1. A network management module comprises:

  • a network interface module operable for providing data packet communication with a vehicle communication network;

    a memory operable to store a processing requirement database that includes mission critical processing requirement information and infotainment processing requirement information; and

    a processing module operably coupled to the network interface module, wherein the processing module executes a set of instructions stored in the memory to manage a vehicle communication network by;

    determining content type of a first packet as corresponding to infotainment content;

    determining a processing requirement of the first packet based on the infotainment processing requirement information;

    determining content type of a second packet as corresponding to mission critical operation content;

    determining a processing requirement of the second packet based on the mission critical processing requirement information, wherein determining the processing requirement of the second packet includes determining whether mission critical output will be generated in response to mission critical input;

    prioritizing execution of the processing requirement of the second packet above the processing requirement of the first packet;

    when the mission critical output will be generated, pre-queuing the mission critical output;

    wherein the second packet is processed in accordance with the mission critical processing requirement information and queued for transmission transmitted via the vehicle communication network with a higher priority relative to a lower priority of the first packet, and wherein the vehicle communication network transmits the second packet with the higher priority before the first packet with the lower priority.
