摘要 实时 CORBA系统必须能够保证 CORBA调用的端到端执行时间可预测性 .分析了实时 CORBA系统中影响调用时间确定性的因素 ,介绍了 RTORBUS这一实时 CORBA原型系统的实现结构 ,阐述了设计思想和依据 ,并给出了关键数据结构 .通过与其他通用 CORBA系统的比较和性能测试 ,表明 RTORBUS系统可以有效地减少优先级倒置 ,提高 Real-time CORBA systems need to guarantee the predictability of end-to-end CORBA request execution. Pointsed out uncert ain fact ors of a request execution in real-time CORBA systems. the design of RTOR B US was introduced in detail and design principles and key data structure were di sc ussed. With performance tests and comparison with other general CORBA systems, t he paper manifested that RTORBUS effectively reduces priority inversions and gre atly improves both determinability and predictability of request execution.
