1. Introduction

The widespread diffusion of Internet has led to the burgeoning growth of distance education, which has provided enormous opportunities for people who wish to further their education. Distance education is a planned teaching/learning experience that uses a wide spectrum of technologies to reach students at a distance. It is designed to encourage students to remotely interact with educators and other students. Critical elements of distance education include access, technical design, virtual environment, interactions within the community, etc.

Distance education through online courses is becoming a widespread standard offered by most universities at both undergraduate and graduate level. Online courses are typically delivered to students via some sort of asynchronous tools, such as bulletin boards, video streaming, email, and web based course assignment submission systems, etc. Some courses may contain a synchronous component with chat facility. Blackboard and WebCT are popular examples. Their main functionalities may include synchronous and asynchronous communication, electronic whiteboards, email, web pages, and calendars. However, these tools show inability to deliver hands-on learning opportunities when used in courses with lab practice.

As an integral part of online networking courses, a remote network lab benefits students in multiple ways. First of all, it strengthens students’ understanding of the network concepts in a practical way. Theories of network protocols and architectures are abstract and monotonous for those students without any prior network experience. Active involvement in the laboratory can ignite their interest and give them a “big picture” of the functionality of a network and its
