Abstract
A gateway suppresses data volume considering processing load information of a destination to reduce communication traffic volume of a network without suppressing the information with high severity. In a network system comprising the data center, the management node and the gateway connected via a plurality of networks, a communication function section of the gateway includes a table control unit that receives the processing load information of the data center as a packet destination from the management node and retains the information in a transfer management table. A transfer stop control unit of the gateway judges whether or not transfer of the packet is suppressed using the processing load information retained in the transfer management table, and suppresses the transfer of the predetermined packet upon judgment to suppress the packet transfer.
