Title: Teaching Experiences With a Virtual Network Laboratory
Authors: Ken Wong, Tilman Wolf, Sergey Gorinsky, and Jonathan Turner
Abstract: The Open Network Laboratory (ONL) is an Internet-accessible
virtual laboratory facility that can deliver a high quality laboratory
experience in advanced networking [3,7]. 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.
