  1. StreamGlobe:P2P Stream Sharing Richard Kuntschke, Tobias Scholl, Bernhard Stegmaier, Alfons Kemper, and Angelika Reiser Fakultät für Informatik Technische Universität München Germany StreamGlobe

  2. Publish & Subscribe in a P2P Network StreamGlobe

  3. Traditional Approach without Stream Sharing • Deficiencies of traditional • approach: • Redundanttransmission ofdata streams • Redundant executionof stream transformingoperators • Transmission ofunnecessary data • Increased network traffic • Increased peer load StreamGlobe

  4. StreamGlobe Approach using Stream Sharing • Benefits of StreamGlobe • approach: • Stream sharingavoids redundantdata streamtransmissions • Sharing computationalresults avoids redundantcomputations • Early filtering andaggregation avoidunnecessary transmissions • Reduced network traffic • Reduced peer load StreamGlobe

  5. Vela Supernova Remnant RXJ0852.0-4622 Supernova Remnant Demonstration Outline • Publish & Subscribe to data streams in a Grid-based P2P Data Stream Management System • Optimization using data stream sharing • Prevention of overload situations • Throughput experiments • Various network topologies and scenarios • Real astrophysical data (ROSAT All Sky Survey (RASS) and others) StreamGlobe

  6. Demonstration Times Group 2: P2P Based Systems • Tuesday 14:00-15:30 • Thursday 14:00-15:30 StreamGlobe
