Evaluation of network construction exercise system LiNeS on the basis of heterogeneous and distributed virtual machine network composition function

We have developed a system called LiNeS to facilitate exercises with virtual machines in the existing computer laboratories of universities. We achieved this by establishing a method for constructing a virtual network consisting of heterogeneous virtual machines, and another method for constructing overlay networks consisting of virtual networks on each PC; in addition, we developed several functions for supporting exercises. In this study, we evaluated LiNeS in experiments that students performed with actual machines and with LiNeS, with the help and supervision of assistants.
