Abstract
A transmission rate of a control message between a switch and a switch controller can be reduced. A network system includes the switch which transfers a packet based on a switch flow table, the switch controller and a front-end unit which relays the control message between the switch controller and the switch. The front-end unit includes a buffer, a flow table storage section and a buffer control section which buffers the control message which hits a buffer flow entry of the flow table in the buffer.
