Brocade LBaaS Plugin Driver (v2 Data Model Support)¶
URL of the launchpad blueprint: https://blueprints.launchpad.net/neutron/+spec/neutron-brocade-lbaas-driver
Brocade LBaaS Plugin and Driver for the Brocade ADX Load Balancer Devices for the LBaaS in Neutron.
The driver will implement the interfaces according to the driver interfaces mentioned in the spec https://review.openstack.org/100690 for the blueprint https://blueprints.launchpad.net/neutron/+spec/lbaas-objmodel-driver-changes
The following managers will be implemented:
Implementation is composed of Plugin Driver and Brocade Device Driver.
Brocade LBaaS Plugin Driver extends/implements the driver interfaces as mentioned above and forwards the request to the device driver.
The device driver communicates with the Brocade ADX Load Balancer Device (Physical and Virtual) via SOAP/XML APIs. The device driver use SUDs python module for the SOAP/XML API calls.
Protocols: HTTPS, HTTP, TCP LB Algorithms: ROUND_ROBIN, LEAST_CONNECTIONS Session persistence: SOURCE_IP Health Monitoring: TCP, HTTP, HTTPS Stats retrieval CRUD on loadbalancer, listener, pool, healthmonitor, member Additional lbaas features supported as part of framework in kilo release (TERMINATED_HTTPS, L7 etc)
Product Versions supported
ADX 12.5 and above Virtual ADX 3.0, 3.1 and above
- Brocade LBaaS Device Driver will raise one of the following exceptions
- ConfigError . Raised when a configuration exception occurs
on the load balancer device
- UnsupportedFeature . Raised when a particular feature is not yet

Data Model Impact¶
REST API Impact¶
Other End User Impact¶
Will support ipv6 at the same level as neutron lbaas.
Other Deployer Impact¶
service_provider entry in the neutron-lbaas.conf file needs to be updated to reflect Brocade as one of the service_provider for the plugin to be effective.
Brocade Device Driver must be installed prior to using this driver
Brocade plugin driver code
Existing LBaaS tests provide complete coverage, if driver is installed and configured (as our CI will do)
Brocade ADX CI will run existing LB tempest tests with Brocade ADX/vADX.
Brocade ADX CI will run existing LB functional tests with Brocade ADX/vADX.
Brocade ADX CI will run existing LB API tests with Brocade ADX/vADX.
