FIELD: physics, computer engineering.

SUBSTANCE: invention relates to network systems. A network system comprises: a switch configured to transfer a packet based on an entry registered in a flow table; and a controller configured to set, for the said switch, a drop entry defining a match condition to specify the packet and an action to drop the packet when, as a result of packet sampling for the said switch, it is determined that the sampled packet is a cause of a traffic storm, wherein the said switch drops the packet which is the cause in a flow unit based on the drop entry when the traffic storm has occurred.
