ICT-Project: Communication-Services-and-Security

This repository contains the exercises required during the subject 'ICT Project: Communication Services and Security' of the University of Lleida Master's degree in Informatics Engineering.

This is a repository for PRACTISING, INSPIRATION and to review the solutions of a previous year, as they should not be the same.

Give me a star ⭐ if you find it useful. You can contact me if any question.

Subject's extra information

The subject gives an overview of today's computer networks, dealing with their inherent congestion and mobility problems. At one hand, flow control, congestion and quality of service issues are studied, showing how requirements such as high demand, multimedia traffic and low delay are met.

At the other hand, wireless technologies are explained, from technical solutinos to security aspects, showing as well design and deployment issues, based on state-of-the-art technologies. Finally, its is shown how such a heterogeneous services (voice, data, video, ...) are integrated under a unique network architecture.

Learning Objectives

• To understand flow control mechanisms in current data communications networks
• To understand different quality of service mechanisms in current data communications networks
• To configure and test quality of service solutions in network devices
• To understand wireless communication technologies
• To understand and analyze security mechanisms in wireless communications
• To deploy and configure common communication services: authentication, DNS, DHCP, VoIP, ...
• To design, configure and test wireless deployments
