Practical Internet eXperience (PIX)

In this bachelor lab, students will build a mini-Internet by configuring routing protocols like OSPF and BGP and implement a transport protocol based on a provided specification. The course emphasizes practical skills in networking, software development, and teamwork, with a focus on testing and performance evaluation.

Proseminar on Networks & Security

This proseminar explores key topics in communication networks with a focus on Security & Privacy, covering both enduring research and emerging trends. Participants will work in pairs to write, review, and present scientific papers while attending preparatory lectures and a literature research course.
