Internet-Draft RFC 2026 practice July 2008
1. Introduction
BCP 9 [RFC2026] has been the basis for the IETF standards process for
many years. This document is a review of how some aspects of the
process work in practice. The focus is mainly on how the community,
and the IESG in particular, interprets the formal rules in actual
practice. It is intended as a purely descriptive document and in no
way claims to change the formal rules.
Newcomers to the IETF should first read the Tao of the IETF
[RFC4677]. For a living guide to all IETF process documents, see
<http://www.ietf.org/IESG/content/procdocs.html>. While this
document mainly focuses on RFC 2026, many other documents form part
of the IETF rules.
Extracts from RFC 2026 are presented verbatim in quotation marks,
preceded and followed by the following markers:

Original pagination and administrative material have been ignored,
but the original section headings have been included where
convenient.
2. Detailed Commentary
"---------Begin Extract---------
1.1 Internet Standards
...
The Internet Standards Process described in this document is
concerned with all protocols, procedures, and conventions that are
used in or by the Internet, whether or not they are part of the
TCP/IP protocol suite. In the case of protocols developed and/or
standardized by non-Internet organizations, however, the Internet
Standards Process normally applies to the application of the protocol
or procedure in the Internet context, not to the specification of the
protocol itself.
-----------End Extract---------"
In practice, things are not as easily delimited as the above
paragraph suggests. Some IETF standards are quite interwoven with
standards from other organizations. Hence, liaison relationships
have become complex and important, dealing with mutually
interdependent standards.

Internet-Draft RFC 2026 practice July 2008
"---------Begin Extract---------
1.2 The Internet Standards Process
...
o These procedures are explicitly aimed at recognizing and adopting
generally-accepted practices. Thus, a candidate specification
must be 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.
-----------End Extract---------"
It is a fact that relatively few standards advance beyond the
Proposed Standard stage, and hence the mechanisms for documenting
interoperability are often not used.
"---------Begin Extract---------
2.1 Requests for Comments (RFCs)
...
The RFC series of documents on networking began in 1969 as part of
the original ARPA wide-area networking (ARPANET) project (see
Appendix A for glossary of acronyms). RFCs cover a wide range of
topics in addition to Internet Standards, from early discussion of
new research concepts to status memos about the Internet. RFC
publication is the direct responsibility of the RFC Editor, under the
general direction of the IAB.
-----------End Extract---------"
There is a general description in [RFC4844]. Today, the RFC Editor's
work for the IETF is also under the administrative management of the
IASA [RFC4071].
"---------Begin Extract---------
The rules for formatting and submitting an RFC are defined in [5].

Note that [I-D.rfc-editor-rfc2223bis] is applied today.

Carpenter Expires January 3, 2009 [Page 4]
Internet-Draft RFC 2026 practice July 2008
The status of Internet protocol and service specifications is
summarized periodically in an RFC entitled "Internet Official
Protocol Standards" [1]. This RFC shows the level of maturity and
other helpful information for each Internet protocol or service
specification (see section 3).
-----------End Extract---------"
This was written before a hyperlinked index was available on line.
In recent years, this RFC has been updated very rarely.
"---------Begin Extract---------
Some RFCs document Internet Standards. These RFCs form the 'STD'
subseries of the RFC series [4]. When a specification has been
adopted as an Internet Standard, it is given the additional label
"STDxxx", but it keeps its RFC number and its place in the RFC
series. (see section 4.1.3)
-----------End Extract---------"
Note that sometimes users do not readily know where to look for the
latest standard, since a DS may obsolete an STD, and a PS may
obsolete either. This is documented in the official RFC index and at
<http://www.rfc-editor.org/categories/rfc-standard.html>, but is
obscured at <http://www.rfc-editor.org/rfcxx00.html>, where obsoleted
standards are not identified.
"---------Begin Extract---------
Some RFCs standardize the results of community deliberations about
statements of principle or conclusions about what is the best way to
perform some operations or IETF process function. These RFCs form
the specification has been adopted as a BCP, it is given the
additional label "BCPxxx", but it keeps its RFC number and its place
in the RFC series. (see section 5)
Not all specifications of protocols or services for the Internet
should or will become Internet Standards or BCPs. Such non-standards
track specifications are not subject to the rules for Internet
standardization. Non-standards track specifications may be published
directly as "Experimental" or "Informational" RFCs at the discretion
of the RFC Editor in consultation with the IESG (see section 4.2).
-----------End Extract---------"
Factually, the RFC Editor does not have such discretion for IETF
documents - it's the IESG approval that defines the status of an IETF
Carpenter Expires January 3, 2009 [Page 5]
Internet-Draft RFC 2026 practice July 2008
RFC. IETF Experimental or Informational RFCs (see
<http://www.ietf.org/IESG/STATEMENTS/ad-sponsoring.html>) are
distinct from independent submissions to the RFC Editor (see
[RFC4846]), which are processed under [RFC3932].
"---------Begin Extract---------
2.2 Internet-Drafts
During the development of a specification, draft versions of the
document are made available for informal review and comment by
placing them in the IETF's "Internet-Drafts" directory, which is
replicated on a number of Internet hosts. This makes an evolving
working document readily available to a wide audience, facilitating
the process of review and revision.
An Internet-Draft that is published as an RFC, or that has remained
unchanged in the Internet-Drafts directory for more than six months
without being recommended by the IESG for publication as an RFC, is
...
-----------End Extract---------"
This is inaccurate. Expiry is inhibited when a draft enters IESG
consideration, not when it is approved.
"---------Begin Extract---------
...
simply removed from the Internet-Drafts directory.
-----------End Extract---------"
In practice today,
1. Drafts are also removed from the directory after publication as
an RFC.
2. All drafts are retained in the IETF archive for legal reasons,
such as for demonstrating claims of prior art.
3. Expired drafts are unofficially visible in many places.
4. Authors may request expired drafts to be removed from such
visibility (in some countries, this is a legal right).
It's also worth noting that the published RFC will not be textually
identical to the final version of the draft. Not only will the
boilerplate be finalized; the RFC Editor will also make editorial
corrections, and any minor technical changes following IESG review
will be applied.

Internet-Draft RFC 2026 practice July 2008
"---------Begin Extract---------
3.1 Technical Specification (TS)
A Technical Specification is any description of a protocol, service,
procedure, convention, or format.
-----------End Extract---------"
This has not been interpreted to limit a TS to defining a wire
protocol - it doesn't exclude APIs, for example (an API is a
convention), even though the IETF tends to avoid standardizing APIs.
It includes data definitions such as MIBs (a MIB is clearly a
format). It doesn't exclude a standard that only defines an IANA
registry (a registry is also a format). Yet all of these things have
led to debate in the IETF - for example we have seen debate about
whether a document that only defines a registry can become a Proposed
Standard. It is clear that a TS must be both implementable and
testable - but even this is subject to interpretation by the IESG.
Also see later comments on interoperability testing.
"---------Begin Extract---------
3.2 Applicability Statement (AS)
An Applicability Statement specifies how, and under what
circumstances, one or more TSs may be applied to support a particular
Internet capability. An AS may specify uses for TSs that are not
Internet Standards, as discussed in Section 7.
An AS identifies the relevant TSs and the specific way in which they
are to be combined, and may also specify particular values or ranges
of TS parameters or subfunctions of a TS protocol that must be
implemented. An AS also specifies the circumstances in which the use
of a particular TS is required, recommended, or elective (see section
3.3).
An AS may describe particular methods of using a TS in a restricted
"domain of applicability", such as Internet routers, terminal
servers, Internet systems that interface to Ethernets, or datagram-
based database servers.
-----------End Extract---------"
The community rarely creates this sort of separate AS. The IETF has
been reluctant to put ASes on the standards track: they cannot be
implemented and tested. (See comments below on section 4.1.2.)
Today, an AS is typically included as a separate section in the
Carpenter Expires January 3, 2009 [Page 7]
Internet-Draft RFC 2026 practice July 2008
Technical Specification.
"---------Begin Extract---------
The broadest type of AS is a comprehensive conformance specification,
-----------End Extract---------"
The IETF community has shown reluctance to be involved in conformance
specifications.
"---------Begin Extract---------
commonly called a "requirements document", for a particular class of
Internet systems, such as Internet routers or Internet hosts.
-----------End Extract---------"
Today, we use the word "requirements" much more broadly, often as a
front-end document when a WG is starting out.
"---------Begin Extract---------
An AS may not have a higher maturity level in the standards track
than any standards-track TS on which the AS relies (see section 4.1).
For example, a TS at Draft Standard level may be referenced by an AS
at the Proposed Standard or Draft Standard level, but not by an AS at
the Standard level.
-----------End Extract---------"
There is nothing specific to ASes in this rule; it is applied
globally wherever normative references occur. See comment below on
4.2.4.
"---------Begin Extract---------
3.3 Requirement Levels
-----------End Extract---------"
This section provides the basis on which the IETF's normative
keywords [RFC2119] are built.
"---------Begin Extract---------
Carpenter Expires January 3, 2009 [Page 8]
Internet-Draft RFC 2026 practice July 2008
...
The "Official Protocol Standards" RFC (STD1) lists a general
requirement level for each TS, using the nomenclature defined in this
section. This RFC is updated periodically. In many cases, more
detailed descriptions of the requirement levels of particular
protocols and of individual features of the protocols will be found
in appropriate ASs.
-----------End Extract---------"
As noted, STD1 is rarely updated today. How this is really done in
the RFC archive is an operational matter. The concept and format of
STD1 long predated the availability of on-line hyperlinked
information.
"---------Begin Extract---------
4. THE INTERNET STANDARDS TRACK
...
4.1.1 Proposed Standard
...
The IESG may require implementation and/or operational experience
prior to granting Proposed Standard status to a specification that
materially affects the core Internet protocols or that specifies
behavior that may have significant operational impact on the
Internet.
-----------End Extract---------"
Note that for many years the Routing Area essentially applied the
Draft Standard rules at Proposed Standard level [RFC1264], but
recently dropped this [RFC4794].
"---------Begin Extract---------
...
Implementors should treat Proposed Standards as immature
specifications. It is desirable to implement them in order to gain
experience and to validate, test, and clarify the specification.
However, since the content of Proposed Standards may be changed if
problems are found or better solutions are identified, deploying
implementations of such standards into a disruption-sensitive
environment is not recommended.
-----------End Extract---------"
It is well known that to a large extent this warning has been
ignored, and that the Internet "runs on Proposed Standards." Also,
Carpenter Expires January 3, 2009 [Page 9]
Internet-Draft RFC 2026 practice July 2008
as the MIB doctors have observed, some types of spec may benefit from
being recycled at this level rather than being "promoted." In
reality today:
1. Proposed Standard (PS) is the preliminary level.
2. Implementors should be aware that a PS may be revised or even
withdrawn.
3. It is nevertheless common to use PS implementations
operationally.
4. Many documents spend their entire active life as PS.
5. Certain types of specification are likely to be recycled at PS as
they evolve rather than being promoted. (Sometimes this is
simply a result of complexity, but other times it's due to
intrinsic difficulties in interoperability testing and normative
dependencies.)
"---------Begin Extract---------
4.1.2 Draft Standard
A specification from which at least two independent and interoperable
implementations from different code bases have been developed, and
for which sufficient successful operational experience has been
obtained, may be elevated to the "Draft Standard" level. For the
purposes of this section, "interoperable" means to be functionally
equivalent or interchangeable components of the system or process in
which they are used. If patented or otherwise controlled technology
is required for implementation, the separate implementations must
also have resulted from separate exercise of the licensing process.
Elevation to Draft Standard is a major advance in status, indicating
a strong belief that the specification is mature and will be useful.
The requirement for at least two independent and interoperable
implementations applies to all of the options and features of the
specification.
-----------End Extract---------"
At least four significant questions arise repeatedly in interpreting
this, which a WG or author may need to discuss with their AD while
preparing a document for DS status.
1. What is a "feature"? This can be interpreted in many ways. For
a TLV field is every separate type code a feature? Is every
normative keyword [RFC2119] a feature?
2. Is it acceptable if features A and B are shown to be
interoperable between implementations X and Y, and features C and
D are shown to be interoperable between implentations P and Q?
In that case we have shown interoperability of features A, B, C
and D but have not shown that any implementation successfully
Carpenter Expires January 3, 2009 [Page 10]
Internet-Draft RFC 2026 practice July 2008
interoperates with all of them.
At least for the strong security requirement of BCP 61 [RFC3365],
the Security Area, with the support of the IESG, has often
insisted that specifications include at least one mandatory-to-
implement strong security mechanism to guarantee universal
interoperability.
3. Is it acceptable if both implementations X and Y show
interoperability with implementation Q, but the implementor of Q
is not party to the tests and does not make any statements about
features supported? In other words Q has merely served as an
active mirror in the tests.
4. How should we handle the issue of "single-ended" technical
specifications such as data formats, where there is no new
protocol whose interoperation we can verify? A practical
solution for MIBs has been documented [RFC2438].
"---------Begin Extract---------
In cases in which one or more options or features
have not been demonstrated in at least two interoperable
implementations, the specification may advance to the Draft Standard
level only if those options or features are removed.
The Working Group chair is responsible for documenting the specific
implementations which qualify the specification for Draft or Internet
Standard status along with documentation about testing of the
interoperation of these implementations. The documentation must
include information about the support of each of the individual
options and features. This documentation should be submitted to the
Area Director with the protocol action request. (see Section 6)
-----------End Extract---------"
The database of reports collected over the years is at
<http://www.ietf.org/IESG/implementation.html>. The quality is
highly variable and some are very sparse and uninformative.
"---------Begin Extract---------
4.1.3 Internet Standard
...
A specification that reaches the status of Standard is assigned a
number in the STD series while retaining its RFC number.
-----------End Extract---------"
There is sometimes also an acronym or mnemonic associated with an STD
Carpenter Expires January 3, 2009 [Page 11]
Internet-Draft RFC 2026 practice July 2008
designation, e.g. "SMTP" or "SNMP". However, there is no consistent
mechanism for assigning acronyms, and the STD numbers are not
associated with PS and DS documents that obsolete or update an STD
document.
"---------Begin Extract---------
4.2.1 Experimental
The "Experimental" designation typically denotes a specification that
is part of some research or development effort. Such a specification
is published for the general information of the Internet technical
community and as an archival record of the work, subject only to
editorial considerations and to verification that there has been
adequate coordination with the standards process (see below). An
Experimental specification may be the output of an organized Internet
research effort (e.g., a Research Group of the IRTF), an IETF Working
Group, or it may be an individual contribution.
4.2.2 Informational
An "Informational" specification is published for the general
information of the Internet community, and does not represent an
Internet community consensus or recommendation. The Informational
designation is intended to provide for the timely publication of a
very broad range of responsible informational documents from many
sources, subject only to editorial considerations and to verification
that there has been adequate coordination with the standards process
(see section 4.2.3).
-----------End Extract---------"
The IESG has documented guidelines for classifying documents as
Informational vs Experimental at
<http://www.ietf.org/u/ietfchair/info-exp.html>.
In practice, some Informationals and Experimentals that are published
via IESG Approval are very close to being a TS and are evaluated
almost as carefully as a TS. They may also be precursors of BCPs in
areas where more operational experience is needed.
"---------Begin Extract---------
Specifications that have been prepared outside of the Internet
community and are not incorporated into the Internet Standards
Process by any of the provisions of section 10 may be published as
Informational RFCs, with the permission of the owner and the
concurrence of the RFC Editor.
Carpenter Expires January 3, 2009 [Page 12]
Internet-Draft RFC 2026 practice July 2008
-----------End Extract---------"
This paragraph conflates "outside of the IETF process" and "outside
of the Internet community." Some specifications originate elsewhere
(for example, cryptographic algorithms). These are routinely
published as IESG-approved Informational RFCs, commonly sponsored by
an Area Director rather than being processed by a WG. See
<http://www.ietf.org/IESG/STATEMENTS/ad-sponsoring.html>. IAB and
IRTF documents are normally published as Informational or
Experimental too, without IESG approval [RFC4844]. Other
specifications, such as proprietary specifications or work that did
not find IETF sponsorship, are published as Informational or
Experimental RFCs after independent submission to the RFC Editor and
brief IESG review [RFC3932]. See [RFC4846] for a current
description.
"---------Begin Extract---------
4.2.3 Procedures for Experimental and Informational RFCs
Unless they are the result of IETF Working Group action, documents
intended to be published with Experimental or Informational status
should be submitted directly to the RFC Editor.
-----------End Extract---------"
That's often not what happens. Many of them come via an AD through
the IESG because they are (for example) related to a recently closed
WG etc. These are processed and approved entirely within the IETF
<http://www.ietf.org/IESG/STATEMENTS/ad-sponsoring.html>. But as
noted, the independent submissions track is separate from the IETF
process.
"---------Begin Extract---------
The RFC Editor will
publish any such documents as Internet-Drafts which have not already
been so published.
-----------End Extract---------"
That is inaccurate, i.e. they ask the authors to do so, except
possibly shortly prior to April 1st each year.
"---------Begin Extract---------
In order to differentiate these Internet-Drafts
they will be labeled or grouped in the I-D directory so they are
Carpenter Expires January 3, 2009 [Page 13]

easily recognizable.
-----------End Extract---------"
Not done in practice.
"---------Begin Extract---------
The RFC Editor will wait two weeks after this
publication for comments before proceeding further. The RFC Editor
is expected to exercise his or her judgment concerning the editorial
suitability of a document for publication with Experimental or
Informational status, and may refuse to publish a document which, in
the expert opinion of the RFC Editor, is unrelated to Internet
activity or falls below the technical and/or editorial standard for
RFCs.
-----------End Extract---------"
The RFC Editor is assisted in this by an editorial board
<http://www.rfc-editor.org/edboard.html>.
"---------Begin Extract---------
To ensure that the non-standards track Experimental and Informational
designations are not misused to circumvent the Internet Standards
Process, the IESG and the RFC Editor have agreed that the RFC Editor
will refer to the IESG any document submitted for Experimental or
Informational publication which, in the opinion of the RFC Editor,
may be related to work being done, or expected to be done, within the
IETF community. The IESG shall review such a referred document
within a reasonable period of time, and recommend either that it be
published as originally submitted or referred to the IETF as a
contribution to the Internet Standards Process.
-----------End Extract---------"
The current practice for this is defined in [RFC3932]; also see
[RFC4846].

4.2.4 Historic
A specification that has been superseded by a more recent
specification or is for any other reason considered to be obsolete is
assigned to the "Historic" level. (Purists have suggested that the
word should be "Historical"; however, at this point the use of
"Historic" is historical.)
Note: Standards track specifications normally must not depend on
other standards track specifications which are at a lower maturity
level or on non standards track specifications other than referenced
specifications from other standards bodies. (See Section 7.)
-----------End Extract---------"
The first paragraph has not been implemented consistently. In most
cases a standards track RFC that has been obsoleted by a more recent
version is not listed in the RFC Index as Historic.
The second paragraph is applied generally. Furthermore, a clear
distinction is now required between Normative and Informative
references. Also, the requirement for Normative references to be
published (i.e. not work in progress) is applied to all
specifications, not just the standards track.
Also note the procedures of [RFC3967] and [RFC4897] for allowing
normative reference to less mature documents.

5. BEST CURRENT PRACTICE (BCP) RFCs
The BCP subseries of the RFC series is designed to be a way to
standardize practices and the results of community deliberations. A
BCP document is subject to the same basic set of procedures as
standards track documents and thus is a vehicle by which the IETF
community can define and ratify the community's best current thinking
on a statement of principle or on what is believed to be the best way
to perform some operations or IETF process function.
Historically Internet standards have generally been concerned with
the technical specifications for hardware and software required for
computer communication across interconnected networks. However,
since the Internet itself is composed of networks operated by a great
variety of organizations, with diverse goals and rules, good user
service requires that the operators and administrators of the
Internet follow some common guidelines for policies and operations.
While these guidelines are generally different in scope and style
from protocol standards, their establishment needs a similar process
for consensus building.
-----------End Extract---------"
It is sometimes unclear whether a given document should be standards
track, BCP or informational (and in the end, it may not really
matter). For example, how should the IESG classify a document which
recommends against a particular operational practice that has been
found to be damaging? It might amend a technical specification (by
removing a feature); it might limit the applicability of a protocol
(and therefore be an applicability statement); it might be a BCP
defining a "worst current practice"; or it might fit none of the
above. WGs or authors need to discuss this matter with their AD.
"---------Begin Extract---------
While it is recognized that entities such as the IAB and IESG are
composed of individuals who may participate, as individuals, in the
technical work of the IETF, it is also recognized that the entities
themselves have an existence as leaders in the community. As leaders
in the Internet technical community, these entities should have an
outlet to propose ideas to stimulate work in a particular area, to
raise the community's sensitivity to a certain issue, to make a
statement of architectural principle, or to communicate their
thoughts on other matters. The BCP subseries creates a smoothly
structured way for these management entities to insert proposals into
the consensus-building machinery of the IETF while gauging the
community's view of that issue.
Carpenter Expires January 3, 2009 [Page 16]
Internet-Draft RFC 2026 practice July 2008
-----------End Extract---------"
Although it's not unknown for a BCP to have its origin in the IESG or
IAB, IETF consensus is still needed, as judged by the IESG.
"---------Begin Extract---------
6.1.1 Initiation of Action
A specification that is intended to enter or advance in the Internet
standards track shall first be posted as an Internet-Draft (see
section 2.2) unless it has not changed since publication as an RFC.
It shall remain as an Internet-Draft for a period of time, not less
than two weeks, that permits useful community review, after which a
recommendation for action may be initiated.
A standards action is initiated by a recommendation by the IETF
Working group responsible for a specification to its Area Director,
copied to the IETF Secretariat or, in the case of a specification not
associated with a Working Group, a recommendation by an individual to
the IESG.
-----------End Extract---------"
In practice, individual submissions are recommended to and shepherded
by an AD, who brings them to the IESG just like a WG document. See
<http://www.ietf.org/IESG/STATEMENTS/ad-sponsoring.html>.
"---------Begin Extract---------
6.1.3 Publication
If a standards action is approved, notification is sent to the RFC
Editor and copied to the IETF with instructions to publish the
specification as an RFC. The specification shall at that point be
removed from the Internet-Drafts directory.

"At that point" refers to the moment of publication of the RFC.

6.2 Advancing in the Standards Track
...
Change of status shall result in republication of the specification
as an RFC, except in the rare case that there have been no changes at
all in the specification since the last publication. Generally,
desired changes will be "batched" for incorporation at the next level
in the standards track. However, deferral of changes to the next
standards action on the specification will not always be possible or
desirable; for example, an important typographical error, or a
technical error that does not represent a change in overall function
of the specification, may need to be corrected immediately. In such
cases, the IESG or RFC Editor may be asked to republish the RFC (with
a new number) with corrections, and this will not reset the minimum
time-at-level clock.

When a standards-track specification has not reached the Internet
Standard level but has remained at the same maturity level for
twenty-four (24) months, and every twelve (12) months thereafter
until the status is changed, the IESG shall review the viability of
the standardization effort responsible for that specification and the
usefulness of the technology. Following each such review, the IESG
shall approve termination or continuation of the development effort,
at the same time the IESG shall decide to maintain the specification
at the same maturity level or to move it to Historic status. This
decision shall be communicated to the IETF by electronic mail to the
IETF Announce mailing list to allow the Internet community an
opportunity to comment. This provision is not intended to threaten a
legitimate and active Working Group effort, but rather to provide an
administrative mechanism for terminating a moribund effort.
-----------End Extract---------"
In practice, the IESG relies on working groups, or on initiatives by
members of the community, to propose promotion (or demotion) of
documents. A practical example of demotion is [RFC4450].
"---------Begin Extract---------
6.5 Conflict Resolution and Appeals
-----------End Extract---------"
It's possible to read this as applying only to IESG actions described
in this section 6. The IESG and IAB have preferred to read it as
applying to any IESG decision whatever.

8. NOTICES AND RECORD KEEPING
...
As a practical matter, the formal record of all Internet Standards
Process activities is maintained by the IETF Secretariat, and is the
responsibility of the IETF Secretariat except that each IETF Working
Group is expected to maintain their own email list archive and must
make a best effort to ensure that all traffic is captured and
included in the archives. Also, the Working Group chair is
responsible for providing the IETF Secretariat with complete and
accurate minutes of all Working Group meetings. Internet-Drafts that
have been removed (for any reason) from the Internet-Drafts
directories shall be archived by the IETF Secretariat for the sole
purpose of preserving an historical record of Internet standards
activity and thus are not retrievable except in special
circumstances.
