2. ITU-T Liaison Update 

  Scott Mansfield, the IETF Liaison Manager to ITU-T, joined the IAB to 
  give an update on recent activities.

  There have been more than 25 liaison statements between the IETF and 
  the ITU-T over the past year, which are available in the Datatracker 

  ITU-T SG13 is currently working on:

    • JCA-IMT2020 (5G and Beyond)
    • JCA-IdM (Identity Management)
    • FG-AN (Focus Group on Autonomous Networks) (Status)
    • Correspondance Group on ML Datasets
      - A standardization approach for datasets applicable for AI/ML in 
        networks (including allied aspects such as data models, 
        metadata and impact on the networks of AI/ML techniques in 
        relation with this study) 
    • AI standard roadmap (Y.sup.aisr)

  ITU-T has started a Focus Group on Metaverse. The group will analyze 
  the technical requirements of the metaverse to identify fundamental 
  enabling technologies in areas from multimedia and network 
  optimization to digital currencies, Internet of Things, digital 
  twins, and environmental sustainability. See:

  ITU-T has a Focus Group on Autonomous Networks (FG-AN). See: The 
  FG's deliverables include use cases for Autonomous Netwo​rks​, an 
  architecture framework for Autonomous Networks, and a trustworthiness 
  evaluation for autonomous networks including IMT-2020 and beyond.

  ITU-T has a number of Joint Collaboration Agreements that may be of 

    • IJCA-IMT2020 (IMT2020 and Beyond)
    • IJCA-IoT and SC&C (Internet of Things and Smart Cities and 
    • IJCA-IdM (Identity Management)
    • Joint Coordination Activity on Machine Learning (JCA-ML)

  The ITU's World Radiocommunication Conference (WRC) will be held from 
  2023-11-20 to 2023-12-15.

  The next ITU World Telecommunication Standardization Assembly (WTSA) 
  will be held in Q4 of 2024. Preparation is currently underway; it is 
  expected to discuss the potential consolidation of Study Groups and 
  the expansion of the ITU's mandate.

  Upcoming ITU meetings of interest include:

    • SG15 (Networks, technologies and infrastructures for transport, 
      access and home​)
      - April 2023
    • TSAG
      - May 2023
    • SG13 (Future Networks)

  Wes Hardaker thanked Scott Mansfield for the update, and asked how 
  the IAB can help. Scott replied that it would be wonderful to have 
  more people looking at all of the things coming in.

3. Evolvability, Deployability, & Maintainability (EDM) Program Review 

  Tommy Pauly reported that the Evolvability, Deployability, & 
  Maintainability (EDM) Program met during IETF 116; it was their 
  second in-person meeting. The Program has also had seven virtual 
  meetings since forming in late 2020.

  The EDM Program has worked on a few documents:

    • draft-iab-use-it-or-lose-it, Long-Term Viability of Protocol 
      Extension Mechanisms (Published as RFC 9170 in December 2021)
    • draft-iab-protocol-maintenance, Maintaining Robust Protocols 
      (Currently in the RFC Editor Queue)
    • draft-eckel-edm-find-code, Find Code Related to an Internet-Draft 
      or RFC

  David Schinazi said that the EDM Program takes a two-pronged 
  approach. The first is to publish RFCs about best common practices 
  from what we've seen and learned; the second is to help facilitate 
  the use of the protocols during and after the publication process. 

  Mirja Kühlewind said that making recommendations on protocol design 
  is something the IAB does, and the EDM Program is one way to do that.

  David Schinazi said that having the Program has been very helpful in 
  allowing the community to give the IAB really good advice on how to 
  phrase things.

  Mirja Kühlewind asked if the current Program description still makes 
  sense. Tommy Pauly replied that it does for now; if things change, it 
  may make more sense to spin up a new Program rather than try to re-

  Mirja Kühlewind noted that the EDM Program Meeting appeared on the 
  IETF 116 agenda, and asked whether that was helpful. Tommy Pauly 
  replied that he thinks it was, as they were able to get input from 
  people who don't generally show up to the interim meetings. 

  Mirja Kühlewind suggested that the IAB add a topic on future IAB 
  Technical Programs to the 2023 retreat agenda.

4. A Vision for the Internet 

  The IAB discussed the "Vision for the Internet" document. Mallory 
  Knodel asked whether the document should be trying to predict the 
  future, provide direction for the future, provide a current snapshot 
  in time, or reflect back on what the Internet has been thus far.

  Mirja Kühlewind said that the document should explain how the 
  Internet works and evolves over time, and that it is important that 
  it keeps evolving.

  Lars Eggert suggested that they work on the abstract for the document 
  before committing to a title.

  Wes Hardaker said that the key point is that the Internet keeps 
  evolving with the standards process.
