摘要： To reduce a load of an inspection process on a server apparatus . A computer system includes a server apparatus, a gateway apparatus, and a plurality of devices coupled to the gateway apparatus. The gateway apparatus retains a range of a normal value of a device, calculated based on device information, for the plurality of devices, and when device information related to a certain device is not included in a range of a normal value of the device, notifies the server apparatus of the fact that an anomaly with respect to the device has been detected. When the server apparatus receives from the gateway apparatus a notification of the fact that an anomaly has been detected, the server apparatus inspects device information related to the device in which the anomaly had been detected.

摘要： In packet communication using TCP, a gateway device for relaying communication packets between a mobile node and a correspondent node, temporarily rewrites a parameter of the receive window size of the ACK packet of the TCP communication from the mobile node, to adjust the amount of communication packets transmitted from the correspondent node. Whit this configuration, it is possible to reduce the packet loss due to error control for the existing TCP communication with respect to the mobile node, without converting the mobile node and the correspondent node.

摘要： Constructed is a network management system which manages, in an integrated manner, a first communication system, a second communication system and a third communication system passed through by packets that are sent and received via wireless communication between a first device and a second device. The network management system performs information setting to these communication systems for dividing a communication system group, which includes these communication systems, into a plurality of logical partitions each corresponding to a plurality of different service levels based on the management information of each of these communication systems. A logical partition corresponding to a service level with regard to each of the plurality of different service levels is a partition passed through by packets that are sent and received via wireless communication between the first device and the second device belonging to that service level.

摘要： 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.

摘要： Radio communication system includes mobile terminal (UE), plurality of base stations connected by radio to the UE, gateway apparatus (GW) connected to the plurality of base stations, and data distribution server (SV) which is connected to the GW over the Internet and which distributes data to the UE. UE transmits a first data request (DR) and a second DR to the data distribution server through the base station and the GW. When the GW receives the first DR from the base station, GW transmits the received first DR to the data distribution server independent of a radio transmission load state from the base station to the UE. When the GW receives second DR from the base station, GW transmits the received second data request to the data distribution server with delay in accordance with radio transmission load state from the base station.
