LiNeS: Virtual Network Environment for Network Administrator Education

User-mode Linux (UML) is virtual environment software being developed for server integration, testing buggy software, and so on. However, we have been applying UML to network administrator education, since it has functions for comprising networks. The Linux Network Simulator (LiNeS) is a system that provides an environment for various network training based on virtual networks realized by UML on one PC. Since LiNeS does not require many network machines, unlike conventional network training, we believe that it can become a new learning method in network administrator education.
