Final Group description

NOTE: Work in the ITU-T Coordination Program was folded into the Liaison Oversight Program in March 2015.


The ITU-T Coordination Program is an effort focusing on the relationship between the IETF and ITU-T, where some of the highest frequency interaction currently takes place. The objective of this program is to establish and maintain a cooperative and mutually respectful relationship that serves the best interests of both SDOs.

As with other Programs, the ITU-T Coordination Program develops recommendations for consideration by the IAB, and the IAB retains its oversight responsibilities under RFC 2850.

This program is divided into two components. One component (going by the name ITU-T strategic planning) provides strategic coordination planning, while the other (going by the name ITU-T liaison coordination) provides tactical, detailed, and specific liaison coordination.

Both components provide advice to the IAB, and to any other activities in the IETF that need to work with the ITU-T, especially the IESG. Both components provide recommendations to the IAB.

Specifically, the ITU-T Strategic Planning Component:

  • Develops the principles guiding the relationship and implements and maintains them
  • Provides advice to the IAB relating to strategic and directional developments within ITU-T
  • Prepares specific strategic recommendations and documents at the request of the IAB

The ITU-T liaison coordination component:

  • Ensures that the liaison managers are aware of relevant activities in the ITU-T
  • Ensures that the participants speaking on behalf of the IETF are all aware of the messages and goals of our interaction with the ITU-T
  • Monitors and guides the emergence and development of close or possibly overlapping work items in IETF and ITU-T. Examples include: Q.Flowstatesig in ITU-T SG11 Q5, Codec in IETF RAI, Deep Packet Inspection in ITU-T SG13 Q17, MPLS-TP in ITU-T SG15.
  • Tracks technical work within the ITU-T that relates to or has impact on IETF work items and/or responsibilities and reports consistently to the IAB
  • Coordinates the liaison activity at all levels: at the level of a WG, an IETF Area, the IETF, and the IAB
  • Organizes periodic reviews of the liaison relationships with ITU-T

All ITU-T Coordination Program members are appointed by the IAB. Membership is based primarily on expertise and/or perspective, as well as joint participation that members bring to the group. Members serve on personal title. All appointed IETF liaisons to ITU-T are expected to be members of this group, participating in the liaison coordination activities.

ISOC is an important contributor to all aspects of this program and provides participants to both components; both to provide their expertise and to ensure coordination with ISOC activities in this area.
