      <section title="Introduction">
         <!-- Sessions:  f2f, -->

         <t>The <xref target="IETF" /> is an open community of network
            designers, operators, vendors, users, and researchers concerned
            with the development and operation of Internet technical
            specifications. Activities of the IETF are primarily performed by
            committees known as <xref target="WG">Working Groups</xref>. For
            administrative purposes, they are organized into topical <xref
               target="Areas" />. Working groups are formally chartered,
            typically with a narrow focus and lifetime bounded by the
            completion of a specific set of tasks. </t>

         <t>This document describes the formation, requirements, structure,
            and operation of IETF working groups. This includes the formal
            relationships and duties of participants.</t>
         <t>At base, working groups are driven by:<list style="symbols">
               <t>Goals</t>
               <t>Rules</t>
               <t>Tasks</t>
               <t>Participants</t>
            </list> That is, a collection of participants, who fill various
            roles, work toward some common goal(s), according to IETF
            requirements. This document is principally organized according to
            these distinctions.</t>

         <section title="Background">

            <t>This version is organized as an aid to (new) working group
               participants both as an introduction and as a later reference.
                  <list style="symbols">
                  <t>It describes existing IETF rules and practices and does
                     not describe or suggest any changes.</t>
               </list></t>

            <t>Specifically this version of the document: <list
                  style="symbols">
                  <t>Replaces general IETF tutorial material that it had with
                     pointers to independent versions</t>

                  <t>Incorporates work from a number of targeted efforts over
                     the years</t>

                  <t>Reorganizes content to aid direct use by working group
                     participants</t>

                  <t>Distinguishes between formal IETF requirements and
                     processes, versus common practices chosen by working
                     groups, where the latter are primarily discussed in a
                     non-normative <xref target="WG-Advice">external IETF
                        Wiki</xref> that can be continually revised by the
                     community.</t>
               </list></t>

            <t>A useful introduction to the IETF is <xref target="Tao">The Tao
                  of IETF: A Novice's Guide to the Internet Engineering Task
                  Force</xref>. Familiarity with <xref target="RFC2026">The
                  Internet Standards Process</xref> is essential for a

      <section title="Basic Structure and Requirements">
         <t>The IETF permits wide variation in the conduct of working group
            affairs. Still, there is a core of required organization and
            required operation. This section describes that core.</t>
         <section title="Working Group Charter">
            <t>A working group is based on a formal a charter, which is a
               contract between a working group and the IETF to perform a set
               of tasks. A charter: <list style="symbols">
                  <t>Lists relevant administrative information for the working
                     group</t>
                  <t>Specifies the direction or objectives of the working
                     group and describes the approach that will be taken to
                     achieve the goals</t>
                  <t>Enumerates a set of milestones together with time frames
                     for their completion</t>
               </list>Details concerning charters are provided in <xref
                  target="CharterContent" />.</t>
         </section>

         <section title="Deliverables">
            <t>A working group's charter specifies deliverables to be
               achieved. (<xref target="CharterContent" />) These are usually
               documents to be published in the Request for Comments series
                  <xref target="RFC-Editor" />. The means of achieving those
               deliverables is only lightly constrained: whatever permits a
               working group to conduct a fair, open and accountable process,
               while achieving working group rough consensus, is permitted.
               The challenge with this flexibility is formulating the details
               of internal working group structure and process in a manner
               that ensures timely achievement.</t>
            <t>In other words, the group needs to efficiently balance fair and
               open discussion, proper attention to legitimate concerns, and
               making forward progress.</t>
         </section>

         <section anchor="Lists" title="Mailing List">
            <t>A process that is truly open and inclusive makes participation
               as easy as possible, for the widest range of participants as
               possible. For the IETF, that means that the primary venue for
               working group activities MUST be the mailing list associated
               with the group. (<xref target="CharterContent" />) Further, the

               mailing list messages is recorded in the Secretariat's archive
               for the list.</t>
            <t> Multiple versions of list archives are available, as indicated
               in the "Archives" section of <xref target="MailList" />. One

               </figure> where {ACRONYM} is the abbreviated name for the

         <section anchor="AD" title="Area Directors">

            <t>IETF Working Groups are administratively aggregated into
               "areas". Each working group has a designated ("cognizant") Area
               Director [AD] (<xref target="AD-Desc" />,<xref target="Areas"
                />), to formally select chairs for the working group and to
               provide oversight.</t>
         </section>


         <section anchor="Chair" title="Chair(s)">
            <t>Working Group Chairs are formally responsible for ensuring that
               the working group makes forward progress through a fair and
               open process. They have wide discretion in the conduct of WG
               business. However within the bounds of IETF formal requirement,
               Chairs are always accountable to the <xref target="Consensus"
                  >rough consensus</xref> of the working group participants,
               as well as to the Area Director who appointed them. Chairs
               ensure that a number of procedural, administrative and project
               management tasks are performed, either directly or by others
               assigned to the tasks.</t>

            <t>Chairs have the authority and the responsibility to make
               decisions, on behalf of the working group, regarding all
               matters of internal working group process and staffing, in
               conformance with the rules of the IETF. The AD has the
               authority and the responsibility to assist in making those
               decisions at the request of the Chair or when circumstances
               warrant such an intervention.</t>

            <t>The choices for assignment of tasks are highly dependent upon
               the nature of the working group topic, the nature of the work
               to be done, and the nature of working group participation. When
               a topic is well-understood, the deliverables straightforward
               and the participants generally knowledgeable and compatible, a
               very streamlined working group organization can be quite
               reasonable. As topic and/or participation get more challenging,
               working group operation typically needs to be more actively and
               formally managed, typically requiring administrative tasks to
               be spread among other participants and processes for discussion
               and decision-making more structured. </t>

               set of documents, that capture the results of the group's work.
               A working group designates one or more people to serve as the
               Writer for a particular document. The Document Writer is
               responsible for ensuring that the contents of the document
               accurately reflect the decisions that have been made by the
               working group.</t>

            <t>As a general practice, the Working Group Chair and Document
               Writer positions are filled by different individuals to help
               ensure a clear distinction between process management and
               content generation. This helps the resulting documents to
               accurately reflect the consensus of the working group. However
               this separation is not a firm requirement. Especially in a
               small, narrow, simple effort among a cohesive group, it might
               be convenient and efficient for the Chair and Writer roles to
               be combined.</t>

            <t>The Document Writer is variously called an "author" or an
               "editor". The IETF does not have consistent rules for
               distinguishing use of these terms. However, see Section 3 of
                  <xref target="RFC7221" /> for a suggested distinction
               between primary responsibility for creating concepts and
               content, versus responsibility for recording content developed
               by the working group itself. </t>

            <t>The foundation of a working group is its participants. Within
               the scope of the charter, working group participants represent
               the entire Internet, indicating what output is needed from the
               working group effort -- including who will use it and why --
               and providing guidance, ideas, text, discussion, and
               assessment. For all substantive choices, the 'rough consensus'
               of the participants determines the real work of the group.</t>

         <section anchor="Consensus" title="Rough Consensus Decision Making">
            <t>The IETF does not have "members" and it's open processes can
               not make decisions by "voting". Rather, a community sense of
               strongly-dominant agreement, in the absence of compelling
               objections, is used to make decisions. This is called <xref
                  target="RFC7282">Rough Consensus</xref>. Within working
               group processes, this is the required means for making working
               group decisions, but more importantly it is a model for
               considering issues.</t>
            <t><list style="hanging">
                  <t hangText="Expediency:  ">In the abstract, nearly all
                     working group activities and decisions are subject to
                     Rough Consensus. In practice, working group chairs often
                     make decisions based on the assumption of working group
                     support. This practice is essential for working group
                     efficiency, but its risk is that the chair's choices will
                     not actually be in sync with the working group's desires.
                     Consequently, all participants carry the responsibility
                     of voicing concerns they consider significant, even when
                     no other participant has spoken up.</t>
                  <t hangText="Substantiveness:  ">A major challenge in
                     considering Rough Consensus appears to be distinguishing
                     between active and passive support. Active support is
                     indicated by participants that are actively engaged in
                     discussing the topic, whereas passive has, at most, pro
                     forma expressions of support, without any obvious
                     indication that the topic is both understand and
                     important to the participant. The dangers of passive
                     support are that it could mean the topic is not
                     adequately understood and/or that the topic will not
                     obtain community followup, such as deployment and use. </t>
                  <t hangText="Minorities:  ">The other major challenge, as
                     discussed in <xref target="RFC7282" />, is that
                     "minority" concerns are not adequately addressed. In
                     particular in the interest of moving the working group
                     effort along, it is easy to marginalize such concerns
                     because they are expressed by few participants. What this
                     risks is failure to attend to problems that are serious
                     and will affect utility of the work later. There is, of
                     course, a competing pressure that 'minority' voices could
                     stall the working group. So the core working group
                     challenge with a minority concern is to adequately
                     consider its nature and adequately consider its effect,
                     while still making forward progress.</t>

               others are the deliverable product under development. Documents

            <t>Formal adoption of Internet Drafts in a working group is

            <t>The work of an IETF working group typically targets publication
               of one or more documents, as part of the Request For Comments
               (RFC) series. (<xref target="RFC-IETF" />, <xref
                  target="RFC-Editor" />, <xref target="RFC2026" />) This
               series is the archival publication record for the Internet
               community. There are multiple, independent streams that produce
               documents published as RFCs; the IETF stream is one of these. A
               document can be written by an individual in a working group, by
               a group as a whole with a designated Writer, or by others not
               involved with the IETF. The RFC Editor provides guidance for
               writing an RFC. <xref target="RFC7322" /></t>

            <t>NOTE: The RFC series is a publication mechanism only and
               publication does not determine the IETF status of a document.
               RFCs are processed through a number of independent 'streams',
               of which those produced with IETF approval represent one. The
               IETF 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. <xref

               Within those constraints, working groups are nearly autonomous
               and each determines most of the details of its own operation
               with respect to organization, planning, session participation,
               discussion style, means of reaching closure, etc. </t>

               </list></t>
            <t>A number of procedural questions and issues will arise over
               time. The Working Group Chair(s) have ultimate responsibility
               for management of 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.</t>

            <t>There are few hard and fast rules on organizing or conducting
               working group activities, but a set of guidelines and practices
               has evolved over time that have proven successful. Some basic
               choices are listed in (<xref target="Roles" />). These are
               discussed at length in the associated wiki. (<xref

               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 Writer to one or two participants. Sometimes,
               they also are part of the design team, described below. (<xref

               few dedicated participants. It is the task of the Chair to
               motivate enough experts to allow for a fair distribution of the

               <t>A working group requires significant administrative and
                  management work. What is flexible is who performs the work.
                  The choices for assigning one or more tasks to a participant
                  filling a particular role will depend upon the assessment of
                  the Chair(s). For example, as the scale or complexity or
                  contentiousness of a working group increases, so does its
                  risk of failure and its attendant need for more active and
                  more formal management. </t>
               <t>This typically means stricter adherence to formal rules of
                  working group process and assignment of various tasks to a
                  wider set of participants in specific roles, so that each
                  task receiver proper focus. Roles that are required or, at
                  least, useful are discussed later, in (<xref target="Roles"

               against the need to make forward progress. The working group,
               as a whole, has the final responsibility for striking this

         <section title="IETF Open Decision-Making">
            <t>The IETF values and demands open, inclusive decision-making by
               working groups. A process that is truly open and inclusive
               makes participation as easy as possible, for the widest range
               of participants as possible. <list>
                  <t>For the IETF, that means that the official venue for
                     working group formal decision-making MUST be the mailing
                     list associated with the group AND NOWHERE ELSE. </t>
               </list></t>

            <t>Working groups make decisions through a <xref
                  target="Consensus">"rough consensus" process</xref>, which
               entails considerably more than merely determining that a
               majority are for or against a particular choice. IETF rough
               consensus does not require that all participants agree although
               this is, of course, preferred. In general, the dominant view of
               the working group needs to prevail, absent compelling arguments
               against. In particular note the role of "minority" views, as
               discussed in <xref target="RFC7282" />.</t>
            <t>It can be especially challenging to gauge the level of
               consensus on a mailing list. There are two different cases
               where a working group might be trying to understand the level
               of consensus via a mailing list discussion. But in both cases
               the volume of messages on a topic is not, by itself, a good
               indicator of consensus since one or two individuals might be
               generating much of the traffic. </t>

         <section title="Mailing List Primacy">

            <t>Discussions relating to working group topics MAY happen
               anywhere, amongst any group of people, on a spontaneous or
               continuing basis and as a closed or open set. Closed groups
               that persist with a continuing role in providing substantive
               input to the working group's content are called 'design teams'.
               They can be self-forming or created by the Chair(s).</t>

            <t>The working group, itself, can provide a variety of open
               discussion venues, over the life of the working group, as
               discussed below. However discussions are conducted, "decisions"
               made at venues other than the working group mailing list MUST
               be treated as preliminary, and MUST be explicitly documented
               and confirmed through the mailing list.</t>

            <t>An example method is to post a note summarizing: <list
                  style="symbols">
                  <t>the discussion</t>

                  <t> the proposed resolution</t>

                  <t> the rationale for proposing its adoption</t>
               </list></t>

            <t>This provides working group participants with enough
               foundational material to understand the proposal and comment on
               it or even support it. It also creates a record on the official
               email archive.</t>

            <t>If discussion is held entirely over the mailing list,
               determination of the level of consensus might be harder to do,
               since most people subscribed to mailing lists do not actively
               participate in discussions. It is left to the discretion of the
               working group chair how to evaluate the level of consensus. The
               most common method used is for the working group chair to state
               what they believe to be the consensus view and at the same
               time, request comments from the list about the stated
               conclusion.</t>

            <t>Each working group will determine the balance of email versus

               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. <list style="hanging">

            <section title="Tradeoffs">

               <t>Each working group will determine the balance of email
                  versus interactive (face-to-face, online, ...) sessions that
                  is appropriate for achieving its milestones. The choices are
                  affected by various factors, including the working group's
                  milestone schedule -- that is, degree of urgency --
                  complexity of the work, number of active discussants, and
                  the schedule and support of those discussants.</t>

               <t>However there tends to be a significant tradeoff between
                  doing work at interactive sessions, versus working group
                  inclusiveness.</t>

               <t>Interactive sessions demand that a participant's schedule
                  permit availability during the sessions. Even when held
                  online, this can be a significant burden for some
                  participants. Even if their formal schedule is sufficiently
                  flexible, the fact of different participant timezones tends
                  to work to the disadvantage of some participants.</t>

               <t>If the meetings are face-to-face, the schedule and monetary
                  demands are dramatically higher and, obviously, further
                  restrict participation.</t>

               <t>A mailing list venue permits the widest and most-convenient
                  participation, by allowing for time-shifted debate among
                  participants in multiple time zones. Its asynchrony also
                  permits the most thoughtful presentation of views and the
                  most thoughtful consideration of them.</t>

               <t>Interactive, real-time meetings often provide richer and
                  higher speed communication with lower latency and therefore
                  permit better focus. They therefore can be more efficient
                  for reaching a consensus among a core of the working group
                  participants, especially for narrow and contested
                  choices.</t>

               <t>Any tools that permit real-time, or time-shifted,
                  interaction and information exchange could be used, without
                  affecting the basic principle that decisions are exposed and
                  confirmed on the mailing list -- Facebook, Twitter, github,
                  issue tracker, etc. Note that these do not provide a formal,
                  IETF archive of the activity, although their record can be
                  useful to cite.</t>

               <t><list>
                     <t>The mode of interaction can (and probably ought) be
                        different in different situations. Regardless, the
                        choice of operational style MUST be made through rough
                        consensus of all working group mailing list
                        participants. In determining the balance, the working
                        group MUST ensure that its process does not serve to
                        exclude substantive contribution by email-only
                        participants.</t>
                  </list></t>

               <t>A basic principle is that although face-to-face discussion,
                  either during a plenary week or at an interim meeting, might
                  sometimes be considered essential to make rapid progress or
                  to resolve tricky issues, this MUST NOT be discriminatory
                  against those unable to attend. As far as technically and
                  financially possible, facilities for passive and active
                  remote participation SHOULD be provided.</t>

               <t>Similarly, "virtual" interim meetings in which all
                  participants are remote MUST NOT be discriminatory against
                  those unable to attend.</t>
               <t><list>
                     <t>The choice of operational style MUST be made by the
                        working group itself.</t>

                     <t>Again: consensus reached during an interactive session
                        is purely preliminary. The proposed decision and its
                        basis MUST be reviewed on the mailing list, and rough
                        consensus developed and documented there.</t>

               <t>It can be quite useful to conduct email exchanges in the

                  consensus polling, even though message-posting and

            working group can absorb, or becoming adversarial with working
            group preferences. An especially conducive environment for this
            problem combines original (pre-working group) authors with a more
            passive working group. However a working group that does not fully
            and actively support a specification, the greater the risk that it

         <section title="Early Document Review">
            <t>It is easier to make substantial changes to a specification
               during its early stages than it is later on. Periodically, the
               IETF's various late-stage reviews uncover basic concerns with
               assumptions or approaches in a design. When a working group is
               pursuing a solution that has unusual design choices or unusual
               operational characteristics, or has any other feature that
               might impede its success, or when the working group
               participants have less experience in producing specifications
               for Internet-scale use, it is advisable to recruit review and
               advice from a broad base of experts.</t>
         </section>

         <section anchor="CrossDoc"
            title="Document Coordination Between Working Groups">
            <t>A document is adopted by one working group as a deliverable;
               they are therefore responsible for its development, review and
               publication. (<xref target="WG-ID" />) When initiated outside a
               working group environment, the writer(s) usually have a
               specific -- possibly new -- working group in mind as the
               development home. However some documents address problems or
               contain technologies that span multiple Areas or working
               groups. In such cases, the document is assigned to one of
               these, with other interested groups participating in the
               development process. This joint participation can take many
               forms. One example is a joint Working Group Last Call conducted
               by the host group but announced on the mailing lists for the
               other interested groups.</t>
            <t>As an example, documents that extend DHCP to carry
               configuration information for other protocols often span
               multiple working groups. Some of these documents define a
               simple DHCP option that follows one of the option formats in
               section 5 of <xref target="RFC7227" />. Such options can be
               developed in the working group responsible for the protocol
               that will use the option, without significant participation of
               the dhc working group. A joint last call between the two groups
               might be all that is required. However some documents will
               define options that have a significantly new option format, or
               define a new DHCP message or otherwise make a fundamental
               change to the semantics of DHCP message exchanges. These
               options or new messages will be developed in the dhc working
               group, with input from other interested groups, to ensure that
               there are no conflicts or other issues with the documents that
               would cause problems with the DHCP standards. </t>
         </section>

         <section title="Working Group Last-Call">
            <t> When a WG decides that a document is ready for publication it
               is submitted to the IESG for consideration. In most cases the
               determination that a WG feels that a document is ready for
               publication is done by the WG Chair issuing a working group
               Last- Call. The decision to issue a working group Last-Call is
               at the discretion of the WG Chair working with the Area
               Director. A working group Last-Call serves the same purpose
               within a working group that an IESG Last-Call does in the
               broader IETF community. (<xref target="RFC2026" />)</t>

         <section title="Final External Review of Documents">

            <t> The IESG reviews all documents submitted for publication as
               RFCs. Usually minimal IESG review is necessary in the case of a
               submission from a WG intended as an Informational or
               Experimental RFC. More extensive review is undertaken in the
               case of standards-track documents.</t>

            <t>Prior to the IESG beginning their deliberations on
               standards-track documents, IETF Secretariat will issue a
               "Last-Call" to the IETF mailing list. (<xref target="RFC2026"
                />) This Last Call will announce the intention of the IESG to
               consider 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 should not
               serve as a more general, in-depth review.</t>

            <t>The IESG review takes into account responses to the Last-Call
               and will lead to one of these possible conclusions: <list
                  style="numbers">
                  <t>The document is accepted as is for the status requested.
                     This fact will be announced by the IETF Secretariat to
                     the IETF mailing list and to the RFC Editor.</t>
                  <t>The document is accepted as-is but not for the status
                     requested. This fact will be announced by the IETF
                     Secretariat to the IETF mailing list and to the RFC
                     Editor. (See <xref target="RFC2026" /> for more
                     details.)</t>
                  <t>Changes regarding content are suggested to the
                     Writer(s)/WG. Suggestions from the IESG need to be clear
                     and direct, so as to facilitate working group and Writer
                     correction of the specification. If the Writer(s)/WG can
                     explain to the satisfaction of the IESG why the changes
                     are not necessary, the document will be accepted for
                     publication as under point 1, above. If the changes are
                     made the revised document MAY be resubmitted for IESG
                     review.</t>
                  <t>Changes are suggested by the IESG and a change in status
                     is recommended. The process described above for 3 and 2
                     are followed in that order.</t>
                  <t>The document is rejected. Any document rejection will be
                     accompanied by specific and thorough arguments from the
                     IESG. Although the IETF and working group process is
                     structured such that this alternative is not likely to
                     arise for documents coming from a working group, the IESG
                     has the right and responsibility to reject documents that
                     the IESG feels are fatally flawed in some way.</t>
               </list></t>

            <t>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 this type of complaints
               is described in <xref target="RFC2026" />.</t>

      <section anchor="Roles" title="Staff Roles">

         <t>From initial chartering, through document development and
            publication, ending with working group termination, there are
            tasks that are formally required to be done, while others are
            merely -- though often very -- helpful to do. This document
            discusses the formal tasks and many of the other, useful
            tasks.</t>

         <t>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. </t>

         <t> Beyond a limited set of formal tasks, there are no rules about
            who MAY be assigned tasks internal to the working group. This
            section discusses possible mappings between working group tasks
            and working group participants who might be assigned roles for
            performing those tasks. However it is important to remember that
            such mappings are strictly at the discretion of the chairs,
            assuming working group agreement.</t>

                     order for a design team to remain small and agile, it is
                     acceptable to have closed membership and private

            <t>IETF working groups (WGs) are the primary means of developing
               IETF specifications and guidelines, many of which are intended
               to be standards or recommendations. Working groups are
               typically created to address a specific problem or to produce
               one or more specific deliverables (a guideline, standards
               specification, etc.). Working groups are generally expected to
               be short-lived in nature. </t>

            <t>A working group is typically created by a community initiative,
               but can also be established at the initiative of an Area
               Director. Anyone interested in creating an IETF working group
               MUST obtain the advice and consent of IETF Area Director(s) and
               MUST proceed through the formal steps detailed in this
               section.</t>



            <section anchor="FormCriteria" title="Criteria for formation">

               <t>When determining whether it is appropriate to create a
                  working group, the Area Director(s) and the IESG will
                  consider several issues: <list style="hanging">
                     <t hangText="Issues:  ">Are the issues that the working
                        group plans to address clear and relevant to the
                        Internet community? </t>
                     <t hangText="Goals:  ">Are the goals specific and
                        reasonably achievable, and achievable within a

                     <t hangText="Risks/Urgency:  ">What are the risks and
                        urgency of the work, to determine the level of effort

                     <t hangText="WG Overlap:  ">Do the working group's
                        activities overlap with those of another working
                        group? If so, it can still be appropriate to create
                        the working group, but this question needs to be
                        considered carefully by the Area Directors as
                        subdividing efforts often dilutes the available
                        technical expertise. </t>
                     <t hangText="Interest:  ">Is there sufficient interest
                        within the IETF in the working group's topic with
                        enough 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 contributing to the
                        document text. IETF experience suggests that these
                        roles typically cannot all be handled by one person; a
                        minimum of four or five active participants in the
                        management positions are typically required in
                        addition to a minimum of one or two dozen people that
                        will attend the working group meetings and contribute
                        on the mailing list. NOTE: The interest needs to be
                        broad enough that a working group would not be seen as
                        merely the activity of a single vendor.</t>
                     <t hangText="Expertise:  ">Is there enough expertise
                        within the IETF in the working group's topic, and are
                        those people interested in contributing in the working
                        group? </t>

                        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. </t>

                        reasonable role to play in the determination of the

                        technologies that might be interesting to IETF
                        participants but in some cases the IETF might not be
                        in a position to effect the course of the technology
                        in the "real world". This can happen, for example, if
                        the technology is being developed by another standards
                        body or an industry consortium. </t>

            <section anchor="BOF" title="Birds of a Feather (BOF)">

               <t>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 (<xref target="RFC5434" />) as well as the
                  early formation of an email list for preliminary discussion.
                  In addition, a BOF can serve as a forum for a single
                  presentation or discussion, without any intent to form a
                  working group.</t>

               <t> 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 a relevant Area Director, and their
                  approval MUST be obtained before a BOF can be scheduled. The
                  person who requests the BOF MAY be asked to serve as Chair
                  of the BOF.</t>

               <t>The Chair of the BOF is also responsible for providing a
                  report on the outcome of the BOF. If the Area Director
                  approves, the BOF is then scheduled by submitting a request
                  to agenda@ietf.org with copies to the Area Director(s). A
                  BOF description and agenda are required before a BOF can be
                  scheduled.</t>

               <t>Available time for BOFs is limited, and BOFs are held at the
                  discretion of the ADs for an area. The AD(s) MAY require
                  additional assurances before authorizing a BOF. For example,
                     <list style="symbols">
                     <t>The Area Director MAY require the establishment of an
                        open email list 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. </t>
                     <t>The Area Director MAY require that there be a draft of
                        the WG charter prior to holding a BOF. </t>
                     <t>The Area Director MAY require that a BOF not be held
                        until an Internet-Draft describing the proposed
                        technology has been issued so it can be used as a
                        basis for discussion in the BOF.</t>
                  </list></t>

               <t>In general, a BOF on a particular topic is held only once --
                  ONE slot at one IETF Plenary meeting. Under unusual
                  circumstances Area Directors MAY, at their discretion, allow
                  a BOF to meet for a second time. BOFs are limited to a
                  maximum of two meetings. Note that all other things being
                  equal, WGs will be given priority for meeting space over
                  BOFs. Also, occasionally BOFs might be held for other
                  purposes than to discuss formation of a working group. </t>
               <t>Usually the outcome of a BOF will be one of the following:

            <section anchor="CharterDev" title="Charter Development">
               <t>The formation of a working group requires a charter.
                  Development of a charter results from the efforts of
                  interested parties and an Area Director. The substance of
                  IETF working group charters is specified in <xref
                     target="CharterContent" />. The development of the
                  proposed charter is overseen by a shepherding Area Director
                  and can be pursued in a number of ways.</t>

               <t> The method of developing a charter can vary greatly. In
                  many instances, the development of the charter is carried
                  out on an open mailing list, allowing all interested IETF
                  participants to contribute to the effort. Among other
                  possibilities, charter development might driven by a small
                  group of active proponents. All charter development models
                  allow for interested participants to take ownership in the
                  purpose and outcome of the working group.</t>

               <t> It is common, but not required, to hold an exploratory
                  Birds of a Feather (BOF) meeting to gauge the level of
                  support for a working group.(<xref target="RFC5434" />,<xref
                     target="BOF" />) Such a BOF can focus on formulating the
                  problem to be solved, considering the key items in a
                  proposed charter, discussing proposed solutions, or some
                  combination of these items.</t>

               <t> When the prospective Chair(s), the Area Director and the
                  IETF Secretariat are satisfied with the charter form and
                  content, it becomes the foundation of the working group
                  approval process and for the substantive conduct of the
                  working group.</t>

               <t>Proposed working groups often include 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. <list style="hanging">

               working group MAY also be terminated for other reasons, as

            <t>If there is sufficient community interest the working group
               will formally become dormant rather than be disbanded -- the WG
               will no longer conduct formal activities -- so that the mailing

            <t>Disputes are possible at various stages during the IETF

               however, there are times when even the most reasonable and
               knowledgeable people are unable to agree. To achieve the goals
               of openness and fairness, resolution of such conflicts MUST be

                  <t> In many standards track documents several words are used
                     to signify the requirements in the specification. These
                     words are often capitalized. This document defines these
                     words as they should be interpreted in IETF documents.
                     Authors who follow these guidelines should incorporate
                     this phrase near the beginning of their document: <list>
                        <t> The key words "MUST", "MUST NOT", "REQUIRED",
                           "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT",
                           "RECOMMENDED", "MAY", and "OPTIONAL" in this
                           document are to be interpreted as described in RFC
                           2119. </t>

                  <t> Note that the force of these words is modified by the
                     requirement level of the document in which they are used.

                     When a working group is ready to develop a particular
                     document, the most common mechanism is for it to "adopt"
                     an existing document as a starting point. The document
                     that a working group adopts and then develops further is
                     based on initial input at varying levels of maturity. An
                     initial working group draft might be a document already
                     in wide use, or it might be a blank sheet, wholly created
                     by the working group, or it might represent any level of
                     maturity in between. This document discusses how a

               <abstract>
                  <t>The IETF has had a long tradition of doing its technical
                     work through a consensus process, taking into account the
                     different views among IETF participants and coming to (at
                     least rough) consensus on technical matters. In
                     particular, the IETF is supposed not to be run by a
                     "majority rule" philosophy. This is why we engage in
                     rituals like "humming" instead of voting. However, more
                     and more of our actions are now indistinguishable from
                     voting, and quite often we are letting the majority win
                     the day without consideration of minority concerns. This
                     document explains some features of rough consensus, what
                     is not rough consensus, how we have gotten away from it,
                     how we might think about it differently, and the things
                     we can do in order to really achieve rough
                     consensus.</t><t> Note: This document is quite
                     consciously being put forward as Informational. It does
                     not propose to change any IETF processes and is therefore
                     not a BCP. It is simply a collection of principles,
                     hopefully around which the IETF can come to (at least
                     rough) consensus.</t>

Charter for Working Group

The DNS PRIVate Exchange (DPRIVE) Working Group develops mechanisms to
provide confidentiality to DNS transactions, to address concerns
surrounding pervasive monitoring (RFC 7258).

The set of DNS requests that an individual makes can provide an
attacker with a large amount of information about that individual.
DPRIVE aims to deprive the attacker of this information. (The IETF
defines pervasive monitoring as an attack [RFC7258])

The primary focus of this Working Group is to develop mechanisms that
provide confidentiality between DNS Clients and Iterative Resolvers,
but it may also later consider mechanisms that provide confidentiality
between Iterative Resolvers and Authoritative Servers, or provide
end-to-end confidentiality of DNS transactions. Some of the results of
this working group may be experimental. The Working Group will also
develop an evaluation document to provide methods for measuring the
performance against pervasive monitoring; and how well the goal is met.
The Working Group will also develop a document providing example
assessments for common use cases.

DPRIVE is chartered to work on mechanisms that add confidentiality to
the DNS. While it may be tempting to solve other DNS issues while
adding confidentiality, DPRIVE is not the working group to do this.
DPRIVE will not work on any integrity-only mechanisms.

Examples of the sorts of risks that DPRIVE will address can be found
in [draft-bortzmeyer-dnsop-dns-privacy], and include both passive
wiretapping and more active attacks, such as MITM attacks. DPRIVE will
address risks to end-users' privacy (for example, which websites an
end user is accessing).

Some of the main design goals (in no particular order) are:

- Provide confidentiality to DNS transactions (for the querier).

- Maintain backwards compatibility with legacy DNS implementations.

- Require minimal application-level changes.

- Require minimal additional configuration or effort from applications or users

Description of Working Group:

 Before Internet telephony can become a widely deployed service, a
 number of protocols must be deployed. These include signaling and
 capabilities exchange, but also include a number of "peripheral"
 protocols for providing related services.

 The primary purpose of this working group is to develop two such
 supportive protocols and a frameword document. They are:

 1. Call Processing Syntax. When a call is setup between two
 endpoints, the signaling will generally pass through several servers
 (such as an H.323 gatekeeper) which are responsible for forwarding,
 redirecting, or proxying the signaling messages. For example, a user
 may make a call to j.doe@bigcompany.com. The signaling message to
 initiate the call will arrive at some server at bigcompany. This
 server can inform the caller that the callee is busy, forward the
 call initiation request to another server closer to the user, or drop
 the call completely (among other possibilities). It is very desirable
 to allow the callee to provide input to this process, guiding the
 server in its decision on how to act. This can enable a wide variety
 of advanced personal mobility and call agent services.
 Such preferences can be expressed in a call processing syntax, which
 can be authored by the user (or generated automatically by some
 tool), and then uploaded to the server. The group will develop this
 syntax, and specify means of securely transporting and extending it.
 The result will be a single standards track RFC.

 2. In addition, the group will write a service model document, which
 describes the services that are enabled by the call processing
 syntax, and discusses how the syntax can be used. This document will
 result in a single RFC.

 3. Gateway Attribute Distribution Protocol. When making a call
 between an IP host and a PSTN user, a telephony gateway must be used.
 The selection of such gateways can be based on many criteria,
 including client expressed preferences, service provider preferences,
 and availability of gateways, in addition to destination telephone
 number.  Since gateways outside of the hosts' administrative domain
 might be used, a protocol is required to allow gateways in remote
 domains to distribute their attributes (such as PSTN connectivity,
 supported codecs, etc.) to entities in other domains which must make
 a selection of a gateway. The protocol must allow for scalable,
 bandwidth efficient, and very secure transmission of these
 attributes. The group will investigate and design a protocol for this
 purpose, generate an Internet Draft, and advance it to RFC as
 appropriate.

Goals and Milestones:
 
 May 98 Issue first Internet-Draft on service framework
 Jul 98 Submit framework ID to IESG for publication as an RFC.
 Aug 98 Issue first Internet-Draft on Call Processing Syntax
 Oct 98 Submit Call processing syntax to IESG for consideration
     as a Proposed Standard.
 Dec 98 Achieve consensus on basics of gateway attribute
        distribution protocol
 Jan 99 Submit Gateway Attribute Distribution protocol to IESG
        for consideration as a RFC (info, exp, stds track TB

Charter for Working Group

Low power and Lossy networks (LLNs) are made up of many
embedded devices with limited power, memory, and processing
resources. They are interconnected by a variety of links, such as
IEEE 802.15.4, Bluetooth, Low Power WiFi, wired or other low
power PLC (Powerline Communication) links. LLNs are transitioning
to an end-to-end IP-based solution to avoid the problem of
non-interoperable networks interconnected by protocol translation
gateways and proxies.

Generally speaking, LLNs have at least five distinguishing
characteristics:
- LLNs operate with a hard, very small bound on state.
- In most cases, LLN optimize for saving energy.
- Typical traffic patterns are not simply unicast flows (e.g. in some
  cases most if not all traffic can be point to multipoint)
- In most cases, LLNs will be employed over link layers with
  restricted frame-sizes, thus a routing protocol for LLNs should be
  specifically adapted for such link layers.
- LLN routing protocols have to be very careful when trading off
  efficiency for generality; many LLN nodes do not have resources to
  waste.

These specific properties cause LLNs to have specific routing
requirements.

Existing routing protocols such as OSPF, IS-IS, AODV, and OLSR have
been evaluated by the working group and have in their current form been
found to not satisfy all of these specific routing requirements.

The Working Group is focused on routing issues for LLN.

There is a wide scope of application areas for LLNs, including
industrial monitoring, building automation (HVAC, lighting, access
control,
fire), connected homes, healthcare, environmental monitoring, urban sensor
networks (e.g. Smart Grid), asset tracking. The Working Group focuses
on routing solutions for a subset of these: industrial, connected
home, building and urban sensor networks for which routing requirements have
been specified. These application-specific routing requirement
documents will be used for protocol design.

The Working Group focuses only on IPv6 routing architectural framework
for these application scenarios. The Framework will take into
consideration various aspects including high reliability in the presence
of time
varying loss characteristics and connectivity while permitting low-power
operation with very modest memory and CPU pressure in networks
potentially comprising
a very large number (several thousands) of nodes.

The Working Group will pay particular attention to routing security
and manageability (e.g., self routing configuration) issues. It will
also need to consider the transport characteristic the routing protocol
messages will experience. Mechanisms that protect an LLN from congestion
collapse or
that establish some degree of fairness between concurrent
communication sessions are out of scope of the Working Group. It is
expected that
upper-layer applications utilizing LLNs define appropriate mechanisms.
The solution must include unicast and multicast considerations.

Work Items:

- Specification of routing metrics used in path calculation. This
includes static and dynamic link/node attributes required for routing in
LLNs.

- Provide an architectural framework for routing and path selection at
Layer 3 (Routing for LLN Architecture) that addresses such issues as
whether LLN routing require a distributed and/or centralized path
computation models, whether additional hierarchy is necessary and how it
is
applied.

Manageability will be considered with each approach, along with
various trade-offs for maintaining low power operation, including the
presence of non-trivial loss and networks with a very large number of nodes.
should
- Produce a routing security framework for routing in LLNs.

- Protocol work: The Working Group will consider specific routing
requirements from the four application documents collectively, and
specify either
a new protocol or extend an existing routing protocol in cooperation
with the
relevant Working Group.
If requirements from the four target application areas cannot be met
with a single protocol, the WG may choose to specify or extend more than
one
protocol (this will require a recharter of the WG).

- Documentation of applicability statement of ROLL routing protocols.

                  <t>Some WGs do work that requires interaction and
                     cooperation with other standards bodies. WG
                     administrative staff should be aware of the possibility
                     of such interactions, as formally described regarding
                     IEEE in RFC 7241 and ITU-T in RFC 6756. The IETF has
                     established a formal liaison role for some of these
                     interactions, as defined in RFC 4691. RFC 4929 describes
                     a specific (and historically interesting) example of
                     interaction between the IETF and ITU-T.</t>
                  <t> Handling Internet-Drafts as part of the activities of
                     Working Groups is summarized in RFC 2418bis and described
                     in detail in RFC 7241. The states that a WG document can
                     take are defined in RFC 6174.</t>
                  <t> The co-chairs are responsible for behavior of WG
                     participants as part of the IETF. RFC 7154 can help to
                     identify and deal with unacceptable behavior.</t>
                  <t> Intellectual property rights (IPR) management is crucial
                     to the IETF and has been the source of serious legal
                     issues in the past. Read RFC 6702 to understand the IETF
                     disclosure rules and how to make sure your WG stays in
                     compliance with those rules. Also read RFC 6701 to learn
                     how you can deal with IPR policy violations.</t>
