[ovs-discuss] way to speak with OpenFlow module

As far as I know, most controllers will include OpenFlow protocol implementation. They communicate with switches by OpenFlow message. In this way, ovs-ofctl makes no difference, it sends / receives messages via sockets (unix, tcp, etc.). Some controller might also have OVSDB southbound, which manipulates OVS bridges as ovs-vsctl.
Some applications (like Openstack, IIRC) might have an agent running on the host to call OVS utils.

Subject: [ovs-discuss] way to speak with OpenFlow module
It is easy to push OpenFlow rules to OVS by using the OVS utility such as ovs-ofctl. Thanks all OVS developers!
However, I now want to try that function with a SDN controller and I wonder that does the SDN controller (i.e., pox, nox or floodlight) will call ovs-ofctl to install OF flows or they implement their own way (which probably works in a similar way to ovs-ofctl) to complete that tasks?
Anyone please help on my dummy question.
Thanks a lot,
