The FlexRay communication protocol described in this document is specified for a dependable automotive network. Some of the basic characteristics of the FlexRay protocol are synchronous and asynchronous
frame transfer, guaranteed frame latency and jitter during synchronous transfer,prioritization of frames
during asynchronous transf
er, multi-master clock synchronization1, error detection and signaling, erro，containment on the physical layer through the use of a bus guardian device, and scalable fault tolerance.
