Abstract : With the always increasing use of electronics, best using the bandwidth is of primary importance in automotive networks. An element of solution is to schedule messages with offsets, which leads to a desynchronization of the streams of messages that is very beneficial in terms of worst-case response times because the traffic is distributed more uniformly over time. Two problems, difficult from an algorithmic point of view, are to be solved: choosing the offsets and computing the worst-case response times. The talk will discuss solutions in the case of Controller Area Network, which is by far the most widely used automotive networks. Experiments demonstrate that offsets actually provide a major performance boost in terms of worst-case response time and may lengthen the lifespan of CAN, despite the availability of FlexRay.
