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

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?

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

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

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.

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

11. Generic Design Objectives
 Genericity
 Scalability
 Robustness/Stability
 Security
 Simplicity and Cost-Effectiveness

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
