Hi Ben,
I understand that when an openflow controller is set on the switch, the switch will try to connect to the controller target and keeps alive the connection by a series of echo_requests and echo_replies. So, I thought, we need a passive connection that listens on the target that is configured for the controller and respond to the requests from the switch. I also thought this will help in responding to the packet-in requests as soon as it arrives. I hope my understanding is correct, if not, please correct me.

Thank you,
Babu

Doesn't it work to just start a second connection to the controller, in
the same way that ofctrl connects to the controller?
