摘要： 基于CORBA异步消息中的抽象Polling模型提出了一种Polling模型实现方案，讨论了其中的核心算法，该算法能分解耦合请求和应答并确保at-most-once语义。在分布对象中间件平台StarBus上实现了该模型和算法，实现结果表明该模型和算法为在CORBA中实现异步Polling机制提供了一种有效的参考方案。

Abstract: This paper presents a polling implementation schema based on the abstract polling model, introduces the kernel algorithm, which decouples request and reply and ensures at-most-once semantic. It implements the model and algorithm on the distributed object-oriented middleware StarBus. The result shows that the model and algorithm of this system provide an efficient way to implement CORBA polling mechanism.
