基于CORBA的信息总线体系结构的研究与实现

CORBA在分布式环境的应用中SOAP/XML-RPC的效率低下，几乎不可能在广域网中承担重任。在网络无所不在、网络计算成为大势所趋的时代，寻求一种易用、强固、高效、跨平台和多语言支持的架构重要性不言而喻。文中介绍了一种基于CORBA的系统架构——总线型系统架构的实现模型。该模型从计算机网络化的角度出发研究，针对CORBA在分布式环境下远程调用时并发吞吐量方面的性能缺陷，提出了信息总线的具体解决方案和应用框架，并对它的性能进行分析。试验证明在同样的条件下，采用该架构大大节省了远程调用时间，提高了效率。

Research and Implementation of Information Bus Architecture Based on CORBA

The efficiency is low-lying in distributed conditions based on CORBA, it is impossible to have a comprehensive use in Internet. It is self-evident to research an architecture which are oversimplified, high efficiency and so on, since Internet is immanent and net calculate is becoming a trend. A Information Bus Architecture and its model are introduced based on CORBA architecture in this paper. The model is researched from net's view, aimed at its limitation of performance for RPC, especially for RPC whit parallel throughput in distributed environment based on CORBA.A solution and application platform are put forword, then analysed performance of the architecture. At the same conditions, test shows that a large of time for RPC is saved on and efficiency is improved highly since this architecture is adopted.
