摘要

考虑一个由许多计算机节点组成的分布式计算机系统,每个节点都通过控制器局域网(CAN)总线相互连接。我们证明,如果使用速率单调(RM)分配消息流的优先级,并且如果CAN总线的请求容量不超过25%,则满足所有截止日期。

The utilization bound of non-preemptive rate-monotonic scheduling in Controller Area Networks is 25%
Consider a distributed computer system comprising many computer nodes, each interconnected with a Controller Area Network (CAN) bus. We prove that if priorities to message streams are assigned using rate-monotonic (RM) and if the requested capacity of the CAN bus does not exceed 25% then all deadlines are met.
