Research and Implementation of Real-time CORBA Platform Dependent Layer
实时CORBA平台依赖层的研究和实现

Real-time CORBA plays more and more important role in many fields such as telecom,electric business,stock and complex industry control. This article first discusses the requirement of thread library of distributed middleware and developing distributed applications.Base on real-time CORBA,this article designs and implement an object-oriented real-time Platform Dependent Layer(PDL) of Java-like thread with C ++ .PDL has fixed-priority scheduling strategy and can run on different operating systems.PDL can map CORBA priority levels to native priority. PDL can limit effectively the priority inversion and provide flexible thread management policy.
