  2. Mobile Data Traffic Prediction From 2010 to 2015: factor 26 increase expected IRTF Open Meeting @ IETF-81

  3. Video Data Traffic Prediction From 2010 to 2015: factor 5 increase expected IRTF Open Meeting @ IETF-81

  4. Popular Conception:Content Distribution Over the Internet Does Not Scale Tier 1 Networks ISPs IRTF Open Meeting @ IETF-81

  5. Problems with Today’s Networks • URLs and IP addresses are overloaded with locator and identifier functionality • Moving information = changing it‘s name => 404 file not found • No consistent way to keep track of identical copies • No consistent representation of information (copy-independent)‏ • Information dissemination is inefficient • Can‘t benefit from existing copies (e.g. local copy on client)‏ • No “anycast”: e.g., get “nearest” copy • Problems like Flash-Crowd effect, Denial of Service, … IRTF Open Meeting @ IETF-81

  6. Problems with Today’s Networks • Can’t trust a copy received from an untrusted node • Security is host-centric • Mainly based on securing channels (encryption) and trusting servers (authentication)‏ • Application and content provider independence • CDNs focus on web content distributions for major players • What about other applications and other players? IRTF Open Meeting @ IETF-81

  7. Information Centric Networking Information Centric Network Focus on informationobjects Today’s Internet Focus on nodes In today’s Internet,accessing information isthe dominating use case! Evolution Web CDN P2P • Considering important requirements • Accessing named resources – not hosts • Scalable distribution through replication and caching • Good control of resolution/routing and access • With ubiquitous caching • But for all applications • And for all users and content/service providers IRTF Open Meeting @ IETF-81

  8. Why an IRTF Effort Would be Useful • Topic seems important – quite some interest • Content-distribution perspective • Internet evolution perspective • Quite a number of research projects • Beneficial to bring people together in an IRTF/IETF context • Internet development expertise considered important • Related to on-going IETF efforts • PPSP, DECADE, CDNI • RG for persistent activity • Different than typical conferences, workshops etc. IRTF Open Meeting @ IETF-81

  9. Possible Research Topics • Naming schemes for ICN • Scalable name resolution for flat names • Scalable routing schemes • Security and privacy • Application/application-protocol design • APIs • Business, legal and regulatory framework • Internet evolution / migration IRTF Open Meeting @ IETF-81

  10. ICNRG current status • Well attended bar meeting in Prague • ICN-interest mailing list: 130 subscribers • Positive feedback from all research projects in the area (that we heard from) • Initial contacts with IRTF chairs Aaron Falk (previous) and Lars Eggert (current) – positive feedback • The ICNRG proposal was discussed at a side meeting Tuesday in Quebec • Charter proposal on IRTF Wiki • Planning group • Bengt Ahlgren, Stephen Farrell, Volker Hilt, Dirk Kutscher, Börje Ohlman, Jörg Ott, Martin Vigoureux, Lixia Zhang IRTF Open Meeting @ IETF-81

  12. ICN Community Forming • Dagstuhl seminar onInformation-Centric Networking; Dec 2010 • SIGCOMM-2011 Workshop on Information-Centric Networking; August 2011 • IEEE Communications Magazin Special Issue on ICN • CfP open now • Elsevier Computer Communications Journal 2012 • CfP to be published • ICN Interest Mailing List • https://listserv.netlab.nec.de/mailman/listinfo/icn-interest ICN side meeting @ IETF-81 12
