Many players acting simultaneously …
– Customers/Users
– Providers
• ISPs
• Application providers
• Over-the-top providers
• Content providers
• …
… with conflicting interests leading to tussles

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?

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

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

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.

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

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
