  1. Update on the Internet Research Task Force Aaron Falk IRTF Chair IETF-76 – Hiroshima

  2. IETF-76 -- Hiroshima IRTF Meetings • Four Research Groups (RGs) are meeting this week • Host Identity Payload RG • Scalable, Adaptive Multicast RG • Delay Tolerant Networking RG • Routing RG • Reviewed the RRG with the IAB

  3. IETF-76 -- Hiroshima IRTF RFCs • 0 IRTF RFCs published since last IETF • 6 docs waiting • Publication is wedged on finalizing IETF Trust License • Expected around end of the year • draft-irtf-rfcs-05.txt revised, now in RFC-Editor queue • Consistent with Independent Stream publication rights language (draft-braden-independent-submission-02.txt)

  4. IETF-76 -- Hiroshima New Work • Network virtualization • Bar BoF tonight, 1730 – 1930, Castleview 1 • Discussing a draft RG charter • Internet of Things/Smart Objects • Some interest in an RG, perhaps around architecture • Will be careful about not interfering with SmartGrid work (if any)

  5. IETF-76 -- Hiroshima RG Energy Levels Active Quiescent E2ERG NMRG TMRG PKING • ASRG • CFRG • DTNRG • HIPRG • ICCRG • MOBOPTS • P2PRG • RRG • SAMRG

  6. A brief introduction to a couple of research groups…

  7. Anti-SpamResearch Group

  8. IETF-76 -- Hiroshima What is the ASRG? • Open membership for anti-spam research • Look at open problems • Perhaps suggest areas for standards • People: some industry, some academic, many independent

  9. IETF-76 -- Hiroshima What isn't the ASRG? • Not a working group (see DKIM) • Not a trade group (see MAAWG, ESPC) • Not a conference series (see CEAS, Usenix, ...)

  10. IETF-76 -- Hiroshima Successes to date • RFC on details of DNS black/whitelists • In RFC Ed queue • Draft on blacklist management • Authors waiting to see if prior RFC ever gets published

  11. IETF-76 -- Hiroshima Limited successes to date • Taxonomy of anti-spam techniques • Slow progress via wiki • Taxonomy of spamming techniques • Slower progress via wiki • http://wiki.asrg.sp.am

  12. IETF-76 -- Hiroshima Why not more active? • Researchers more aimed at publishing • Very hard problems • e.g., try to compare two spam filters • Useful to describe “folklore” • Much is widely used, poorly documented • Mailing list • Free consulting on anti-spam techniques, avoids many reinvented wheels

  13. Scalable, Adaptive Multicast Research Group

  14. IETF-76 -- Hiroshima Scalable Adaptive Multicast (SAM) RG • Problem Space • ALM that uses native multicast where available • Unified multicast over diverse networks • Group membership management • Chairs • John Buford and Thomas Schmidt • Communities represented in SAM RG • ALM in P2P overlays • XCAST • Native multicast • Streaming in mobile networks • Applications • Interim meetings to foster collaboration with research community Hybrid Overlay/ALM Native Multicast AMT ALM Network

  15. IETF-76 -- Hiroshima Hybrid Multicast Framework & Overlay Protocol Framework • Example hybrid tree using native multicast (N), overlay layer multicast (A), and AMT • draft-irtf-sam-hybrid-overlay-framework-02 Protocol • Example message types for Tree Lifecycle: • Create Tree • Join • Join Via AMT Gateway • JoinWithNativeLink • draft-buford-irtf-sam-overlay-protocol-01

  16. Common Access to Hybrid Multicast Overall objective: pave the way for a universal multicast use by applications and thus facilitate deployment • Approach: Define a common access technology to hybrid multicast at end systems by • A common API MCast programming with namespace support • Middleware that ensures mcast activation and namespace mapping at end systems & gateways • draft-waehlisch-sam-common-api-01 • draft-lim-irtf-sam-alm-api-00.txt

  17. IETF-76 -- Hiroshima Future Work: SAM Simulation Environment • Various structured overlays (Chord, Kademlia, Pastry, …) • “Simple” Topology and more realistic topologies • ALM • P2P-SIP • Needed for SAM: • Coupling of ALM with Native layer OverSIm www.oversim.org INET inet.omnetpp.org • TCP • UDP • IP • ICMP • OSPFv2 • ARP • Ethernet MAC • Network Topology • Needed for SAM: • IGMPv3 • MLDv2 • AMT - underway • PIM - incomplete • XCAST - Done OMNet++ www.omnetpp.org

  18. IETF-76 -- Hiroshima Future Work: Hybrid Multicast Testbed • Sites support overlay multicast in WAN and local native multicast • Purpose: study SAM RG protocols • May integrate with several other testbeds: GENI, G-LAB, … Node Components Hybrid Multicast Testbed Initial Sites
