摘要

可靠的实时系统是由通过复制网络通信的容错组件构建而成的。它们遵循严格的设计原则，以便在高可靠性环境下提供正确的服务。通过不同级别的复制，可以获得较高的可靠性。系统组件由两个主动冗余模块组成。本文提出了一种研究系统部件不同冗余分布的可调可靠度方法。仿真结果表明了元件冗余对系统可靠性的影响。通过对不同组件冗余分布的系统进行比较，发现在某些情况下，采用一个、两个和三个模块的节点可以获得更高的可靠性。

A Fault-Tolerant Real-Time System with Adjustable Reliability

Dependable real-time systems are built out of fault-tolerant components that communicate through a replicated network. They obey strict design principles in order to deliver a correct service in high reliability environments. High reliability is obtained applying replication at different levels. System components are built with two modules operating in active redundancy. The paper presents the approach of adjustable reliability which studies different redundancy distributions of system components. The simulation results show the influence of component redundancy on system reliability. The comparison of systems with different component redundancy distribution shows that in some cases higher reliability can be achieved using nodes with one, two, and three modules.
