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.

Automotive packet data switch with pipeline diversity

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.
