1.  Introduction

  In 2020, the COVID-19 pandemic forced the IETF to convert all its
  plenary meetings to online-only events.  This document records the
  experience gained by holding plenary meetings fully online and
  proposes guidelines based on this experience.  In general,
  participant surveys indicated satisfaction with the organization of
  these meetings.

  Although these guidelines reflect lessons learned in 2020 and 2021,
  the IETF is encouraged to continue to experiment with the format and
  agenda of fully online meetings, using this document as a baseline.

  Hybrid meetings (meaning meetings that have large remote
  participation but also onsite participation) are out of scope.
  However, some of the experience gained from fully online meetings
  might also provide input for decisions regarding the organization of
  hybrid meetings.

1.1.  Requirements Language

  The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
  "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
  "OPTIONAL" in this document are to be interpreted as described in
  BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all
  capitals, as shown here.

  This document uses the term "plenary meeting" for the whole IETF
  meeting that covers the IETF meeting week; this term is used to
  distinguish the plenary meeting from other IETF meetings like
  "interim meetings".  The term "administrative plenary" is used for
  the respective session during the IETF meeting week that is usually
  hosted on Wednesday.

2.  Some History

  When the World Health Organization (WHO) declared a worldwide
  pandemic in March 2020, the IETF canceled its plenary meeting and
  organized an online replacement in less than 2 weeks.  For this first
  online-only meeting, the agenda was reduced to a set of sessions that
  benefited most from cross-area participation, like BoFs, first-time
  meetings of new working groups, and dispatch sessions.  It also
  included the administrative plenary to preserve the official handover
  procedures that occur at March IETF meetings, as described in
  [RFC8713].

  With a reduced agenda, the meeting format was two sessions (about 4
  hours) per day with a maximum of two parallel tracks.  Other working
  group meetings were scheduled as interims over the following 6 weeks.
  The IESG published a purely advisory recommended schedule
  [INTERIM-SCHEDULE] to reduce conflicts among those interims.

  While satisfaction was high right after the meeting
  [IETF107-FEEDBACK], some participants later indicated in mailing list
  discussions that the period of intensive interims had a greater
  impact on their calendar than a single plenary meeting week, and in
  some meetings participation was reduced.  Those interims tended to
  occur at times convenient for the bulk of participants, which was
  convenient for most but could exclude those in less common time
  zones.

  For the remainder of 2020 and 2021, the online schedule was switched
  back to be similar to an in-person meeting (1- to 2-hour slots and
  eight or nine parallel tracks).  However, each day was limited to 5-6
  hours in recognition that remote participation is more tiring.

  All fully online meetings followed the time zone of the planned in-
  person meeting location.  As a 6-hour agenda has some flexibility
  regarding the start time while still fitting within a previously used
  8-hour in-person agenda, the start time was approximately noon, with
  adjustments of an hour or so to mitigate the impact of early morning
  hours in time zones with many participants.  As selection of in-
  person meeting sites was consistent with the 1-1-1 guideline as
  documented in [RFC8719], this approach was intended to share the
  burden across all common geographies roughly equally.

3.  Guidelines for Online Meeting Planning

3.1.  Time Zone Selection

  The following algorithm was not used in 2020 or 2021, but it enables
  most participants to avoid late-night sessions in two out of every
  three fully online IETF plenary meetings.  Basically, every fully
  online meeting is for two regions of the three regions described in
  [RFC8719], with one being roughly after sunrise and the other around
  sundown.  This has the trade-off that the third region is in the
  middle of night.

  The times are also seasonally adjusted to leverage differentials in
  Daylight Saving Time.  These time slots are as follows, in UTC, based
  on the Daylight Saving Practices at the time of publication:

  +===============+=========================+=========================+
  | Name          | Times (Northern Summer) | Times (Northern         |
  |               |                         | Winter)                 |
  +===============+=========================+=========================+
  | North America | 0500-1100 UTC           | 0600-1200 UTC           |
  | Night         |                         |                         |
  +---------------+-------------------------+-------------------------+
  | Asia Night    | 1300-1900 UTC           | 1400-2000 UTC           |
  +---------------+-------------------------+-------------------------+
  | Europe Night  | 2200-0400 UTC           | 2200-0400 UTC           |
  +---------------+-------------------------+-------------------------+

                                 Table 1

  Note that the "Europe Night" slot covers the "early morning" slot for
  Asia where most countries do not have Daylight Saving Time.

  If Daylight Saving Practices change -- this change is under
  consideration in multiple countries at the time of publication --
  this table may need adjustment.

  The intent of rotating between these three slots is to scatter
  meetings throughout the course of the global day, to maximize the
  ease of participants so that no attendee has to be consistently
  inconvenienced, regardless of their location and what time of day is
  optimal for their schedule.  However, as participation is distributed
  globally, it needs to be acknowledged that restricting the scheme to
  three regions observes the intent of [RFC8719] but does not achieve
  the goal of two non-late-night sessions for all participants equally.

3.1.1.  Guidelines for Selection

  The IETF SHOULD select a start time from these three choices based on
  the prior three meetings.  The following table covers all
  permutations of previous meetings held in person in Region A, B, or C
  or remotely in the nights of one of those regions.

  +====================+==================+==============+===========+
  | Three Meetings Ago | Two Meetings Ago | Last Meeting | Online    |
  |                    |                  |              | Selection |
  +====================+==================+==============+===========+
  | Any                | Any              | In-Person A  | A Night   |
  +--------------------+------------------+--------------+-----------+
  | Any                | Online A Night   | Online B     | C Night   |
  |                    |                  | Night        |           |
  +--------------------+------------------+--------------+-----------+
  | Online A Night     | In-Person B      | Online B     | C Night   |
  |                    |                  | Night        |           |
  +--------------------+------------------+--------------+-----------+
  | In-Person A        | In-Person B      | Online B     | A Night   |
  |                    |                  | Night        |           |
  +--------------------+------------------+--------------+-----------+
  | In-Person A        | In-Person A      | Online A     | See below |
  |                    |                  | Night        |           |
  +--------------------+------------------+--------------+-----------+
  | Online A Night     | Online B Night   | Online C     | A Night   |
  |                    |                  | Night        |           |
  +--------------------+------------------+--------------+-----------+

                                Table 2

  This table follows two basic guidelines:

  1)  Whenever a fully online meeting follows an in-person meeting, the
      online meeting time is used that most disadvantages the
      participants in the time zone where the in-person meeting was
      held.

  2)  If multiple fully online meetings follow each other, the time
      zone selection should be rotated based on the most recent time
      zones in which the in-person meetings were held.

  The final case occurs in the rare event that back-to-back in-person
  plenary meetings occur in the same region.  In this case, find the
  most recent meeting that was in neither 'A' (if in person) nor 'A
  Night' (if fully online).  If this meeting was in person in region
  'B', then the next meeting should be in 'B Night'.  If it was remote
  in 'B Night', the next meeting should be in 'C Night'.

3.2.  Number of Days and Total Hours per Day

  By 2021, fully online meetings were consistently held over 5 days
  with roughly 6-hour meeting days.  The day with the administrative
  plenary, which concludes with multiple open mic sessions, sometimes
  exceeded this limit.

  Six hours of online meetings, with two 30-minute breaks, was a
  compromise between the physical limits of attending an online meeting
  in an inconvenient time zone and the demand for many sessions with a
  manageable number of conflicts.  The IETF 109 feedback
  [IETF109-SURVEY] indicated broad satisfaction with a 5-day meeting
  but only medium satisfaction with the overall length of each day.

  The IETF did not seriously consider extending sessions into the
  weekend before or after the main meeting week, although at IETF 108
  and subsequent meetings the Hackathon occupied the entire week before
  (see [RFC9311]).

3.3.  Session/Break Length

  For fully online meetings, there are typically fewer sessions per day
  than for in-person meetings, to keep the overall meeting day to
  roughly 6 hours.  With fewer sessions, chairs were offered only two
  options for session length (instead of three).

  IETF 108, based on an indicated preference of the community,
  scheduled 50- and 100-minute slots, with 10-minute breaks, in order
  to keep the overall day length at 5 hours.  This resulted in many
  sessions going over time, which indicated that 10 minutes for breaks
  is not practical.

  The survey after IETF 109 [IETF109-SURVEY] showed high satisfaction
  with 60/120-minute session lengths and 30-minute breaks, and a
  significant improvement in satisfaction over IETF 108.

  The longer breaks, while extending the day, provided adequate time
  for meals, exercise, and "hallway" conversations using online tools.

3.4.  Number of Parallel Tracks

  In-person meetings are limited in the number of parallel tracks by
  the number of meeting rooms, but online meetings are not.  However,
  more parallel tracks would increase the number of possible agenda
  conflicts.

  If the total number of requested sessions exceeds the capacity of the
  usual eight parallel tracks, it is possible for a fully online
  meeting to simply use more tracks.  If the number and length of
  meeting days are seen as fixed, this decision is implicitly made by
  the working group chairs requesting a certain number of sessions and
  length.

  IETF 111 used nine parallel tracks for some of the sessions and
  experienced slightly more conflicts in the agenda-scheduling process,
  though there was no statistically significant increase in
  dissatisfaction about conflicts in the survey [IETF111-SURVEY].

  The IESG encouraged working group chairs to limit their session
  requests and use interim meetings aggressively for focused work.

4.  Additional Considerations and Recommendations

4.1.  Full vs. Limited Agenda (and Interim Meetings)

  The IETF 108 meeting survey [IETF108-SURVEY] asked about the
  structure of that meeting (full meeting) compared to that of IETF
  107, which hosted only a limited set of sessions followed by interims
  in the weeks after.  The structure of IETF 108 was preferred by 82%.
  Respondents valued cross-participation and an intensive meeting week
  for maintaining project momentum.

  Furthermore, a well-defined meeting time, rather than spreading many
  interims over the whole year, can make deconflicting with other non-
  IETF meetings easier.

  However, interim meetings can also help to reduce scheduling
  conflicts during an IETF week and allow for a more optimal time slot
  for the key participants.  While interim meetings are less likely to
  attract people with casual interest, they provide a good opportunity
  for the most active participants of a group to have detailed
  technical discussions and solve recorded issues efficiently.

4.2.  Flexibility of Time Usage

  This document recommends further experiments with reducing conflicts
  by leveraging the increased flexibility of the online format.

  An in-person meeting must fit all sessions into an acceptable length
  for international travel (usually roughly a week), but online
  meetings do not have that constraint.

  Therefore, it would be possible to keep most regular working group
  sessions within the usual 5 main meeting days but have some of the
  more conflicted sessions in other dedicated time slots.  As the
  Hackathon for fully online meetings is usually held in the week
  before the online plenary meeting [RFC9311], that week is already a
  highly active week for many IETF participants and might provide an
  opportunity to schedule a few selected sessions.

  This might work especially well for sessions that are of high
  interest to a large part of the community, such as BoFs and dispatch
  meetings, and therefore hard to schedule during the main IETF week.

  At IETF 112, the IESG ran an experiment where the administrative
  plenary was scheduled on the Wednesday before the official session
  week.  The experiment report [IETF112-EXPERIMENT] found that it led
  to a reduction in scheduling conflicts but also a slight drop in
  attendance of the administrative plenary, partly due to insufficient
  awareness.

4.3.  Inclusivity and Socializing

  Participation in the fully online meetings in 2021 was high and had a
  stable per-country distribution, even though time zones were rotated.
  This indicates that online meetings support a more consistent
  geographic distribution of participants than in-person meetings,
  where participation often fluctuates based on the location.

  However, online meetings do not provide an equivalent opportunity to
  socialize.  Despite significant investment in tools to foster hallway
  conversations, many did not use those tools, whether due to ignorance
  of them, dislike of the tools, or a preference for other activities
  at home (including sleep and food) over hallway interactions.

  There was a decrease in submissions of new (-00) Internet-Drafts
  during 2020 and 2021, although the overall number of draft
  submissions remained stable; this decrease in new submissions might
  have resulted from the loss of these interactions.  Informal
  conversations might be important to inspire new work.

4.4.  Experiments

  This document recommends further experiments with the meeting
  structure.  Often, only practical experience can answer open
  questions.  A given meeting SHOULD only experiment with one major
  change at a time in order to be able to assess the outcome correctly.
  Furthermore, the IESG SHOULD announce any such experiment well in
  advance, so people can adjust to changes and potentially provide
  feedback.

4.5.  IANA Considerations

  This document has no IANA actions.

4.6.  Security Considerations

  This document has no security considerations.
