摘　　要：实时CORBA系统是一类重要的服务应用 .实时CORBA技术不仅具有通用实时系统的特征 ,而且是基于网络通信的分布计算 ,有着区别于其他实时系统的特征 .本文针对OMG组织制订的实时CORBA规范、固定优先级驱动的RM和DM调度算法、动态优先级驱动的EDF和LST调度算法、混合优先级驱动的MUF调度算法、多处理器和分布系统中的优先级驱动调度方法MPCP、资源访问与控制协议PCP和CPP、端到端实时CORBA系统调度模型、实时CORBA应用系统TAO系统和NraD/URICORBA系统以及相关支撑技术 ,包括实时操作系统和实时通信技术等方面 ,对实时CORBA技术进行分类、比较。Real-time CORBA systems are important applications. They not only have the characteristics of real-time systems, but also are distributed systems based on network communication, which contribute to their special features. This paper first introduces real-time CORBA specification released by OMG. Then it categories and compares some scheduling algorithms, including RM, DM, EDF, LST, MUF and MPCP. Resource access and control protocols PCP and CPP are concerned, too. It further surveys end-to-end real-time CORBA scheduling model, real-time CORBA application systems TAO and NarD/URI CORBA. It also pays attention to related supporting techniques, covering real-time operating systems and real-time communication. At last, it addresses some open problems in real-time CORBA technique.
