IAB Retreat

The Internet Architecture Board (IAB) held its 2012 retreat 10–11 May in Washington, DC, U.S.A.1 During the retreat, IAB members reviewed the Programme and Initiative model,2 which was developed last year. They concluded that the Programmes proved useful in enabling the IAB to achieve both administrative and technical objectives over a multiyear period, while the benefits of the Initiatives (work bundles of both shorter duration and lower priority) were less clear. As a result, the IP Evolution and Emergency Services Initiatives were promoted to Programmes, a new IAB Processes and Tools Programme was created, and the HTTP/Web Evolution, IPv6 for IAB Business, and DNS Initiatives were closed.

The IAB now has Programmes in the following areas:


  • RFC Editor (RSOC)
  • IANA Evolution
  • ITU-T Coordination
  • Liaison Oversight
  • IAB Tools and Processes


  • Privacy
  • IP Evolution
  • Internationalization
  • Emergency Services

IETF 84 Technical Plenary

The IETF 84 Technical Plenary,3 organized by Jon Peterson, focused on Software Defined Networking (SDN). Nick Feamster presented “The Past, Present, and Future of Software-Defined Networking;” David Ward’s presentation, “Programmatic Internet” described some of the issues with the current SDN architecture, and what SDN might mean for the IETF; Ted Hardie presented “Units of Evolution,” a description of how SDN changes the way network elements evolve.

IAB/IRTF Workshop on Congestion Control

The IAB and IRTF held a workshop entitled, “Congestion Control for Interactive Realtime Communication,” on 28 July, 2012, in Vancouver, Canada. Papers and materials for the workshop are posted; minutes are under development.4

RFC Series

The IAB published “RFC Editor Model (Version 2)” (RFC 6635)5 and “Independent Submission Editor Model” (RFC 6548)6 as Informational RFCs within the IAB stream. Collectively, these documents obsolete RFC 5620.7

IANA Evolution Programme

The IETF and ICANN have executed a supplemental agreement, which describes the service levels expected for 2012.8 In May, the IAB submitted an updated ICANN performance evaluation.9 On 2 July, the U.S. National Telecommunications and Infrastructure Administration (NTIA) awarded the IANA Functions contract to ICANN.10

Privacy Programme

The Privacy Programme posted an IPv6 privacy survey.11

Other Document Actions

The IAB adopted “Technical Considerations for Internet Service Blocking”12 as an IAB work item. It approved publication of “Design Considerations for Protocol Extensions”13 and “IETF and ITU-T Standardization Sector Collaboration Guidelines”14 as Informational RFCs within the IAB stream; and issued a Call for Comment on “Architectural Considerations on Application Features in the DNS”15 which was completed on 16 August, and on “Principles for Unicode Code Point Inclusion in Labels in the DNS,”16 which will be complete on 30 September.17

Affirmation of the Modern Global Standards Paradigm

At IETF 84, Russ Housley announced that the IETF, IEEE Standards Association, and W3C were working together to develop an “Affirmation of the Modern Paradigm for Standards.” After an initial round of feedback and edits, IETF Last Call was announced on 10 August and it was complete on 24 August, at which point Russ announced the conclusion of the Last Call.18 More information can be found at, which went live on 29 August.19 The IAB also agreed to adopt the Affirmation as an IAB document.20

Liaison Relations

The IAB has responded to a liaison from the Open Network Foundation (ONF).21

The IESG, IAB, and the IEEE 802 Executive Committee met in Milpitas, California, on 25 July, 2012.22Minutes of the meeting are under development. Next steps arising from the meeting include revising RFC 4441.23

The IAB approved “IETF and ITU-T Standardization Sector Collaboration Guidelines” as an Informational RFC within the IAB stream, and ITU-T TSAG sent their approval in a liaison message.24 In addition, the IAB and IESG posted a liaison to ITU-T TSAG on “Observations on Contribution 74 to TSAG Concerning Modification of IETF Protocols Technologies by the ITU-T.”25


The IAB has reappointed Eric Burger to the ISOC Board of Trustees,26 and Ole Jacobsen to the ICANN Nomcom.27
