【摘要】 实时系统是一类应用极为广泛的系统,而通用CORBA规范对实时应用支持不足,所以OMG制订了实时COR-BA1.0规范.。该规范支持固定优先级的实时CORBA应用,提供了实时CORBA应用中对象调用操作端到端的可预测性。文章对实时CORBA规范中所定义的控制和管理系统资源的策略和机制进行了较为详尽的阐述,并对其进行了分析与评述。更多还原

【Abstract】 To meet the challenge of distributed object-oriented re al-time computing,a young but booming field,the Object Management Group(O MG)issues the Real-Time CORBA1.0specification which provides standard poli cies and mechanisms that support quality-of-service requirements end to end. This article analyzes the key RT-CORBA features which enhances the effectivenes s of distributed object computing middleware as a platform for performance-sens itive re-al-time systems.更多还原
