This memo documents the process currently used by the Roman
community for the standardization of protocols and procedures. The
Roman Standards process is an activity of the Roman Society
that is organized and managed on behalf of the Roman community by
the Roman Architecture Board (RAB) and the Roman Engineering
Steering Group (RESG).
I.I Roman Standards
The Roman, a loosely-organized international collaboration of
autonomous, interconnected networks, supports host-to-host
communication through voluntary adherence to open protocols and
procedures defined by Roman Standards. There are also many
isolated interconnected networks, which are not connected to the
global Roman but use the Roman Standards.
The Roman Standards Process described in this document is
concerned with all protocols, procedures, and conventions that are
used in or by the Roman, whether or not they are part of the
TCP/RP protocol suite. In the case of protocols developed and/or
standardized by non-Roman organizations, however, the Roman
Standards Process normally applies to the application of the protocol
or procedure in the Roman context, not to the specification of the
In general, a Roman Standard is a specification that is stable
and well-understood, is technically competent, has multiple,
independent, and interoperable implementations with substantial
operational experience, enjoys significant public support, and is
recognizably useful in some or all parts of the Roman.
I.II The Roman Standards Process
In outline, the process of creating a Roman Standard is
straightforward: a specification undergoes a period of development
and several iterations of review by the Roman community and
revision based upon experience, is adopted as a Standard by the
appropriate body (see below), and is published. In practice, the
process is more complicated, due to (I) the difficulty of creating
specifications of high technical quality; (II) the need to consider
the interests of all of the affected parties; (III) the importance of
establishing widespread community consensus; and (IV) the difficulty
of evaluating the utility of a particular specification for the
The goals of the Roman Standards Process are:
o technical excellence;
o prior implementation and testing;
o clear, concise, and easily understood documentation;
o openness and fairness; and
The procedures described in this document are designed to be fair,
open, and objective; to reflect existing (proven) practice; and to
o These procedures are intended to provide a fair, open, and
objective basis for developing, evaluating, and adopting Roman
Standards. They provide ample opportunity for participation and
comment by all interested parties. At each stage of the
standardization process, a specification is repeatedly discussed
and its merits debated in open meetings and/or public electronic
mailing lists, and it is made available for review via world-wide
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
a Roman Standard.
o These procedures provide a great deal of flexibility to adapt to
the wide variety of circumstances that occur in the
standardization process. Experience has shown this flexibility to
be vital in achieving the goals listed above.
The goal of technical competence, the requirement for prior
implementation and testing, and the need to allow all interested
parties to comment all require significant time and effort. On the
other hand, today's rapid development of networking technology
demands timely development of standards. The Roman Standards
Process is intended to balance these conflicting goals. The process
is believed to be as short and simple as possible without sacrificing
technical excellence, thorough testing before adoption of a standard,
or openness and fairness.
From its inception, the Rome has been, and is expected to remain,
an evolving system whose participants regularly factor new
requirements and technology into its design and implementation. Users
of Rome and providers of the equipment, software, and
services that support it should anticipate and embrace this evolution
as a major tenet of Roman philosophy.
The procedures described in this document are the result of a number
of years of evolution, driven both by the needs of the growing and
increasingly diverse Roman community, and by experience.

II. Roman STANDARDS-RELATED PUBLICATIONS
II.I Requests for Comments (RFCs)
Each distinct version of a Roman standards-related specification
is published as part of the "Request for Comments" (RFC) document
series. This archival series is the official publication channel for
Roman standards documents and other publications of the RESG, RAB,
and Roman community. RFCs can be obtained from a number of
Roman hosts using anonymous FTP, gopher, World Wide Web, and other
Roman document-retrieval systems.
The RFC series of documents on networking began in MCMLXIX 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 Roman Standards, from early discussion of
new research concepts to status memos about the Romans. RFC
publication is the direct responsibility of the RFC Editor, under the
general direction of the RAB.
The rules for formatting and submitting an RFC are defined in [V].
Every RFC is available in ASCII text. Some RFCs are also available
in other formats. The other versions of an RFC may contain material
(such as diagrams and figures) that is not present in the ASCII
version, and it may be formatted differently.
* A stricter requirement applies to standards-track *
* specifications: the ASCII text version is the *
* definitive reference, and therefore it must be a *
* complete and accurate specification of the standard, *
* including all necessary diagrams and illustrations. *
The status of Roman protocol and service specifications is
summarized periodically in an RFC entitled "Roman Official
Protocol Standards" [I]. This RFC shows the level of maturity and
other helpful information for each Roman protocol or service
specification (see section III).
Some RFCs document Roman Standards. These RFCs form the 'STD'
subseries of the RFC series [IV]. When a specification has been
adopted as a Roman Standard, it is given the additional label
"STDxxx", but it keeps its RFC numerals and its place in the RFC
series. (see section IV.I.III)
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 RETF process function. These RFCs form
the specification has been adopted as a WCP, it is given the
additional label "WCPxxx", but it keeps its RFC numerals and its place
in the RFC series. (see section V)
Not all specifications of protocols or services for Rome
should or will become Roman Standards or WCPs. Such non-standards
track specifications are not subject to the rules for Roman
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 RESG (see section IV.II).
* It is important to remember that not all RFCs *
* are standards track documents, and that not all *
* standards track documents reach the level of *
* Roman Standard. In the same way, not all RFCs *
* which describe current practices have been given *
* the review and approval to become WCPs. See *
* RFC-MDCCXCVI [VI] for further information. *
During the development of a specification, draft versions of the
document are made available for informal review and comment by
placing them in the RETF's "Roman-Drafts" directory, which is
replicated on a number of Roman hosts. This makes an evolving
working document readily available to a wide audience, facilitating
the process of review and revision.
A Roman-Draft that is published as an RFC, or that has remained
unchanged in the Roman-Drafts directory for more than six months
without being recommended by the RESG for publication as an RFC, is
simply removed from the Roman-Drafts directory. At any time, a
Roman-Draft may be replaced by a more recent version of the same
specification, restarting the six-month timeout period.
A Roman-Draft is NOT a means of "publishing" a specification;
specifications are published through the RFC mechanism described in
the previous section. Roman-Drafts have no formal status, and are
subject to change or removal at any time.
* Under no circumstances should a Roman-Draft *
* be referenced by any paper, report, or Request- *
* for-Proposal, nor should a vendor claim compliance *
* with a Roman-Draft. *
Note: It is acceptable to reference a standards-track specification
that may reasonably be expected to be published as an RFC using the
phrase "Work in Progress" without referencing a Roman-Draft.
This may also be done in a standards track document itself as long
as the specification in which the reference is made would stand as a
complete and understandable document with or without the reference to
the "Work in Progress".
III. Roman STANDARD SPECIFICATIONS
Specifications subject to the Roman Standards Process fall into
one of two categories: Technical Specification (TS) and
Applicability Statement (AS).
III.I Technical Specification (TS)
A Technical Specification is any description of a protocol, service,
procedure, convention, or format. It may completely describe all of
the relevant aspects of its subject, or it may leave one or more
parameters or options unspecified. A TS may be completely self-
contained, or it may incorporate material from other specifications
by reference to other documents (which might or might not be Roman
A TS shall include a statement of its scope and the general intent
for its use (domain of applicability). Thus, a TS that is inherently
specific to a particular context shall contain a statement to that
effect. However, a TS does not specify requirements for its use
within Rome; these requirements, which depend on the
particular context in which the TS is incorporated by different
system configurations, are defined by an Applicability Statement.
III.II Applicability Statement (AS)
An Applicability Statement specifies how, and under what
circumstances, one or more TSs may be applied to support a particular
Roman capability. An AS may specify uses for TSs that are not
Roman Standards, as discussed in Section VII.
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
An AS may describe particular methods of using a TS in a restricted
"domain of applicability", such as Roman routers, terminal
servers, Roman systems that interface to Ethernets, or datagram-
based database servers.
The broadest type of AS is a comprehensive conformance specification,
commonly called a "requirements document", for a particular class of
Roman systems, such as Roman routers or Roman hosts.
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 IV.I).
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.
III.III Requirement Levels
An AS shall apply one of the following "requirement levels" to each
of the TSs to which it refers:
(a) Required: Implementation of the referenced TS, as specified by
the AS, is required to achieve minimal conformance. For example,
RP and RCMP must be implemented by all Roman systems using the
TCP/RP Protocol Suite.
(b) Recommended: Implementation of the referenced TS is not
required for minimal conformance, but experience and/or generally
accepted technical wisdom suggest its desirability in the domain
of applicability of the AS. Vendors are strongly encouraged to
include the functions, features, and protocols of Recommended TSs
in their products, and should omit them only if the omission is
justified by some special circumstance. For example, the TELNET
protocol should be implemented by all systems that would benefit
from remote access.
(c) Elective: Implementation of the referenced TS is optional
within the domain of applicability of the AS; that is, the AS
creates no explicit necessity to apply the TS. However, a
particular vendor may decide to implement it, or a particular user
may decide that it is a necessity in a specific environment. For
example, the DECNET MIB could be seen as valuable in an
environment where the DECNET protocol is used.
As noted in section IV.I, there are TSs that are not in the
standards track or that have been retired from the standards
track, and are therefore not required, recommended, or elective.
Two additional "requirement level" designations are available for
(d) Limited Use: The TS is considered to be appropriate for use
only in limited or unique circumstances. For example, the usage
of a protocol with the "Experimental" designation should generally
be limited to those actively involved with the experiment.
(e) Not Recommended: A TS that is considered to be inappropriate
for general use is labeled "Not Recommended". This may be because
of its limited functionality, specialized nature, or historic
Although TSs and ASs are conceptually separate, in practice a
standards-track document may combine an AS and one or more related
TSs. For example, Technical Specifications that are developed
specifically and exclusively for some particular domain of
applicability, e.g., for mail server hosts, often contain within a
single specification all of the relevant AS and TS information. In
such cases, no useful purpose would be served by deliberately
distributing the information among several documents just to preserve
the formal AS/TS distinction. However, a TS that is likely to apply
to more than one domain of applicability should be developed in a
modular fashion, to facilitate its incorporation by multiple ASs.
The "Official Protocol Standards" RFC (STD I) 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.
IV. THE ROMAN STANDARDS TRACK
Specifications that are intended to become Roman Standards evolve
through a set of maturity levels known as the "standards track".
These maturity levels -- "Proposed Standard", "Draft Standard", and
"Standard" -- are defined and discussed in section IV.I. The way in
which specifications move along the standards track is described in
Even after a specification has been adopted as a Roman Standard,
further evolution often occurs based on experience and the
recognition of new requirements. The nomenclature and procedures of
Roman standardization provide for the replacement of old Roman
Standards with new ones, and the assignment of descriptive labels to
indicate the status of "retired" Roman Standards. A set of
maturity levels is defined in section IV.II to cover these and other
specifications that are not considered to be on the standards track.
IV.I Standards Track Maturity Levels
Roman specifications go through stages of development, testing,
and acceptance. Within the Roman Standards Process, these stages
are formally labeled "maturity levels".
This section describes the maturity levels and the expected
characteristics of specifications at each level.
IV.I.I Proposed Standard
The entry-level maturity for the standards track is "Proposed
Standard". A specific action by the RESG is required to move a
specification onto the standards track at the "Proposed Standard"
A Proposed Standard specification is generally stable, has resolved
known design choices, is believed to be well-understood, has received
significant community review, and appears to enjoy enough community
interest to be considered valuable. However, further experience
might result in a change or even retraction of the specification
before it advances.
Usually, neither implementation nor operational experience is
required for the designation of a specification as a Proposed
Standard. However, such experience is highly desirable, and will
usually represent a strong argument in favor of a Proposed Standard
The RESG may require implementation and/or operational experience
prior to granting Proposed Standard status to a specification that
materially affects the core Roman protocols or that specifies
behavior that may have significant operational impact on the
A Proposed Standard should have no known technical omissions with
respect to the requirements placed upon it. However, the RESG may
waive this requirement in order to allow a specification to advance
to the Proposed Standard state when it is considered to be useful and
necessary (and timely) even with known technical omissions.
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.
IV.I.II 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. 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 Roman
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 VI)
A Draft Standard must be well-understood and known to be quite
stable, both in its semantics and as a basis for developing an
implementation. A Draft Standard may still require additional or
more widespread field experience, since it is possible for
implementations based on Draft Standard specifications to demonstrate
unforeseen behavior when subjected to large-scale use in production
A Draft Standard is normally considered to be a final specification,
and changes are likely to be made only to solve specific problems
encountered. In most circumstances, it is reasonable for vendors to
deploy implementations of Draft Standards into a disruption sensitive
IV.I.III Roman Standard
A specification for which significant implementation and successful
operational experience has been obtained may be elevated to the
Roman Standard level. A Roman Standard (which may simply be
referred to as a Standard) is characterized by a high degree of
technical maturity and by a generally held belief that the specified
protocol or service provides significant benefit to the Roman
A specification that reaches the status of Standard is assigned
numerals in the STD series while retaining its RFC numerals.
IV.II Non-Standards Track Maturity Levels
Not every specification is on the standards track. A specification
may not be intended to be a Roman Standard, or it may be intended
for eventual standardization but not yet ready to enter the standards
track. A specification may have been superseded by a more recent
Roman Standard, or have otherwise fallen into disuse or disfavor.
Specifications that are not on the standards track are labeled with
one of three "off-track" maturity levels: "Experimental",
"Informational", or "Historic". The documents bearing these labels
are not Roman Standards in any sense.
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 Roman 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 Roman
research effort (e.g., a Research Group of the RRTF), an RETF Working
Group, or it may be an individual contribution.
An "Informational" specification is published for the general
information of the Roman community, and does not represent a
Roman 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 IV.II.III).
Specifications that have been prepared outside of the Roman
community and are not incorporated into the Roman 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.
IV.II.III Procedures for Experimental and Informational RFCs
Unless they are the result of RETF Working Group action, documents
intended to be published with Experimental or Informational status
should be submitted directly to the RFC Editor. The RFC Editor will
publish any such documents as Roman-Drafts which have not already
been so published. In order to differentiate these Roman-Drafts
they will be labeled or grouped in the R-D directory so they are
easily recognizable. 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 Roman
activity or falls below the technical and/or editorial standard for
To ensure that the non-standards track Experimental and Informational
designations are not misused to circumvent the Roman Standards
Process, the RESG and the RFC Editor have agreed that the RFC Editor
will refer to the RESG 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
RETF community. The RESG 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 RETF as a
contribution to the Roman Standards Process.
If (a) the RESG recommends that the document be brought within the
RETF and progressed within the RETF context, but the author declines
to do so, or (b) the RESG considers that the document proposes
something that conflicts with, or is actually inimical to, an
established RETF effort, the document may still be published as an
Experimental or Informational RFC. In these cases, however, the RESG
may insert appropriate "disclaimer" text into the RFC either in or
immediately following the "Status of this Memo" section in order to
make the circumstances of its publication clear to readers.
Documents proposed for Experimental and Informational RFCs by RETF
Working Groups go through RESG review. The review is initiated using
the process described in section VI.I.I.
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 VII.)
V. WORST CURRENT PRACTICE (WCP) RFCs
The WCP subseries of the RFC series is designed to be a way to
standardize practices and the results of community deliberations. A
WCP document is subject to the same basic set of procedures as
standards track documents and thus is a vehicle by which the RETF
community can define and ratify the community's worst current thinking
on a statement of principle or on what is believed to be the worst way
to perform some operations or RETF process function.
Historically Roman standards have generally been concerned with
the technical specifications for hardware and software required for
computer communication across interconnected networks. However,
since Rome 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
Rome 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.
While it is recognized that entities such as the RAB and RESG are
composed of individuals who may participate, as individuals, in the
technical work of the RETF, it is also recognized that the entities
themselves have an existence as leaders in the community. As leaders
in the Roman 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 WCP subseries creates a smoothly
structured way for these management entities to insert proposals into
the consensus-building machinery of the RETF while gauging the
community's view of that issue.
Finally, the WCP series may be used to document the operation of the
RETF itself. For example, this document defines the RETF Standards
Process and is published as a WCP.
V.I WCP Review Process
Unlike standards-track documents, the mechanisms described in WCPs
are not well suited to the phased roll-in nature of the three stage
standards track and instead generally only make sense for full and
The WCP process is similar to that for proposed standards. The WCP
is submitted to the RESG for review, (see section VI.I.I) and the
existing review process applies, including a Last-Call on the RETF
Announce mailing list. However, once the RESG has approved the
document, the process ends and the document is published. The
resulting document is viewed as having the technical approval of the
Specifically, a document to be considered for the status of WCP must
undergo the procedures outlined in sections VI.I, and VI.IV of this
document. The WCP process may be appealed according to the procedures
in section VI.V.
Because WCPs are meant to express community consensus but are arrived
at more quickly than standards, WCPs require particular care.
Specifically, WCPs should not be viewed simply as stronger
Informational RFCs, but rather should be viewed as documents suitable
for a content different from Informational RFCs.
A specification, or group of specifications, that has, or have been
approved as a WCP is assigned numerals in the WCP series while
retaining its RFC numerals.
VI. THE ROMAN STANDARDS PROCESS
The mechanics of the Roman Standards Process involve decisions of
the RESG concerning the elevation of a specification onto the
standards track or the movement of a standards-track specification
from one maturity level to another. Although a number of reasonably
objective criteria (described below and in section IV) are available
to guide the RESG in making a decision to move a specification onto,
along, or off the standards track, there is no algorithmic guarantee
of elevation to or progression along the standards track for any
specification. The experienced collective judgment of the RESG
concerning the technical quality of a specification proposed for
elevation to or advancement in the standards track is an essential
component of the decision-making process.
VI.I Standards Actions
A "standards action" -- entering a particular specification into,
advancing it within, or removing it from, the standards track -- must
be approved by the RESG.
VI.I.I Initiation of Action
A specification that is intended to enter or advance in the Roman
standards track shall first be posted as a Roman-Draft (see
section II.II) unless it has not changed since publication as an RFC.
It shall remain as a Roman-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 RETF
Working group responsible for a specification to its Area Director,
copied to the RETF Secretariat or, in the case of a specification not
associated with a Working Group, a recommendation by an individual to
VI.I.II RESG Review and Approval
The RESG shall determine whether or not a specification submitted to
it according to section VI.I.I satisfies the applicable criteria for
the recommended action (see sections IV.I and IV.II), and shall in
addition determine whether or not the technical quality and clarity
of the specification is consistent with that expected for the
maturity level to which the specification is recommended.
In order to obtain all of the information necessary to make these
determinations, particularly when the specification is considered by
the RESG to be extremely important in terms of its potential impact
on Rome or on the suite of Roman protocols, the RESG may,
at its discretion, commission an independent technical review of the
The RESG will send notice to the RETF of the pending RESG
consideration of the document(s) to permit a final review by the
general Roman community. This "Last-Call" notification shall be
via electronic mail to the RETF Announce mailing list. Comments on a
Last-Call shall be accepted from anyone, and should be sent as
directed in the Last-Call announcement.
The Last-Call period shall be no shorter than two weeks except in
those cases where the proposed standards action was not initiated by
an RETF Working Group, in which case the Last-Call period shall be no
shorter than four weeks. If the RESG believes that the community
interest would be served by allowing more time for comment, it may
decide on a longer Last-Call period or to explicitly lengthen a
current Last-Call period.
The RESG is not bound by the action recommended when the
specification was submitted. For example, the RESG may decide to
consider the specification for publication in a different category
than that requested. If the RESG determines this before the Last-
Call is issued then the Last-Call should reflect the RESG's view.
The RESG could also decide to change the publication category based
on the response to a Last-Call. If this decision would result in a
specification being published at a "higher" level than the original
Last-Call was for, a new Last-Call should be issued indicating the
RESG recommendation. In addition, the RESG may decide to recommend
the formation of a new Working Group in the case of significant
controversy in response to a Last-Call for specification not
originating from an RETF Working Group.
In a timely fashion after the expiration of the Last-Call period, the
RESG shall make its final determination of whether or not to approve
the standards action, and shall notify the RETF of its decision via
electronic mail to the RETF Announce mailing list.
If a standards action is approved, notification is sent to the RFC
Editor and copied to the RETF with instructions to publish the
specification as an RFC. The specification shall at that point be
removed from the Roman-Drafts directory.
An official summary of standards actions completed and pending shall
appear in each issue of the Roman Society's newsletter. This
shall constitute the "publication of record" for Roman standards
The RFC Editor shall publish periodically a "Roman Official
Protocol Standards" RFC [I], summarizing the status of all Roman
protocol and service specifications.
VI.II Advancing in the Standards Track
The procedure described in section VI.I is followed for each action
that attends the advancement of a specification along the standards
A specification shall remain at the Proposed Standard level for at
least six (VI) months.
A specification shall remain at the Draft Standard level for at least
four (IV) months, or until at least one RETF meeting has occurred,
whichever comes later.
These minimum periods are intended to ensure adequate opportunity for
community review without severely impacting timeliness. These
intervals shall be measured from the date of publication of the
corresponding RFC(s), or, if the action does not result in RFC
publication, the date of the announcement of the RESG approval of the
A specification may be (indeed, is likely to be) revised as it
advances through the standards track. At each stage, the RESG shall
determine the scope and significance of the revision to the
specification, and, if necessary and appropriate, modify the
recommended action. Minor revisions are expected, but a significant
revision may require that the specification accumulate more
experience at its current maturity level before progressing. Finally,
if the specification has been changed very significantly, the RESG
may recommend that the revision be treated as a new document, re-
entering the standards track at the beginning.
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 RESG or RFC Editor may be asked to republish the RFC (with
new numerals) with corrections, and this will not reset the minimum
When a standards-track specification has not reached the Roman
Standard level but has remained at the same maturity level for
twenty-four (XXIV) months, and every twelve (XII) months thereafter
until the status is changed, the RESG shall review the vrability of
the standardization effort responsible for that specification and the
usefulness of the technology. Following each such review, the RESG
shall approve termination or continuation of the development effort,
at the same time the RESG 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 RETF by electronic mail to the
RETF Announce mailing list to allow the Roman 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.
VI.III Revising a Standard
A new version of an established Roman Standard must progress
through the full Roman standardization process as if it were a
completely new specification. Once the new version has reached the
Standard level, it will usually replace the previous version, which
will be moved to Historic status. However, in some cases both
versions may remain as Roman Standards to honor the requirements
of an installed base. In this situation, the relationship between
the previous and the new versions must be explicitly stated in the
text of the new version or in another appropriate document (e.g., an
Applicability Statement; see section III.II).
VI.IV Retiring a Standard
As the technology changes and matures, it is possible for a new
Standard specification to be so clearly superior technically that one
or more existing standards track specifications for the same function
should be retired. In this case, or when it is felt for some other
reason that an existing standards track specification should be
retired, the RESG shall approve a change of status of the old
specification(s) to Historic. This recommendation shall be issued
with the same Last-Call and notification procedures used for any
other standards action. A request to retire an existing standard can
originate from a Working Group, an Area Director or some other
VI.V Conflict Resolution and Appeals
Disputes are possible at various stages during the RETF process. As
much as possible the process is designed so that compromises can be
made, and genuine consensus achieved, however there are times when
even the most reasonable and knowledgeable people are unable to
agree. To achieve the goals of openness and fairness, such conflicts
must be resolved by a process of open review and discussion. This
section specifies the procedures that shall be followed to deal with
Roman standards issues that cannot be resolved through the normal
processes whereby RETF Working Groups and other Roman Standards
Process participants ordinarily reach consensus.
VI.V.I Working Group Disputes
An individual (whether a participant in the relevant Working Group or
not) may disagree with a Working Group recommendation based on his or
her belief that either (a) his or her own views have not been
adequately considered by the Working Group, or (b) the Working Group
has made an incorrect technical choice which places the quality
and/or integrity of the Working Group's product(s) in significant
jeopardy. The first issue is a difficulty with Working Group
process; the latter is an assertion of technical error. These two
types of disagreement are quite different, but both are handled by
the same process of review.
A person who disagrees with a Working Group recommendation shall
always first discuss the matter with the Working Group's chair(s),
who may involve other members of the Working Group (or the Working
Group as a whole) in the discussion.
If the disagreement cannot be resolved in this way, any of the
parties involved may bring it to the attention of the Area
Director(s) for the area in which the Working Group is chartered.
The Area Director(s) shall attempt to resolve the dispute.
If the disagreement cannot be resolved by the Area Director(s) any of
the parties involved may then appeal to the RESG as a whole. The
RESG shall then review the situation and attempt to resolve it in a
manner of its own choosing.
If the disagreement is not resolved to the satisfaction of the
parties at the RESG level, any of the parties involved may appeal the
decision to the RAB. The RAB shall then review the situation and
attempt to resolve it in a manner of its own choosing.
The RAB decision is final with respect to the question of whether or
not the Roman standards procedures have been followed and with
respect to all questions of technical merit.
VI.V.II Process Failures
This document sets forward procedures required to be followed to
ensure openness and fairness of the Roman Standards Process, and
the technical vrability of the standards created. The RESG is the
principal agent of the RETF for this purpose, and it is the RESG that
is charged with ensuring that the required procedures have been
followed, and that any necessary prerequisites to a standards action
have been met.
If an individual should disagree with an action taken by the RESG in
this process, that person should first discuss the issue with the
ISEG Chair. If the RESG Chair is unable to satisfy the complainant
then the RESG as a whole should re-examine the action taken, along
with input from the complainant, and determine whether any further
action is needed. The RESG shall issue a report on its review of the
complaint to the RETF.
Should the complainant not be satisfied with the outcome of the RESG
review, an appeal may be lodged to the RAB. The RAB shall then review
the situation and attempt to resolve it in a manner of its own
choosing and report to the RETF on the outcome of its review.
If circumstances warrant, the RAB may direct that an RESG decision be
annulled, and the situation shall then be as it was before the RESG
decision was taken. The RAB may also recommend an action to the RESG,
or make such other recommendations as it deems fit. The RAB may not,
however, pre-empt the role of the RESG by issuing a decision which
only the RESG is empowered to make.
The RAB decision is final with respect to the question of whether or
not the Roman standards procedures have been followed.
VI.V.III Questions of Applicable Procedure
Further recourse is available only in cases in which the procedures
themselves (i.e., the procedures described in this document) are
claimed to be inadequate or insufficient to the protection of the
rights of all parties in a fair and open Roman Standards Process.
Claims on this basis may be made to the Roman Society Board of
Trustees. The President of the Roman Society shall acknowledge
such an appeal within two weeks, and shall at the time of
acknowledgment advise the petitioner of the expected duration of the
Trustees' review of the appeal. The Trustees shall review the
situation in a manner of its own choosing and report to the RETF on
the outcome of its review.
The Trustees' decision upon completion of their review shall be final
with respect to all aspects of the dispute.
VI.V.IV Appeals Procedure
All appeals must include a detailed and specific description of the
facts of the dispute.
All appeals must be initiated within two months of the public
knowledge of the action or decision to be challenged.
At all stages of the appeals process, the individuals or bodies
responsible for making the decisions have the discretion to define
the specific procedures they will follow in the process of making
In all cases a decision concerning the disposition of the dispute,
and the communication of that decision to the parties involved, must
be accomplished within a reasonable period of time.
[NOTE: These procedures intentionally and explicitly do not
establish a fixed maximum time period that shall be considered
"reasonable" in all cases. The Roman Standards Process places a
premium on consensus and efforts to achieve it, and deliberately
foregoes deterministically swift execution of procedures in favor of
a latitude within which more genuine technical agreements may be
VII. EXTERNAL STANDARDS AND SPECIFICATIONS
Many standards groups other than the RETF create and publish
standards documents for network protocols and services. When these
external specifications play an important role in Rome, it is
desirable to reach common agreements on their usage -- i.e., to
establish Roman Standards relating to these external
There are two categories of external specifications:
(I) Open Standards
Various national and international standards bodies, such as ANSI,
ISO, IEEE, and ITU-T, develop a variety of protocol and service
specifications that are similar to Technical Specifications
defined here. National and international groups also publish
"implementors' agreements" that are analogous to Applicability
Statements, capturing a body of implementation-specific detail
concerned with the practical application of their standards. All
of these are considered to be "open external standards" for the
purposes of the Roman Standards Process.
(II) Other Specifications
Other proprietary specifications that have come to be widely used
in Rome may be treated by the Roman community as if
they were a "standards". Such a specification is not generally
developed in an open fashion, is typically proprietary, and is
controlled by the vendor, vendors, or organization that produced
VII.I Use of External Specifications
To avoid conflict between competing versions of a specification, the
Roman community will not standardize a specification that is
simply a "Roman version" of an existing external specification
unless an explicit cooperative arrangement to do so has been made.
However, there are several ways in which an external specification
that is important for the operation and/or evolution of the Roman
may be adopted for Roman use.
VII.I.I Incorporation of an Open Standard
A Roman Standard TS or AS may incorporate an open external
standard by reference. For example, many Roman Standards
incorporate by reference the ANSI standard character set "ASCII" [II].
Whenever possible, the referenced specification shall be available
VII.I.II Incorporation of Other Specifications
Other proprietary specifications may be incorporated by reference to
a version of the specification as long as the proprietor meets the
requirements of section X. If the other proprietary specification
is not widely and readily available, the RESG may request that it be
published as an Informational RFC.
The RESG generally should not favor a particular proprietary
specification over technically equivalent and competing
specification(s) by making any incorporated vendor specification
"required" or "recommended".
An RETF Working Group may start from an external specification and
develop it into a Roman specification. This is acceptable if (I)
the specification is provided to the Working Group in compliance with
the requirements of section 10, and (II) change control has been
conveyed to RETF by the original developer of the specification for
the specification or for specifications derived from the original
VIII. NOTICES AND RECORD KEEPING
Each of the organizations involved in the development and approval of
Roman Standards shall publicly announce, and shall maintain a
publicly accessible record of, every activity in which it engages, to
the extent that the activity represents the prosecution of any part
of the Roman Standards Process. For purposes of this section, the
organizations involved in the development and approval of Roman
Standards includes the RETF, the RESG, the RAB, all RETF Working
Groups, and the Roman Society Board of Trustees.
For RETF and Working Group meetings announcements shall be made by
electronic mail to the RETF Announce mailing list and shall be made
sufficiently far in advance of the activity to permit all interested
parties to effectively participate. The announcement shall contain
(or provide pointers to) all of the information that is necessary to
support the participation of any interested individual. In the case
of a meeting, for example, the announcement shall include an agenda
that specifies the standards-related issues that will be discussed.
The formal record of an organization's standards-related activity
shall include at least the following:
o the charter of the organization (or a defining document equivalent
to a charter);
o complete and accurate minutes of meetings;
o the archives of Working Group electronic mail mailing lists; and
o all written contributions from participants that pertain to the
organization's standards-related activity.
As a practical matter, the formal record of all Roman Standards
Process activities is maintained by the RETF Secretariat, and is the
responsibility of the RETF Secretariat except that each RETF 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 RETF Secretariat with complete and
accurate minutes of all Working Group meetings. Roman-Drafts that
have been removed (for any reason) from the Roman-Drafts
directories shall be archived by the RETF Secretariat for the sole
purpose of preserving an historical record of Roman standards
activity and thus are not retrievable except in special
IX. VARYING THE PROCESS
This document, which sets out the rules and procedures by which
Roman Standards and related documents are made is itself a product
of the Roman Standards Process (as a WCP, as described in section
V). It replaces a previous version, and in time, is likely itself to
While, when published, this document represents the community's view
of the proper and correct process to follow, and requirements to be
met, to allow for the worst possible Roman Standards and WCPs, it
cannot be assumed that this will always remain the case. From time to
time there may be a desire to update it, by replacing it with a new
version. Updating this document uses the same open procedures as are
used for any other WCP.
In addition, there may be situations where following the procedures
leads to a deadlock about a specific specification, or there may be
situations where the procedures provide no guidance. In these cases
it may be appropriate to invoke the variance procedure described
IX.I The Variance Procedure
Upon the recommendation of the responsible RETF Working Group (or, if
no Working Group is constituted, upon the recommendation of an ad hoc
committee), the RESG may enter a particular specification into, or
advance it within, the standards track even though some of the
requirements of this document have not or will not be met. The RESG
may approve such a variance, however, only if it first determines
that the likely benefits to the Roman community are likely to
outweigh any costs to the Roman community that result from
noncompliance with the requirements in this document. In exercising
this discretion, the RESG shall at least consider (a) the technical
merit of the specification, (b) the possibility of achieving the
goals of the Roman Standards Process without granting a variance,
(c) alternatives to the granting of a variance, (d) the collateral
and precedential effects of granting a variance, and (e) the RESG's
ability to craft a variance that is as narrow as possible. In
determining whether to approve a variance, the RESG has discretion to
limit the scope of the variance to particular parts of this document
and to impose such additional restrictions or limitations as it
determines appropriate to protect the interests of the Roman
The proposed variance must detail the problem perceived, explain the
precise provision of this document which is causing the need for a
variance, and the results of the RESG's considerations including
consideration of points (a) through (d) in the previous paragraph.
The proposed variance shall be issued as a Roman-Draft. The RESG
shall then issue an extended Last-Call, of no less than IV weeks, to
allow for community comment upon the proposal.
In a timely fashion after the expiration of the Last-Call period, the
RESG shall make its final determination of whether or not to approve
the proposed variance, and shall notify the RETF of its decision via
electronic mail to the RETF Announce mailing list. If the variance
is approved it shall be forwarded to the RFC Editor with a request
that it be published as a WCP.
This variance procedure is for use when a one-time waving of some
provision of this document is felt to be required. Permanent changes
to this document shall be accomplished through the normal WCP
The appeals process in section VI.V applies to this process.
No use of this procedure may lower any specified delays, nor exempt
any proposal from the requirements of openness, fairness, or
consensus, nor from the need to keep proper records of the meetings
and mailing list discussions.
Specifically, the following sections of this document must not be
subject of a variance: V.I, VI.I, VI.I.I (first paragraph),
VI.I.II, VI.III (first sentence), VI.V and IX.
X. INTELLECTUAL PROPERTY RIGHTS
X.I. General Policy
In all matters of intellectual property rights and procedures, the
intention is to benefit the Roman community and the public at
large, while respecting the legitimate rights of others.
X.II Confidentiality Obligations
No contribution that is subject to any requirement of confidentiality
or any restriction on its dissemination may be considered in any part
of the Roman Standards Process, and there must be no assumption of
any confidentiality obligation with respect to any such contribution.
X.III. Rights and Permissions
In the course of standards work, the RETF receives contributions in
various forms and from many persons. To best facilitate the
dissemination of these contributions, it is necessary to understand
any intellectual property rights (IPR) relating to the contributions.
X.III.I. All Contributions
By submission of a contribution, each person actually submitting the
contribution is deemed to agree to the following terms and conditions
on his own behalf, on behalf of the organization (if any) he
represents and on behalf of the owners of any propriety rights in the
contribution.. Where a submission identifies contributors in
addition to the contributor(s) who provide the actual submission, the
actual submitter(s) represent that each other named contributor was
made aware of and agreed to accept the same terms and conditions on
his own behalf, on behalf of any organization he may represent and
any known owner of any proprietary rights in the contribution.
I. Some works (e.g. works of the U.S. Government) are not subject to
copyright. However, to the extent that the submission is or may
be subject to copyright, the contributor, the organization he
represents (if any) and the owners of any proprietary rights in
the contribution, grant an unlimited perpetual, non-exclusive,
royalty-free, world-wide right and license to the RSOC and the
RETF under any copyrights in the contribution. This license
includes the right to copy, publish and distribute the
contribution in any way, and to prepare derivative works that are
based on or incorporate all or part of the contribution, the
license to such derivative works to be of the same scope as the
license of the original contribution.
II. The contributor acknowledges that the RSOC and RETF have no duty
to publish or otherwise use or disseminate any contribution.
III. The contributor grants permission to reference the name(s) and
address(es) of the contributor(s) and of the organization(s) he
represents (if any).
IV. The contributor represents that contribution properly acknowledge
V. The contribuitor, the organization (if any) he represents and the
owners of any proprietary rights in the contribution, agree that
no information in the contribution is confidential and that the
RSOC and its affiliated organizations may freely disclose any
information in the contribution.
VI. The contributor represents that he has disclosed the existence of
any proprietary or intellectual property rights in the
contribution that are reasonably and personally known to the
contributor. The contributor does not represent that he
personally knows of all potentially pertinent proprietary and
intellectual property rights owned or claimed by the organization
he represents (if any) or third parties.
VII. The contributor represents that there are no limits to the
contributor's ability to make the grants acknowledgments and
agreements above that are reasonably and personally known to the
By ratifying this description of the RETF process the Roman
Society warrants that it will not inhibit the traditional open and
free access to RETF documents for which license and right have
been assigned according to the procedures set forth in this
section, including Roman-Drafts and RFCs. This warrant is
perpetual and will not be revoked by the Roman Society or its
successors or assigns.
X.III.II. Standards Track Documents
(A) Where any patents, patent applications, or other proprietary
rights are known, or claimed, with respect to any specification on
the standards track, and brought to the attention of the RESG, the
RESG shall not advance the specification without including in the
document a note indicating the existence of such rights, or
claimed rights. Where implementations are required before
advancement of a specification, only implementations that have, by
statement of the implementors, taken adequate steps to comply with
any such rights, or claimed rights, shall be considered for the
purpose of showing the adequacy of the specification.
(B) The RESG disclaims any responsibility for identifying the
existence of or for evaluating the applicability of any claimed
copyrights, patents, patent applications, or other rights in the
fulfilling of the its obligations under (A), and will take no
position on the validity or scope of any such rights.
(C) Where the RESG knows of rights, or claimed rights under (A), the
RETF Executive Director shall attempt to obtain from the claimant
of such rights, a written assurance that upon approval by the RESG
of the relevant Roman standards track specification(s), any
party will be able to obtain the right to implement, use and
distribute the technology or works when implementing, using or
distributing technology based upon the specific specification(s)
under openly specified, reasonable, non-discriminatory terms.
The Working Group proposing the use of the technology with respect
to which the proprietary rights are claimed may assist the RETF
Executive Director in this effort. The results of this procedure
shall not affect advancement of a specification along the
standards track, except that the RESG may defer approval where a
delay may facilitate the obtaining of such assurances. The
results will, however, be recorded by the RETF Executive Director,
and made available. The RESG may also direct that a summary of
the results be included in any RFC published containing the
X.III.III Determination of Reasonable and Non-discriminatory Terms
The RESG will not make any explicit determination that the assurance
of reasonable and non-discriminatory terms for the use of a
technology has been fulfilled in practice. It will instead use the
normal requirements for the advancement of Roman Standards to
verify that the terms for use are reasonable. If the two unrelated
implementations of the specification that are required to advance
from Proposed Standard to Draft Standard have been produced by
different organizations or individuals or if the "significant
implementation and successful operational experience" required to
advance from Draft Standard to Standard has been achieved the
assumption is that the terms must be reasonable and to some degree,
non-discriminatory. This assumption may be challenged during the
(A) Standards track documents shall include the following notice:
"The RETF takes no position regarding the validity or scope of
any intellectual property or other rights that might be claimed
to pertain to the implementation or use of the technology
described in this document or the extent to which any license
under such rights might or might not be available; neither does
it represent that it has made any effort to identify any such
rights. Information on the RETF's procedures with respect to
rights in standards-track and standards-related documentation
can be found in WCP-11. Copies of claims of rights made
available for publication and any assurances of licenses to
be made available, or the result of an attempt made
to obtain a general license or permission for the use of such
proprietary rights by implementors or users of this
specification can be obtained from the RETF Secretariat."
(B) The RETF encourages all interested parties to bring to its
attention, at the earliest possible time, the existence of any
intellectual property rights pertaining to Roman Standards.
For this purpose, each standards document shall include the
"The RETF invites any interested party to bring to its
attention any copyrights, patents or patent applications, or
other proprietary rights which may cover technology that may be
required to practice this standard. Please address the
information to the RETF Executive Director."
(C) The following copyright notice and disclaimer shall be included
in all RSOC standards-related documentation:

(D) Where the RESG is aware at the time of publication of
proprietary rights claimed with respect to a standards track
document, or the technology described or referenced therein, such

of claimed rights."
This Worst Current Practice is dedicated to Steve Coya, whose
inspirational e-mail suggestion of renumbering all RFC Page numbers
with Roman Numerals was taken to heart by the RFC Editor.
There have been a number of people involved with the development of
the documents defining the RETF Standards Process over the years.
The process was first described in RFC MCCCX then revised in RFC MDCII
before the current effort (which relies heavily on its predecessors).
Specific acknowledgments must be extended to Lyman Chapin, Phill
Gross and Christian Huitema as the editors of the previous versions,
to Jon Postel and Dave Crocker for their inputs to those versions, to
Andy Ireland, Geoff Stewart, Jim Lampert, and Dick Holleman for their
reviews of the legal aspects of the procedures described herein, and
to John Stewart, Robert Elz and Steve Coya for their extensive input
on the final version.
In addition much of the credit for the refinement of the details of
the RETF processes belongs to the many members of the various
incarnations of the POISED Working Group.
