基于VMware的Link11数据链半实物仿真技术

The high hardware cost and limited resources may be caused by real radio access in the large-scale network hardware-in-the-loop simulation of tactical data link. For the problems above, a novel hardware-in-the-loop simulation test architecture integrating VMware with QualNet was designed. Specifically, instead of using real radios, the multiple virtual machines running digital radio model, initiated on the VMware, are integrated with the simulation network. Based on this architecture, a dynamic simulation interface for Link11 data link based on VMware and a digital radio model for Link11 radio are designed to implement the real-time data interactions between the Link11 digital radio model running on virtual machines and the Link11 virtual network model in QualNet, such as dynamic parameter acquisition, parameter reconfiguration and so on. The virtual machine running digital model, instead of real equipment, can be used to effectively reduce the required hardware cost while ensuring the accuracy of network simulation. The experimental results prove the feasibility and high efficiency of the proposed hardware-in-the-loop emulation architecture.
