Fault-tolerant distributed applications based on fieldbuses may take advantage from the availability of highlydependable communication systems. In this paper, we address this problem in the context of CAN, the Controller Area Network, to conclude that CAN native mechanisms alone are unable to fulfill all the attributes of fault-tolerant communication protocols. The paper discusses how existing CAN controllers can be complemented with some simple machinery and low-level protocol modules, handling the problem effectively. The result is an enhanced CAN infra-structure able to extremely reliable communication.
