Research on the Key Technology of Real-Time Middleware in Open System
开放系统中实时中间件关键技术研究

The Real-Time Middleware is the best way to deal with open and real-time in the same time in open system. In this paper, the characteristic of open system, the policy of real-time implement in open system and the real-time CORBA specification and development are introduced, then the key technology of real-time CORBA in open system is discussed in detail according to the model of real-time CORBA including the technology of the real-time POA, real-time ORB, thread pool, pluggable network protocol, multiplexing and demultiplexing and presentation layer optimizations etc, which provides a viable method and research for open system real-time extension.
