Abstract: A computing device, in particular for automotive applications, includes Ethernet connectivity for virtual machines on several systems on a chip. A vehicle comprises such a computing device. The computing device comprises two or more systems on a chip, each system on a chip comprising one or more virtual machines, wherein one system on a chip provides a connection to an Ethernet network, and wherein the two or more systems on a chip are connected by a switch. The virtual machines are connected via a virtual Ethernet link. For this purpose, each system on a chip comprises an instance of a distributed virtual switch, which is configured to provide a virtualized access to the Ethernet network for the virtual machines of the respective system on a chip.

Abstract: A computing device, in particular for automotive applications, with Ethernet connectivity for virtual machines on several systems on a chip are connected with point-to-point data links. The computing device includes two or more systems on a chip. One system on a chip is a root system on a chip, and the other systems on a chip are end point systems on a chip that are connected to the root system on a chip with point-to-point data links. Each system on a chip includes one or more virtual machines, and wherein one system on a chip provides a connection to an Ethernet network. The virtual machines are connected via a virtual Ethernet link. For this purpose, each system on a chip comprises an instance of a distributed virtual switch, which is configured to provide a virtualized access to the Ethernet network for the virtual machines of the respective system on a chip.

Abstract: The present invention is related to a computing device (CD), in particular for automotive applications, with a safe and secure coupling between virtual machines (VMi) and a peripheral component interconnect express device (PCIe-D). The invention is further related to a vehicle comprising such a computing device (CD). The computing device (CD) comprises one or more virtual machines (VMi) and a virtual switch (VS). The virtual switch (VS) is configured to provide a safe and secure coupling between the one or more virtual machines (VMi) and at least one peripheral component interconnect express device (PCIe-D) configured to support single-root input/output virtualization, to which the computing device (CD) is connected.

Abstract: A method for data integrity check in a network device of a computer network. The network device includes a communication module and a monitoring module. The monitoring module receives (a) the same data being received by a communication module from an input port of the network device, and (b) the same data the communication module transmits towards output port/s of the network device.

Abstract: A network device for a computer network (1), the network device (2) including communication channels (3), a PHY chip (4) configured for transmitting data in a raw data stream on the communication channels, and a MAC chip (5) configured for encapsulating data to be transmitted into frames, and for calculating a checksum for each frame. The PHY chip is configured for receiving frames of the MAC chip and transmitting transmission data contained in the frames via at least one of its communication channels. The PHY chip is configured to calculate, after receiving a frame and before sending the data of the frame in a raw data stream, a checksum of the data contained in the frame, and to this checksum with the CRC contained in the frame. The data contained in the frame are transmitted if the comparison of the checksums delivers identical values. If the comparison delivers non-identical values, then a specifiable or specified action is executed.
