1. IETF 69 Technical Plenary

2. Agenda Welcome IRTF Chair’s report –Aaron Falk IAB Chair’s report –Olaf Kolkman Open microphone session

3. Update on the Internet Research Task Force Aaron Falk IRTF Chair IETF-69 -- Chicago, Illinois

4. IRTF 14 Research Groups working on topics related to Internet protocols, applications, architecture and technology Some groups very tied to IETF work, others not so much Most groups are open, all maintain open mailing lists Not too structured: –Room for overlaps in scope, very hard problems, diverse management styles –But also pre-standardization maturation

5. IRTF Status Seven Research Groups met at this IETF –SAMRG, DTNRG, EME/HIPRG, MOBOPTS, ICCRG, RRG Published draft-irtf-rfcs-01 on the IRTF RFC review and publication process 1 IRTF RFC published since IETF-68 –RFC4838 Delay-Tolerant Networking Architecture –~10 drafts in-progress towards publication

6. Routing Research Group Meeting tomorrow. Very active list (and on ram list) Still producing new and modified proposals. Converging on design goals.

7. Delay Tolerant Networking RG RFC 4838 (architecture document) published –17 drafts in the tracker, 4 nearing RFC readiness Held an interim meeting in Dublin. –Much of the discussion was security-related. Met Tue morning this week: –Discussion focused on reliability and neighbor discovery. Next planned meeting: IETF-71.

8. Mobility Optimizations RG Met this week Document on Layer 2 abstrations for mobility has completed IRSG review Working on: –Location Privacy and Mobility, –Multicast Mobility

9. End-Middles-End RG Held a joint meeting with HIP RG at IETF-69 –EME complements HIP RG work for providing name space and mechanism to relay policy requests –EME can help HIP with NAT traversal –Potential future collaboration with HIP: larger scale experiment Continuing to discuss Paul Francis’ NUTSS proposal

10. Host Identity Protocol RG Joint meeting with EMERG held on Tuesday: –to explore possible architectural synergy Three new drafts presented this meeting: –Two related to HIP as part of the P2PSIP architecture –One regarding the applicability of shim6 REAP protocol to HIP

11. Internet Congestion Control RG Two current drafts: –Survey of current congestion control RFCs Intention: provide CC designers with guide to related work –Survey of open CC research issues Charter item Starting to evaluate congestion control proposals for TSV area Met yesterday at IETF-69 Planning to meet in Manchester in conjunction with PFLDnet 2008

12. Scalable, Adaptive Multicast RG Two active IDs: –SAM Framework, –Application-Layer Multicast (ALM) Router on PlanetLab ALM survey published as book chapter Met this week Next meeting: planned for IETF 71 (Philadelphia)

13. Crypto-Forum Research Group Published a new message authentication code "VMAC: Message Authentication Code using Universal Hashing" List discussion on a variety of technical issues (AES-based KDFs, AEAD, SIV draft)

14. Internet Measurement RG Workshop on Application Classification and Identification (WACI) to be held October 3rd at BBN Technologies in Cambridge, MA.

15. Anti-Spam Research Group Working on DNS Black Lists: –Progress (slow) toward publishing the DNSBL definitions draft –DNSBL Guidelines draft may follow Seeking interest in taxonomy of anti-spam strategies Occasional snake-oil salesmen show up and get little sympathy

16. Network Management RG Pretty quiet since Prague IETF Some work on management trace analysis Contemplating/planning workshops and future meetings

17. Transport Modeling RG “Evaluation Metrics for Congestion Control” now in IRSG review A new document on "An NS2 TCP Evaluation Tool Suite” along with a web page with simulation scripts under discussion.

18. Peer-to-Peer Research Group Currently soliciting proposals for new work –Expected to feed into a charter update In need of new chairs
