1. UNIVERSITY OF JYVÄSKYLÄ P2PStudio – Monitoring, Controlling and Visualization Tool for Peer-to-Peer Networks Research Presentation for PM 2 HW 2 N on 2 Oct 2006 Niko Kotilainen, research assistant Department of Mathematical Information Technology University of Jyväskylä, Finland http://tisu.it.jyu.fi/cheesefactory With co-authors Mikko Vapa, Annemari Auvinen, Matthieu Weber and Jarkko Vuori

2. UNIVERSITY OF JYVÄSKYLÄ 2006 Presentation Overview Peer-to-Peer networks Chedar Peer-to-Peer Network Peer-to-Peer Studio –Structure –User interface demonstration

3. UNIVERSITY OF JYVÄSKYLÄ 2006 Peer-to-peer (P2P) network Distributed network –No central servers –The peers are equal –All peers can act as clients and servers. Fault tolerant

4. UNIVERSITY OF JYVÄSKYLÄ 2006 Chedar Peer-to-Peer Middleware CHEap Distributed ARchitecture Developed by our research group Cheese Factory Currently used in P2P Networks research and for distributed computation of demanding tasks.

5. UNIVERSITY OF JYVÄSKYLÄ 2006 Peer-to-Peer Studio Used to control the Chedar network. Can also be used offline to visualize networks. A monitoring, controlling and visualization tool for P2P networks research. Uses a centralized architechture.
