【摘要】 合理的业务流量模型是战术通信网仿真模型的重要部分。根据战术网络业务量所表现出来的自相似特性,在基于多重ON/OFF源汇聚模型的基础上,设计了一种利用Opnet技术生成自相似流量的方法,实现了对网络节点模型中的数据源模块的精确描述,从而可快速有效的生成符合自相似特性的业务流量。应用"方差-时间图"算法,设定不同的参数条件对所产生的流量序列进行H参数估计,实验结果表明该种流量序列符合自相似性要求且精确度高,可直接应用于战术通信网仿真和性能分析。

【Abstract】 Reasonable traffic model is an important part of tactical communication networks simulation and analysis.An implementation of creating self-similar traffic flow was put forward by using OPNET technology based on the model of assembling of multiple ON/OFF sources.It could achieve self-similar traffic flow quickly and effectively through some ameliorations of network node level model.Variance-time algorithm was adopted as authentication method.Hurst parameters estimating experiment is operation in different parameters conditions and the results demonstrate that the proposed algorithm of generating self-similar traffic sequence is authenticated and correctness.This method can be applied in tactical communication network performance analysis and network simulation.
