摘　　要：软件仿真是研究网络性能的重要手段,但目前不断扩大的网络规模,日趋复杂的网络架构却使仿真建模的准确性和仿真结果可靠性验证越来越困难。而半实物仿真将硬件设备嵌入软件仿真中,能提供更客观准确的仿真结果。本文提出了一种新的基于OPNET的网络半实物仿真模型HIOP(Hardware-in-loopwithOPNET),使实际节点映射到虚拟仿真网络中。模型能将实际网络和OPNET虚拟网络有效结合起来,既避免了建立复杂的实物测试平台,又提高了仿真的可信度。Simulation is an important method for the research of network performance. However,currently it become more and more difficult to verify the simulation models and the reliability of the simulation results, due to the rapidly increasing network scale and complex network structure. And HIL （Hardware-in-loop） simulation provides more exactly results. This paper presents a new network hardware-in-loop simulation model HIOP,which can map the real node into the virtual network.The HIOP model combines the real network with OPNET simulating network efficiently,which can avoid building the complex hardware experiment platform and improving the reliability of simulation.
