  • Patent number: 12609903
    Abstract: A system comprising: a first and second network switch each comprising a plurality of ports for coupling to one or more devices; wherein the first and second network switches are communicably coupled; wherein the first network switch, based on receipt of a network frame at its ports, is configured to: process the network frame based on its content and a first rule set to determine network frame forwarding information for the network frame; add metadata to the network frame based on the result of said processing; forward the network frame with the added metadata to the second network switch; wherein the second network switch, based on receipt of the network frame, is configured to: read the metadata and process the network frame based on the network frame forwarding information as determined by the first network switch.

  • Patent number: 11470020
    Abstract: Embodiments of a method and device are disclosed. In an embodiment, an in-vehicle network interface device includes a data port to send and receive data packets, a plurality of packet processing pipelines coupled to the data port, each to inspect a single data packet to determine an action to perform on the single data packet, and a safety module to receive the determined action from each packet processing pipeline and to select one of the determined actions to perform on the single data packet and to cause a selected one of the packet processing pipelines to perform the selected action.

  • Publication number: 20220231958
    Abstract: A network device for processing a plurality of redundant data streams, the network device configured to: receive a frame from one of the plurality of redundant data streams; compare a sequence number of the frame to a stored sequence number; and if the sequence number of the frame is greater than the stored sequence number: forward the frame to an output terminal of the network device; and update the stored sequence number based on the sequence number of the frame.

  • Patent number: 10848331
    Abstract: Aspects are directed toward a data-communication approach using an arrangement of node-node communication according to a protocol involving layered routing of payload as might be similar to layered-based communication-protocol standards used in automotive applications. A particular payload is conveyed between nodes via a protocol having a data link layer and a network layer, the latter being used to indicate to which node(s) the payload is to be routed. For compatibility with standard(s), the protocol accommodates transfer of data between nodes by permitting for use of both the data link and network layers. In some implementations, to increase efficiency and processing overhead for payload transmissions, the protocol does not require use of the network layer to indicate where to transfer the payload.
