Design and Implementation of VMP in Parallel Network Emulation

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.
