IRTF Chair
IETF-72 – Dublin
IRTF Status
• Four Research Groups (RGs) met this week
– Anti-Spam RG
– Routing RG (Fri)
– Host Identity Payload RG
– Mobility Optimizations RG
• Reviewing the Anti-Spam RG with the IAB
(tomorrow)
IETF-72 -- Dublin, Ireland

IRTF RFCs
• 3 IRTF Stream RFCs published:
– RFC5166: Metrics for the Evaluation of Congestion
Control Mechanisms (TMRG)
– RFC5184: Unified Layer 2 (L2) Abstractions for Layer
3 (L3)-Driven Fast Handover (MOBOPTS RG)
– RFC5207: NAT and Firewall Traversal Issues of Host
Identity Protocol (HIP) Communication (HIPRG)
• 3 IRTF drafts in RFC Editor queue
• 2 drafts in progress towards publication
• Draft to formally establish an IRTF RFC
document stream should be out in coming weeks
– Publication is entwined with draft-iab-streams-headersboilerplates and revision to RFC3932
– Discussion of these documents to take place on rfcinterest mail list
IETF-72 -- Dublin, Ireland

Suggestions for New Work
• Continued interest in an RGs on
– unwanted traffic mitigations
– network virtualization

A few RG highlights...
Anti-Spam RG
• draft-irtf-asrg-dnsbl
– Draft on mechanisms used for blacklists
– To be standards track
• draft-irtf-asrg-bcp-blacklists
– Recommendations on blacklist operations
• Populating wiki on spam mitigation techniques
– May evolve to document analyzing the worst (WCP)

Routing Research Group
• Focus has moved from advocating proposals
to discussing tradeoffs of different
architectural approaches
– Lots of discussion (1250 msgs since IETF-71)
