Be prepared to solve tasks by applying your knowledge to a variety of scenarios, covering all network layers and their interactions. For the exam you may bring along a one A4 page with notes as auxiliary material. Below you find the meta content of the exam.

Note: This lecture will only be held in English

Introduction

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.

Topics

This lecture explains the principles of computer networks based on the fundamentals of the area. The topics include network protocol mechanisms, implementation principles, network algorithms, advanced network architectures, network simulations, measurements and protocol specifications and verification techniques.
