Influence of Internet Controller DiffServ Module on Tactical Internet Simulation

为了研究互联网控制器仿真模型的DiffServ模块对战术互联网仿真的影响,分析了区分服务模型的体系结构,构建了包含DiffServ模块的互联网控制器仿真模型。在VRNET仿真平台上构建了不同地形条件下的战术互联网仿真网络,分别统计了包含DiffServ模块与不包含DiffServ模块的仿真模型的态势时延、数据时延、话音时延以及业务成功率。仿真结果表明:包含DiffServ模块相对于不包含DiffServ模块的仿真模型的态势业务量成功率略微提升,态势时延下降,而数据业务和语音业务成功率有所下降,数据时延和语音时延略微上升。

In order to study the influence of the Differentiated Services（ DiffServ） module of the Internet controller simulation model on the tactical Internet simulation,this paper analyzed the system structure of the DiffServ module. The Internet controller simulation model with DiffServ module was constructed.Tactical Internet simulation networks under different terrain conditions were constructed on the VRNET simulation platform,respectively. The statistics of the situation time delay,data delay,voice delay and service success rate of the simulation model including the DiffServ module and not including the DiffServ module were analyzed respectively. Compared to not including DiffServ module of the simulation model,the simulation results show that business situation success rate of the simulation model contained DiffServ module has slightly improved,and its state delay decreases,and its data service and voice service success rate declines and the data delay and latency voice slightly rises.
