Abstract
A network system of the present invention includes a switch and a controller. The controller sets a flow entry, in which are defined a rule and an action used to uniformly control a packet as a flow, in a flow table of the switch. The switch determines whether or not to perform a sampling processing to a received packet, in accordance with the flow table setting, and notifies the controller of a sampling result in a case where a sampling processing is performed to the received packet. The controller updates the flow table in accordance with the sampling result and narrows packets to perform a sampling processing.
