摘要
OPNET软件基于统计量进行仿真结果分析。传统的方法是,通过OPNET软件提供的工具在仿真结束后对统计量进行分析。但是,当OPNET软件作为大型联合仿真的一个部分且其他部分需要OPNET仿真实时统计量时,OPNET软件自身将无法满足要求。为此,提出了两种OPNET统计量实时导出方案:基于统计线的统计量导出方案,以及基于外部模型访问的统计量导出方案。首先对方案原理进行了介绍,其次详细阐述了方案实现方法,最后对方案优缺点进行分析,并给出统计量实时导出结果。通过分析得出,基于统计线的统计量导出方法实时性好,基于外部模型访问的统计量导出方案适应性好,两种方案均满足统计量实时导出性能需求。
OPNET software is used to analyze simulation results based on statistics. The statistics are analyzed at the end of the simulation using the tools provided by the OPNET software in traditional method. However,OPNET software itself cannot meet the requirements when it is part of a large cosimulation and other parts require real-time statistics of the OPNET simulation. For this reason,two realtime exporting schemes of OPNET statistics are proposed: one is based on statistic wire,and the other one is based on external model access. Firstly,the principle of the schemes is introduced. Then,the realization method of the schemes is expounded in details. Finally,the advantages and disadvantages of the schemes are analyzed,and the output of the statistics are given out. The analysis shows that the exporting scheme of statistics based on statistic wire has better real-time performance,however,external model access method has better adaptability. The two schemes satisfy the real-time performance requirements.
