+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 verison 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.
