Problem Description
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.
Proposed Change
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:
- LoadBalancerManager
- ListenerManager
- PoolManager
- MemberManager
- HealthMonitorManager
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.
