摘　　要：半实物仿真技术是大规模通信网络性能研究的重要手段,可很好地实现仿真精度和评估成本之间的均衡。现有半实物仿真平台/技术实现真实子网的接入时需要对接入设备的协议进行解析,限制了其在战术互联网半实物仿真测试中的应用。提出一种基于QualNet真实子网接入的网络半实物仿真方法,通过构建真实-虚拟网关映射表的方式将真实网络与虚拟网络进行无缝连接,解决真实网络、虚拟网络之间数据交互的路由寻址问题,实现在无需对真实设备的路由协议解析下接入真实子网。仿真实验结果表明:此半实物仿真接口消除了对接入真实子网的路由协议限制;为构建真实子网接入的网络半实物仿真系统提供了行之有效的途径,进一步完善、丰富了网络半实物仿真在战术互联网研究中的应用。Hardware-in-the-loop is a crucial method to evaluate the performance of large-scale communication networks,which achieves a good balance between accuracy and cost.The current hardware-in-the-loop emulation platforms or technologies need to parse the protocols of access devices to integrate the real subnets with the simulated network.This scheme constrains its application in the emulation of tactical network,e.g.,integrating the military radios running private protocols.Thus,a novel real-subnet-in-the-loop(RSIL)network emulation method based on QualNet is proposed to solve the problem.Specifically,the scheme is to establish a real-virtual gateway mapping table to solve the routing and addressing issues of data interaction between real and virtual networks,which can seamlessly integrate real subnets running any routing protocols with virtual simulation networks without protocol parsing.The experimental results show that RSIL eliminates the constraints on the routing protocols that the integrated real subnets run,and provides an effective way to build real-subnet-in-the-loop network emulation system,which further improves and enriches the application of hardware-in-the-loop network emulation in tactical network research.
