IETF 69Technical Plenary

Agenda

• Welcome

• IRTF Chair’s report– Aaron Falk

• IAB Chair’s report– Olaf Kolkman

• Open microphone session

Update on the Internet Research Task Force

Aaron Falk

IRTF Chair

IETF-69 -- Chicago, Illinois

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

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

Routing Research Group

• Meeting tomorrow.• Very active list (and on ram list)• Still producing new and modified proposals.• Converging on design goals.

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.

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

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

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

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

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)

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)

Internet Measurement RG

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

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

Network Management RG

• Pretty quiet since Prague IETF • Some work on management trace analysis • Contemplating/planning workshops and future

meetings

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.

Peer-to-Peer Research Group

• Currently soliciting proposals for new work– Expected to feed into a charter update

• In need of new chairs

Editor

Administration

• Appointed Ted Hardie as member of the ISOC Board of Trustees

• Liaison appointments– Loa Anderson: IAB liaison to the IESG– Danny Mc Pherson: IAB liaison to the

NomCom– ITU-MPLS: Stewart Bryant– ITU-NGN: Scott Brim is stepping down

Inter-Organizational

• ITU was looking for input on their role in Internet policy and standards development.– Provided input with respect to the IETF’s role in

this space– http://www.iab.org/documents/correspondence/2007-05-21-itu-resolution-102.html

• Informal gathering between IETF and ITU leadership on July 21st.– Goal: Get to know each other so that future

interaction collaboration is more effective and fruitful

Inter-Organizational(continued)

• IDN follow up– Proposals in ISO/TC46 that would impact

IDNS• Notified ISO/TC46 of the possible impact on

our work

• DNSSEC updates– RIPE NCC ready to sign e164.arpa– http://www.iab.org/documents/correspondence/2007-07-05-ripe-ncc-dnssec-e164.html

– http://www.iab.org/documents/correspondence/2007-07-24-iab-itu-dnssec-e164.html

Appeals

• None

RetreatOngoing business and possible future work

• Routing and Addressing– Actively following developments and building

common understanding of architectural issues

• IP fundamentals– What assumptions are made in stacks, how do

they relate to original design goals– IP and NAT and architectural questions

• Bridging Gaps– IETF & ISOC, IETF & IRTF, IETF & Other

organizations, IETF and other stakeholders

And now…
