- 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
