Introduction

ANT VLabs Research analysis manifest clear trends of growing interest of the Computer Science students towards e-learning. To keep this trend as well as the pace with the rapid advancement of software technologies the "Advanced Network Technologies Virtual Lab" has been developed. This lab expose the students to various advanced topics including Wi-Fi, WiMAX, MANET, WSN, and encourages them to work on related problems in a partially constrained environment. Apart from providing detailed theory on each topic, each "virtual" experiment in the lab has a set of exercises to be solved using remote network simulations. Network Simulator 2 (NS-2) and Network Simulator 3 (NS-3) have been used for this purpose.

This virtual lab also offer benefits such as reduced software and hardware costs for setting up an actual advanced network technology lab, improved learning by interactive visualization, and self-learning advanced network technologies in the absence of a real-life instructor. Additionally, the students can learn at their own pace any time and from any place which has a PC with high speed Internet connectivity.

Objectives

The Advanced Network Technologies Virtual Lab has been developed by keeping in mind the following objectives:

  • To impart state-of-the-art knowledge on advanced topics in Computer Networks in an interactive manner through the Web
  • Introduce the concept of network simulation to the students
  • Involve students in analytical studies of Computer Networks through network simulation

All the while it is intended to present Computer Networks as an interesting subject to the students where learning and fun can go alongside.

This lab is suitable for undergraduate (3rd year or above) or postgraduate students having a course on advanced topics related to Computer Networks.

Relevant Courses

Anna University Many universities in India, which offer UG/PG courses in CSE/IT, have a subject on advanced networks in their curriculum. Being an advanced level subject, there is a lack of consistency in the topical coverage across the curriculum followed in different universities on this subject. However, the set of experiments presented here match about around 50% of Anna University's B. Tech. (IT) subject "High Performance Networks". Other Universities Further, at least 70% of the experiments would help to reinforce the learning on different courses offered by many other universities, some of which are listed below.

PG Courses

  • M.Tech. (Networking) at Visvesvaraya Technical University
  • M.Tech. (CSE, IT) at Vellore Institute of Technology

UG Courses

  • B.Tech. (CSE) at Jadavpur University
  • B.Tech. (CSE, IT) at Rajasthan Technical University
  • B.Tech. (IT) at West Bengal University of Technology
  • B.Tech. (CSE, ECE) at Vellore Institute of Technology
