All lectures and labs are only available online. Therefore there will be no information session with the sign-up for the laboratory presently. Depending on further developments we plan to run this lab towards the end of the term as block modules. I will inform you about this on the website and Studip.
To provisionally sign up for the lab please visit Studip and sign up for the desired lab. Due to the existing regulations the number of participants may be limited for certain labs.

Professor Liebeherr visits the Internet Lab
Prof. Liebeherr, one of the authors of the well-known "Mastering Networks" laboratory manual, visited the Institute of Computer and Communication Network Engineering at the University of Technology of Brunswick. Prof. Liebeherr actively interacted with the students and listened to their impressions about the lab material. He also used this opportunity to explain more about the reputation this lab enjoys in the US academic institutions and in the industry in general. At the present, Prof. Liebeherr is Professor at the University of Toronto in Canada where the Internet Lab is highly sought by students.
Description of the Internet Lab
The explosive growth und the ubiquitous use of the Internet has created a need for scientists and engineers, who can maintain, debug, and innovate the Internet infrastructure. The goal of this lab is to provide a deep understanding of the protocols and algorithms underlying to the Internet. Among others, this will cover principles of addressing, routing, error control, flow- and congestion control, as well as performance evaluation. As there is today an increasing need for hands-on experience, the students use existing network hardware to create own network examples and receive by real observations of the network traffic a deep insight and an extensive understanding about the functional way of the Internet. In this way the lab transfers theoretical network knowledge acquired in the lecture Communication Networks into practical experience.

Structure of the labs
Each lab encloses the following partial tasks:
Prelab: Exercises to be completed in advance of the associated lab session.
Lab session: All lab exercises can be completed without supervision. During the lab session the network infrastructure has to be configured. Result data are to be collected.
Lab Report: For each lab session a lab report has to be prepared, that summarize and analyze the findings and questions from the lab session.
