Abstract: A gateway device is wirelessly connected to a mobile device and a control device that is connected to the gateway device and controls the mobile device. The mobile device reports a completion report indicating completion of a movement work according to a movement control instruction from the control device, and wherein the control device includes a work control unit that transmits the movement control instruction to the mobile device. It is determined whether or not a failure has occurred in communication between the control device and the gateway device, and it is determined whether or not the movement control instruction executed by the mobile device passes through the gateway device in which the failure determined by the failure detection unit has occurred, and stops transmission of the movement control instruction of passing through the gateway device in which the failure has occurred to the mobile device.

Abstract: A scale-out of a gateway server is realized according to a rapid increase in communication volume, without incurring system down. A high-quality communication is provided to priority users even during scaling out the gateway server. A high-quality communication is continuously provided to priority users without incurring the system down even if the scale-out/in of the gateway server is repeated. A bandwidth control apparatus transmits packets to plural virtual nodes equipped in a server device, reads the packets from any high priority queue and any low priority queue which are associated with the subject apparatus, and limits the packets to an upper limit bandwidth determined for each of the virtual nodes, and changes association of the high priority queues and the low priority queues with the virtual node bandwidth limiters according to an instruction from the control server for determining the scale-out/in of the virtual node.
