| Abstract: | The paper introduces a mechanism to implement distributed scheduling for the 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 the CAN-bus, and supporting dynamic hard real-time computing by allowing dynamic reservation of communication resources. |
