications impact
|
|
--------------------
|
|
|
|
None
|
|
|
|
Other end user impact
|
|
---------------------
|
|
|
|
The configuration files will need to be updated for using this driver.
|
|
These parameters include the addresses, credentials, and any configuration
|
|
required for accessing or using the APIC controller. Where possible, it
|
|
will share the configuration with APIC ML2 driver.
|
|
|
|
Performance impact
|
|
------------------
|
|
|
|
This driver should allow for more efficient and scalable solution
|
|
for group based policy control of deployments using an ACI fabric.
|
|
|
|
Other deployer impact
|
|
---------------------
|
|
|
|
As above, there is a configuration impact.
|
|
|
|
Developer impact
|
|
----------------
|
|
|
|
None

Work items

|
----------
|
|
|
|
1. Developing the APIC GBP driver
|
|
|
|
Dependencies
|
|
============
|
|
|
|
Group Based Policy Plugin
|
|
|
|
Testing
|
|
=======
|
|
|
|
Unit tests will be provided.
|
|
|
|
Since access to an APIC controller is required for testing the
|
|
proposed changes, 3rd party testing is required and will be
|
|
provided by Cisco CI system.
|
|
|
|
Documentation impact
|
|
====================
|
|
|
|
Documentation needs to be updated to reflect the addition of a new
|
|
GBP driver and its configuration parameters.
