    • 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.
    • 本发明的网络系统包括开关和控制器。 控制器设置一个流条目,其中定义了一个规则和动作,用于在交换机的流表中统一控制数据包的流量。 交换机根据流表设置确定是否对接收到的分组执行采样处理,并且在对所接收的分组进行采样处理的情况下通知控制器采样结果。 控制器根据采样结果更新流表,缩小数据包进行采样处理。
