基于HLA的OPNET仿真联邦成员设计与实现

Research and Implementation on OPNET Simulation Federate Based on HLA

讨论了OPNET仿真软件对HLA接口支持的关键技术和实现方法,结合全球信息栅格(Global Information Grid,GIG)演示系统中网络传输栅格的仿真开发背景,以HLA为仿真框架,利用OPNET网络仿真软件,设计并实现了GIG环境下网络传输栅格的性能仿真,将OPNET作为邦员加入到联邦中,与其他邦员进行交互。仿真说明了不同仿真场景下GIG传输栅格的网络性能差异,体现了GIG系统中指控栅格、计算栅格等在传输栅格支撑下相互之间实现互连互通互操作的特点。

The HLA module in OPNET allows you to include a Modeler simulation as one of federates in an HLA federation, and thus to both affect, and be affected by, events in other federates. Firstly, the key techniques and implementation of HLA interface in OPNET simulations were discussed. Then a network transmission performance simulation in GIG architecture was designed, and this simulation＇s interaction with other federates was implemented based on HLA. The network performance was affected by the interactions received, which represented different network jamming intensity. This simulation fully shows the interconnection, intercommunication and interoperability in GIG system.
