Road vehicles — FlexRay communications system — Part 2: Data link layer specification

ISO 17458-2:2013 specifies the FlexRay communication protocol which 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 transfer, single or multi-master clock synchronization time synchronization across multiple networks, error detection and signalling, and scalable fault tolerance.
