Presentation Transcript

  1. Active Applying active networks to traditional protocols Austin Clements Park City High School Patrick Tullmann, Jay Lepreau University of Utah Flux Research Group

  2. Focus • Real application, real protocol • Identify exploitable properties • Doom-specific in-network processing

  3. Doom • Multi-user, peer-to-peer, interactive simulation

  4. Doom Topology

  5. Properties of the Protocol • Game engine requirements: totally ordered, reliable, complete update stream • Implementation: unicast • Lock-step nature • Reliability is vital • Low-latency is vital

  6. In-network Processing • Application aware servers • In-network application-level totally ordered multicast • Aggregation • Compression

  7. Active Doom Topology

  8. Evaluation and Conclusion • Scalability • Bandwidth • Latency Initial results • Simulation: • Factor of <# of clients> decrease in sent data • 38% less data, due to compression • Implementation: 4x increased update rate

  9. Evaluation and Conclusion http://www.cs.utah.edu/flux/ Initial results • Simulation: • Factor of <# of clients> decrease in sent data • 38% less data, due to compression • Implementation: 4x increased update rate
