Information-Centric FIA Budapest Robert Szabo 5 July 2011

What?  Content access and distribution  Information-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) 2 Robert Szabo (BME-TMIT)

Why?  Users are interested in named content and not in node endpoints  It is done over the top in overlay networks 3 Robert Szabo (BME-TMIT)

How?  In network solution  similar to P2P/CDN-like paradigm 4 Robert Szabo (BME-TMIT)

Who’s Business?  EU’s digital agenda to push BW  Deutsche Telekom, France Telecom, Telecom Italia, Telefónica and Vodafone to see RoI  overhaul of the ISP peering system 5 Robert Szabo (BME-TMIT)

Incentives?  Why?  Users are interested in named content and not in node endpoints It is done over the top in overlay networks  How?  In network solution similar to P2P/CDN-like paradigm  Who BUT the network operators? 6 Robert Szabo (BME-TMIT)

Issues: Naming  IDs 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 7 Robert Szabo (BME-TMIT)

Issues: Routing  Name / ID  Locator (two phase)  Allows incremental deployment  ID based routing (one phase)  Radical changes to the arch. SCALING 8 Robert Szabo (BME-TMIT)

Issues: Caching  In-network content caching 9 Figure: courtesy of George Pavlou MANAGEABILITY Robert Szabo (BME-TMIT)

Issues: Security  Privacy concern  network sees the object  Caching of illegal content 10 Robert Szabo (BME-TMIT)

Potentials?  Intelligent nodes  Network coding  Content builds from interactions  Relationships & flows between people, groups, organizations 11 Robert Szabo (BME-TMIT)

Projects?  UCB DONA - Data-Oriented Network Architecture  Xerox PARC CCN - Content-Centric Networking  4WARD/SAIL - Network of Information  PSIRP/PURSUIT - Publish Subscribe Routing  COMET - Content Mediation Architecture  ALICANTE - Content-aware Media Ecosystem  CONVERGENCE - Content-centric Service Model  COAST – Content-aware Search, Retrieval & Streaming 12 Robert Szabo (BME-TMIT)

Solutions: Content Centric Networking (CCN) Robert Szabo (BME-TMIT) 13

Solutions: Publish-Subscribe In- ternet Routing Paradigm (PSIRP) Robert Szabo (BME-TMIT) 14

Solutions: 4WARD-NetInf Robert Szabo (BME-TMIT) 15
