本文首先介绍了分布式实时系统的应用背景 ,论述了两种传统的分布式实时系统的体系结构 ,重点研究了两种新型结构特征 ,目前采用这种新结构的实时系统还不多 ,但实验证明这两种体系结构很适合分布式实时环境的应用 This paper firstly introduces the application background of distributed real-time system, discusses the architecture of the two traditional distributed real-time systems, and focuses on two new types of structure features. At present, there are not many real-time systems using this new structure. However, It is proved that these two architectures are suitable for the application of distributed real-time environment
