摘　　要：分析、量化半实物网络仿真中通信包转换及其对通信性能的影响程度.设计基于OPNET的半实物网络仿真模型,分析模型中真实网络节点和虚拟网络节点的映射实现原理.通过ICMP协议包实验研究虚拟与真实网络之间数据包的转换过程及其网络仿真性能.结果表明,这种网络仿真模型可将真实网络和虚拟仿真网络模型有效结合,并具有较好的仿真性能.System-in-the-loop is the way to adding the hardware devices in the loop of simulation, which improves the accuracy of the simulation results. The effect of packet transforming in SITL network simulation was quantitative analyzed. A universal SITL model of communication networks was provided based on OPNET, the implementation of the mapping were studied and analyzed between the real and virtual network nodes. The SITL model combines the real network with OPNET simulating network. The principle and performance of transform were studied based on an ICMP experiment. The throughput and delay of network simulation are showed and analyzed.
