From OpenFlow Switch Specification, there are flow tables and a group

These tables do the matching and actions.
Are OpenFlow messages handled in/by the switch or the controller @@?
OpenFlow is the protocol that OpenFlow controllers use to speak to
OpenFlow-enabled switches, controlling (amongst other things) the flow
tables you mentioned. So the answer to your question is both ends must
both generate and handle OpenFlow messages for the system to work.
