Abstract: A network hub is provided for an onboard network system. The onboard network system includes first and second networks for transmission of first-type and second-type frames following first and second communication protocols. The network hub includes a receiver that receives a first-type frame. A processor determines whether or not the first-type frame received by the receiver includes first information that is a base for a second-type frame to be transmitted to the second network, to obtain a determination result, and selects a port to send a frame based on the first-type frame based on the determination result. A transmitter sends the frame based on the first-type frame to a wired transmission path connected to the port selected by the processor based on the first-type frame received by the receiver.

Abstract: An information management method collects log information of one or more home electrical apparatuses corresponding to service providers. Display screen data is generated which indicates a status of the log information. The display screen data includes groups of information which each contain information on an apparatus, a service provider corresponding to the apparatus, and log information output from the apparatus. Provision of the log information of each group is individually selectable. The display screen data is provided via a network to a display terminal that performs access to a server device. Information is received from the display terminal, which indicates that selection on whether or not provision of the log information is performed. Provision of the log information is not performed on the selected group when a determination is made that refusal of provision of the log information on the selected group is performed.

Abstract: A network system includes a first network through which a frame of a first type is transmitted in accordance with a first communication protocol and includes a second network in which a frame of a second type is transmitted in accordance with a second communication protocol. A gateway device is connected to the first network and the second network. The gateway device sequentially receives frames of the first type from the first network and determines whether to transmit data regarding the received frames of the first type to the second network. The gateway device transmits, to the second network, a frame of the second type including data regarding a plurality of the frames of the first type determined to be transmitted to the second network.

Abstract: A gateway device is connected to a plurality of electronic controllers on-board a vehicle. The gateway device acquires firmware update information, which includes at least a part of updated firmware to be applied to a first electronic controller, patch data, and information indicating where to apply the patch data. When the gateway device determines that the first electronic controller does not include a firmware cache for performing a pre-update firmware cache operation, the gateway device executes a proxy process. In this regard, the gateway device requests the first electronic controller to transmit boot ROM data to the gateway device, merges the patch data and existing firmware to create updated boot ROM data with updated firmware, and transmits the updated boot ROM data to the first electronic controller that updates the boot ROM data and resets the first electronic controller with the updated firmware.
