  1. 1. Socio-Economic Services for European Research ProjectsFuture InternetArchitecture Group Simple Economic Management Approaches of Overlay Traffic in Heterogeneous Internet Topologies Design Principles for Future InternetIoanna Papafili, AUEBGeorge D. Stamoulis, AUEBCostas Kalogiros, AUEB FIArch workshop,Sergios Soursos, ICOM Brussels, BelgiumKrzysztof Wajda, AGH May 23, 2011Burkhard Stiller, UZH © 2010 The SESERV Consortium 1
  2. 2. The Internet Ecosystem: Current and Future Many players acting simultaneously … – Customers/Users – Providers • ISPs • Application providers • Over-the-top providers • Content providers • … … with conflicting interests  leading to tussles © 2010 The SESERV Consortium 2
  3. 3. Cross-layer & Cross-player Application users/ Customers Applications Content Provider ISP n Physical network ISP 1© 2010 The SESERV Consortium 3
  4. 4. Information Asymmetry ISPs make routing decisions ignoring application requirements Applications (e.g. overlays) manage traffic do not take into account underlay characteristics What is needed? © 2010 The SESERV Consortium 4
  5. 5. FI Design Objectives Cross-layer optimization – Underlay-overlay Cross-player optimization – ISPs, Content Providers, End-Users Promotion of mutually beneficial cooperation – Among layers – Among players © 2010 The SESERV Consortium 5
  6. 6. FI Design Principles Allow the exchange of information among different players and layers Reveal only sufficient information, no critical details If feasible, enable “All-Win” – Provide incentives to affect stakeholders’ behavior Clark et al.: Do not dictate the outcome, … permit players to express their preferences © 2010 The SESERV Consortium 6
  7. 7. Economic Traffic Management developed by SmoothIT project (www.smoothit.org) Employs economic concepts and incentive-based mechanisms to promote collaboration across layers and between players Target: “All (stakeholders)-Win” situation ETM Focused on P2P traffic, but… applies also to CDN traffic, cloud etc. © 2010 The SESERV Consortium 7
  8. 8. Conclusion SmoothIT ETM mechanisms implemented as complements to current Internet architecture New design principles would allow: – Broader applicability – Richer intelligence – Higher efficiency in • performance • implementation • scalability – Lower costs © 2010 The SESERV Consortium 8

  12. 12. Challenges of Current Design Principles Address inter-connection aspects inherently in the design – Inter-connection principle Allow for more flexible modularization – Modularization principle Employ locality/proximity information besides pure routing information – Connectionless packet forwarding principle © 2010 The SESERV Consortium 12
