Considerations for Having a Successful "Bar BOF" Side Meeting

「Bar BOF」サイドミーティングを成功させるための考慮事項



New work is typically brought to the IETF by a group of interested individuals. IETF meetings are a convenient place for such groups to hold informal get-togethers to discuss and develop their ideas. Such side meetings, which are not reflected in the IETF meeting agenda and have no official status, are often half-jokingly referred to as "bar BOF" sessions to acknowledge that some of them may eventually lead to a proposal for an official IETF BOF ("birds of a feather" session) on a given topic.

新しい作品は通常、関心のある個人のグループによってIETFに持ち込まれます。 IETFミーティングは、そのようなグループが非公式の集まりを開いて自分たちのアイデアについて話し合い、発展させるのに便利な場所です。 IETFの会議の議題には反映されておらず、公式のステータスもないこのようなサイドミーティングは、冗談で「bar BOF」セッションと呼ばれることが多く、そのうちの一部は最終的に公式のIETF BOFの提案につながる可能性があることを認めています( 「鳥の羽」セッション)を特定のトピックで行います。

During recent IETF meetings, many such "bar BOF" get-togethers have been organized and moderated in ways that made them increasingly indistinguishable from official IETF BOFs or sometimes even IETF working group meetings.

最近のIETF会議中に、このような「bar BOF」の集まりが組織され、公式のIETF BOFまたは時にはIETFワーキンググループの会議と区別がつかなくなるような方法で管理されました。

This document argues that this recent trend is not helpful in reaching the ultimate goal of many of these get-togethers, i.e., to efficiently discuss and develop ideas for new IETF work. It encourages the organizers to consider the benefits of holding them in much less formal settings and to also consider alternative means to develop their ideas. This document also recommends that the community abandon the term "bar BOF" and instead use other terms such as "side meeting", in order to stress the unofficial nature of these get-togethers.

このドキュメントは、この最近の傾向は、これらの集まりの多くの最終目標を達成するのに、つまり新しいIETF作業のアイデアを効率的に議論して開発するのに役立たないと主張しています。それは主催者に彼らをはるかに形式的な設定でそれらを保持することの利点を検討し、また彼らのアイデアを発展させるための代替手段を検討することを奨励します。このドキュメントでは、コミュニティが非公式の集まりの性質を強調するために、コミュニティが「bar BOF」という用語を放棄し、代わりに「サイドミーティング」などの他の用語を使用することを推奨しています。

1. Introduction
1. はじめに

A typical IETF meeting is full of sessions of different kinds. In addition to official IETF and IRTF sessions listed in the meeting agenda (such as working and research group meetings, area meetings, or plenaries), many other unofficial meetings take place. These include meetings between IETF participants from one organization or company, design team meetings, Internet-Draft editing sessions, interoperability testing, directorate lunches, and many others.


Some of these unofficial get-togethers are organized by individual participants with a common interest in initiating new IETF work of some kind. New IETF work often fits into an existing working group and does not require an official "birds of a feather" (BOF) session [RFC5434] to determine community consensus. Nevertheless, the phrase "bar BOF" has commonly been used in the community when talking about such informal get-togethers that are held to discuss potential new work. [RFC4677] (which has been obsoleted by [RFC6722]) characterizes a "bar BOF" as

これらの非公式の集まりのいくつかは、何らかの新しいIETF作業を開始することに共通の関心を持つ個々の参加者によって組織されています。新しいIETFの作業は多くの場合既存のワーキンググループに適合し、コミュニティの合意を決定するための公式の「羽の鳥」(BOF)セッション[RFC5434]を必要としません。それにもかかわらず、「bar BOF」という語句は、潜在的な新しい作業について話し合うために開催されるそのような非公式の集まりについて話すときに、コミュニティで一般的に使用されています。 [RFC4677]([RFC6722]によって廃止されました)は、「バーBOF」を次のように特徴付けます

an unofficial get-together, usually in the late evening, during which a lot of work gets done over drinks. Bar BOFs spring up in many different places around an IETF meeting, such as restaurants, coffee shops, and (if we are so lucky) pools.


During recent IETF meetings, "bar BOFs" have become increasingly indistinguishable from official IETF BOFs or sometimes even IETF working group meetings. The symptoms of this trend are unofficial "bar BOFs" that are held in regular IETF meeting rooms with classroom-style seating, agendas with lengthy slide presentations, use of microphone lines, and even formal consensus calls. And, perhaps most importantly, such meetings have a distinct lack of drinks.

最近のIETF会議中に、「棒BOF」は、公式のIETF BOFや、場合によってはIETFワーキンググループの会議と区別がつかなくなってきました。この傾向の兆候は、教室形式の座席のある通常のIETF会議室で開催される非公式の「バーBOF」、長いスライドプレゼンテーションの議題、マイクラインの使用、さらには正式なコンセンサスコールです。そして、おそらく最も重要なこととして、そのような会議では明らかに飲み物が不足しています。

This document argues that this trend is not helpful in reaching the ultimate goal of many of these get-togethers, i.e., to brainstorm about a technical topic that may eventually lead to new IETF work. It encourages the organizers of these unofficial get-togethers to consider the benefits of holding them in much less formal settings.


This document also recommends that the community abandon the term "bar BOF". The distinction between a BOF, i.e., an official IETF activity, and a "bar BOF", i.e., an unofficial get-together, is lost on many IETF participants, especially newcomers. The similarity in terms has even caused confusion to the point where some participants believe that a "bar BOF" is a required step in the IETF process in order to apply for an official BOF, which is obviously false. For these reasons, the remainder of this document will use the term "side meeting" instead and recommends that the community do the same, in order to stress the unofficial nature of these get-togethers.

このドキュメントでは、コミュニティが「BAR BOF」という用語を放棄することも推奨しています。多くのIETF参加者、特に新規参入者は、BOF(IETFの公式活動)と「BAR BOF」(非公式の集まり)の区別が失われています。用語の類似性により、正式なBOFを申請するために「バーBOF」がIETFプロセスで必要なステップであると一部の参加者が信じているという点まで混乱を引き起こしていますが、これは明らかに誤りです。これらの理由により、このドキュメントの残りの部分では、代わりに「サイドミーティング」という用語を使用し、コミュニティがこれらの集まりの非公式な性質を強調するために同じようにすることを推奨します。

Before going into more detailed advice on how to hold side meetings, it is important to remember that many participants are extremely busy during an IETF meeting. Although having a side meeting to discuss an idea in an informal face-to-face setting is attractive, the scheduling of such meetings is very difficult and needs to happen weeks, if not months, prior to the meeting itself. Conference calls, email discussions, wikis, jabber group chats, and other ways for interacting are also effective at developing ideas and easier to schedule.


2. How to Invite
2. 招待する方法

A good rule of thumb is that a side meeting to discuss and develop a proposal for new IETF work should include the necessary participants to achieve that purpose and no more. Smaller meetings are usually more successful than larger meetings.


Hence, it is often useful to limit attendance carefully. Publicly broadcasting an announcement for a side meeting on a particular topic, e.g., on an IETF mailing list, is therefore not usually a good method of inviting the desired set of participants.


One reason is that if the announcement happens to attract a large response, the logistics of organizing a side meeting for a larger group quickly becomes very difficult. Small groups fit comfortably around a table at a bar or a restaurant or can find a quiet corner in an IETF hallway for a discussion. Larger groups require dedicated meeting facilities, which are limited during IETF meetings, and they generally require much more careful planning in order to get work done.


When publicly announcing a side meeting, it is often not even possible for the organizers to determine how large the resulting get-together will be, forcing them to over-provision for the "best case" of a substantial attendance, even in cases where this turns out to be not necessary. And even when a large group comes together, it often mostly consists of "tourists". Tourists usually do not actively participate in the get-together at all, or they participate with an intent to learn about a topic, which can derail a planned discussion of specific issues and turn it into a tutorial. The attendance of tourists requires finding a larger room and makes the interactions between the active participants more cumbersome, e.g., because microphones need to be used in larger rooms. There are times to expose new ideas to a broader community, but think carefully before publicly announcing a side meeting.


So while publicly announcing a side meeting can be useful in order to gather interested people for a discussion, it often makes sense to still limit attendance. For example, an announcement could say, "We have a table reserved at restaurant X for Y people. If you are interested in attending, please briefly explain how you will contribute to the discussion we are planning to have". If more than Y people respond, the organizers make a selection.

したがって、サイドミーティングを公に発表することは、関心のある人々を議論に集めるのに役立ちますが、出席を制限することはしばしば意味があります。たとえば、「レストランXにはY名様用にテーブルが予約されています。参加に興味がある場合は、予定しているディスカッションにどのように貢献するか簡単に説明してください」のようなアナウンスがあります。 Y人以上が回答した場合、主催者が選択します。

Selecting or specifically inviting IESG or IAB members is not necessary and may not even be advisable in many cases. Some ideas need time to form before they result in anything cohesive, and a side meeting is a good time to develop new ideas. It is usually most useful to approach Area Directors (ADs) and IAB members for comments after an idea has solidified enough so that an elevator pitch can be given. Also, it should be clear that if an AD or IAB member attends a side meeting, it is not necessarily a show of support. They may simply be interested or often may be concerned or troubled with some aspect of the potential work and relation to existing work. On the other hand, when an AD or IAB member declines to attend a side meeting, that is usually not a sign of disinterest or disapproval -- these people have busy schedules, especially during an IETF week.


In the initial stages of developing a proposal for new IETF work, the ability for interested and experienced participants to brainstorm is tremendously important. Brainstorming is facilitated by direct, interactive, and high-bandwidth discussions. This is clearly much more easily achieved in a smaller setting, where half-baked ideas can be dissected and developed. This is often not possible in a larger group. Even worse, a badly run large meeting can sometimes "poison the waters" for a proposed idea by convincing the broader community that the proposal is confused, not ready, or otherwise uninteresting.


Another reason to discuss new work proposals in smaller groups is scope creep, i.e., the tendency of an initially rather tightly scoped area of new work to expand, because people will argue that whatever the initial topic was, it should be expanded to include their particular item of interest. This is harder to control in larger groups. Keeping the scope of new work items narrow is important, because eventual chartering decisions are often much more difficult for larger items of new work than for smaller ones.


It is important to understand that in the IETF, proposals for new work are judged based on their technical merits and on whether there is enough energy and interest in the community to complete the work in a timely manner. This happens in the relevant working group, if one exists, or else during an official BOF session. How many warm bodies fill a room during an unofficial side meeting has no influence on this decision and is not a good metric for reporting interest in a topic to the community or to employers. Discussions about new work are often controversial, and people will show up just to watch the fireworks, learn about a new topic, or make sure the new work does not interfere with work they are already pursuing, without being interested contributing in some way to the actual proposal itself.


Some side meetings are organized to discuss a topic that is also being discussed in an existing working group, either before or after the working group itself meets. Some working groups call these side meetings "ad hoc sessions". The fact that a side meeting is organized by a chair or key participant of a working group in order to discuss topics related to the working group does not make it any more official than other side meetings. An "ad hoc session" is not an official working group session, and no decisions relevant to a working group can be made. Working group consensus can only be established during official sessions or on the mailing list [RFC2418].

一部のサイドミーティングは、ワーキンググループ自体が会合する前または後に、既存のワーキンググループでも議論されているトピックについて議論するために組織されます。一部のワーキンググループは、これらのサイドミーティングを「アドホックセッション」と呼んでいます。ワーキンググループに関連するトピックを議論するために、サイドミーティングがワーキンググループの議長または主要な参加者によって組織されるという事実は、他のサイドミーティングよりも公式になりません。 「アドホックセッション」は公式のワーキンググループセッションではなく、ワーキンググループに関連する決定を行うことはできません。ワーキンググループの合意は、公式セッション中またはメーリングリスト[RFC2418]でのみ確立できます。

3. Where to Meet
3. 会うところ

As the colloquial name "bar BOF" implied, such side meetings are traditionally held in bars or restaurants. Recently, there has been a distinct shift towards holding such get-togethers in regular IETF meeting rooms. One reason for this trend has been discussed in Section 2, namely, that an uncontrolled broadcast announcement requires over-provisioning of facilities.

通称「bar BOF」が暗示するように、このようなサイドミーティングは伝統的にバーやレストランで行われます。最近、そのような集まりを通常のIETF会議室で開催することに明確なシフトがありました。この傾向の理由の1つはセクション2で説明されています。つまり、制御されていないブロードキャストのアナウンスには設備の過剰プロビジョニングが必要です。

A second reason for this trend is that some participants, e.g., non-native English speakers or participants with hearing difficulties, find it difficult to interact or follow a discussion in noisy environments, such as restaurants and especially bars. The organizers of side meetings are encouraged to take this factor into consideration when finding a meeting place. Quiet restaurants are not hard to find, and many offer private dining rooms at no extra charge for larger parties.


A likely third reason why side meetings are increasingly held in IETF rooms is that the booking of such a room currently requires approval by an Area Director. The reason for this practice is simply to make sure that IETF-paid rooms are used for meetings that are in the widest sense IETF-related. However, the approval of a room request for a side meeting has been known to sometimes be reported as Area Director "support" for the topic of the meeting to the community or to employers. No such support is expressed or implied when Area Directors approve room requests! Many routinely say "yes" to every incoming request as long as there are meeting rooms available (and there are typically lots of meeting rooms available outside of normal working group meeting slots).


Holding side meetings in IETF meeting rooms does not make them any more official or valid than get-togethers that happen in other places. Participants have recently begun to list the times and locations of some side meetings on a wiki page, but that does not make them part of the official IETF agenda or otherwise change their unofficial status.


IETF meeting rooms clearly do not provide the most supportive environment for side meetings that require brainstorming on a new technical proposal. One reason is that the classroom-style seating often present in IETF meeting rooms tends to spread people out in rows, all facing towards a front presenter, which is good for presentations but bad for discussion. Because IETF meeting rooms tend to be large and people have a natural tendency to spread out, holding a meeting in one often requires microphone use, which is cumbersome, slows a discussion down, and leads to "question-answer" dialogs between two people, which is much less effective than a group discussion around a restaurant table.

IETFの会議室は、新しい技術的な提案についてブレーンストーミングを必要とするサイドミーティングに最も支援的な環境を提供していないことは明らかです。理由の1つは、IETFの会議室にしばしば存在する教室形式の座席は、列に並んで人々を分散させ、すべてがフロントプレゼンターの方を向く傾向があるためです。これは、プレゼンテーションには適していますが、ディスカッションには適していません。 IETFの会議室は大きくなる傾向があり、人々は自然に広がる傾向があるため、会議を1人で開催するにはマイクを使用する必要があり、マイクの使用が面倒で、議論が遅くなり、2人の間の「質問と回答」ダイアログが表示されます。これは、レストランのテーブルを巡るグループディスカッションよりもはるかに効果的ではありません。

Another reason is more pragmatic. Because the organizers of unofficial get-togethers can only use IETF meeting rooms during times when they are not otherwise in use, such side meetings often happen during breakfast, lunch, dinner, or later in the evening. This prolongs the time during which IETF participants are stuck in the same rooms they're stuck in for the rest of the day, and it prevents them from having a regular and at least somewhat relaxed meal.


Anecdotal evidence exists that at least one Area Director has not been able to set foot outside the IETF hotel for a stretch of several days during IETF 77. (IETF 77 was held in Anaheim, CA, and the food options in and near the hotel were, let's say, of severely limited quality.) It is unlikely that participants in the consequential mental and bodily state will make productive contributions to a side meeting or, in the case of Area Directors, will be extremely receptive towards new work proposals.

少なくとも1人のエリアディレクターがIETF 77中に数日間にわたってIETFホテルの外に足を踏み入れることができなかったという事例証拠が存在します(IETF 77はカリフォルニア州アナハイムで開催され、ホテル内および近くの食事オプションはたとえば、品質が大幅に制限されているとします。)結果として生じる精神的および身体的状態の参加者がサイドミーティングに生産的に貢献したり、エリアディレクターの場合は、新しい仕事の提案を非常に受け入れたりすることはほとんどありません。

Food, drink, and a relaxed atmosphere in which to have a discussion are an essential part of a successful side meeting, because they often need to happen during meal times. IETF meeting rooms offer neither.

食べ物、飲み物、リラックスした雰囲気の中で話し合いをすることは、サイドミーティングを成功させるために欠かせない要素です。 IETF会議室はどちらも提供していません。

4. How to Meet
4. 会う方法

Several of the recent side meetings that were held in IETF meeting rooms emulated official IETF meetings to a degree that made them indistinguishable from a regular working group meeting for the average IETF attendee. This included detailed agendas, lengthy presentations, organizers who refer to themselves as "bar BOF chairs", emulating blue sheets (see Section 4.5 of [RFC4677]), and even hums and other consensus calls (see Section 5.2 of [RFC4677]).


It is not clear as to why this has been happening. One attempt at an explanation may be that holding a get-together in an IETF room and having the organizers behave like chairs behave during regular IETF sessions is causing a Pavlovian stimulus in the attendees. Another explanation attempt is that an IETF meeting room simply does not allow many other forms of discussion. Finally, some organizers may find the process to apply for an official BOF too complex or troublesome (and probably rightfully so) and so decide to simply mimic one, or they had applied for an official BOF, got turned down, and then decided to hold the same meeting as a side meeting.


Whatever the reason for this development, it is reasonably obvious that running a side meeting with a focus on making quick progress on a technical proposal in a way that emulates running a working group session is not very productive. Working group sessions follow certain procedures due to larger audiences, the need to establish formal consensus, etc., that a side meeting can do without.


Having side meetings mimic working group meetings is also confusing to attendees. In at least one case, some side meeting participants believed that they were attending an actual working group meeting, and incorrect press announcements were generated. When side meetings take place at restaurants or elsewhere away from IETF meeting rooms, the chance for confusion is much lower.


Because the reasons for organizing such a get-together are diverse, this section is not making more specific suggestions, other than to note that meeting outside of an IETF meeting room is likely going to shift the dynamics sufficiently so that better interactions and results become possible.

このような集まりを組織する理由はさまざまであるため、このセクションでは、IETF会議室の外で会議を行うとダイナミクスが十分に変化し、より良い相互作用と結果が可能になることに注意する以外、具体的な提案は行いません。 。

5. When to Meet
5. いつ会うべきか

Side meetings are often scheduled following IETF evening plenaries, which sometimes end before the time indicated on the meeting agenda but have in the past also ended much later. It is therefore useful to avoid scheduling side meetings that follow IETF plenaries at a fixed time. Instead, it is recommended to schedule them relative to the end of the plenary, i.e., "X minutes after the end of the plenary". That way, attendees do not need to wait around if a plenary finishes early and do not need to leave a plenary should it run late.


Section 3 of [RFC5434] raises the issue that it is essential to understand all angles of a given problem for which IETF work is proposed. This means that input from the community that can be found at IETF meetings is not all that should be considered. It can be argued that input from other communities -- operator, research, regulatory, etc. -- is at least as important. Hence, organizers should consider the value of holding side meetings at venues where such input can be more easily gathered, such as operator fora (RIPE, NANOG, etc.), research conferences, or other events.


6. Conclusions
6. 結論

Side meeting organizers are encouraged to rekindle the original spirit behind them and organize them outside IETF meeting rooms, at venues with food and drink, for smaller groups, and in a way that does not needlessly mimic the way official IETF sessions are conducted.


It can often be useful to discuss proposals for new IETF work face-to-face in an informal setting, but conference calls, email discussions, wikis, and other means for interactions are also effective at developing ideas, especially given the scheduling difficulties when busy individuals are involved during an IETF meeting.

新しいIETF作業の提案を非公式な状況で直接話し合うことはしばしば有用ですが、電話会議、電子メールによるディスカッション、Wiki、およびその他のやり取りのための手段も、特に忙しいときにスケジュールの難しさを考えると、アイデアの開発に効果的です。 IETFミーティングには個人が参加します。

Finally, it is important to remember that all side meetings during an IETF week are purely informal and have no official status whatsoever.


7. Security Considerations
7. セキュリティに関する考慮事項

A security AD pointed out that people have been known to forget their laptops after side meetings held in real bars. The organizers of side meetings should therefore remind any attending security ADs (and possibly others) to take their belongings with them after the side meeting ends or the bar closes, whichever happens first.
