The Role of Telematic Practices in Computer Engineering: A Low-cost Remote Power Control in a Network Lab

Abstract

The present paper describes a practical solution of e-learning laboratory devoted to the study of computer networks. This laboratory has been proven with two groups of students from the University of Huelva (Spain) during two academic years. In order to achieve this objective, it has been necessary to create an entire network infrastructure that includes both the telematic access to the laboratory equipment and the remote power control. The interest of this work lies in an economical and simple system of remote control and telematic access with a twofold objective. On the one hand, to develop distance practices with attendance appearance by means of real hardware systems, not simulated. On the other hand, to reduce the power consumption regarding other proposals of remote labs with permanent power connection, providing herein an on demand connection only when required. As a result, a versatile and flexible laboratory has been put into practice whose basic network topology allows transferring traditional practices to telematic practices in a natural way and without harsh change

Exploring strengths and weaknesses: A case study after developing a remote network lab

“…The research undertaken for this project arises from the initiative of a team of teachers as part of a larger educational project, which has been extensively described in Ref. . The system proposed has been tested in a networking laboratory at the University of Huelva (UHU), Huelva (Spain) whose ultimate goal is to deploy an e‐learning laboratory in Computer Science to perform practices at distance with real hardware.…”

A Reproducible Solution for Implementing Online Laboratory Systems Through Inexpensive and Open-source Technology

“…Another remote lab study was performed by T.J. Mateo Sanguino et al (2012) at the University of Huelva in Palos de la Frontera, Spain. In this study a similar setup was implemented with a client providing user access to a remote server, which was in turn connected to a lab system.…”
