Hello, In the openflow flow-mod, flow rules are installed in the switches for a flow, after that subsequent packets for that flow need not to go through the controller. They are forwarded from the switch. In contrast, packet-out messages, the controller does not install any rule in the switch for a flow, therefore the subsequent packets for that flow again have to come to the controller for any forwarding purpose. Hope this answers your question :).
