  1. Information-Centric Networking @ FIA Budapest Robert Szabo 5 July 2011

  2. 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) 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 BW • Deutsche Telekom, France Telecom, Telecom Italia, Telefónica and Vodafone to see RoI •  overhaul of the ISP peering system Robert Szabo (BME-TMIT) <robert.szabo@tmit.bme.hu>

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

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

  8. Issues: Routing • Name / ID  Locator (two phase) • Allows incremental deployment • ID based routing (one phase) • Radical changes to the arch. SCALING Robert Szabo (BME-TMIT) <robert.szabo@tmit.bme.hu>

  9. Issues: Caching • In-network content caching MANAGEABILITY Figure: courtesy of George Pavlou Robert Szabo (BME-TMIT) <robert.szabo@tmit.bme.hu>

  10. Issues: Security • Privacy concern • network sees the object • Caching of illegal content Robert Szabo (BME-TMIT) <robert.szabo@tmit.bme.hu>

  11. Potentials? • Intelligent nodes • Network coding • Content builds from interactions • Relationships & flows between people, groups, organizations Robert Szabo (BME-TMIT) <robert.szabo@tmit.bme.hu>

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

  13. Solutions: Content Centric Networking (CCN) Robert Szabo (BME-TMIT) <robert.szabo@tmit.bme.hu>

  14. Solutions: Publish-Subscribe In-ternet Routing Paradigm (PSIRP) Robert Szabo (BME-TMIT) <robert.szabo@tmit.bme.hu>

  15. Solutions: 4WARD-NetInf Robert Szabo (BME-TMIT) <robert.szabo@tmit.bme.hu>
