Abstract
A network element, for use in an automotive network in a vehicle, includes one or more ports, packet processing circuitry and a validation data collector. The one or more ports are configured for communicating over the automotive network in the vehicle. The packet processing circuitry is configured to receive packets from the automotive network via the one or more ports, the packets including time-protocol packets, to process the received packets, and to forward the processed packets to the automotive network via the one or more ports. The validation data collector is configured to derive, from at least some of the time-protocol packets that are processed by the packet-processing circuitry, validation data indicative of compliance of the network element with a vehicle-safety requirement, and to make the validation data accessible from outside the network element.
