Important researches have presented different approaches in the real-time embedded communication domain aiming to cover the growing demands of performance, predictability and reliability of emerging applications. Such requirements involve low latency, reduced jitter, time composability, fault-tolerance and finally, support for future extensions. In agreement, the FTT (Flexible Time-Triggered) model is an approach which aiming to provide flexibility on the time-triggered traffic together with timeliness, differently of others protocols. This paper present some results of an enhanced FTT-CAN implementation for automotive application which was developed over an embedded Linux with RTAI extension. Additionally some design issues are provided and discussed.
