Objectives

The goal of this course is to provide students with competences in the area of content distribution in computer networks, including multimedia, and on how an IP network can support quality of service for different content types. In this context, network neutrality will be introduced and discussed.

 

Learning outcomes and competences

At the end of the course, students will be able to 

• design and configure an email infrastructure in an enterprise network, 
• dimension and analyse the performance of a global web content delivery infrastructure, 
• evaluate and improve the performance of multimedia content delivery systems, 
• analyse, design and configure quality of service mechanisms in IP networks

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Knowledge in data communication networks, including principles and concepts of network architectures, main networking technologies and solutions in use, TCP/IP protocol stack, common networking tools, including wireshark, programming and Linux OS.
