Conceptual Model SEEDING SERVER ACCOUNTING SERVER DRM SERVER META SERVER SERVICE LAYER BACKBONE NETWORK CONNECTIVITY LAYER MANAGEMENT SUPER NODE SUPER NODE SUPER NODE ISP ISP ISP ACCESS LAYER . . . . . . . . . PEERS PEERS PEERS • Future Multimedia Framework • Legal Content • SIP2P competes • Why use SIP2P? • Seeding Server • Accounting Server • DRM Server • Meta Server

  5. Competitiveness NGN SIP2P P2P • HYPOTHESIS • SIP2P will only prevail if it offers higher utility to both peers and service providers than traditional streaming services, given the same quality level

  6. Economic Analysis • Peer's utility (u) αInducement factor βOpportunity cost factor u Utility v Price Key equations • Low Opportunity cost of underutilised resources • Inexpensive to increase utility • Cut-over • Explains current P2P

  7. Economic Analysis • Service Provider's cost (C) q License fee O Operational Cost γDepreciation factor I Investment αInducement factor Key equations TRAD • Profit maximising • Same functionality • Same cost • Different Investment TRAD profit SIP2P Unit Cost α Total Cost User reward SIP2P Number of users Number of users

  8. Simulation Service TRAD • 5.000 Investment pr. concurrent user • TRAD server has capacity of 100 • SIP2P server has capacity of 20 • Profit / Reward must be adjusted SIP2P α Total Cost Number of users

  9. Conclusion • Sever Initiated Peer-to-Peer (SIP2P) • Hybrid of Client/Server and Peer-to-Peer • Increases user’s utility • Decreases service provider’s cost • Split Profit / Reward • Decreases total cost • Is it bandwidth efficient? • Do users react to small rewards? • Is it technically possible • Which cooperative platform to use TRAD Unit Cost α SIP2P Number of users TRAD profit SIP2P Total Cost User reward Number of users
