*Many ways to start two Ryu controller in one computer:*
*1. Start two ryu controller with different OpenFlow port*
*2. Use different network namespace*
*3. Run docker on lxc/docker/vz..... and seprate to different port or IP*

*I think there is no general approach to do messaging between Ryu
controllers. You might need to use message system or APIs to do that.*
