摘　　要：针对一种建立在高可靠、高性能结点和双冗余通信网络上的实时容错分布式系统 ,将运行在实时应用程序和系统硬件平台之间的分布式实时支撑平台作为研究系统实时性的重点 ,从其实现的难点出发 ,分析了分布式实时支撑平台的技术路线、可预测性机制和具体实现方案 。This paper is based upon a kind of Fault-tolerant Real-time Distributed Computer System (FT-RTDCS)architecture which is built on high-powered and reliable node computers and dual redundancy networks.Emphasis is put on the study of Real-time Distributed Supporting Platform(FT-DSP),which works between the real-time applications and hardware platform of FT-RTDCS.To overcome difficulties of implementation,the predictable mechanism is analyzed and an implementation scheme of FT-DSP is given to support hard real-time tasks,soft real-time tasks and non real-time tasks in FT-RTDCS.
