"Peer-to-Peer II - Methods" is a course for B.Sc. and M.Sc. students of Computer Science. The course is held as a combination of a lecture (TUCaN-no. 18-sm-2190-vl) and exercises (TUCaN-no. 18-sm-2190-ue).

The course organized in parallel to "P2P Systems and Applications" (18-sm-2110) for M.Sc. and diploma students of Electrical Engineering (and related study programs).

Course Description

Fully distributed systems, typically termed Peer-to-peer (P2P) systems, seem to be of much more interest these days, especially moving from a pure file sharing use to a more commercial use and application. While the more traditional Client/Server (C/S) system belongs clearly to the distributed system, many new applications tend to prefer in certain cases a P2P-based approach. This lecture addresses P2P topics including but not limited to:

• Distributed Hash Tables (Pastry, Chord, CAN)
• Hybrid Approaches (Gnutella 0.6, eDonkey)
• Selected Concepts (Bloom Filters, Hypercube, de Bruijn)
• P2P Incentives (Free Rider Problem, Game Theory Approach, Tit-for-Tat)
• P2P Accounting (Distributed Accounting, Virtual Currencies)
• Mobile P2P (Algorithms, Energy-efficiency Aspects, Mobile Testbeds)
• P2P Storage (Mechanisms, Applications)

Students will get a deep insight into advanced Peer-to-Peer methods and concepts. In this context, the lecture will cover fully distributed communication paradigms to describe and evaluate alternative approaches to the client-server model. By means of specific concepts and approaches the students will learn, in which way the Peer-to-Peer (P2P) paradigm shows benefits as well as drawbacks in specific environments.
