A user station for a bus system and a method for broadband CAN communication are provided. The user station includes a control unit for controlling an access of the user station via a first bus system to a bus of a second bus system of the communication system, the first bus system being designed for a communication, in which at least at times an exclusive, collision-free access of one of at least two user stations of the communication system to a bus of the first bus system is ensured, and the bus of the second bus system having at least two channels, via which it is possible to transmit messages of the at least two user stations of the communication system in different separate frequency ranges temporally independently of one another.

A method for establishing a wireless data link between at least two vehicles which are connected to one another via a physical data link includes transmitting link parameters of the wireless link via the physical data link connecting the at least two vehicles and establishing the wireless link using the link parameters transmitted via the physical data link connecting the at least two vehicles.

The present invention provides an in-vehicle communication device and an in-vehicle system that can establish communication, in a short time, between applications corresponding to the same communication protocol between in-vehicle processing devices connected to communication buses having different communication protocols. In the present invention, when the first communication controller 33 has received a specific message from the first in-vehicle processing device 102 connected to the first communication bus 101, the in-vehicle communication device 1 transmits a communication protocol switching command from the second communication controller 3 to the second in-vehicle processing device 202 connected to the second communication bus 201 to switch a communication protocol setting of the second communication controller to the same communication protocol setting as that of the first communication bus.

Parallel Redundancy Protocol (PRP) using non-overlapping Resource Unit (RU) groupings may be provided. A first computing device may associate to a first Access Point (AP) at a virtual Media Access Control (MAC) address. Next, the first computing device may associate to a second AP at the virtual MAC address. Then data from a data frame may be replicated to a first one or more RUs in a channel. The first one or more RUs may be assigned to the first AP. Data from the data frame may then be replicated to a second one or more RUs in the channel. The second one or more RUs may be assigned to the second AP and may not overlap the first one or more RUs.

Technology descried here can be used for collecting information about malicious attacks on computer devices. Hosting hardware can be configured to host virtual machines, virtual machines of ECU images, and ECUs to collect records of malicious attacks. An attack analyzer can generate fingerprints from the malicious attacks.

In a relay device, a control unit stores, in a temporary storage unit data which is received by an Ethernet communication unit through a communication line. When the data stored in the temporary storage unit is transmitted, the control unit deletes the transmitted data from the temporary storage unit. When the control unit determines that, for the data received by the Ethernet communication unit, the amount of data stored in the temporary storage unit is equal to or greater than a threshold value, the Ethernet communication unit transmits instruction data giving an instruction to stop transmission through a communication line and to perform transmission through a communication bus.

An optical backplane for an optical communication network architecture distributing data to equipment. An optical demultiplexer having an input port and at least two output ports. The input port coupled to an optical fiber to carry at least two multiplexed channels of different wavelengths, a control/management channel to control/manage the network and a service dedicated channel. The output ports deliver the control/management channel and at least one service dedicated channel. A coupler receives and transmits one portion of the control/management channel to an interface box coupled to an item of equipment, and another portion of said channel to an optical multiplexer. A routing device for each output port receives a channel either to transmit said channel to the optical multiplexer in a first position or to transmit one portion of said channel to the interface box and another portion of said channel to the optical multiplexer in a second position.

A fault-tolerant command and control system including a plurality of flight devices, a plurality of flight computers, a distribution network including a plurality of switches and cables connecting the plurality of flight devices to the plurality of flight computers, and a power source connected to the distribution network.

A plurality of zones is formed in a communication network on the vehicle, and a communication path in a loop form is formed in each zone by zone trunk lines and a backup line. The backup line is connected by a switch only at the time of disconnection so that the loop is not closed. At the time of disconnection detection, an instruction is automatically given to rewrite content of routing maps on zone ECUs and a central gateway. Since each node preferentially selects a communication path that bypasses a disconnection portion from the start of communication by rewriting the content of the routing maps, it is possible to avoid an increase in communication delay. An inter-zone backup line connecting a plurality of zones is provided to enable the use of a new path across the plurality of zones at the time of disconnection.

An in-vehicle communication system includes a first relay apparatus installed in a first area of a vehicle, and a second relay apparatus installed in a second area and are connected via a communication main line. A main control apparatus and an auxiliary control apparatus are connected to the first relay apparatus and a controlled apparatus is connected to the second relay apparatus, each connected via a communication branch line. The first input apparatus is installed in the first area and inputs information to the main control apparatus and the auxiliary control apparatus. The second input apparatus is installed in the second area and inputs information to the main control apparatus and the auxiliary control apparatus via the first relay apparatus and the second relay apparatus. The first relay apparatus and the controlled apparatus communicate via an auxiliary communication line provided into both the first area and the second area.
