Data Networks

In this lecture, we will discuss the structure of the internet including the basics of internet communication. We will start at the application layer and investigate services like web (HTTP), mail (SMTP, POP, IMAP), domain name systems (DNS), or routing (BGP). After that, we will work through the transport layer (TCP, UDP) down to the network layer (IP). Lastly, we will examine the interactions between the protocols. We further explain the principles of computer networks based on the fundamentals of the area, including network protocol mechanisms, implementation principles, network algorithms, advanced network architectures, network simulations, measurements, protocol specifications, and verification techniques.

This course is worth 9 LP/ECTS points. In compliance with the current COVID-19 measures, we provide structured recordings of two weekly lectures as well as a weekly Q&A session. Students are required to solve weekly assignments in small groups to qualify for the final exam. We, further, provide a weekly tutorial session.
