Abstract: A system for transferring a frame within an Ethernet network of a vehicle. The system includes an Ethernet switch, first and second feature modules and a NAM. The Ethernet switch includes first and second ports connected respectively to the first and second feature modules. The NAM: receives a priority request message from the second feature module; generates a priority response message indicating information for the second feature module to set a priority level of a frame; and transmits the priority response message to the second feature module. The Ethernet switch: receives the frame from the second feature module at the first port, where the frame has a first bit indicative of the priority level and a second bit indicative of a port of the first feature module; and forwards the frame, based on the first and second bits, to a corresponding one of the queues having the priority level and for transmission to the port of the first feature module.

Abstract: A mobile vehicle communication system and a method carried out by the system to determine at a remotely-located vehicle a performance criteria of a communication network connection in the vehicle. Steps of the method include: monitoring the vehicle's communication network connection for at least one of a plurality of parameters, wherein the plurality of parameters are associated with the performance criteria of the network connection; correlating a performance status test indicative of the performance criteria of the network connection with at least one of the plurality of parameters; and determining the performance criteria of the network connection based on the correlation.
