Abstract
A data collection unit of an NW controller () collects, from an L2SW () constituting an L2NW (), uplink observation data indicating traffic volume of a session request packet addressed to an application serverand downlink observation data indicating traffic volume of a session response packet transmitted from the application server, which are acquired by observing packets input to the L2SW (). A control unit changes shaping rate of the packets addressed to the application server () through the L2SW () included in the L2NW () based on a ratio between the traffic volume indicated by the uplink observation data and the traffic volume indicated by the downlink observation data, or a ratio between an increment of the traffic volume acquired from the uplink observation data and an increment of the traffic volume acquired from the downlink observation data.
