1. Introduction
Since its early years, attendance at Internet Engineering Task Force (IETF) face-to-face meetings has grown phenomenally. Many of the attendees are new to the IETF at each meeting, and many of those go on to become regular attendees. When the meetings were smaller, it was relatively easy for a newcomer to get into the swing of things. Today, however, a newcomer meets many more new people, some previously known only as the authors of documents or thought- provoking email messages. This document describes many aspects of the IETF, with the goal of explaining to newcomers how the IETF works. This will give them a warm, fuzzy feeling and enable them to make the meeting and the Working Group discussions more productive for everyone. Of course, it's true that many IETF participants don't go to the face-to-face meetings at all. Instead, they're active on the mailing list of various IETF Working Groups. Since the inner workings of Working Groups can be hard for newcomers to understand, this document provides the mundane bits of information that newcomers will need in order to become active participants. The IETF is always in a state of change. Although the principles in this document are expected to remain largely the same over time, practical details may well have changed by the time you read it; for example, a web-based tool may have replaced an email address for requesting some sort of action. Many types of IETF documentation are mentioned in the Tao, from BCPs to RFCs and FYIs and STDs. BCPs make recommendations for Best Current Practices in the Internet; RFCs are the IETF's main technical documentation series, politely known as "Requests for Comments"; FYIs provide topical and technical overviews that are introductory or appeal to a broad audience; and STDs are RFCs identified as "standards". See Section 8 for more information. The acronyms and abbreviations used in this document are usually expanded in place and are explained fully in Appendix A. This document is intended to obsolete FYI 17, RFC 3160. See Section 3.2.5 for information on what it means for one RFC to obsolete another.
2. Acknowledgements
The original version of this document, published in 1994, was written by Gary Malkin. His knowledge of the IETF, insights, and unmatched writing style set the standard for this later revision, and his contributions to the current document are also much appreciated. Paul Hoffman wrote significant portions of this revision and provided encouragement, expertise, and much-needed guidance. Other contributors include Brian Carpenter, Scott Bradner, Michael Patton, Donald E. Eastlake III, Tony Hansen, Pekka Savola, Lisa Dusseault, the IETF Secretariat, members of the User Services Working Group, and members of the PESCI design team.3. What Is the IETF?
The Internet Engineering Task Force is a loosely self-organized group of people who contribute to the engineering and evolution of Internet technologies. It is the principal body engaged in the development of new Internet standard specifications. The IETF is unusual in that it exists as a collection of happenings, but is not a corporation and has no board of directors, no members, and no dues; see [BCP95], "A Mission Statement for the IETF", for more detail. Its mission includes the following: o Identifying, and proposing solutions to, pressing operational and technical problems in the Internet o Specifying the development or usage of protocols and the near-term architecture to solve such technical problems for the Internet o Making recommendations to the Internet Engineering Steering Group (IESG) regarding the standardization of protocols and protocol usage in the Internet o Facilitating technology transfer from the Internet Research Task Force (IRTF) to the wider Internet community o Providing a forum for the exchange of information within the Internet community between vendors, users, researchers, agency contractors, and network managers The IETF meeting is not a conference, although there are technical presentations. The IETF is not a traditional standards organization, although many specifications are produced that become standards. The IETF is made up of volunteers, many of whom meet three times a year to fulfill the IETF mission.
There is no membership in the IETF. Anyone may register for and attend any meeting. The closest thing there is to being an IETF member is being on the IETF or Working Group mailing lists (see Section 3.3). This is where the best information about current IETF activities and focus can be found. Of course, no organization can be as successful as the IETF is without having some sort of structure. In the IETF's case, that structure is provided by other organizations, as described in [BCP11], "The Organizations Involved in the IETF Standards Process". If you participate in the IETF and read only one BCP, this is the one you should read. In many ways, the IETF runs on the beliefs of its members. One of the "founding beliefs" is embodied in an early quote about the IETF from David Clark: "We reject kings, presidents and voting. We believe in rough consensus and running code". Another early quote that has become a commonly-held belief in the IETF comes from Jon Postel: "Be conservative in what you send and liberal in what you accept". The IETF is really about its members. Because of the unrestrictive membership policies, IETF members come from all over the world and from many different parts of the Internet industry. See Section 4.11 for information about the ways that many people fit into the IETF. One more thing that is important for newcomers: the IETF in no way "runs the Internet", despite what some people mistakenly might say. The IETF makes standards that are often adopted by Internet users, but it does not control, or even patrol, the Internet. If your interest in the IETF is because you want to be part of the overseers, you may be badly disappointed by the IETF.3.1. Humble Beginnings
The first IETF meeting was held in January 1986 at Linkabit in San Diego, with 21 attendees. The 4th IETF, held at SRI in Menlo Park in October 1986, was the first that non-government vendors attended. The concept of Working Groups was introduced at the 5th IETF meeting at the NASA Ames Research Center in California in February 1987. The 7th IETF, held at MITRE in McLean, Virginia, in July 1987, was the first meeting with more than 100 attendees.
The 14th IETF meeting was held at Stanford University in July 1989. It marked a major change in the structure of the IETF universe. The IAB (then Internet Activities Board, now Internet Architecture Board), which until that time oversaw many "task forces", changed its structure to leave only two: the IETF and the IRTF. The IRTF is tasked to consider long-term research problems in the Internet. The IETF also changed at that time. After the Internet Society (ISOC) was formed in January 1992, the IAB proposed to ISOC that the IAB's activities should take place under the auspices of the Internet Society. During INET92 in Kobe, Japan, the ISOC Trustees approved a new charter for the IAB to reflect the proposed relationship. The IETF met in Amsterdam, The Netherlands, in July 1993. This was the first IETF meeting held in Europe, and the US/non-US attendee split was nearly 50/50. About one in three IETF meetings are now held in Europe or Asia, and the number of non-US attendees continues to be high -- about 50%, even at meetings held in the United States.3.2. The Hierarchy
3.2.1. ISOC (Internet Society)
The Internet Society is an international, non-profit, membership organization that fosters the expansion of the Internet. One of the ways that ISOC does this is through financial and legal support of the other "I" groups described here, particularly the IETF. ISOC provides insurance coverage for many of the people in the IETF process and acts as a public relations channel for the times that one of the "I" groups wants to say something to the press. The ISOC is one of the major unsung (and under-supported) heroes of the Internet. Starting in spring 2005, the ISOC also became home base for the IETF's directly employed administrative staff. This is described in more detail in [BCP101], "Structure of the IETF Administrative Support Activity (IASA)". The staff initially includes only an Administrative Director (IAD) who works full-time overseeing IETF meeting planning, operational aspects of support services (the secretariat, IANA (the Internet Assigned Numbers Authority), and the RFC Editor, which are described later in this section), and the budget. He or she (currently it's a he) leads the IETF Administrative Support Activity (IASA), which takes care of tasks such as collecting meeting fees and paying invoices, and also supports the tools for the work of IETF working groups, the IESG, the IAB, and the IRTF (more about these later in this section).
As well as staff, the IASA comprises volunteers and ex officio
members from the ISOC and IETF leadership. The IASA and the IAD are
directed by the IETF Administrative Oversight Committee (IAOC), which
is selected by the IETF community. Here's how all this looks:
Internet Society
|
IAOC

IASA

IAD
Neither the IAD nor the IAOC have any influence over IETF standards
development, which we turn to now.
3.2.2. IESG (Internet Engineering Steering Group)
The IESG is responsible for technical management of IETF activities
and the Internet standards process. It administers the process
according to the rules and procedures that have been ratified by the
ISOC Trustees. However, the IESG doesn't do much direct leadership,
such as the kind you will find in many other standards organizations.
As its name suggests, its role is to set directions rather than to
give orders. The IESG ratifies or corrects the output from the
IETF's Working Groups (WGs), gets WGs started and finished, and makes
sure that non-WG drafts that are about to become RFCs are correct.
The IESG consists of the Area Directors (ADs), who are selected by
the Nominations Committee (which is usually called "the NomCom") and
are appointed for two years. The process for choosing the members of
the IESG is detailed in [BCP10], "IAB and IESG Selection,
Confirmation, and Recall Process: Operation of the Nominating and
Recall Committees".
The current areas and abbreviations are shown below.
Area Description
-----------------------------------------------------------------
Applications (APP) Protocols seen by user programs, such as
email and the web
General (GEN) Catch-all for WGs that don't fit in other
areas (which is very few)
Internet (INT) Different ways of moving IP packets and
DNS information
Operations and Operational aspects, network monitoring, Management (OPS) and configuration Real-time Delay-sensitive interpersonal Applications and communications Infrastructure (RAI) Routing (RTG) Getting packets to their destinations Security (SEC) Authentication and privacy Transport (TSV) Special services for special packets Because the IESG has a great deal of influence on whether Internet Drafts become RFCs, many people look at the ADs as somewhat godlike creatures. IETF participants sometimes reverently ask Area Directors for their opinion on a particular subject. However, most ADs are nearly indistinguishable from mere mortals and rarely speak from mountaintops. In fact, when asked for specific technical comments, the ADs may often defer to members at large whom they feel have more knowledge than they do in that area. The ADs for a particular area are expected to know more about the combined work of the WGs in that area than anyone else. On the other hand, the entire IESG reviews each Internet Draft that is proposed to become an RFC. Any AD may record a "DISCUSS" ballot position against a draft if he or she has serious concerns. If these concerns cannot be resolved by discussion, an override procedure is defined such that at least two IESG members must express concerns before a draft can be blocked from moving forward. These procedures help ensure that an AD's "pet project" doesn't make it onto the standards track if it will have a negative effect on the rest of the IETF protocols and that an AD's "pet peeve" cannot indefinitely block something. This is not to say that the IESG never wields power. When the IESG sees a Working Group veering from its charter, or when a WG asks the IESG to make the WG's badly designed protocol a standard, the IESG will act. In fact, because of its high workload, the IESG usually moves in a reactive fashion. It eventually approves most WG requests for Internet Drafts to become RFCs, and usually only steps in when something has gone very wrong. Another way to think about this is that the ADs are selected to think, not to just run the process. The quality of the IETF standards comes both from the review they get in the Working Groups and the scrutiny that the WG review gets from the ADs.
The IETF is run by rough consensus, and it is the IESG that judges whether a WG has come up with a result that has community consensus. (See Section 5.2 for more information on WG consensus.) Because of this, one of the main reasons that the IESG might block something that was produced in a WG is that the result did not really gain consensus in the IETF as a whole, that is, among all of the Working Groups in all areas. For instance, the result of one WG might clash with a technology developed in a different Working Group. An important job of the IESG is to watch over the output of all the WGs to help prevent IETF protocols that are at odds with each other. This is why ADs are supposed to review the drafts coming out of areas other than their own.3.2.3. IAB (Internet Architecture Board)
The IAB is responsible for keeping an eye on the "big picture" of the Internet, and it focuses on long-range planning and coordination among the various areas of IETF activity. The IAB stays informed about important long-term issues in the Internet, and it brings these topics to the attention of people it thinks should know about them. The IAB web site is at http://www.iab.org/. IAB members pay special attention to emerging activities in the IETF. When a new IETF Working Group is proposed, the IAB reviews its charter for architectural consistency and integrity. Even before the group is chartered, the IAB members are more than willing to discuss new ideas with the people proposing them. The IAB also sponsors and organizes the Internet Research Task Force and convenes invitational workshops that provide in-depth reviews of specific Internet architectural issues. Typically, the workshop reports make recommendations to the IETF community and to the IESG. The IAB also: o Approves NomCom's IESG nominations o Acts as the appeals board for appeals against IESG actions o Appoints and oversees the RFC Editor o Approves the appointment of the IANA o Acts as an advisory body to ISOC o Oversees IETF liaisons with other standards bodies
Like the IESG, the IAB members are selected for multi-year positions by the NomCom and are approved by the ISOC Board of Trustees.3.2.4. IANA (Internet Assigned Numbers Authority)
The core registrar for the IETF's activities is the IANA. Many Internet protocols require that someone keep track of protocol items that were added after the protocol came out. Typical examples of the kinds of registries needed are for TCP port numbers and MIME types. The IAB has designated the IANA organization to perform these tasks, and the IANA's activities are financially supported by ICANN, the Internet Corporation for Assigned Names and Numbers. Ten years ago, no one would have expected to see the IANA mentioned on the front page of a newspaper. IANA's role had always been very low key. The fact that IANA was also the keeper of the root of the domain name system forced it to become a much more public entity, one that was badly maligned by a variety of people who never looked at what its role was. Nowadays, the IETF is generally no longer involved in the IANA's domain name and IP address assignment functions, which are overseen by ICANN. Even though being a registrar may not sound interesting, many IETF participants will testify to how important IANA has been for the Internet. Having a stable, long-term repository run by careful and conservative operators makes it much easier for people to experiment without worrying about messing things up. IANA's founder, Jon Postel, was heavily relied upon to keep things in order while the Internet kept growing by leaps and bounds, and he did a fine job of it until his untimely death in 1998.3.2.5. RFC Editor
The RFC Editor edits, formats, and publishes Internet Drafts as RFCs, working in conjunction with the IESG. An important secondary role is to provide one definitive repository for all RFCs (see http://www.rfc-editor.org). Once an RFC is published, it is never revised. If the standard it describes changes, the standard will be re-published in another RFC that "obsoletes" the first. One of the most popular misconceptions in the IETF community is that the role of the RFC Editor is performed by IANA. In fact, the RFC Editor is a separate job, although both the RFC Editor and IANA involved the same people for many years. The IAB approves the organization that will act as RFC Editor and the RFC Editor's general policy. The RFC Editor is funded by IASA and can be contacted by email at mailto:rfc-editor@rfc-editor.org.
3.2.6. IETF Secretariat
There are, in fact, a few people who are paid to maintain the IETF. The IETF Secretariat provides day-to-day logistical support, which mainly means coordinating face-to-face meetings and running the IETF-specific mailing lists (not the WG mailing lists). The Secretariat is also responsible for keeping the official Internet Drafts directory up to date and orderly, maintaining the IETF web site, and helping the IESG do its work. It provides various tools for use by the community and the IESG. The IETF Secretariat is under contract to IASA, which in turn is financially supported by the fees of the face-to-face meetings.3.3. IETF Mailing Lists
Anyone who plans to attend an IETF meeting should join the IETF announcement mailing list, mailto:ietf-announce@ietf.org. This is where all of the meeting information, RFC announcements, and IESG Protocol Actions and Last Calls are posted. People who would like to "get technical" may also join the IETF general discussion list, ietf@ietf.org. This is where discussions of cosmic significance are held (Working Groups have their own mailing lists for discussions related to their work). Another mailing list, mailto:i-d- announce@ietf.org, announces each new version of every Internet Draft as it is published. Subscriptions to these and other IETF-run mailing lists are handled by a program called "mailman". Mailman can be somewhat finicky about the format of subscription messages, and sometimes interacts poorly with email programs that make all email messages into HTML files. Mailman will treat you well, however, if you format your messages just the way it likes. To join the IETF announcement list, for example, send email to mailto:ietf-announce-request@ietf.org. Enter the word 'subscribe' (without the quotes) in the Subject line of the message and in the message body. To join the IETF discussion list, send email to <mailto:ietf-request@ietf.org> and enter the word 'subscribe' as explained above. If you decide to withdraw from either list, use the word 'unsubscribe'. Your messages to mailman should have nothing other than the commands 'subscribe' or 'unsubscribe' in them. Both lists are archived on the IETF web site, http://www.ietf.org/maillist.html.
Do not, ever, under any circumstances, for any reason, send a request to join a list to the list itself! The thousands of people on the list don't need, or want, to know when a new person joins. Similarly, when changing email addresses or leaving a list, send your request only to the "-request" address, not to the main list. This means you!! The IETF discussion list is unmoderated. This means that all can express their opinions about issues affecting the Internet. However, it is not a place for companies or individuals to solicit or advertise, as noted in [BCP45], "IETF Discussion List Charter". It is a good idea to read the whole RFC (it's short!) before posting to the IETF discussion list. Actually, the list does have two "sergeants at arms" who keep an eye open for inappropriate postings, and there is a process for banning persistent offenders from the list, but fortunately this is extremely rare. Only the Secretariat and certain IETF office holders can approve messages sent to the announcement list, although those messages can come from a variety of people. Even though the IETF mailing lists "represent" the IETF membership at large, it is important to note that attending an IETF meeting does not mean you'll be automatically added to either mailing list.4. IETF Meetings
The computer industry is rife with conferences, seminars, expositions, and all manner of other kinds of meetings. IETF face- to-face meetings are nothing like these. The meetings, held three times a year, are week-long "gatherings of the tribes" whose primary goal is to reinvigorate the WGs to get their tasks done, and whose secondary goal is to promote a fair amount of mixing between the WGs and the areas. The cost of the meetings is paid by the people attending and by the corporate host for each meeting (if any), although IASA kicks in additional funds for things such as the audio broadcast of some Working Group sessions. For many people, IETF meetings are a breath of fresh air when compared to the standard computer industry conferences. There is no exposition hall, few tutorials, and no big-name industry pundits. Instead, there is lots of work, as well as a fair amount of time for socializing. IETF meetings are of little interest to sales and marketing folks, but of high interest to engineers and developers. Most IETF meetings are held in North America, because that's where most of the participants are from; however, meetings are held on other continents about once every year. The past few meetings have
had about 1,300 attendees. There have been more than 65 IETF meetings so far, and a list of upcoming meetings is available on the IETF web pages, http://www.ietf.org/meetings/0mtg-sites.txt. Newcomers to IETF face-to-face meetings are often in a bit of shock. They expect them to be like other standards bodies, or like computer conferences. Fortunately, the shock wears off after a day or two, and many new attendees get quite animated about how much fun they are having. One particularly jarring feature of recent IETF meetings is the use of wireless Internet connections throughout the meeting space. It is common to see people in a WG meeting apparently reading email or perusing the web during presentations they find uninteresting. Remember, however, that they may also be consulting the drafts under discussion, looking up relevant material online, or following another meeting using instant messaging.4.1. Registration
To attend an IETF meeting, you have to register and you have to pay the registration fee. The meeting site and advance registration are announced about two months ahead of the meeting -- earlier if possible. An announcement goes out via email to the IETF-announce mailing list, and information is posted on the IETF web site, http://www.ietf.org, that same day. To pre-register, you must submit your registration on the web. You may pre-register and pre-pay, pre-register and return to the web site later to pay with a credit card, pre-register and pay on-site at the meeting, or register and pay on-site. To get a lower registration fee, you must pay by the early registration deadline (about one week before the meeting). The registration fee covers all of the week's meetings, the Sunday evening reception (cash bar), daily continental breakfasts, and afternoon coffee and snack breaks. Credit card payments on the web are encrypted and secure, or, if you prefer, you can use Pretty Good Privacy (PGP) to send your payment information to the Registrar (mailto:ietf-registrar@ietf.org). Registration is open throughout the week of the meeting. However, the Secretariat highly recommends that attendees arrive for early registration, usually beginning at noon on Sunday and continuing throughout the Sunday evening reception. The reception is a popular event where you can get a small bite to eat and socialize with other early arrivals. Registered attendees (and there aren't any other kind) receive a registration packet. It contains much useful information, including a general orientation sheet, the most recent agenda, and a name tag.
Attendees who pre-paid will also find their receipt in their packet. It's worth noting that neither attendee names and addresses nor IETF mailing lists are ever offered for sale. In your registration packet is a sheet titled "Note Well". You should indeed read it carefully because it lays out the rules for IETF intellectual property rights. If you need to leave messages for other attendees, you can do so at the cork boards that are often near the registration desk. These cork boards will also have last-minute meeting changes and room changes. You can also turn in lost-and-found items to the registration desk. At the end of the meeting, anything left over from the lost and found will usually be turned over to the hotel or brought back to the Secretariat's office. Incidentally, the IETF registration desk is often a convenient place to arrange to meet people. If someone says "meet me at registration", they almost always mean the IETF registration desk, not the hotel registration desk.4.2. Take the Plunge and Stay All Week!
IETF meetings last from Monday morning through Friday lunchtime. Associated meetings often take place on the preceding or following weekends. It is best to plan to be present the whole week, to benefit from cross-fertilization between Working Groups and from corridor discussions. As noted below, the agenda is fluid, and there have been many instances of participants missing important sessions due to last-minute scheduling changes after their travel plans were fixed. Being present the whole week is the only way to avoid this annoyance. If you cannot find meetings all week to interest you, you can still make the most of the IETF meeting by working between sessions. Most IETF attendees carry laptop computers, and it is common to see many of them in the terminal room or in the hallways working during meeting sessions. There is often good wireless Internet coverage in many places of the meeting venue (restaurants, coffee shops, and so on), so catching up on email when not in meetings is a fairly common task for IETFers.
4.3. Newcomer Training
Newcomers are encouraged to attend the Newcomer Training, which is especially designed for first-time attendees. The orientation is organized and conducted by the IETF EDU team and is intended to provide useful introductory information. The session covers what's in the attendee packets, what all the dots on name tags mean, the structure of the IETF, and many other essential and enlightening topics for new IETFers. Immediately following the Newcomers' Training is the IETF Standards Process Orientation. This session demystifies much of the standards process by explaining what stages a document has to pass through on its way to becoming a standard, and what has to be done to advance to the next stage. There is usually ample time at the end for questions. The Secretariat provides hard copies of the slides of the "IETF Structure and Internet Standards Process" presentation -- these very useful slides are also available online at www.ietf.org under "Educational Materials". The orientation is normally held on Sunday afternoon, along with tutorials of interest to newcomers and old-timers alike. Check the agenda for exact times and locations.4.4. Dress Code
Since attendees must wear their name tags, they must also wear shirts or blouses. Pants or skirts are also highly recommended. Seriously though, many newcomers are often embarrassed when they show up Monday morning in suits, to discover that everybody else is wearing T- shirts, jeans (shorts, if weather permits) and sandals. There are those in the IETF who refuse to wear anything other than suits. Fortunately, they are well known (for other reasons) so they are forgiven this particular idiosyncrasy. The general rule is "dress for the weather" (unless you plan to work so hard that you won't go outside, in which case, "dress for comfort" is the rule!).4.5. Seeing Spots Before Your Eyes
Some of the people at the IETF will have a little colored dot on their name tag. A few people have more than one. These dots identify people who are silly enough to volunteer to do a lot of extra work. The colors have the meanings shown here.
Color Meaning -------------------------------------- Blue Working Group/BOF chair Green Host group Red IAB member Yellow IESG member Orange Nominating Committee member (Members of the press wear orange-tinted badges.) Local hosts are the people who can answer questions about the terminal room, restaurants, and points of interest in the area. It is important that newcomers to the IETF not be afraid to strike up conversations with people who wear these dots. If the IAB and IESG members and Working Group and BOF chairs didn't want to talk to anybody, they wouldn't be wearing the dots in the first place.4.6. Terminal Room
One of the most important (depending on your point of view) things the host does is provide Internet access for the meeting attendees. In general, wired and wireless connectivity is excellent. This is entirely due to the Olympian efforts of the local hosts and their ability to beg, borrow, and steal. The people and companies that donate their equipment, services, and time are to be heartily congratulated and thanked. Although preparation far in advance of the meeting is encouraged, there may be some unavoidable "last minute" things that can be accomplished in the terminal room. It may also be useful to people who need to make trip reports or status reports while things are still fresh in their minds. You need to be wearing your badge in order to get into the terminal room. The terminal room provides lots of power strips, lots of Ethernet ports for laptops, wireless (for the people who don't need Ethernet but want power), usually a printer for public use, and sometimes workstations. What it doesn't provide are terminals; the name is historical. The help desk in the terminal room is a good place to ask questions about network failures, although they might point you off to different networking staff.4.7. Meals and Other Delights
Marshall Rose once remarked that the IETF was a place to go for "many fine lunches and dinners". Although it is true that some people eat very well at the IETF, they find the food on their own; lunches and
dinners are not included in the registration fee. The Secretariat does provide appetizers at the Sunday evening reception (not meant to be a replacement for dinner), continental breakfast every morning, and (best of all) cookies, brownies, and other yummies during afternoon breaks. If you prefer to get out of the hotel for meals, the local host usually provides a list of places to eat within easy reach of the meeting site.4.8. Social Event
Another of the most important things organized and managed by the host is the IETF social event. Sometimes, the social event is a computer- or high-tech-related event. At one Boston IETF, for example, the social was dinner at the Computer Museum. Other times, the social might be a dinner cruise or a trip to an art gallery. Note, however, that not all IETF meetings have social events. Newcomers to the IETF are encouraged to attend the social event. All are encouraged to wear their name tags and leave their laptops behind. The social event is designed to give people a chance to meet on a social, rather than technical, level.4.9. Agenda
The agenda for the IETF meetings is a very fluid thing. It is typically sent to the IETF announcement list a few times prior to the meeting, and it is also available on the web. The final agenda is included in the registration packets. Of course, "final" in the IETF doesn't mean the same thing as it does elsewhere in the world. The final agenda is simply the version that went to the printer. The Secretariat will post agenda changes on the bulletin board near the IETF registration desk (not the hotel registration desk). These late changes are not capricious: they are made "just in time" as session chairs and speakers become aware of unanticipated clashes. The IETF is too dynamic for agendas to be tied down weeks in advance. Assignments for breakout rooms (where the Working Groups and BOFs meet) and a map showing the room locations are also shown on the agenda. Room assignments can change as the agenda changes. Some Working Groups meet multiple times during a meeting, and every attempt is made to have a Working Group meet in the same room for each session.
4.10. EDU to the Rescue
If certain aspects of the IETF still mystify you (even after you finish reading the Tao), you'll want to drop in on the on-site training offered by the Education (EDU) team. These informal classes are designed for newcomers and seasoned IETFers alike. In addition to the Newcomer Training, the EDU team offers workshops for document editors and Working Group chairs, plus an in-depth security tutorial that's indispensable for both novices and longtime IETF attendees. EDU sessions are generally held on Sunday afternoons. You'll find more about the EDU team at http://edu.ietf.org/.4.11. Where Do I Fit In?
The IETF is different things to different people. There are many people who have been very active in the IETF who have never attended an IETF meeting. You should not feel obligated to come to an IETF meeting just to get a feel for the IETF. The following guidelines (based on stereotypes of people in various industries) might help you decide whether you actually want to come and, if so, what might be the best use of your time at your first meeting.4.11.1. IS Managers
As discussed throughout this document, an IETF meeting is nothing like any trade show you have attended. IETF meetings are singularly bad places to go if your intention is to find out what will be hot in the Internet industry next year. You can safely assume that going to Working Group meetings will confuse you more than it will help you understand what is happening, or will be happening, in the industry. This is not to say that no one from the industry should go to IETF meetings. As an IS manager, you might want to consider sending specific people who are responsible for technologies that are under development in the IETF. As these people read the current Internet Drafts and the traffic on the relevant Working Group lists, they will get a sense of whether or not their presence would be worthwhile for your company or for the Working Groups.4.11.2. Network Operators and ISPs
Running a network is hard enough without having to grapple with new protocols or new versions of the protocols with which you are already dealing. If you work for the type of network that is always using the very latest hardware and software, and you are following the relevant Working Groups in your copious free time, you could certainly find participating in the IETF valuable. A fair amount of IETF work also covers many other parts of operations of ISPs and
large enterprises, and the input of operators is quite valuable to keep this work vibrant and relevant. Many of the best operations documents from the IETF come from real-world operators, not vendors and academics.4.11.3. Networking Hardware and Software Vendors
The image of the IETF being mostly ivory tower academics may have been true in the past, but the jobs of typical attendees are now in industry. In most areas of the IETF, employees of vendors are the ones writing the protocols and leading the Working Groups, so it's completely appropriate for vendors to attend. If you create Internet hardware or software, and no one from your company has ever attended an IETF meeting, it behooves you to come to a meeting if for no other reason than to tell the others how relevant the meeting was or was not to your business. This is not to say that companies should close up shop during IETF meeting weeks so everyone can go to the meeting. Marketing folks, even technical marketing folks, are usually safe in staying away from the IETF as long as some of the technical people from the company are at the meeting. Similarly, it isn't required, or likely useful, for everyone from a technical department to go, particularly if they are not all reading the Internet Drafts and following the Working Group mailing lists. Many companies have just a few designated meeting attendees who are chosen for their ability to do complete and useful trip reports. In addition, many companies have internal coordination efforts and a standards strategy. If a company depends on the Internet for some or all of its business, the strategy should probably cover the IETF.4.11.4. Academics
IETF meetings are often excellent places for computer science folks to find out what is happening in the way of soon-to-be-deployed protocols. Professors and grad students (and sometimes overachieving undergrads) who are doing research in networking or communications can get a wealth of information by following Working Groups in their specific fields of interest. Wandering into different Working Group meetings can have the same effect as going to symposia and seminars in your department. Researchers are also, of course, likely to be interested in IRTF activities.4.11.5. Computer Trade Press
If you're a member of the press and are considering attending IETF, we've prepared a special section of the Tao just for you -- please see Section 10.2.
4.12. Proceedings
IETF proceedings are compiled in the two months following each meeting and are available on the web and on CD. Be sure to look through a copy -- the proceedings are filled with information about IETF that you're not likely to find anywhere else. For example, you'll find snapshots of most WG charters at the time of the meeting, giving you a better understanding of the evolution of any given effort. The proceedings sometimes start with an informative (and highly entertaining) message. Each volume contains the final (hindsight) agenda, an IETF overview, area and Working Group reports, and slides from the protocol and technical presentations. The Working Group reports and presentations are sometimes incomplete, if the materials haven't been turned in to the Secretariat in time for publication. An attendee list is also included, which contains names and affiliations as provided on the registration form. For information about obtaining copies of the proceedings, see the web listing at http://www.ietf.org/proceedings/directory.html.4.13. Other General Things
The IETF Secretariat, and IETFers in general, are very approachable. Never be afraid to approach someone and introduce yourself. Also, don't be afraid to ask questions, especially when it comes to jargon and acronyms. Hallway conversations are very important. A lot of very good work gets done by people who talk together between meetings and over lunches and dinners. Every minute of the IETF can be considered work time (much to some people's dismay). A "bar BOF" is 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. It's unwise to get between a hungry IETFer (and there isn't any other kind) and coffee break brownies and cookies, no matter how interesting a hallway conversation is. IETFers are fiercely independent. It's safe to question opinions and offer alternatives, but don't expect an IETFer to follow orders.
The IETF meetings, and the plenary session in particular, are not places for vendors to try to sell their wares. People can certainly answer questions about their company and its products, but bear in mind that the IETF is not a trade show. This does not preclude people from recouping costs for IETF-related T-shirts, buttons, and pocket protectors. There is always a "materials distribution table" near the registration desk. This desk is used to make appropriate information available to the attendees (e.g., copies of something discussed in a Working Group session, descriptions of online IETF-related information). Please check with the Secretariat before placing materials on the desk; the Secretariat has the right to remove material that he or she feels is not appropriate. If you rely on your laptop during the meeting, it is a good idea to bring an extra battery. It is not always easy to find a spare outlet in some meeting rooms, and using the wireless access can draw down your battery faster than you might expect. If you are sitting near a power-strip in a meeting room, expect to be asked to plug and unplug for others around you. Many people bring an extension cord with spare outlets, which is a good way to make friends with your neighbor in a meeting. If you need an outlet adapter, you should try to buy it in advance because the one you need is usually easier to find in your home country.
