Abstract: The goal of the seminar is to examine peer-to-peer technologies, systems and applications, and to identify key research issues and challenges that lie ahead. Famous projects/products will give us a sense of what actual peer-to-peer systems look like and how they behave.

Synopsis:- Seminar, Praktische Informatik, Hauptstudium / Master-Programm.
- 1 meeting each week; for one semester (2 SWS).
Policies: - Attend regularly!
- You are allowed to miss at most one seminar without prior and reasonable excuse.
- Work in teams!
- Each of the topics below should be investigated by a group of 2-3 students. This means that you have to join more than one group, i.e. investigate more than one topic, during the seminar.
- Each group should meet outside class at least once to discuss findings, compare arguments and compose a presentation strategy.
- Do your own investigations!
- Use additional resources on the web - the suggested papers are only a jump start.
- Try to find opposing arguments - this makes research interesting :-)
- Present at least twice!
- Members of an investigation group present their findings together, or, choose one speaker.
- You can always improve your presentation style. Dare to experiment with different styles and choreographies. The audience will give you constructive feedback at the end of each seminar (Bewertungskriterien-Seminarvortrag).
- Each student must present at least 2 times during the semester (i.e. 2 different topics) to obtain credits (Seminarschein).
- A PowerPoint template can be obtained here.
Prerequisites: - Basic knowledge of network protocols, database systems and operating systems principles required.
- Almost no programming skills required - but won't hurt either.
