The SAIL Project

(Scalable & Adaptive Internet Solutions)

• EU Call FP7-ICT-2009-5

– 25 partners – 30 months duration – 12.4 M€ EU funding in 2.5 years (total ~20M€)

• SAIL‘s main objective

– Design concepts and technologies for the networks of the future – Develop techniques to move from today’s to future networks

Value Network Configurations of Information-centric Networking

Motivation: Identifying common roles in ICN and their strategic and economic value to the different actors to

• originally: compare success possibilities of different VNCs
• now also: recognize the potential tussles rising from

conflicting stakeholder interests

VNC terminology 1/2

• Technical architecture describes the technical

implementation.

– Technical component is a collection and realization of technical functionalities. – Technical interface presents the technical relationship (e.g., protocols or radio interfaces) between components.

VNC terminology 2/2

• Value network configuration results as actors take on

roles and establish business interfaces among each other.

– Actor is any person or organization, which has an interest in, provides resources for, or is affected by the use case. – Role is a set of activities and technical components, the responsibility of which is not divided between separate actors. – Business interface presents a business relationship (e.g., contracts and transactions) between actors.

Research question

• What are the possible VNCs that could emerge around

Information-centric content delivery?

– ICN understood widely: caching + focus on content, not location – Use case: content delivery from content provider to end-user

• Covered architectures

– CDN: Akamai CDN, Tier-1 ISP CDN, Google Global Cache – P2P: BitTorrent, Voddler, Spotify – Novel ICN proposals: NetInf, CCN/NDN, PSIRP, DONA

• Key objective

– Identify and describe common key roles and their value drivers

Localized CDN – Overview

Benefits

– ISP: savings in transit costs and network resources – End-users: lower latency – CPs: better QoE for end users; savings in CDN costs?

Potential tussles

• ISP-CP: Transit costs vs. Content freshness tussle

– In order to reduce transit costs, ISP may have limited interest in providing the most updated/fresh content

• ISP-CP: Access control tussle

– Providing cached content, ISP could serve the content request without informing CP so that end user would not be charged for it

• ISP-CP: Content usage statistics tussle

– Information popularity and other content usage statistics are hidden from original source and ISP may not have incentive in providing them

• ISP-CP-Regulator: Net neutrality tussle

– ISP may favor content of some CP over content of other CPs

• Conclusion: Business case may be negative for CPs
