摘要
体现作战通信行为特点的业务流量生成是战场网络建模仿真的难点。针对现有网络流量建模与战场通信存在脱节的问题,分析了基于可变报文格式标准的典型作战任务和业务报文,提出一种面向战场通信业务的网络流量建模和仿真方法。利用两层模型分别建模战场通信业务交互和网络流量传输,上层的作战仿真模型利用计算机生成兵力技术模拟战场各单位间协同作战和通信行为,产生作战任务对应的业务报文。底层的网络流量模型利用重尾分布函数仿真报文到达时间间隔分布并模拟流量在网络中的传输过程。仿真实验结果表明模型产生的报文流量符合一般网络流量的基本特征,并能够反映战场中通信交互行为和业务对流量特征的影响。
Modeling for network traffic in communication behavior simulation is the difficulty for the research about tactical communication network. Based on the investigation of variable message format protocol, a novel method for combat-oriented network traffic modeling and simulation was proposed to solve the problem that common traffic models don’t correspond to tactical communication. Two models were used to simulate network traffic transmission and communication in combat. The combat model simulated the forces’ collaboration and communication behavior based on computer generated forces, and generated tactical communication messages. The network traffic model changed messages’ time stamp with heavy-tailed distribution function and simulates transmission of traffic in network. The experimental results have verified that the traffic from the model has the properties of general network traffic, and illustrates the influence of communication behavior on traffic’s properties.
