This change causes neutron-dynamic-routing to stop consuming Ryu in favor of os-ken. os-ken becomes the reference implementation for BGP services and neutron-dynamic-routing no longer has a dependency on Ryu.

Agent
Neutron-dynamic-routing implements a new agent named "DRAgent". The
agent talks to the neutron-dynamic-routing plugin which resides in the
neutron server to get routing entity configuration. DRAgent interacts
with the back-end driver to realize the required dynamic routing
protocol functionality. For details, please refer to the system design
document system-design
Note
One DRAgent can support multiple drivers but currently ONLY os-ken is integrated successfully.
Scheduler
Neutron-dynamic-routing scheduler, schedules a routing entity to a proper DRAgent.
BGP Scheduler
BGP Speaker and DRAgent has 1:N association which means one BGP speaker can be scheduled on multiple DRAgents.
Here is an example to associate/disassociate a BGP Speaker to/from a DRAgent.
