 Peer-to-Peer Networks
(Seminar 2 SWS)

Instructor: Prof. Jens-Peter Redlich
Thursday, 13:15 - 14:45, RUD 25, Room 3.101


Computer Science Department
Systems Architecture Group

 
Abstract: The goal of the seminar is to examine peer-to-peer technologies, applications, and systems, 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. In the context of this seminar, peer-to-peer systems are characterized as being decentralized, self-organizing distributed systems, in which all or most communication is symmetric.
 
Synopsis:
  • Seminar, Praktische Informatik, Hauptstudium.
  • 2h each week, over one semester (2 SWS).
  • Participants present a selection of recently published papers that will, through discussion, provide us with a deep understanding of the state-of-the-art in peer-to-peer network technology.

Credits and grading:

     In order to obtain credits for this seminar, participants are expected to:

  • Attend regularly (at least 90%).
  • Read each paper before the seminar, to be adequately prepared for discussion.
  • Research an assigned subject; present major findings (45 min presentation; 30 min discussion).
  • Presentations will be evaluated by two members of the audience at the end of each class (Bewertungskriterien-Seminarvortrag.pdf).
  • Presenters summarize their presentation and relevant discussion on the Seminar's WIKI page within 2 weeks.
  • Presentations may be given in English or German. All documents are in English (exceptions may be granted). A PowerPoint template can be obtained here.

Prerequisites:

  • Successful completion of PI-1,2,3.
