摘要

我们研究了局部分布式实时系统中的事件处理。目标是将事件触发的通信与时间同步协议一起使用。通过以太网的IEEE 1588，以实现与静态调度时间触发系统相似的确定性水平。给定一个具有组件属性和输入事件率表征的分布式应用程序，我们讨论了一个约束性能参数的分析过程。这些参数对于应用程序的确定性实现也是必需的。该方法已在标准软件和网络组件的设置上进行了实验评估。

On Determinism in Event-Triggered Distributed Systems with Time Synchronization

We study event processing in locally distributed realtime systems. The objective is to use event-triggered communication together with a time-synchronization protocol, in particular. IEEE 1588 over Ethernet, to achieve the similar level of determinism as in statically scheduled time-triggered systems. Given a distributed application with component properties and input event rate characterization, we discuss an analytic procedure that bounds performance parameters. These parameters are also necessary for deterministic implementation of the application. The procedure is experimentally evaluated on a setup with standard software and networking components.
