目前许多的学校已将MPLSVPN技术加入到了网络课程的教学内容中,在进行该技术实验时一般需要同时使用多台高档次的网络设备,因此建设能满足MPLS VPN的网络实验室需要投入相当大的成本.为了解决该技术的实验问题,提出了一种通过使用GNS3软件的分布式功能,在两台联网的PC上构建MPLS VPN的虚拟实验方案.通过实验表明,利用GNS3的分布式功能,可以完全满足学习者在PC网络实验室环境中进行MPLS VPN学习的需要,同时也节省了巨额的实验设备购置成本以及管理成本,提高了实验效率,值得在网络实验课程教学中推广使用.%The MPLS VPN technology has been put into network curriculum teaching content in many schools. Which generally need use multiple sets of high-end network equipment, therefore the network laboratory construction which can meet the need of MPLS VPN experiment requires considerable cost. In order to solve the problem of MPLS VPN technology experiment, a solution is put forward by using GNS3 distributed function, to construct its virtual experiment scheme in 2 networked PC. Experiments show that, the use GNS3 distributed function, can not only fully meet the needs of the learners for studing MPLS VPN technology in the PC network laboratory environment, but also save a lot of experimental equipment purchase cost and management cost, improve the efficiency of experiment, which is worth promoting in network experiment courses teaching.
