实时中间件体系结构的研究

提出了一个在分布式系统中建立实时中间件的实现方案,采用CORBA技术为实时应用提供3种不同的实时质量服务,即普通实时质量服务、实时质量服务和强实时质量服务,以减少等待时间、提高可预测性、更细腻的优先级调度、更合理的限时处理等来满足实时系统的要求,从而达到系统资源更加合理地分配和使用.

Study on Real-time Middleware System Architecture

With quantities of software increasing in distributed system, new software architecture must be adopted to reduce the complexity of applied software, the new architecture can also enhance the maintenance and reuse of software. Middleware technology was a way to solve this problem. In order to meet the needs of real-time system such as low latency, predictable, deadline, etc., we put forward a proposal building real-time middleware in distributed system. Through the adoption of CORBA technology, we classified the requires of real-time system into three types, general quality of service, quality of service, hard quality of service, which met the needs of various real-time applications.
