This introductory chapter reminds some general points about all the architectures of embedded systems, and takes a very surprising turn by passing judgement on the properties of the well‐known controller area network (CAN) protocol, presenting its principal limitations and finally imagining solutions which open up new horizons for decades to come. By its design and structure, the CAN protocol encourages transmission of communication frames when events occur at a node of the network. This is what is called an ‘event‐triggered’ system. In very many applications, it is or becomes necessary to trigger certain actions spontaneously at precise instants. Such systems are called ‘time‐triggered’ or systems functioning in so‐called ‘real time’ mode.
