Research on application of virtualization in network technology course

Network technology is a course focusing on practice, which requires the students to master the configuration for different kinds of network devices and different OS network services. It would be not only money costly, if we needed to always use real devices during our teaching and learning practice, but also time costly because of the complexity of network devices/services environment, and the students is hardly to catch the learning point. The article proposed a solution based on virtualization technology for those issues, and the opportunities to the solution's optimization.
