A10 Networks LBaaS Driver
==========================================

https://blueprints.launchpad.net/neutron/+spec/a10networks-lbaas-driver

Resubmitting Icehouse BP.  Neutron/LBaaS driver for A10 Networks appliances.


Problem description
===================

The new driver would allow using A10 Networks ADC appliances (hardware or
software) as backends for Neutron/LBaaS functionality.


Proposed change
===============

The driver will implement the interfaces in the lbaas abstract_driver, using
axAPI version 2.1, a JSON HTTP interface for configuring A10 appliances.  The
currently implemented methods are:

* create_vip
* update_vip
* delete_vip
* create_pool
* update_pool
* delete_pool
* stats
* create_member
* update_member
* delete_member
* update_pool_health_monitor
* create_pool_health_monitor
* delete_pool_health_monitor

Among the current LBaaS functionality (as of Icehouse), the only unsupported
feature is APP_COOKIE persistence.

Driver will support  the upcoming Juno LBaaS object model changes.  Juno TLS support will be included in a future blueprint.

Work Items
----------

* A10 driver code
* Unit tests
* Voting CI

Dependencies
============

Driver likely affected by LBaaS model and TLS changes for Juno:

* https://blueprints.launchpad.net/neutron/+spec/lbaas-api-and-objmodel-improvement

* https://blueprints.launchpad.net/neutron/+spec/lbaas-ssl-termination


Testing
=======

* Unit tests

* A10 QA

* Existing LBaaS tests provide complete coverage, if driver is installed
  and configured (as our CI will do.)

* Not testable in gate, requires hardware.  Third party CI will be in place.


Documentation Impact
====================

None.
