Abstract

We present a new share-driven server-based method for scheduling messages sent over the Controller Area Network (CAN). Share-driven methods are useful in many applications, since they provide both fairness and bandwidth isolation among the users of the resource. Our method is the first share-driven scheduling method proposed for CAN, and it is based on Earliest Deadline First (EDF), which allows higher utilization of the network than CAN's native fixed-priority scheduling (FPS). We use simulation to show the performance and properties of server-based scheduling for CAN. The simulation results show that the bandwidth isolation property is kept, and that with our method a good Quality-of-Service (QoS) is provided, where virtually all messages are delivered within their deadline.
