中文摘要：

针对传统高层体系结构（high level architecture，HLA）在解决大规模仿真问题时存在的不足，为实现HLA向广域网的扩展，提出了面向服务的运行支撑环境（run-time infrastructure，RTI）分层体系结构。将面向服务的体系结构（service oriented architecture，SOA）与HLA相结合，将Web服务技术应用于RTI，对涉及的Web服务提供组件、联邦成员设计等关键问题给出了设计方案，并通过实例在实验室环境下进行了仿真测试。测试结果表明，该设计能有效支撑广域网环境的分布式仿真应用。

英文摘要：

To solve the deficiency of traditional high level architecture in solving large scale simulation, and achieve the expansion of the HLA to wide area network （WAN）, put forward a new method of Run-Time Infrastructure （RTI） layered framework. Combine service oriented architecture （SOA） with HLA, the Web services provider RTI component and federate was designed. An instance was tested in lab environment, results show that the method can effectively support distributed simulation applications in WAN.
