摘　　要：根据实时集群系统的高可用性和实时性要求,考虑集群系统的网络拓扑结构和网络传输性能对系统实时性能的影响,文章设计和构建了一个高可用性冗余实时集群系统,对系统的网络拓扑结构设计进行了阐述,估算了网络的数据传输性能,并讨论了系统并行计算的实现和冗余机组调度策略。经实际测试证明,系统具有较高的可用性和实时性,可作为周期性、高强度、多源浮点信息处理平台。According to the demand of high availability and real-time characteristics of real-time cluster system, and with regard to the effect of the network topology architecture of cluster system and the capability of network transmission on the system real-time performance, this paper gives a design and construction project of a redundant real-time cluster system with high availability, explains the design of systematic network topology architecture, estimates the data transmitting performance of network and discusses the realization of systematic parallel computing and the scheduling strategy of redundant group. The practical test proves that this system possesses the comparably high availability and real-time characteristics, and it can be used as the processing platform of periodical and high intensity multi-source floating-point information.
