Abstract
When a packet to a terminal is received from a terminal, a management communication processing unit transmits by broadcasting or multicasting to a network a destination information query packet for investigating a gateway device to which the terminal is connected, receives from a gateway device a destination information response packet for notifying that the terminal is connected to the gateway device, and updates a terminal information storage table based on the destination information response packet. When the terminal information storage table is erased, the history information exchange unit transmits by broadcasting or multicasting to the network a history information query packet for requesting to re-notify of the terminal that has been notified in the destination information response packet, receives from the gateway device a history information response packet for re-notifying of the terminal, and updates the terminal information storage table based on the history information response packet.
