CORBA实时性研究初探

The Pilot Study of CORBA Real_time Performance

ＣＯＲＢＡ是有关用于简化分布式应用与服务软件开发的对象请求中介的一个中间件标准。该文主要讨论了基于ＣＯＲＢＡ的对象请求中介的两个方面。首先，论述了常规ＣＯＲＢＡ实现中有关性能优化及服务质量上的缺陷；其次，阐述了实时应用对基于ＣＯＲＢＡ的对象请求中介的要求，并提供有关性能优化策略。

CORBA is an emerging middleware standard for Object Request Brokers(ORBs)that simplifies the development of distributed applications and services. This paper focus on two aspects of CORBA ORBs. First,it describes the lack of performance optimizations and quality of service(QoS)features in conventional CORBA implementations. Second, it describes the requirements of CORBA ORBs for real-time applications and provides the ways of performance optimizations.
