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
