Addressing key concepts, properties, and algorithms, this book offers a conceptual foundation of time-triggered communication. Contributions from experts help readers understand the various time-triggered communication protocols, including their differences and commonalities. Communication protocols covered include TTP, FlexRay, TTEthernet, SAFEbus, TTCAN, and LIN. Protocols range from low-cost time-triggered fieldbus networks to ultra-reliable time-triggered networks for safety-critical applications. The text also presents information about the use of FlexRay in cars, TTP in railway and avionic systems, and TTEthernet in aerospace applications.
