摘要
在计算机网络类课程实验教学中往往会遇到设备缺乏、维护困难和实验资源利用效率低下的问题。为了解决这些问题，本文提出了一种基于虚拟化技术的网络类课程云实验平台，对实验资源进行虚拟化和整合，进而将这种统一部署和管理的实验教学环境作为一种网络服务提供给所有的教学对象使用。对教学对比实验和认同度调查数据的分析表明平台对于提升网络课程教学效果确实起到了一定的促进作用。
The Computer Network Experiment Teaching in vocational education is otten contront with 3 main problems,including：lack of experiment equipment,difficulty in laboratory maintenance and the inefficient use of experiment resources. To tackle these problems,we presented a Cloud network ex- periment Laboratory （C-Lab）based on virtualization technology. The C-Lab can virtualize and integrate the experiment infrastructure and hence provide the experiment teaching environment with unified de- ployment and management as an online service to all the teaching objects. A teaching contrast experi- ment and a student identity survey were design to investigate the effect of C-Lab. The results show that the C-Lab can exert positive effects on network experiment teaching in some extend.
