INTRODUCTION This document defines guidelines and procedures for Internet Engineering Task Force working groups. The Internet is a loosely- organized international collaboration of autonomous, interconnected networks; it supports host-to-host communication through voluntary adherence to open protocols and procedures defined by Internet Standards, a collection of which are commonly known as "the TCP/IP protocol suite". The Internet Standards Process is defined in [1]. Development and review of potential Internet Standards from all sources is conducted by the Internet Engineering Task Force (IETF). The IETF is a large, open community of network designers, operators, vendors, users, and researchers concerned with the Internet and the technology used on it. The IETF is managed by its Internet Engineering Steering Group (IESG) whose membership includes an IETF Chair, responsible for oversight of general IETF operations, and Area Directors, each of whom is responsible for a set of IETF activities and working groups. The IETF Executive Director and IESG Secretary are ex-officio participants, as are the IAB Chair and a designated Internet Architecture Board (IAB) member. At present there are 10 areas, though the number and purview of areas changes over time: User Services (USV) Applications (APP) Service Applications (SAP) Transport Services (TSV) Internet (INT) Routing (RTG) Network Management (MGT) Operational Requirements (OPS) Security (SEC) Standards & Processes (STD)Huizer & Crocker [Page 2]
RFC 1603 IETF Working Group Guidelines March 1994 Most areas have an advisory group or directorate. The specific name and the details of the role for each group differs from area to area, but the primary intent is that the group assist the Area Director, e.g., with the review of specifications produced in the area. An advisory group is formed by an Area Director (AD) and comprises experienced members of the IETF and technical community represented by the area. A small IETF Secretariat provides staff and administrative support for the operation of the IETF. The primary activities of the IETF are performed by committees known as working groups. There are currently more than 60 of these. Working groups tend to have a narrow focus and a lifetime bounded by completion of a specific task, although there are exceptions. There is no formal membership in the IETF. Participation is open to all. This participation may be by on-line contribution, attendance at face-to-face sessions, or both. Anyone from the Internet community who has the time and interest is urged to participate in IETF meetings and any of its on-line working group discussions. Participation is by individual technical contributors, rather than by formal representatives of organizations. This document defines procedures and guidelines for formation and operation of working groups in the IETF. It defines the relations of working groups to other bodies within the IETF. The duties of working group Chairs and Area Directors with respect to the operation of the working group are also defined. The document uses: "shall", "will", "must" and "is required" where it describes steps in the process that are essential, and uses: "suggested", "should" and "may" are where guidelines are described that are not essential, but are strongly recommended to help smooth WG operation.1.1. IETF approach to standardization The reader is encouraged to study The Internet Standards Process [1]. Familiarity with this document is essential for a complete understanding of the philosophy, procedures and guidelines described in this document. The goals of the process are summarized in [1]: "In general, an Internet Standard is a specification that is stable and well-understood, is technically competent, has multiple, independent, and interoperable implementations with operational experience, enjoys significant public support, and is recognizably useful in some or all parts of the Internet. ...Huizer & Crocker [Page 3]
RFC 1603 IETF Working Group Guidelines March 1994 "In outline, the process of creating an Internet Standard is straightforward: a specification undergoes a period of development and several iterations of review by the Internet community and perhaps revision based upon experience, is adopted as a Standard by the appropriate body (see below), and is published. "In practice, the process is somewhat more complicated, due to (1) the number and type of possible sources for specifications; (2) the need to prepare and revise a specification in a manner that preserves the interests of all of the affected parties; (3) the importance of establishing widespread community agreement on its technical content; and (4) the difficulty of evaluating the utility of a particular specification for the Internet community. ... "These procedures are explicitly aimed at developing and adopting generally-accepted practices. Thus, a candidate for Internet standardization is implemented and tested for correct operation and interoperability by multiple, independent parties, and utilized in increasingly demanding environments, before it can be adopted as an Internet Standard." The IETF standardization process has been marked by informality. As the community of participation has grown it has become necessary to document procedures, while continuing to avoid unnecessary bureaucracy. This goals of this balancing act are summarized in [1] as: "The procedures that are described here provide a great deal of flexibility to adapt to the wide variety of circumstances that occur in the Internet standardization process. Experience has shown this flexibility to be vital in achieving the following goals for Internet standardization: * high quality, * prior implementation and testing, * openness and fairness, and * timeliness."1.2. Acknowledgments Much of this document is due to the copy-and-paste function of a word processor. Several passages have been taken from the documents cited in the reference section. The POISED WG provided discussion and comments. Three people deserve special mention, as especially large chunks of their documents have been integrated into this one: VintHuizer & Crocker [Page 4]
RFC 1603 IETF Working Group Guidelines March 1994 Cerf [7] from whom we borrowed the description of the IETF; and Greg Vaudreuil and Steve Coya who provided several paragraphs. Also, John Stewart and Steve Crocker did a truly stellar job of proof-reading. However, all the errors you'll find are probably ours.2. WORKING GROUP (WG) FORMATION IETF working groups (WGs) are the primary mechanism for development of IETF specifications and guidelines, many of which are intended as standards or recommendations. A working group may be established at the initiative of an Area Director (AD) or it may be initiated by an individual or group of individuals. Anyone interested in creating an IETF working group must obtain the advice and consent of the appropriate IETF Area Director under whose direction the working group would fall and must proceed through the formal steps detailed in this section. A working group is typically created to address a specific problem or produce a deliverable (a guideline, standards specification, etc.) and is expected to be short-lived in nature. Upon completion of its goals and achievement of its objectives, the working group as a unit is terminated. Alternatively at the discretion of the IESG, Area Director, the WG Chair and the WG participants, the objectives or assignment of the working group may be extended by enhancing or modifying the working group's charter.2.1. Criteria for formation When determining whether it is appropriate to create a working group, the Area Director and the IESG will consider several issues: - Are the issues that the working group plans to address clear and relevant for the Internet community? - Are the goals specific and reasonably achievable, and achievable within the time frame specified by the milestones? - What are the risks and urgency of the work, to determine the level of attention required? - Do the working group's activities overlap with those of another working group? If so, it may still be appropriate to create the working group, but this question must be considered carefully by the Area Directors as subdividing efforts often dilutes the available technical expertise.Huizer & Crocker [Page 5]
RFC 1603 IETF Working Group Guidelines March 1994 - Is there sufficient interest and expertise in the working group's topic with at least several people willing to expend the effort to produce the desired result (e.g., a protocol specification)? Working groups require considerable effort, including management of the working group process, editing of working group documents, and contribution to the document text. IETF experience suggests that these roles typically cannot all be handled by one person; four or five active participants are typically required. - Does a base of interested consumers (end users) appear to exist for the planned work? Consumer interest can be measured by participation of end-users within the IETF process, as well as by less direct means. Considering the above criteria, the Area Director will decide whether to pursue the formation of the group through the chartering process.2.2. Charter The formation of a working group requires a charter which is primarily negotiated between a prospective working group Chair and the relevant Area Director, although final approval is made by the IESG and all charters are reviewed by the Internet Architecture Board (IAB). A charter is a contract between a working group and the IETF to perform a set of tasks. A charter: 1. Lists relevant administrative aspects of the working group; 2. Specifies the direction or objectives of the working group and describes the approach that will be taken to achieve the goals; and 3. Enumerates a set of milestones together with time frames for their completion. When the prospective Chair, the Area Director and the IESG Secretary are satisfied with the charter form and content, it becomes the basis for forming a working group. The AD may require an initial draft of a charter to be available prior to holding an exploratory Birds of a Feather (BOF) meeting, as described below. Charters may be renegotiated periodically to reflect the current status, organization or goals of the working group. Hence, a charter is a contract between the IETF and the working group which is committing to meet explicit milestones and delivering concrete "products".Huizer & Crocker [Page 6]
RFC 1603 IETF Working Group Guidelines March 1994 Specifically, each charter consists of 6 sections: Working group name A working group name should be reasonably descriptive or identifiable. Additionally, the group shall define an acronym (maximum 8 printable ASCII characters) to reference the group in the IETF directories, mailing lists, and general documents. Chair(s) The working group may have one or two Chair(s) to perform the administrative functions of the group. The email address(es) of the Chair(s) shall be included. Area and Area Director(s) The name of the IETF area with which the working group is affiliated and the name and electronic mail address of the associated Area Director. Mailing list It is required that an IETF working group have a general Internet mailing list. Most of the work of an IETF working group will be conducted that. The charter shall include: The address to which a participant sends a subscription request and the procedures to follow when subscribing, The address to which a participant sends submissions and special procedures, if any, and The location of the mailing list archive, if any. A message archive should be maintained in a public place which can be accessed via FTP. The ability to retrieve from the archive via electronic mail requests also is recommended. Additionally, the address: ietf-archive@cnri.reston.va.us shall be included on the mailing list.Huizer & Crocker [Page 7]
RFC 1603 IETF Working Group Guidelines March 1994 NOTE: It is strongly suggested that the mailing list be on a host directly connected to the IP Internet to facilitate use of the SMTP expansion command (EXPN) and to allow mail archive access via FTP, gopher and the like in keeping with the general IETF rule for openness. If this is not possible, the message archive and membership of the list must be made available to those who request it by sending a message to the list-request alias. Description of working group The focus and intent of the group shall be set forth briefly. By reading this section alone, an individual should be able to decide whether this group is relevant to their own work. The first paragraph must give a brief summary of the problem area, basis, goal(s) and approach(es) planned for the working group. This paragraph will frequently be used as an overview of the working group's effort. The terms "they", "them" and "their" are used in this document as third-person singular pronouns. To facilitate evaluation of the intended work and to provide on-going guidance to the working group, the charter shall describe the problem being solved and shall discuss objectives and expected impact with respect to: - Architecture - Operations - Security - Network management - Transition (where applicable) Goals and milestones The working group charter must establish a timetable for work. While this may be re-negotiated over time, the list of milestones and dates facilitates the Area Director's tracking of working group progress and status, and it is indispensable to potential participants identifying the critical moments for input. Milestones shall consist of deliverables that can be qualified as showing specific achievement; e.g., "Internet-Draft finished" is fine, but "discuss via email" is not. It is helpful to specify milestones for every 3-6 months, so that progress can be gauged easily. This milestone list is expected to be updated periodically. Updated milestones are re-negotiated with the Area Director and the IESG, as needed, and then are submitted to the IESG Secretary:Huizer & Crocker [Page 8]
RFC 1603 IETF Working Group Guidelines March 1994 IESG-secretary@cnri.reston.va.us An example of a WG charter is inAppendix A.2.3. Charter review & approval Working groups often comprise technically competent participants who are not familiar with the history of Internet architecture or IETF processes. This can, unfortunately, lead to good working group consensus about a bad design. To facilitate working group efforts, an Area Director may assign an Area Consultant from among the ranks of senior IETF participants. (Area Consultants are described in the section of Staff Roles.) At the discretion of the AD, approval of a new WG may be withheld in the absence of sufficient Consultant resources. Once the Area Director (and the Area Directorate, as the AD deems appropriate) has approved the working group charter, the charter is submitted for review by the IAB and approval by the Internet Engineering Steering Group using the criteria described previously. The Internet Architecture Board (IAB) will review the charter of the proposed WG to determine the relationship of the proposed work to the overall architecture of the Internet Protocol Suite. The approved charter is submitted to the IESG Secretary who records and enters the information into the IETF tracking database and returns the charter in a form formatted by the database. The working group is announced to the IETF mailing list by the IESG Secretary.2.4. Birds of a feather (BOF) Often it is not clear whether an issue merits the formation of a working group. To facilitate exploration of the issues the IETF offers the possibility of a Birds of a Feather (BOF) session, as well as the early formation of an email list for preliminary discussion. Alternatively, a BOF may serve as a forum for a single presentation or discussion, without any intent to form a working group. A BOF is a session at an IETF meeting which permits "market research" and technical "brainstorming". Any individual may request permission to hold a BOF on a subject. The request must be filed with the relevant Area Director. The person who requests the BOF is usually appointed as Chair of the BOF. The Chair of the BOF is also responsible for providing a report on the outcome of the BOF.Huizer & Crocker [Page 9]
RFC 1603 IETF Working Group Guidelines March 1994 The AD may require the conduct of email discussion, prior to authorizing a BOF. This permits initial exchanges and sharing of framework, vocabulary and approaches, in order to make the time spent in the BOF more productive. The AD may require that a BOF be held, prior to establishing a working group, and the AD may require that there be a draft of the WG charter prior to holding a BOF. Usually the outcome of a BOF will be one of the following: - There was enough interest and focus in the subject to warrant the formation of a WG; - The discussion came to a fruitful conclusion, with results to be written down and published, however there is no need to establish a WG; or - There was not enough interest in the subject to warrant the formation of a WG. There is an increasing demand for BOF sessions at IETF meetings. Therefore the following rules apply for BOFs: - All BOFs must have the approval of the appropriate Area Director. The Secretariat will NOT schedule or allocate time slots without the explicit approval of the Area Director. - The purpose of a BOF is to conduct a single, brief discussion or to ascertain interest and establish goals for a working group. All BOF organizers are required to submit a brief written report of what transpired during the BOF session together with a roster of attendees to the IESG Secretary for inclusion in the Proceedings. - A BOF may be held only once (ONE slot at one IETF Plenary meeting). - Under unusual circumstances an Area Director may, at their discretion, allow a BOF to meet for a second time. Typically (though not a requirement) this is to develop a charter to be submitted to the IESG. - BOFs are not permitted to meet three times.Huizer & Crocker [Page 10]
RFC 1603 IETF Working Group Guidelines March 1994 - A BOF may be held for single-event discussion, or may pursue creation of normal IETF working groups for on-going interactions and discussions. When the request for a BOF comes from a formally-constituted group, rather than from an individual, the rules governing the handling of the request are the same as for all other BOFs and working groups. - When necessary, WGs will be given priority for meeting space over BOFs.3. WORKING GROUP OPERATION The IETF has basic requirements for open and fair participation and for thorough consideration of technical alternatives. Within those constraints, working groups are autonomous and each determines most of the details of its own operation with respect to session participation, reaching closure, etc. The core rule for operation is that acceptance or agreement is achieved via working group "rough consensus". A number of procedural questions and issues will arise over time, and it is the function of the Working Group Chair to manage the group process, keeping in mind that the overall purpose of the group is to make progress towards reaching rough consensus in realizing the working group's goals and objectives. There are few hard and fast rules on organizing or conducting working group activities, but a set of guidelines and practices have evolved over time that have proven successful. These are listed here, with actual choices typically determined by the working group participants and the Chair.3.1. Session planning For coordinated, structured WG interactions, the Chair must publish a draft agenda well in advance of the actual session. The agenda needs to contain at least: - The items for discussion; - The estimated time necessary per item; and - A clear indication of what documents the participants will need to read before the session in order to be well prepared.Huizer & Crocker [Page 11]
RFC 1603 IETF Working Group Guidelines March 1994 Publication shall include sending a copy to the working group mailing list and to the IETF-Announce list. Notices for the IETF-Announce list should be sent to: ietf-announce-post@cnri.reston.va.us All working group actions shall be taken in a public forum, and wide participation is encouraged. A working group will conduct much of its business via electronic mail distribution lists but may meet periodically to discuss and review task status and progress, to resolve specific issues and to direct future activities. It is common, but not required, that a working group will meet at the trimester IETF Plenary events. Additionally, interim sessions may be scheduled for telephone conference, video teleconference, or for face-to-face (physical) sessions. All working group sessions (including those held outside of the IETF meetings) shall be reported by making minutes available. These minutes should include the agenda for the session, an account of the discussion including any decisions made, and a list of attendees. The Working Group Chair is responsible for insuring that session minutes are written and distributed, though the actual task may be performed by someone designated by the Working Group Chair. The minutes shall be submitted in printable ASCII text for publication in the IETF Proceedings, and for posting in the IETF Directories and are to be sent to: minutes@cnri.reston.va.us3.2. Session venue Each working group will determine the balance of email and face-to- face sessions that is appropriate for achieving its milestones. Electronic mail permits the widest participation; face-to-face meetings often permit better focus and therefore can be more efficient for reaching a consensus among a core of the working group participants. In determining the balance, the WG must ensure that its process does not serve to exclude contribution by email-only participants. Also note that decisions reached during IETF meetings are NOT final, but must be conveyed to the mailing list to verify WG consensus.IETF Meetings If a WG needs a session at an IETF meeting, the Chair must apply for time-slots as soon as the first announcement of that IETF meeting is made by the IETF Secretariat to the WG-chairs list. Session time is a scarce resource at IETF meetings, so placing requests early willHuizer & Crocker [Page 12]
RFC 1603 IETF Working Group Guidelines March 1994 facilitate schedule coordination for WGs requiring the same set of experts. The application for a WG session at an IETF meeting shall be made to the IETF Secretariat. Alternatively some Area Directors may want to coordinate WG sessions in their area and request that time slots be coordinated through them. After receiving all requests for time slots by WGs in the area, the Area Director(s) form a draft session- agenda for their area, which is then sent to the WG chairs of the area. After approval it will be sent to the IETF Secretariat. An application must contain: - The amount of time requested; - The rough outline of the WG agenda that is expected to be covered; - The estimated number of people that will attend the WG session; - Related WGs that must not be scheduled for the same time slot(s); and - Individuals whose attendance is desired. The Secretariat allots time slots on the basis of the session-agenda made by the Area Director(s). If the proposed session- agenda for an area does not fit into the IETF meeting-agenda, the IETF Secretariat will adjust it to fit, after consulting the Area Director(s) and the relevant chairs. The Secretariat will then form a draft session- agenda and distribute it among the Working Group Chairs for final approval. NOTE: While open discussion and contribution is essential to working group success, the Chair is responsible for ensuring forward progress. When acceptable to the WG, the Chair may call for restricted participation (but not restricted attendance!) at IETF working group sessions for the purpose of achieving progress. The Working Group Chair then has the authority to refuse to grant the floor to any individual who is unprepared or otherwise covering inappropriate material.On-line It can be quite useful to conduct email exchanges in the same manner as a face-to-face session, with published schedule and agenda, as well as on-going summarization and consensus polling.Huizer & Crocker [Page 13]
RFC 1603 IETF Working Group Guidelines March 1994 Many working group participants hold that mailing list discussion is the best place to consider and resolve issues and make decisions. Choice of operational style is made by the working group itself. It is important to note, however, that Internet email discussion is possible for a much wider base of interested persons than is attendance at IETF meetings, due to the time and expense required to attend.3.3. Session management Working groups make decisions through a "rough consensus" process. IETF consensus does not require that all participants agree although this is, of course, preferred. In general the dominant view of the working group shall prevail. (However, it must be noted that "dominance" is not to be determined on the basis of volume or persistence, but rather a more general sense of agreement.) Consensus can be determined by balloting, humming, or any other means on which the WG agrees (by rough consensus, of course). The challenge to managing working group sessions is to balance the need for open and fair consideration of the issues against the need to make forward progress. The working group, as a whole, has the final responsibility for striking this balance. The Chair has the responsibility for overseeing the process but may delegate direct process management to a formally-designated Facilitator. It is occasionally appropriate to revisit a topic, to re-evaluate alternatives or to improve the group's understanding of a relevant decision. However, unnecessary repeated discussions on issues can be avoided if the Chair makes sure that the main arguments in the discussion (and the outcome) are summarized and archived after a discussion has come to conclusion. It is also good practice to note important decisions/consensus reached by email in the minutes of the next 'live' session, and to summarize briefly the decision-making history in the final documents the WG produces. To facilitate making forward progress, a Working Group Chair may wish to direct a discussion to reject or defer the input from a member, based upon the following criteria: Old The input pertains to a topic that already has been resolved and is redundant with information previously available;Huizer & Crocker [Page 14]
RFC 1603 IETF Working Group Guidelines March 1994 Minor The input is new and pertains to a topic that has already been resolved, but it is felt to be of minor import to the existing decision; Timing The input pertains to a topic that the working group has not yet opened for discussion; or Scope The input is outside of the scope of the working group charter.3.4. Contention and appeals overview In the course of group design processes, strife happens. Strife and contention are particularly likely when working groups comprise many constituencies. On the other hand differences in view are vital to the success of the IETF and healthy debate is encouraged. Sometimes debates degenerate into something akin to warfare. For these circumstances, the IETF has an extensive review and appeals process. Formal procedures for requesting review and conducting appeals are documented in The Internet Standards Process [1]. A brief summary is provided, here. In fact the IETF approach to reviews and appeals is quite simple: When an IETF participant feels that matters have not been conducted properly, they should state their concern to a member of IETF management. In other words, the process relies upon those who have concerns raising them. If the result is not satisfactory, there are several levels of appeal available, to ensure that review is possible by a number of people uninvolved in the matter in question. Reviews and appeals step through four levels, each in turn: WG Chair An appeal must begin with the management closest to the operation of the working group, even if the concern applies to their own handling of working group process.Huizer & Crocker [Page 15]
RFC 1603 IETF Working Group Guidelines March 1994 Area If discussion and review with the WG Chair do not produce a satisfactory result, the complainant may bring their concern to the cognizant Area Director. IESG If a concerned party is not satisfied with the results of the area-level review, then they may bring the matter to the IESG Chair and the Area Director for Standards & Processes. The IESG Chair and the Standards & Processes AD will bring the issue before the full IESG for an additional review and will report the resolution back to the parties. IAB The IAB provides a final opportunity to appeal the results of previous reviews. If a concerned party does not accept the outcome of the IESG review, then they may take their concern to the IAB, by contacting the IAB Chair. Concerns entail either a disagreement with technical decisions by the working group or with the process by which working group business has been conducted. Technical disagreements may be about specific details or about basic approach. When an issue pertains to preference, it should be resolved within the working group. When a matter pertains to the technical adequacy of a decision, review is encouraged whenever the perceived deficiency is noted. For matters having to do with preference, working group rough consensus will dominate. When a matter pertains to working group process, it is important that those with a concern be clear about the manner in which the process was not open or fair and that they be willing to discuss the issue openly and directly. In turn, the IETF management will make every effort to understand how the process was conducted, what deficiencies were present (if any) and how the matter should be corrected. The IETF functions on the good will and mutual respect of its participants; continued success requires continued attention to working group process.4. WORKING GROUP TERMINATION Working groups are typically chartered to accomplish a specific task. After that task is complete, the group will be disbanded. However if a WG produces a Proposed or Draft Standard, the WG will become dormant rather than disband (i.e., the WG will no longer conductHuizer & Crocker [Page 16]
RFC 1603 IETF Working Group Guidelines March 1994 formal activities, but the mailing list will remain available to review the work as it moves to Draft Standard and Standard status.) If, at some point, it becomes evident that a working group is unable to complete the work outlined in the charter, the group, in consultation with its Area Director can either: 1. Recharter to refocus on a smaller task, 2. Choose new Chair(s), or 3. Disband. If the working group disagrees with the Area Director's choice, it may appeal to the IESG.5. STAFF ROLES Working groups require considerable care and feeding. In addition to general participation, successful working groups benefit from the efforts of participants filling specific functional roles.5.1. WG Chair The Working Group Chair is concerned with making forward progress through a fair and open process, and has wide discretion in the conduct of WG business. The Chair must ensure that a number of tasks are performed, either directly or by others assigned to the tasks. This encompasses at the very least the following: Ensure WG process and content management The Chair has ultimate responsibility for ensuring that a working group achieves forward progress and meets its milestones. For some working groups, this can be accomplished by having the Chair perform all management- related activities. In other working groups -- particularly those with large or divisive participation -- it is helpful to allocate process and/or secretarial functions to other participants. Process management pertains strictly to the style of working group interaction and not to its content. It ensures fairness and detects redundancy. The secretarial function encompasses document editing. It is quite common for a working group to assign the task of specification Editor to one or two participants. Often, they also are part of the design team, described below.Huizer & Crocker [Page 17]
RFC 1603 IETF Working Group Guidelines March 1994 Moderate the WG email list The Chair should attempt to ensure that the discussions on this list are relevant and that they converge to consensus agreements. The Chair should make sure that discussions on the list are summarized and that the outcome is well documented (to avoid repetition). The Chair also may choose to schedule organized on-line "sessions" with agenda and deliverables. These are structured as true meetings, conducted over the course of several days (to allow participation across the Internet.) Participants are expected to allocate time to the meeting, usually in the range of 1-2 hours per day of the "meeting". Organize, prepare and chair face-to-face & on-line formal sessions The Chair should plan and announce sessions well in advance. (See section on Session Planning for exact procedures.) Communicate results of sessions The Chair and/or Secretary must ensure that minutes of a session are taken and that an attendance list is circulated. See the section on Session Documents for detailed procedures. Immediately after a session, the WG Chair must immediately provide the Area Director with a very short report (approximately one paragraph, via email) on the session. This is used in an Area Report as presented in the Proceedings of each IETF meeting. Distribute the work Of course each WG will have participants who may not be able (or want) to do any work at all. Most of the time the bulk of the work is done by a few dedicated participants. It is the task of the Chair to motivate enough experts to allow for a fair distribution of the workload. Document development Working groups produce documents and documents need authors. The Chair will make sure that authors of WG documents incorporate changes as discussed by the WG. See the section on Session Documents for details procedures.Huizer & Crocker [Page 18]
RFC 1603 IETF Working Group Guidelines March 1994 Document publication The Chair and/or Secretary will work with the RFC Editor to ensure document conformance with RFC publication requirements and to coordinate any editorial changes suggested by the RFC Editor. A particular concern is that all participants are working from the same version of a document at the same time.5.2. WG Editor/Secretary Taking minutes and editing working group documents often is performed by a specifically-designated participant or set of participants. In this role, the Editor's job is to record WG decisions, rather than to perform basic specification.5.3. WG Facilitator When meetings tend to become distracted or divisive, it often is helpful to assign the task of "process management" to one participant. Their job is to oversee the nature, rather than the content, of participant interactions. That is, they attend to the style of the discussion and to the schedule of the agenda, rather than making direct technical contributions themselves.5.4. Design teams The majority of the detailed specification effort within a working group may be done by self-selecting sub-groups, called design teams, with the (implicit or explicit) approval of the working group. The team may hold closed sessions for conducting portions of the specification effort. In some cases design teams are necessary to make forward progress when preparing a document. All work conducted by a design team must be available for review by all working group participants and the design team must be responsive to the direction of the working group's consensus.5.5. Area Consultant At the discretion of the AD, a Consultant may be assigned to a working group. Consultants are senior participants in the IETF community. They have technical background appropriate to the WG and experience in Internet architecture and IETF process.Huizer & Crocker [Page 19]
RFC 1603 IETF Working Group Guidelines March 19945.6. Area Director Area Directors are responsible for ensuring that working groups in their area produce coherent, coordinated, architecturally consistent and timely output as a contribution to the overall results of the IETF. This very general description encompasses at the very least these detailed tasks related to working groups: Area planning The Area Director determines activities appropriate to the area. This may include initiating working groups directly, rather than waiting for proposals from IETF participants. Coordination of WGs The Area Director coordinates the work done by the various WGs within (and sometimes even outside) the relevant area. IETF Meeting Schedule The Director tries to coordinate sessions in such a way that experts can attend the relevant sessions with a minimum of overlap and gaps between sessions. (See section on WG sessions for details.) Reporting The Area Director reports to the IETF on progress in the area. Reviewing The Area Director may appoint independent reviewers prior to document approval. The Area Director tracks the progress of documents from the area through the IESG review process, and report back on this to the WG Chair(s). Progress tracking The Area Director tracks and manages the progress of the various WGs with the aid of a regular status report on documents and milestones that is generated by the IESG Secretary. The Area Director forwards this report to the WG chairs. This in turn helps the chairs to manage their WGs.Huizer & Crocker [Page 20]
RFC 1603 IETF Working Group Guidelines March 19945.7. Area Directorate An area directorate consists of senior members of the technical community and are appointed by the Area Director who then tasks them with technical oversight and review of specific area activities. An Area Director chairs the directorate. At the request of the AD, directorate members conduct specification reviews and may be assigned as Area Consultants, to provide architectural assistance.6. WORKING GROUP DOCUMENTS6.1. Session documents All relevant documents for a session (including the final agenda) should be published and available at least two weeks before a session starts. It is strongly suggested that the WG Chair make sure that an anonymous FTP directory be available for the upcoming session. All relevant documents (including the final agenda and the minutes of the last session) should be placed in this directory. This has the advantage that all participants can FTP all files in this directory and thus make sure they have all relevant documents. Also, it will be helpful to provide electronic mail-based retrieval for those documents.6.2. IETF meeting document archive In preparing for an IETF meeting it is helpful to have ready access to all documents that are being reviewed. While documents usually are placed in the internet-drafts Internet Repository or in the respective working group archives or just published in some mail- lists, there are just too many things to browse or read through. Also, many documents are modified immediately before a meeting. The InterNIC Directory and Database Services provides a current- ietf-docs archive to enable people to get all documents that are relevant for the up-coming IETF meeting. This document database will be removed two weeks after the IETF meeting. The completeness of this archive depends on the authors and working group chairs submitting the documents. Each WG Chair is requested to submit the agenda to this archive. Structure of the archive: On ds.internic.net documents will be stored under the appropriate working group name under the appropriate area name in the directory:Huizer & Crocker [Page 21]
RFC 1603 IETF Working Group Guidelines March 1994 /pub/current-ietf-docs Each area will also have a directory called bof where a document to be discussed in a BOF meeting will be placed. At the area level a directory called plenary will be created to hold documents or presentation material related to a plenary session. Any filename conflicts will be resolved by the InterNIC's administrator and the submitter will be informed via electronic mail. Example: /pub/current-ietf-docs/app/osids /pub/current-ietf-docs/int/sip Access via anonymous FTP: Anonymous FTP to ds.internic.net and change directory to /pub/current-ietf-docs/ and browse and get the document of interest. Access via gopher: Connect to gopher.internic.net and select the menu item: 4. InterNIC Directory and Database Services (AT&T)/ and then the menu item: 3. Documents to be reviewed at the *** IETF One may use the public-access gopher client by: telnet gopher.internic.net Submission of documents via anonymous FTP: FTP to ds.internic.net and login as anonymous. Change directory to: /incoming/current-ietf-docs Put the document using the following filename convention, <area>.<wgname>.<filename> e.g.: plenary.mondayVGs.ps app.osids.agenda app.osids.internic-talk-VGs.psHuizer & Crocker [Page 22]
RFC 1603 IETF Working Group Guidelines March 1994 Note that the names of areas and working groups are their official short-form acronyms, Submission of documents via electronic mail: Send mail to admin@ds.internic.net with the following subject line: IETF - <area>.<wgname>.<filename> e.g.: IETF - app.osids.agenda NOTE: Instead of sending a fresh copy of an already available document, you may ask the InterNIC's administrators to create a link to an existing internet-draft/RFC/ID NOTE: If you do not remember your area or working group acronym get the file /ftp/ietf/1wg-summary.txt from ds.internic.net via anonymous FTP.6.3. Internet-Drafts (I-D) The Internet-Drafts directory is provided to working groups as a resource for posting and disseminating early copies of working group documents. This repository is replicated at various locations around the Internet. It is encouraged that draft documents be posted as soon as they become reasonably stable. It is stressed here that Internet-Drafts are working documents and have no official standards status whatsoever. They may, eventually, turn into a standards-track document or they may sink from sight. Internet-Drafts are submitted to: internet-drafts@cnri.reston.va.us The format of an Internet-Draft must be the same as for an RFC [2]. Further, an I-D must contain: - Beginning, standard, boilerplate text which is provided by the Secretariat; - The I-D filename; andHuizer & Crocker [Page 23]
RFC 1603 IETF Working Group Guidelines March 1994 - The expiration date for the I-D. Complete specification of requirements for an Internet-Draft are found in the file: 1id-guidelines.txt in the internet-drafts directory at an Internet Repository site.6.4. Request For Comments (RFC) The work of an IETF working group usually results in publication of one or more documents, as part of the Request For Comments (RFCs) [2] series. This series is the archival publication record for the Internet community. A document can be written by an individual in a working group, by a group as a whole with a designated Editor, or by others not involved with the IETF. The designated author need not be the group Chair(s). NOTE: The RFC series is a publication mechanism only and publication does not determine the IETF status of a document. Status is determined through separate, explicit status labels assigned by the IESG on behalf of the IETF. In other words, the reader is reminded that all Internet Standards are published as RFCs, but NOT all RFCs specify standards. For a description on the various categories of RFCs the reader is referred to [1,4,5,6].6.5. Submission of documents When a WG decides that a document is ready for publication, the following must be done: - The version of the relevant document as approved by the WG must be in the Internet-Drafts directory; - The relevant document must be formatted according to RFC rules [2]. - The WG Chair sends email to the relevant Area Director, with a copy to the IESG Secretary. The mail should contain the reference to the document, and the request that it be progressed as an Informational, Experimental, Prototype or standards-track (Proposed, Draft or Internet Standard) RFC. The IESG Secretary will acknowledge receipt of the email. Unless returned to the WG for further development, progressing of theHuizer & Crocker [Page 24]
RFC 1603 IETF Working Group Guidelines March 1994 document is then the responsibility of the IESG. After IESG approval, responsibility for final disposition is the joint responsibility of the RFC Editor and the WG Chair and Editor.6.6. Review of documents Usually in case of a submission intended as an Informational or Experimental RFC minimal review is necessary. However, if the WG or the RFC Editor thinks that an extensive review is appropriate, the Area Director may be asked to conduct one. This review may either be done by the AD and other IESG participants or the IESG may ask for an independent review (e.g., by someone not part of the WG in question) from the Area Directorate or elsewhere. A review will lead to one of three possible conclusions: 1. The document is accepted as is. This fact will be announced by the IESG Secretary to the IETF mailing list and to the RFC Editor. Publication is then further handled between the RFC Editor and the author(s). 2. Changes regarding content are suggested to the author(s)/WG. Suggestions must be clear and direct, so as to facilitate working group and author correction of the specification. Once the author(s)/WG have made these changes or have explained to the satisfaction of the reviewers why the changes are not necessary, the document will be accepted for publication as under point 1, above. 3. The document is rejected. This will need strong and thorough arguments from the reviewers. The whole IETF and working group process is structured such that this alternative is not likely to arise for documents coming from a working group. After all, the intentions of the document will already have been described in the WG charter, and reviewed at the start of the WG. If any individual or group of individuals feels that the review treatment has been unfair, there is the opportunity to make a procedural complaint. The mechanism for procedural complaints is described in the section on Contention and Appeal. Before the IESG makes a final decision on a standards-track document, the IESG Secretary will issue a "Last Call" to the IETF mailing list. This Last Call will announce the intention of the IESG to considerHuizer & Crocker [Page 25]
RFC 1603 IETF Working Group Guidelines March 1994 the document, and it will solicit final comments from the IETF within a period of two weeks. It is important to note that a Last Call is intended as a brief, final check with the Internet community, to make sure that no important concerns have been missed or misunderstood. The Last Call cannot serve as a more general, in-depth review.7. SECURITY CONSIDERATIONS Security issues are not discussed in this memo.8.

RFC 1603 IETF Working Group Guidelines March 1994APPENDIX: SAMPLE WORKING GROUP CHARTER Multiparty Multimedia Session Control (mmusic) Charter Chair(s): Eve Schooler <schooler@isi.edu> Abel Weinrib <abel@bellcore.com> Transport Area Director(s) Allison Mankin <mankin@cmf.nrl.navy.mil> Mailing lists: General Discussion:confctrl@isi.edu To Subscribe: confctrl-request@isi.edu Archive: venera.isi.edu:~/confctrl/confcrtl.mail Description of Working Group: The demand for Internet teleconferencing has arrived, yet an infrastructure to support this demand is barely in place. Multimedia session control, defined as the management and coordination of multiple sessions and their multiple users in multiple media (e.g., audio, video), is one component of the infrastructure. The Multiparty Multimedia Session Control Working Group is chartered to design and specify a protocol to perform these functions. The protocol will provide negotiation for session membership, underlying communication topology and media configuration. In particular, the protocol will support a user initiating a multimedia multiparty session with other users ("calling" other users) over the Internet by allowing a teleconferencing application on one workstation to explicitly rendezvous with teleconferencing applications running on remote workstations. Defining a standard protocol will enable session-level interoperability between different teleconferencing implementations. The focus of the working group is to design a session negotiation protocol that is tailored to support tightly-controlled conferences. The MBONE currently carries primarily loosely- controlled sessions, i.e., sessions with little to no interaction among members and with no arbitration facility, security, or coordination of quality-of-service options for time-critical media. Users may learn of available sessions using the "sd" utility or other out of band mechanisms (e.g., email). However,Huizer & Crocker [Page 28]
RFC 1603 IETF Working Group Guidelines March 1994 there is clearly also a need for tightly-controlled sessions that provide mechanisms for directly contacting other users to initiate a session and for negotiating conference parameters such as membership, media encodings and encryption keys. In addition, these sessions should support renegotiation during a session, for example to add or delete members or change the media encoding. It is possible that the protocol will, in the limiting case, also support loosely-controlled sessions. The main goal of the working group will be to specify the session control protocol for use within teleconferencing software over the Internet. The working group will focus on the aspects of the session control problem that are well understood, while keeping an eye on evolving research issues. Toward this end, the working group has made an inventory of existing conferencing systems and their session control protocols. The working group will document the requirements of the existing prototypes as a basis for the protocol development. The working group will iteratively refine the protocol based on implementation and operational experience. Furthermore, the working group will coordinate with other efforts related to multimedia conferencing, such as directory services for cataloguing users and conferences, the RTP and RTCP protocols developed by the Audio/Video Transport Working Group, resource reservation and management at the network level, and schemes for multicast address allocation. Goals and Milestones: May 93 Hold an on-line working group meeting to discuss the conference control framework, the relevant terminology, a functional taxonomy and how different conversational styles place requirements on session protocols. Jun 93 Submit the Conference Session Control Protocol to the IESG for consideration as an Experimental Protocol. Aug 93 Post an Internet-Draft describing the Session Control Requirements. Nov 93 Post an Internet-Draft of the Session Control Protocol. Mar 94 Submit a revised Internet-Draft based on implementation experience.Huizer & Crocker [Page 29]
