基于VMware、GNS3实现虚拟网络实验室

A Virtual Network Laboratory Based on VMware and GNS3

VMware、GNS3可以分别虚拟计算机与网络设备,它们能各自单独构建子网,完成网络实验。在分析了它们相互连接的原理后,提出一种在单机上实现虚拟网络实验室的方案,该方案通过和宿主机中的虚拟网卡桥接,间接实现GNS3和VMware之间的通信,并构建了1个典型的网络拓扑结构。在该虚拟网络环境下测试了Zebra路由软件包,实现了Linux主机和GNS3虚拟路由器之间的动态路由,验证了利用VMware、GNS3构建虚拟网络实验室的可行性。

The VMware and GNS3 can simulate virtual computers and virtual network equipments.After analyzing the principles of connection between the two,a method to realize co-simulations in a single computer has been proposed.By bridging to virtual network adapters in the host computer,the communication between VMware and GNS3 can be realized indirectly.Besides,a typical network topology has been constructed,in which the Zebra routing package has been tested,and dynamic routing has been implemented.The feasibility of the virtual network laboratory built by VMware and GNS3 has been verified.
