基于 VRNET Developer 网络半实物仿真方法研究

摘要

半实物仿真是网络仿真中的一项关键技术，在网络设计和规划中具有很广阔的应用空间。为了实现虚拟网络与物理网络相互连接，利用 VRNET Developer 仿真工具进行建模，在此基础上深入研究 VRNET Developer 的 DSITL 模型和接口模型，基于 DSITL 模块搭建一个半实物仿真网络，实现仿真网络与物理网络连通。仿真结果表明，这种网络仿真模型可以将仿真网络和物理网络有效地连接起来。%Semi⁃physical simulation is a key technology in the network simulation. It has very broad application space in network design and planning. In order to achieve the interconnection between virtual network and the physical network,the VRNET Developer simulation tools is used to model. On this basis,DSITL model and interface model of VRNET Developer is intensive studied. A semi⁃physical simulation network based on DSITL modules is constructed to realize the simulation network and physical network connectivity. The simulation results show that simulated network and physical network can be effectively connected by this network simulation model.
