1. A vehicle network node module comprising:
a plurality of vehicle devices comprising one or more sensors, actuators, or electronic control units (ECUs), each of the plurality of vehicle devices configured to perform a respective vehicle function;
a network port configured to support communications between the plurality of vehicle devices and a vehicular communication network in accordance with a communication protocol of the vehicular communication network;
a network buffer, coupled to the network port, including at least one queue for temporarily storing packets relating to the respective vehicle functions;
a switching circuit coupled to the network buffer and the plurality of vehicle devices, the switching circuit configured to facilitate communication of packets between the plurality of vehicle devices and the vehicular communication network via the network port; and
processing circuitry coupled to the switching circuit and the network buffer, the processing circuitry configured to arbitrate access to the vehicular communication network among the plurality of vehicle devices, based on a timestamp of a packet in a lower priority queue, by determining whether to select a second packet from a higher priority queue or the packet from the lower priority queue.
