Nearly everybody knows and uses communication networks such as the Internet. As a computer scientist we even know how the Internet works in theory and we are able to distinguish applications like www, file transfer, e-mail as well as the related protocols. But how is the implementation realized in practice? And how do emerging paradigms such as Software-Defined Networks and network virtualization change the scene?
In this lab course (Praktikum) we will examine how routers and switches can be configured and connected to a working IP network. We will also cover software-defined and virtualized switches (e.g., Open vSwitch) as well as programmable data planes. We will carry out experiments with actual hardware and software network components. The experiments start with an introduction into the handling of the components and range from packet forwarding and routing over packet filtering, traffic shaping and VPN's up to principles of access networks. Furthermore, performance issues and network condition monitoring can be looked into.
Goal of this lab course is to intensively become acquainted with the workings of internet components, and a deep understanding of the underlying protocols. Attentive participation in this lab course is a perfect foundation for doing projects or master theses in the area of computer networking.
