A unified Car-IT Communication-Architecture: Design guidelines and prototypical implementation

Our research in the field of communication networks for transportation systems lead to a unified car-IT architecture based on IEEE 802.3 Ethernet. In this paper, we present a prototypical implementation of a real-time gigabit Ethernet switch with the use of a freescale MPC8541e development board and an embedded Linux. We show the communication requirements for use in an automotive scenario and present real-time accurate measurements compared to an off-the-shelf hardware design.
