Abstract
The previous chapters discuss different analysis techniques for computing the (worst-case and average-case) response time of CAN messages. These methods are based on a number of assumptions, including the availability of a perfect priority-based queue at each node for the outgoing messages, the availability of a transmit object, TxObject, for each message, the preemptability of the transmit objects, and the ability to immediately (i.e., in zero time) copy the highest priority message from the queue to the TxObjects at the source node as soon as they are available. When these assumptions do not hold, as in many cases of industrial relevance, the response time of messages can be significantly larger than what is predicted.
