Abstract: With the development of the network research, virtual network topology in the emualtion system grows in size and complexity, so it becomes more important that how to edit the virtual network topology efficiently and expediently to provide the emulation script for the emulation system fast and correctly. The paper presents the design and implementation of VMP, a tool that can be used to edit the network topology visually and generate the emulation script, and its use in the distributed parallel network emulator PARNEM

Key words: Network emulation; Topology editor; NS; Visual

摘要： 随着网络研究的发展，仿真系统内部的虚拟网络拓扑也变得更大、更复杂。因此如何方便、高效地编辑虚拟网络拓扑以快速准确地提供给仿真系统所需要的仿真脚本显得尤为重要。该文介绍了可视化网络拓扑编辑与仿真脚本生成工具VMP 的设计与实现及其在分布式并行网络仿真器PARNEM 中的应用。
