Presentation Transcript

  1. Online Social Networks, Future Internet Design, and Research Experimentation S. Felix Wu Computer Science Department University of California, Davis wu@cs.ucdavis.edu http://www.cs.ucdavis.edu/~wu/

  2. Davis Social Links (DSL) • A NSF FIND project • Looking for a research testbed to both experiment and attract potential users for our prototype

  3. Social-Control Routing Applications with Tests 3 2 1

  4. My message to Salma

  5. The Social Path(s)

  6. More Examples

  7. The value of the “Network” • A concern about a network losing its “value” • while we are unsure about how to quantify the true value… • Social Capital or Utility

  8. Trust Structure as the Utility We want to stabilize these decentralized values such that they can be used to effectively choose the “best” route.

  9. Pkt[c>d] A B C D Trust(B>A) Trust(C>B) Trust(D>C) Pkt[ab] Pkt[abc] Pkt[bcd]

  10. Routing with Trust

  11. Orkut (15329 nodes)

  12. The Issue of “Value” • What is the “value” of this social network? • How would this “value” be distributed and allocated to each individual peers? • MySpace, Facebook, LinkedIn didn’t define the “game” for network formation and value allocation. • But, it is important to design the game such that the OSN will eventually converge to a state to best support the communities.

  13. Social Network Games

  14. Fighter’s Club • A Coalition game ~ like Warcraft • Team members who are Facebook friends receive higher fighting powers • ~1400 new friendships established daily • ~10% of users with >95% friendships purely based on this game.

  15. DSL as a Facebook Application • When you send a message… • Via Facebook • Via DSL • Activity and Intensity hiding via Decentralization! DSL Facebook

  16. DSL, Facebook, AL-BGP and GENI http://www.geni.net/DSLport AL-BGP over GENI/PlanetLab Each DSL/FB user should select a “closer” GENI entrance as www.geni.net. In other words, we might need to set up DNS records correctly. Facebook

  17. Social-Control Routing Applications with Tests 3 2 1

  18. GENI Requirements • Decentralization for Scalability • Decentralized Network Access to GENI • Computing/Storage Resources on the Nodes • Virtual Separation for Community-Oriented Networking • Workload Traffic Regeneration • TCPopera, BGP interactive replay • Anonymity support

  19. What we like to have… • A Decentralized Infrastructure and applications to attract large quantity of real active users • An secure/trustable/repeatable research experimental environment protecting the privacy of those real users (and activities)

  20. DSL Project Status • Right now ~50 users, and going to… • ecs30b (100+, fall’08), ecs251 (30+, winter’08) • Planning for Community-Oriented IT Campus • Summer 2009 for Facebook push • Building the user-base • Collaboration with Facebook and other OSN providers • Summer 2010~2012 • Decentralization and GENI port • DSL on Bicycle-MANET

  21. Activities, Knowledge Sharing, and Social Relationship Scalability, Privacy, Trust, Robustness, Performance…
