We has been addressing on scalability (and HA) for Icehouse (plan to release ml2 Ryu code). The new design is deploying an openflow controller per compute node (IOW, Ryu agent on every compute node is an OpenFlow controller). OpenFlow protocol is used only inside a compute node between Ryu agent and whatever hypervisor OpenFlow switch software (ovs or something). The plugin passes the information to the controllers by OpenStack's standard RPC. > 3.

Likely we'll investigate once the ml2 migration work is finished. We would greatly apprecate if you could give what we need to do in order to make Ryu work with LBAAS.
