No, every switch does not need to be directly connected to a controller. You can do one of two things:
1) run a separate management network, using the switch's native firmware (e.g., spanning tree, mac address learning) to connect to the controller 2) run in-band control, which is some approximation of static switching rules and mac address learning If you want more info on either, I would recommend doing some searches on the list archives. - Rob .
