Course purpose

Introductory course on data communication and computer networks/Internet, including (i) aspects that practicing engineers encounter in their work, as well as (ii) context for following upon the evolution of this rapidly changing field of computer science and engineering, e.g. Internet of Things. After completion, the student should be able to distinguish the different network layers, services and related protocols. In particular, students will be able to:

• Explain the major tasks/services that each of these provides
• Explain possibilities and constraints in today's networks (Internet) and in general contexts
• Build and configure a working network 

Moreover, via the labs and assignments, students will be trained in solving network problems, working with network protocols, building up a network and configuring (also dynamically) network traffic; they will also have gained experience by doing practical work in applying the knowledge offered by the course in realistic situations.

In the study of protocols, we start with application-layer protocols, in the context of applications that we use regularly. Moving to lower layers later on, we have the possibility to gradually uncover network services, their functionality and the ease/difficulty for achieving them. Topics covered include: networking applications, content distribution, HTTP, SMTP, TCP, UDP, performance and congestion analysis, IP, switching, routing, Software-Defined networks (SDN), mobile IP, local area networks, multiple access protocols (IEEE 802.X and others), wireless networks; in less detail we discuss physical media, error-detection and correction, and network security, connecting to other courses that specialize on these subjects.
