  1. Delay Tolerant Networking Research Group 60th IETF Kevin Fall, chair Intel Research, Berkeley http://www.dtnrg.org Aug 6, 2004

  2. Goals of this Meeting • Introduce new people • DTNRG problem overview • State of the RG • Share research efforts/experience • Update/evaluate our status • IETF Documents • Future directions?

  3. DTNRG is looking at… • Radical heterogeneity • Layer-agnostic interconnection of networks (IP and non-IP) • Tolerance to disruption/disconnection • No contemporaneous e2e path assumed • “Advanced” (multi-path) routing • Similar to multi-commodity flow or trans-shipment problem in operations research

  4. DTN Architecture Highlights • Asynchronous messages (bundles) • Two-part naming with late binding • Enhanced reliability via custody transfer • Routing with fragmentation • Predicted and opportunistic connectivity • (Security for infrastructure protection) • (Flow and congestion control)

  5. Very Brief History • DTNRG Chartered as IRTF research group (end of 2002) • Architecture evolved from deep-space-focused Interplanetary Internet project • Funded by DARPA 1999-2002 • IRTF Group IPNRG retired when DTNRG formed • Currents: • IDs on arch, proto, IPN mapping • Implementation, DARPA program, papers, etc

  6. Output • Papers: • SIGCOMM 2003 – Architecture • SIGCOMM 2004 – DTN Routing • IEEE Communications – DTN for IPN • SpaceOps – DTN for Mars Exploration • Software: • Code released Mar. last year • Public CVS available + new implementation • Real-world use: • Not much yet: ICT4B Project, others? • Other: • basis for DARPA DTN Program

  7. Agenda [1] • Early afternoon talks: • Intro (me) • Mindstream (Keshav, U Waterloo) • Firefighting in San Diego (hwb, SDSC/NLANR) • SNC Project (A. Doria, Lulea/KAIST) • (break)

  8. Agenda [2] • Late afternoon talks: • Routing in a DTN (S. Jain, UW) • DTN Reference Implementation (M. Demmer, UCB) • UCLA DTN-Sensor Projects (A. Parker, UCLA) • LTP and SenDT (S. Burleigh, JPL and S. Farrell, Trinity) • Drive-Thru Internet (Joerg Ott, Uni-Bremen) • Wrap-up (all)
