摘　　要：随着实时CORBA规范的推出,在实时领域内CORBA的应用需求日益增加。本文阐述了将CORBA应用于实时系统中优先级翻转发生的根源,并参考著名的实时CORBA实现——TAO——阐述了相应的解决方案,主要有非共享的资源分配方式、请求的动态分发和散列等。Following the publication of Real-Time CORBA specification, the needs of CORBA have become more and more in real-time field. This paper identifies the sources of unbounded priority inversions, and presents corresponding design techniques for ensuring real-time QoS in middleware on the basis of TAO that is a famous real-time CORBA implementation of Washington University. The main technology includes unshared resource allocation, active demultiplexing and perfect hashing.
