Abstract: A branding and configuring system for devices of a vehicle to be branded includes: an Ethernet switch including ports; a branding module connected to the Ethernet switch and generating new identification information for each of the devices and send the new identification information via a respective one of the ports to that device; and the devices connected respectively to the ports and including a RAM and a NVM. Each of the devices is configured to: store the corresponding new identification information received from the branding module for that device in the RAM or replace identification information stored in the RAM of that device with the corresponding new identification information in the RAM; and based on the new identification information, receive programming from a testing device external from the vehicle to reprogram that device for a dedicated functional role within the vehicle.

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.
