What?Content access and distributionInformation-Centric Networking (ICN)

tries to develop general infrastructure that provides in-network caching so that content is distributed in a scalable, cost-efficient & secure manner

• Receiver-driven model – subscribe/get objects of interest

• Support for location transparency, mobility & intermittent connectivity

• Needs also to be able to support interactivity (e.g. voice) and node-oriented services (e.g. telnet)

Robert Szabo (BME-TMIT) <robert.szabo@tmit.bme.hu> 3

Why?Users are interested in named

content and not in node endpoints It is done over the top in overlay

networks

Robert Szabo (BME-TMIT) <robert.szabo@tmit.bme.hu> 4

How?In network solution

similar to P2P/CDN-like paradigm

Robert Szabo (BME-TMIT) <robert.szabo@tmit.bme.hu> 5

Who’s Business?EU’s digital agenda

to push BWDeutsche Telekom,

France Telecom, Telecom Italia, Telefónica and Vodafone to see RoI

overhaul of the ISP peering system

Incentives?Why?

Users are interested in named content and not in node endpoints

• It is done over the top in overlay networksHow?

In network solution• similar to P2P/CDN-like paradigm

Who BUT the network operators?

Issues: NamingIDs for Information Objects

location-independent• all the object copies sharing a unique ID

Security applied to information• Non human friendly IDs

Name resolutions to IDs Search on object metadata

Figures Many more than the trillion URLs (10^12)

SCALING

Issues: RoutingName / ID Locator (two phase)

Allows incremental deploymentID based routing (one phase)

Radical changes to the arch.

Issues: SecurityPrivacy concern

network sees the objectCaching of illegal content

Potentials?Intelligent nodes

Network codingContent builds

from interactions Relationships & flows between

people, groups, organizations
