Title: Operational Experience with a Virtual Networking Laboratory

Authors: Charlie Wiseman, Ken Wong, Tilman Wolf, and Sergey Gorinsky

Abstract: Virtual laboratories are a potential replacement for standard laboratory facilities that can reduce cost and maintenance overheads for teaching institutions while still ensuring that students have access to real equipment. Previous work indicates that students respond well to such environments, but one important operational aspect has been overlooked. In this work, we consider instructor overhead by comparing the amount of work required to teach courses with and without the use of a virtual laboratory. In particular, we examine two graduate computer networking courses, each taught with the standard software-only approach and then taught later with the Open Network Laboratory. Our data show that the effort required by the instructor to use a virtual laboratory is not much more than in a software-only environment, and that the increased interaction between student and instructor can be beneficial as the student questions are primarily focused on fundamental networking concepts.
