3.3. ISO TC204 Liaison Report

–Begin TC204 Liaison Report, Alexandre Petrescu–

ISO TC204 is 'ITS' - Intelligent Transport Systems.

My pair Thierry Ernst at ISO is copied to this email.

Please allow me to give a brief summary report of last 3 months.

1. Updated procedures of ISO.  This describes how ISO works.  The email 
attachment is titled "ISO/TC 204 - Release of the 2021 edition of the 
ISO/IEC Directives Parts 1, Part 2 and Consolidated ISO Supplement"; 
Communicated on April 30th, 2021.

   Such a document was useful for some IETF works recently.  I can send 
you the pdf if needed.

   In the LAMPS WG the contributors and Chair needed a way to speak back 
to ISO, at the beginning of this year.  They needed the most recent 
information about how to talk back to ISO about a quirk in an ISO 
documennt about the length of an OCSP field specified differently in an 
I-D.  It is by reading this process document that people who want to 
talk to ISO that they can formulate the liaisons.  Also, the persons of 
IETF John Klensin and Russ Housley are instrumental in realizing the 
liaison, but the process document is a basis.

2. Advertisement of a webinar planned in June 2021, titled "ITU Webinar 
and 6th meeting of ITU-T Focus Group on AI for Autonomous & Assisted 
Driving (FG-AI4AD), fully virtual, 2-3 June 2021".  

   It was organised by ITU (not ISO), but advertised to ISO as well, and 
further to its liaisons.  So it could have been advertised to IETF as 
well.  Communicated on May 17th, 2021.

   During this webinar it is (was) possible to assist and see which part 
of AI technologies might be interesting for IETF.  Generally speaking, 
AI is a heavy-compute function and cars don't carry too big computers; 
as such an offloading of the AI function is always necessary; but off-
loading means to use a communications network in particular way, and 
certainly with IP.  One might try to determine which WG at IETF might 
consider these communications needs of AI in cars.

3. Liaison from ITU-T to ISO titled "Functional architecture of roadside 
multi-sensor data fusion systems for autonomous vehicles", on June 22nd, 
2021.

  This is an official liaison from ITU-TO to ISO, and ISO TC204 in 
particular.  This liaison statement is pertinent to IETF as well, but 
was not sent as a liaison to IETF.  But one could informally inform the 
IPWAVE WG.

  For example, if I assume that a 'roadside multi-sensor data fusion 
systems for autonomous vehicles' is the deployment I saw in a City where 
people put lidars on poles around a round-about (instead of putting 
these lidars in the cars) one immediately sees the necessity of the use 
of a communication system.  A communication system of the size of a 
round-about is probably able to use just a WiFi network, or a DSRC 
network.

  This work item might develop architecture at ITU, but IETF might help 
in developing a related communication system for this architecture.  It 
can be explored.

4. Next ISO/TC204 Plenary is in October.  In this Plenary I will attend 
online.  I will again advertise RFC8691 produced by the IETF IPWAVE WG 
at the request of an earlier liaison from ISO TC204.  I will need help 
to make this advertising more efficient.

5. During the last ISO TC204 Plenary, on April 21st, I gave a 1-slide 
presentation to ISO TC204 about what is happening at IETF IPWAVE WG. 
(pdf attached).  This was advertised internally to all ISO, containing 
all liaison reports from other SDOs into ISO TC204.  There were no 
questions.

6. During the last ISO TC204 Plenary my liaison pair expressed interest 
in a particular technical topic that might be relevant for IPWAVE WG 
(direct communications between cars by using IPv6).  But that is an 
informal expression.  If we want to bring to IETF then we need to make 
it more formal, to identify whether or not there are other organisations 
or persons interested to work on the topic, and more.

This is a summary.

3.4. RFC Editor Liaison Report

–Begin RFC Editor Liaison Report, John Levine–

An ad-hoc committee convened by the RSOC is still working through the 
changes to the XML V3 vocabulary since RFC 7991 and making slow but 
perceptible progress.  We hope to wrap it up this month.

Now that the exec director has awarded the contract to redo bibxml, the 
[Temporary RFC Series Project Manager] is working with him and the RPC 
to ensure that the new version addresses all of the warts in the old 
version that caused extra work for the RPC, e.g., inconsistent treatment 
of author addresses and initials.

–End RFC Editor Liaison Report, John Levine–

4. BOF Coverage for IETF 111

The IAB agreed on the following BOF coverage for IETF 111:

  • APN: Deborah Brungard, Russ White
  • DANISH: Jiankang Yao
    • Note: Wes Hardaker is a co-chair
  • MADINAS: Ben Campbell
  • OHTTP: Wes Hardaker, Tommy Pauly, David Schinazi
  • SINS: Cullen Jennings

5. IAB Statement on Inclusive Language

The IAB approved the text for the IAB Statement on Inclusive Language in IAB Stream Documents. Cindy Morgan will post the statement on the IAB website and send an announcement.

6. Update on Liaison Coordination

Wes Hardaker and Tommy Pauly updated the IAB on the actions they have taken since taking on the Liaison Coordinator role.

So far, the Liaison Coordinators have had 30-minute calls with 20 of the current liaison managers, discussing things like:

  • How much time is spent interacting with the organization?
  • How much prior knowledge of the organization is needed to fill the liaison manager role?
  • Does the liaison manager send updates to the IAB about important topics (and if so, how frequently)?
  • Does the IAB communicate effectively with the liaising organization?
  • Is there anything the IAB can do to help the liaison manager?

The time spent by liaison managers varies greatly; many have quiet periods with spikes of activity. Having liaison managers report to the IAB every 6 months seems like a reasonable middle ground for most liaisons, with some reporting either annually or every 3 months instead, depending on the level of activity.

Most liaisons managers said that an understanding of the other SDO and the technology involved was required in order to be an effective liaisons managers. Specifically, liaison managers need to participate in both the IETF and the other SDO; picking a candidate with experience is critical.

Future action items include:

  • Improving liaison manager role hand-overs
  • Discussing whether liaison managers should listen to IAB calls
  • Coming up with a list of IETF hot topics for liaisons managers
  • Improving reporting between the liaison managers and the IAB
  • Reviewing existing liaison relationships to see if they are still needed
  • Encouraging liaison managers to use the e-mail list
  • Tracking contacts that are no longer active
  • Developing guidance on reporting and “early warnings”
  • Discussing changes to tooling requirements

7. Tech Topics from the IAB Retreat Redux / Technical Discussion Topics after IETF 111

Jari Arkko outlined some steps the IAB can take to better understand the role of interoperable applications:

  • Step 1: understand what’s going on
  • Step 2: understand why this is happening
  • Step 3: do something about it

In order to understand what is going on, Jari Arkko suggested looking at the applications on a user’s phone. Certain categories of applications are mostly interoperable (e.g. PSTN, e-mail, calendars), while others are not. Roughly two-thirds of applications do not interoperate at the app level. The difference largely comes down to business reasons. Different applications have different interoperability needs.

Wes Hardaker noted that businesses need incentives to go to interoperable models.

Mirja Kühlewind asked if anyone was willing to drive future IAB work on this topic. Jari Arkko and Cullen Jennings both said that they would like to be involved in the work, but neither felt in a position to be able to drive it. The IAB will revisit this sometime after IETF 111.

Another potential topic for IAB work is consolidation and discovery. Centralization and consolidation are driven by many factors, including economic and network effects, but also by some aspects of technology. Discovery can be an area where technical work might have an effect.

A possible outline for a document on consolidation and discovery could be:

  • Definition
  • Negative effects of excessive consolidation
  • Which issues are in the domain of economics/technical
  • Examples
  • Recommendation
  • Considerations

Cullen Jennings suggested that Jari Arkko put this outline into a document, and that the IAB spend one of their future technical discussion slots trying to flesh it out more.

8. Executive Session: RZERC Appointment

In an executive session, the IAB re-appointed Tim April to the ICANN Root Zone Evolution Review Committee (RZERC) for an additional one-year term.

9. Next IAB Meeting

The next IAB meeting will be on 2021-07-21 at 1400 UTC.

10. In-person retreat

Lars Eggert noted that he expects a decision by the end of August about whether it will be viable to hold an in-person IAB/IESG retreat in October.
