RFC 2551               Roman Standards Process           I April MCMXCIXI.  INTRODUCTION   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   protocol itself.   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   Roman community.Bradner                 Worst Current Practice                [Page III]

RFC 2551               Roman Standards Process           I April MCMXCIX   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   o  timeliness.   The procedures described in this document are designed to be fair,   open, and objective;  to reflect existing (proven) practice;  and to   be flexible.   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      on-line directories.   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.Bradner                 Worst Current Practice                 [Page IV]

RFC 2551               Roman Standards Process           I April MCMXCIX   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.Bradner                 Worst Current Practice                  [Page V]

Roman STANDARDS-RELATED PUBLICATIONSII.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 (seeAppendix 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.Bradner                 Worst Current Practice                 [Page VI]

RFC 2551               Roman Standards Process           I April MCMXCIX   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.

(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).Bradner                 Worst Current Practice                [Page VII]

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.                                *      *                                                      *      ********************************************************Bradner                 Worst Current Practice               [Page VIII]

RFC 2551               Roman Standards Process           I April MCMXCIX   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   Standards).   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   III.III).Bradner                 Worst Current Practice                 [Page IX]

RFC 2551               Roman Standards Process           I April MCMXCIX   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.Bradner                 Worst Current Practice                  [Page X]

RFC 2551               Roman Standards Process           I April MCMXCIX      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      these TSs:   (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      status.   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   section VI.   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 RomanBradner                 Worst Current Practice                 [Page XI]

RFC 2551               Roman Standards Process           I April MCMXCIX   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"   level.   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   designation.   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   Roman.   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.Bradner                 Worst Current Practice                [Page XII]

RFC 2551               Roman Standards Process           I April MCMXCIX   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   environments.Bradner                 Worst Current Practice               [Page XIII]

RFC 2551               Roman Standards Process           I April MCMXCIX   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   environment.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   community.   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.IV.II.I  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 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.Bradner                 Worst Current Practice                [Page XIV]

RFC 2551               Roman Standards Process           I April MCMXCIXIV.II.II  Informational   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 ofsection 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   RFCs.   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 proposesBradner                 Worst Current Practice                 [Page XV]

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.IV.II.IV  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 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 entitiesBradner                 Worst Current Practice                [Page XVI]

RFC 2551               Roman Standards Process           I April MCMXCIX   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   immediate instantiation.   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   RETF.   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.Bradner                 Worst Current Practice               [Page XVII]

RFC 2551               Roman Standards Process           I April MCMXCIXVI.  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   the RESG.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 impactBradner                 Worst Current Practice              [Page XVIII]

RFC 2551               Roman Standards Process           I April MCMXCIX   on Rome or on the suite of Roman protocols, the RESG may,   at its discretion, commission an independent technical review of the   specification.   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.VI.I.III  Publication   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.Bradner                 Worst Current Practice                [Page XIX]

RFC 2551               Roman Standards Process           I April MCMXCIX   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   actions.   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   track.   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   action.   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 functionBradner                 Worst Current Practice                 [Page XX]

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   time-at-level clock.   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   interested party.Bradner                 Worst Current Practice                [Page XXI]

RFC 2551               Roman Standards Process           I April MCMXCIXVI.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.Bradner                 Worst Current Practice               [Page XXII]

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.

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   their decision.   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   reached.]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   specifications.   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.

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      it.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   online.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".Bradner                 Worst Current Practice                [Page XXV]

This is acceptable if (I)   the specification is provided to the Working Group in compliance with   the requirements ofsection 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   specification.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.

It replaces a previous version, and in time, is likely itself to   be replaced.   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   below.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 itBradner                 Worst Current Practice              [Page XXVII]

RFC 2551               Roman Standards Process           I April MCMXCIX   determines appropriate to protect the interests of the Roman   community.   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   process.   The appeals process in section VI.V applies to this process.IX.II Exclusions   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 RIGHTSX.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.Bradner                 Worst Current Practice             [Page XXVIII]

RFC 2551               Roman Standards Process           I April MCMXCIXX.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).Bradner                 Worst Current Practice               [Page XXIX]

RFC 2551               Roman Standards Process           I April MCMXCIX  IV. The contributor represents that contribution properly acknowledge      major contributors.   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      contributor.      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.Bradner                 Worst Current Practice                [Page XXX]

RFC 2551               Roman Standards Process           I April MCMXCIX   (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      specification.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   Last-Call period.X.IV.  Notices   (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.

(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      following invitation:         "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."

ACKNOWLEDGMENTS   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.XII.
