A Virtualized Network Teaching Laboratory
2009 Annual Conference & Exposition Proceedings
Since for most students, learning dramatically improves with hands-on experience, a good networking lab is an asset for teaching networks. However, building such a lab is usually a challenge. It requires costly equipment and flexible configurations that are often not compatible with the campus network. In this paper, we describe how we designed a network teaching lab based on virtual machines connected on a virtual network. An instructor can create a virtual network and make it available to students. Students can configure the network and run experiments as instructed. When the task is complete, the students can submit the result of their work.
Creating a virtual network laboratory
Proceedings of IEEE International Conference on Multimedia Computing and Systems, 1997
Net.working technologies have entered an unprecedented era after the explosive growtr of the Internet and the roll-out of high speed networks. This paper addresses the concept of using exis1 ing multimedia and computer networking technologies to create a remotely accessible, virtual network laboratory that can expand student access and eliminate many of the time, geographical, and cost constraints that currently exist. The authors propose a framework for constructing lab modules for a virtual network laboratory. A prototype has been developed for a series of Java-based modules that allow students to access and interact with the virtual laboratory databases and physical networking devices in a user-friendly manner. It provides a demonstration of networking concepts by usinf; the developed materials in new courses at each of the participating universities.
Teaching experiences with a virtual network laboratory
2007
The Open Network Laboratory (ONL) is an Internet-accessible virtual laboratory facility that can deliver a high quality laboratory experience in advanced networking 7]. Our experience with ONL indicates that it has potential to improve student understanding of fundamental networking concepts and increase enthusiasm for experimentation with complex technology. Furthermore, these benefits can be delivered with less effort from the instructor than using a traditional approach of socket programming and ns-2 simulation exercises. The system is built around a set of high-performance, extendible routers which connect personal computers acting as end systems. Users configure their virtual network through the Remote Laboratory Interface (RLI), an intuitive graphical interface. The RLI's realtime charts and user data facility make it easy to directly view the effect of system parameters on traffic behavior. These features can enhance learning by providing users with multiple representations of network phenomena. We describe how the ONL facilities have improved our ability to meet instructional objectives and discuss some approaches to improving the laboratory experience.
A virtual network laboratory for learning IP networking
ACM SIGCSE Bulletin, 2002
In this paper, a network laboratory for distance learning of basic concepts in IP networking is presented. Through a web interface, students can choose various configurations of a real private network (number of routers and subnetworks, use of IPv4/IPv6, etc.), and learn about them using Linux network commands. The utilization of the virtual laboratory and how it is implemented are described.

An increasingly connected society demands people who can design, set up, monitor and maintain networks of computers and devices. Traditional classroom instruction cannot keep pace with demand, and networking hardware costs can be too high for widespread classroom use. This paper presents the Open Networking Lab, a new UK initiative for supporting handson vocational learning in computer networking. The Open Networking Lab will facilitate the development of introductory practical networking skills without using hardware, through the provision of a web-based network simulation package integrated into learning resources and activities. These learning resources will be evaluated by students and lecturers from a cluster of Further Education colleges in the UK and will subsequently be made available to learners worldwide via free and open courseware. Keywords—vocational learning; further education; computer networking; network simulation.
Teaching computer networking with the help of personal computer networks
ACM Sigcse Bulletin, 2004
User Mode Linux is a virtual machine running on a GNU-Linux operating system. It is the right choice for teaching operating systems' administration, as it does not need any dedicated hardware. It runs at user level (no need for root, i.e. administrator, access or possible security threats) and it does not have the performance problems of an emulator. This paper describes how to set up a laboratory for teaching operating systems' administration.
