ABSTRACT

In classic CAN networks, the communication has two main characteristics: The communication is event-triggered, and the shared medium is a bus. Both of these properties lead to limitations of the conventional CAN protocol in the context of dependable embedded systems. An example of a hazard to reliability is the missing fault isolation for babbling idiot failures [327]. A faulty CAN node can disrupt the communication abilities of all other nodes by continuously transmitting high-

the topology, conventional CAN does not provide time-triggered concepts like dedicated communication slots for real-time communication, because conventional CAN does not make use of a priori knowledge about communication activities.
