【摘要】 <正> 1 引言全球性的竞争使得从头开发和维护复杂的中间件显得日益困难。在过去的几年中,对分布对象计算中间件,尤其是CORBA的需求迅速增长,基于CORBA的企业级应用发展迅猛。但是,由于目前的CORBA规范缺乏标准的服务员交互模型,使用现有的CORBA中间件开发企业级应用仍显得过于复杂,开发周期较长,产生的软件的可重用性和灵活性也较差。于是,OMG更多还原

【Abstract】 The CORBA component model(CCM)has been adopted recently. Since the CCM standard supports greater software reuse for servers,application programmers now have a standard way to develop general-purpose client/server applications. However,due to the complexity of the standard and relative immaturity of implementations, CCM is not yet appropriate for mission-critical applications with high-performance requirements. Thus, there is increasing demand to extend Object Request Broker (ORB) middleware to support distributed applications with high performance requirements. This paper describes the design principles and optimizations to develop a high-performance implementation of CORBA which supports CCM.更多还原
