The automobile currently has a number of processors to control different subsystems such as engine controller, transmission controller, ABS controller, lighting controller, entertainment controller, and airbag controller. These subsystems are connected as a single vehicle network. Different vehicle networks can run under different protocols such as CAN, VAN, SCP, DLC, ACP, and J1939. Controller Area Network (CAN) has become the standard for the automotive industry. However, CAN has limited speed to incorporate new applications, such as invehicle multimedia, entertainment, navigation, and computing. A new technology, Media Oriented Systems Transport (MOST), provides high bandwidth to accommodate such applications.
