基于HLA的网络接口单元研究与实现

为了研究如何将已有的基于DIS(Distributed Interactive Simulation)标准的分布交互仿真系统移植到HLA(High Level Architecture)体系结构下以及研究基于HLA的仿真系统的开发,以分布式虚拟战场环境中的兰方分系统为研究背景,介绍了采用网络接口单元NIU(Network Inter Unit)技术将兰方分系统基于HLA标准与其它分系统的互联.介绍了兰方分系统的结构以及NIU的功能,描述了基于HLA体系结构的应用程序开发,主要是NIU的开发和实现.这种方法已经在虚拟战场环境中得到应用,效果良好. 

Implementation of Network Interface Unit Based on HLA

To study how to transit the existed simulation systems based on distributed interactive simulation (DIS) standard to high level architecture (HLA) and how to develop a new system based on HLA, taking a blue sub system of distributed virtual battlefield environment as study background, network interface unit(NIU) was adopted to guarantee the interaction between blue sub system with other sub systems, adhering to HLA standard. The configuration of the blue sub system and the function of NIU was introduced.The development of application system based on HLA were described, especially the development and implement of NIU. This method has been used in a virtual battlefield environment, it proved to be effective.
