针对过去研究中高层体系结构( HLA)分布式仿真框架无法很好地在广域网上运行，与其他系统接口复杂，联邦成员开发语言单一，系统开发和维护成本高等特点，提出一种快速扩展HLA/RTI仿真Web服务的框架。该框架将HLA/RTI接口基于面向服务体系结构( SOA)进行封装，并在HLA/RTI中心节点部署联邦大使管理代理，通过使用HTTP协议和将代理的联邦大使和用户进行映射，实现HLA仿真系统与编程语言和平台的解耦，具有快速开发、部署、高度可定制化等特点，为中小企业和机构实现HLA仿真扩展提供了一种新思路。实验结果表明，该框架对HLA高层体系结构的扩展是可行的，不仅极大提高了HLA扩展效率，而且满足了平台多样性、联邦成员开发语言解耦、效率高等需求，还有效降低了开发和维护成本。%A Web services frame is proposed for fast extension of the High Level Architecture ( HLA) . This new frame is aimed to solve the problem of the old frame of the HLA distributed simulation that the latter can not operate smoothly on the WAN and makes the inter-faces complex with other systems and the development languages single for the federal members. The new frame could make the HLA/RTI interfaces packaged by the SOA and decouple the HLA simulation system,the programming language and the platforms through the using of the HTTP protocol and the mapping of the users and the federal members with the agency of the federal members in the HLA/RTI center node. The characteristics of the fast development and the deployment and the highly customizable also could be reflected in this frame. A new idea to achieve the HLA simulation extension has been shown through this new frame for the companies and the institu-tions. The result of the project shows that this new frame is feasible for the extension of the HLA. It could improve the efficiency of the extension of the HLA and satisfy the needs of the high portability,the high efficiency,the decoupling of the programming language of the federal members and so on. The development and maintenance cost also could be reduced in the new frame.
