EDF Consensus on CAN Bus Access for Dynamic Real-Time Applications

The paper introduces a mechanism to implement distributed scheduling for CAN-bus resource in order to meet the requirements of a dynamic distributed real-time system. The key issues considered here, are multicasting, distinguishing between hard real-time, soft real-time, and non real-time constraints, achieving high resource utilization for CAN-bus, and supporting dynamic hard real-time computing by allowing dynamic reservation of communication resources. 1 Introduction A real-time communication system (RTCS) constitutes the backbone for distributed control applications. RTCS substantially differ in many respects from general purpose communication systems. In general, while the goals of general purpose communication systems center around throughput, RTCS focus on predictability of communication. Predictability means that the system exhibits an anticipated behaviour in the functional and the temporal domain. In the area of industrial automation and the automotive industry, field busse..
