面向服务的高层体系结构研究

摘要

To solve the deficiency of traditional High Level Architecture ( HLA) in solving large scale simulation and improve the interoperability under WAN, the Service Oriented Architecture ( SOA) was combined to HLA, the Run-Time Infrastructure( RTI) layered framework was designed. The solutions of Web Services Provider RTI Component and federates design were given, and the dynamic modeling and simulation methodology based on semantic web services were put forward. An instance was tested under laboratory conditions, and the results show that it can a-chieve the expansion of HLA to WAN and support the dynamic discovery and execution of simulation services. This research has a certain reference value for the combination of SOA and HLA.%针对传统的高层体系结构(HLA)在解决大规模仿真问题所存在的系统的局限性问题,为解决HLA的跨广域网互操作以及联邦成员的动态运行的联接,将面向服务的体系结构(SOA)的思想与HLA相结合,设计了面向服务的运行支撑框架(RTI)分层体系结构,对涉及Web服务提供组件、联邦成员设计等关键技术给出了解决方案,提出了采用语义Web服务的动态建模仿真方法.在实验室环境下通过一个仿真实例进行了测试,结果表明,能够实现HLA向广域网的扩展,并有效支撑仿真服务的动态发现与执行,对于SOA与HLA的结合研究具有一定的参考价值.
