Seminar Details

The seminar provides a broad overview on existing distributed system and current research topics in advanced areas of Internet technology. It is our paramount interest to see that you gain a thorough understanding of your seminar topic and that you are able to convey this understanding to the other participants. For you to benefit from the presented knowledge, we encourage active participation and interaction between students. You will both synchronize with each other while preparing your talk as some topics overlap and discuss the contents after the talks themselves.

Your contribution to the seminar is twofold: you present your topic concisely in a 30-minute talk to the other seminarists and you supply a paper providing more detail than the talk on the topic. Furthermore, you are expected to engage in discussions about each talk. Plagiarism of any form is unacceptable and will lead to your immediate suspension from the seminar. The recommendations at -> Teaching -> Seminar are a good starting point for designing and writing your slides and your paper. Please adhere to them to avoid disappointment when discussing your work with your supervisor.

In production of the seminar paper, we follow a "conferece organization style". That means: after the assignment of topics at the kick-off meeting, you have some time (5 - 6 weeks) to do a literature survey and to prepare a paper about the topic. You are submitting your paper like for a conference: it will be reviewed and you will get back comments for improvement of your paper. The reviewing process will also be done by the seminar participants, i.e. you have to write a review about two or three other seminar papers (and you also get feedback from two or three other students). Basing on the comments, you have to prepare the final version of your seminar paper and afterwards a presentation, too.


The goal of the talk is to give the audience a good understanding of the whole topic and to dive into a few interesting details of the subject matter. The ratio of one to the other depends on the topic and needs to be determined with your supervisor. Each talk is scheduled to be 30 minutes, with 25 and 35 minutes being hard lower and upper bounds, respectively. Ten minutes of discussion follow each talk.


While the talk focuses on the overview and details of interest, the paper allows you to discuss your topic in its full breadth and depth. It covers all aspects of the talk and provides additional insights to related work and specifics. For example, source code snippets or interface descriptions would not go into your talk but may well show up in your paper where applicable.

The papers are based on the official ACM conference style and are expected to be between eight and ten pages in length (hard limits). ACM provides official templates for a number of formats but we encourage you to use LaTeX for writing your paper.


To paticipate in the seminar, you should have some preknowledge on Internet technology. That is, you should have attended a lecture on data communications (or, in case of Bachelor students, "Sichere Verteilte Systeme") and/or one of the lectures "Advanced Internet Technology" / "Mobile Communication and Sensor Networks". In case you have not attended one of these lectures but nevertheless some knowledge about Internet technology from other sources, participation is also possible.
