基于Virtools/HLA的跨广域网多联邦互联研究

Research on Interconnection of Multiple Federations in WAN Based on Virtools /HLA

针对分布仿真中跨广域网的多联邦互联问题,提出了一种基于网络游戏技术(Virtools)与高层体系结构HLA相结合的解决方法。在对当前广域网分布仿真应用模式以及游戏引擎Virtools的互联机制分析的基础上,建立了基于Virtools网络模块和HLA/RTI的分层式的多联邦体系结构:基于HLA/RTI构建仿真联邦,通过嫁接成员将这些仿真联邦衔接到Virtools的虚拟会话空间Session,在服务器的协调下,进行整个系统的监控管理以及在该Session内完成联邦数据的交互。该方法一方面继承了HLA在重用性、互操作性方面的优点;另一方面,借助于Virtools增强了仿真联邦跨广域网的交互能力,以及对多联邦的监控和管理能力。对基于该方法的多联邦体系结构、嫁接成员的设计,以及基于Virtools的多联邦的监控和管理方法进行了详细介绍。实践表明该方法能够满足大规模、大范围、复杂仿真应用的需求。

In order to solve the problem of interconnection between multiple federations, a method based on network game technology was put forward. After analyzing the application of distributed simulation based on WAN and the interconnection mechanism of game engine Virtools, a multiple level federation architecture based on Virtools Server pack and HLA/RTI was established. The detail combines the federations based on HLA/RTI with a virtual space named session in Virtools through inoculative members, and in the control of server, the surveillance and management about the whole system and the data intercommunion＇ between federations in Session were performed. In one hand, the method inherits the merit of HLA in recycle and interconnection; in the other hand, the capability of intercommunion in WAN, surveillance and management about federations were strengthened through Virtools. The architecture of multiple federations, design of inoculative members, surveillance and management about the multiple federations were illuminated based on Virtools in detail. According to the execution, the method can meet the requirement of complicated simulation which applies in huge scale and area.
