Sections 6.2 - 6.10 contain the lists of protocols in each stage of standardization. Finally are pointers to references and contacts for further information. This memo is intended to be issued approximately quarterly; please be sure the copy you are reading is current. Current copies may be obtained from the Network Information Center (INTERNIC) or from the Internet Assigned Numbers Authority (IANA) (see the contact information at the end of this memo). Do not use this edition after 16-Jun-97. See Section 6.1 for a description of recent changes. In the official lists in sections 6.2 - 6.10, an asterisk (*) next to a protocol denotes that it is new to this document or has been moved from one protocol level to another, or differs from the previous edition of this document. Internet Architecture Board Standards Track [Page 2] RFC 2000 Internet Standards February 1997 1. The Standardization Process The Internet Architecture Board maintains this list of documents that define standards for the Internet protocol suite. See RFC-1601 for the charter of the IAB and RFC-1160 for an explanation of the role and organization of the IAB and its subsidiary groups, the Internet Engineering Task Force (IETF) and the Internet Research Task Force (IRTF). Each of these groups has a steering group called the IESG and IRSG, respectively. The IETF develops these standards with the goal of co-ordinating the evolution of the Internet protocols; this co-ordination has become quite important as the Internet protocols are increasingly in general commercial use. The definitive description of the Internet standards process is found in RFC-1602. The majority of Internet protocol development and standardization activity takes place in the working groups of the IETF. Protocols which are to become standards in the Internet go through a series of states or maturity levels (proposed standard, draft standard, and standard) involving increasing amounts of scrutiny and testing. When a protocol completes this process it is assigned a STD number (see RFC-1311). At each step, the Internet Engineering Steering Group (IESG) of the IETF must make a recommendation for advancement of the protocol. To allow time for the Internet community to consider and react to standardization proposals, a minimum delay of 6 months before a proposed standard can be advanced to a draft standard and 4 months before a draft standard can be promoted to standard. It is general practice that no proposed standard can be promoted to draft standard without at least two independent implementations (and the recommendation of the IESG). Promotion from draft standard to standard generally requires operational experience and demonstrated interoperability of two or more implementations (and the recommendation of the IESG). In cases where there is uncertainty as to the proper decision concerning a protocol a special review committee may be appointed consisting of experts from the IETF, IRTF and the IAB with the purpose of recommending an explicit action. Advancement of a protocol to proposed standard is an important step since it marks a protocol as a candidate for eventual standardization (it puts the protocol "on the standards track"). Advancement to draft standard is a major step which warns the community that, unless major objections are raised or flaws are discovered, the protocol is likely to be advanced to standard in six months. Internet Architecture Board Standards Track [Page 3] RFC 2000 Internet Standards February 1997 Some protocols have been superseded by better ones or are otherwise unused. Such protocols are still documented in this memorandum with the designation "historic". Because it is useful to document the results of early protocol research and development work, some of the RFCs document protocols which are still in an experimental condition. The protocols are designated "experimental" in this memorandum. They appear in this report as a convenience to the community and not as evidence of their standardization. Other protocols, such as those developed by other standards organizations, or by particular vendors, may be of interest or may be recommended for use in the Internet. The specifications of such protocols may be published as RFCs for the convenience of the Internet community. These protocols are labeled "informational" in this memorandum. In addition to the working groups of the IETF, protocol development and experimentation may take place as a result of the work of the research groups of the Internet Research Task Force, or the work of other individuals interested in Internet protocol development. The the documentation of such experimental work in the RFC series is encouraged, but none of this work is considered to be on the track for standardization until the IESG has made a recommendation to advance the protocol to the proposed standard state. A few protocols have achieved widespread implementation without the approval of the IESG. For example, some vendor protocols have become very important to the Internet community even though they have not been recommended by the IESG. However, the IAB strongly recommends that the standards process be used in the evolution of the protocol suite to maximize interoperability (and to prevent incompatible protocol requirements from arising). The use of the terms "standard", "draft standard", and "proposed standard" are reserved in any RFC or other publication of Internet protocols to only those protocols which the IESG has approved. In addition to a state (like "Proposed Standard"), a protocol is also assigned a status, or requirement level, in this document. The possible requirement levels ("Required", "Recommended", "Elective", "Limited Use", and "Not Recommended") are defined in Section 4.2. When a protocol is on the standards track, that is in the proposed standard, draft standard, or standard state (see Section 5), the status shown in Section 6 is the current status. Few protocols are required to be implemented in all systems; this is because there is such a variety of possible systems, for example, Internet Architecture Board Standards Track [Page 4] RFC 2000 Internet Standards February 1997 gateways, routers, terminal servers, workstations, and multi-user hosts. The requirement level shown in this document is only a one word label, which may not be sufficient to characterize the implementation requirements for a protocol in all situations. For some protocols, this document contains an additional status paragraph (an applicability statement). In addition, more detailed status information may be contained in separate requirements documents (see Section 3). 2. The Request for Comments Documents The documents called Request for Comments (or RFCs) are the working notes of the "Network Working Group", that is the Internet research and development community. A document in this series may be on essentially any topic related to computer communication, and may be anything from a meeting report to the specification of a standard. Notice: All standards are published as RFCs, but not all RFCs specify standards. Anyone can submit a document for publication as an RFC. Submissions must be made via electronic mail to the RFC Editor (see the contact information at the end of this memo, and see RFC 1543). While RFCs are not refereed publications, they do receive technical review from the task forces, individual technical experts, or the RFC Editor, as appropriate. The RFC series comprises a wide range of documents, ranging from informational documents of general interests to specifications of standard Internet protocols. In cases where submission is intended to document a proposed standard, draft standard, or standard protocol, the RFC Editor will publish the document only with the approval of the IESG. For documents describing experimental work, the RFC Editor will notify the IESG before publication, allowing for the possibility of review by the relevant IETF working group or IRTF research group and provide those comments to the author. See Section 5.1 for more detail. Once a document is assigned an RFC number and published, that RFC is never revised or re-issued with the same number. There is never a question of having the most recent version of a particular RFC. However, a protocol (such as File Transfer Protocol (FTP)) may be improved and re-documented many times in several different RFCs. It is important to verify that you have the most recent RFC on a particular protocol. This "Internet Official Protocol Standards" Internet Architecture Board Standards Track [Page 5] RFC 2000 Internet Standards February 1997 memo is the reference for determining the correct RFC for the current specification of each protocol. The RFCs are available from the INTERNIC, and a number of other sites. For more information about obtaining RFCs, see Sections 7.4 and 7.5. 3. Other Reference Documents There are three other reference documents of interest in checking the current status of protocol specifications and standardization. These are the Assigned Numbers, the Gateway Requirements, and the Host Requirements. Note that these documents are revised and updated at different times; in case of differences between these documents, the most recent must prevail. Also, one should be aware of the MIL-STD publications on IP, TCP, Telnet, FTP, and SMTP. These are described in Section 3.4. 3.1. Assigned Numbers The "Assigned Numbers" document lists the assigned values of the parameters used in the various protocols. For example, IP protocol codes, TCP port numbers, Telnet Option Codes, ARP hardware types, and Terminal Type names. Assigned Numbers was most recently issued as RFC-1700. 3.2. Requirements for IP Version 4 Routers This document reviews the specifications that apply to gateways and supplies guidance and clarification for any ambiguities. Requirements for IP Version 4 Routers is RFC-1812. 3.3. Host Requirements This pair of documents reviews and updates the specifications that apply to hosts, and it supplies guidance and clarification for any ambiguities. Host Requirements was issued as RFC-1122 and RFC-1123. 3.4. The MIL-STD Documents The DoD MIL-STD Internet specifications are out of date and have been discontinued. The DoD's Joint Technical Architecture (JTA) lists the current set of IETF STDs and RFCs that the DoD intends to use in all new and upgraded Command, Control, Communications, Computers, and Intelligence (C4I) acquisitions. A copy of the JTA can be obtained from http://www-jta.itsi.disa.mil. Internet Architecture Board Standards Track [Page 6] RFC 2000 Internet Standards February 1997 4. Explanation of Terms There are two independent categorization of protocols. The first is the "maturity level" or STATE of standardization, one of "standard", "draft standard", "proposed standard", "experimental", "informational" or "historic". The second is the "requirement level" or STATUS of this protocol, one of "required", "recommended", "elective", "limited use", or "not recommended". The status or requirement level is difficult to portray in a one word label. These status labels should be considered only as an indication, and a further description, or applicability statement, should be consulted. When a protocol is advanced to proposed standard or draft standard, it is labeled with a current status. At any given time a protocol occupies a cell of the following matrix. Protocols are likely to be in cells in about the following proportions (indicated by the relative number of Xs). A new protocol is most likely to start in the (proposed standard, elective) cell, or the (experimental, limited use) cell. S T A T U S Req Rec Ele Lim Not +-----+-----+-----+-----+-----+ Std | X | XXX | XXX | | | S +-----+-----+-----+-----+-----+ Draft | X | X | XXX | | | T +-----+-----+-----+-----+-----+ Prop | | X | XXX | | | A +-----+-----+-----+-----+-----+ Info | | | | | | T +-----+-----+-----+-----+-----+ Expr | | | | XXX | | E +-----+-----+-----+-----+-----+ Hist | | | | | XXX | +-----+-----+-----+-----+-----+ What is a "system"? Some protocols are particular to hosts and some to gateways; a few protocols are used in both. The definitions of the terms below will refer to a "system" which is either a host or a gateway (or both). It should be clear from the context of the particular protocol which types of systems are intended. Internet Architecture Board Standards Track [Page 7] RFC 2000 Internet Standards February 1997 4.1. Definitions of Protocol State Every protocol listed in this document is assigned to a "maturity level" or STATE of standardization: "standard", "draft standard", "proposed standard", "experimental", or "historic". 4.1.1. Standard Protocol The IESG has established this as an official standard protocol for the Internet. These protocols are assigned STD numbers (see RFC- 1311). These are separated into two groups: (1) IP protocol and above, protocols that apply to the whole Internet; and (2) network-specific protocols, generally specifications of how to do IP on particular types of networks. 4.1.2. Draft Standard Protocol The IESG is actively considering this protocol as a possible Standard Protocol. Substantial and widespread testing and comment are desired. Comments and test results should be submitted to the IESG. There is a possibility that changes will be made in a Draft Standard Protocol before it becomes a Standard Protocol. 4.1.3. Proposed Standard Protocol These are protocol proposals that may be considered by the IESG for standardization in the future. Implementation and testing by several groups is desirable. Revision of the protocol specification is likely. 4.1.4. Experimental Protocol A system should not implement an experimental protocol unless it is participating in the experiment and has coordinated its use of the protocol with the developer of the protocol. Typically, experimental protocols are those that are developed as part of an ongoing research project not related to an operational service offering. While they may be proposed as a service protocol at a later stage, and thus become proposed standard, draft standard, and then standard protocols, the designation of a protocol as experimental may sometimes be meant to suggest that the protocol, although perhaps mature, is not intended for operational use. Internet Architecture Board Standards Track [Page 8] RFC 2000 Internet Standards February 1997 4.1.5. Informational Protocol Protocols developed by other standard organizations, or vendors, or that are for other reasons outside the purview of the IESG, may be published as RFCs for the convenience of the Internet community as informational protocols. 4.1.6. Historic Protocol These are protocols that are unlikely to ever become standards in the Internet either because they have been superseded by later developments or due to lack of interest. 4.2. Definitions of Protocol Status This document lists a "requirement level" or STATUS for each protocol. The status is one of "required", "recommended", "elective", "limited use", or "not recommended". 4.2.1. Required Protocol A system must implement the required protocols. 4.2.2. Recommended Protocol A system should implement the recommended protocols. 4.2.3. Elective Protocol A system may or may not implement an elective protocol. The general notion is that if you are going to do something like this, you must do exactly this. There may be several elective protocols in a general area, for example, there are several electronic mail protocols, and several routing protocols. 4.2.4. Limited Use Protocol These protocols are for use in limited circumstances. This may be because of their experimental state, specialized nature, limited functionality, or historic state. 4.2.5. Not Recommended Protocol These protocols are not recommended for general use. This may be because of their limited functionality, specialized nature, or experimental or historic state. Internet Architecture Board Standards Track [Page 9] RFC 2000 Internet Standards February 1997 5. The Standards Track This section discusses in more detail the procedures used by the RFC Editor and the IESG in making decisions about the labeling and publishing of protocols as standards. 5.1. The RFC Processing Decision Table Here is the current decision table for processing submissions by the RFC Editor. The processing depends on who submitted it, and the status they want it to have. +==========================================================+ |**************| S O U R C E | +==========================================================+ | Desired | IAB | IESG | IRSG | Other | | Status | | | | | +==========================================================+ | | | | | | | Standard | Bogus | Publish | Bogus | Bogus | | or | (2) | (1) | (2) | (2) | | Draft | | | | | | Standard | | | | | +--------------+----------+----------+----------+----------+ | | | | | | | | Refer | Publish | Refer | Refer | | Proposed | (3) | (1) | (3) | (3) | | Standard | | | | | | | | | | | +--------------+----------+----------+----------+----------+ | | | | | | | | Notify | Publish | Notify | Notify | | Experimental | (4) | (1) | (4) | (4) | | Protocol | | | | | | | | | | | +--------------+----------+----------+----------+----------+ | | | | | | | Information | Publish | Publish |Discretion|Discretion| | or Opinion | (1) | (1) | (5) | (5) | | Paper | | | | | | | | | | | +==========================================================+ (1) Publish. (2) Bogus. Inform the source of the rules. RFCs specifying Standard, or Draft Standard must come from the IESG, only. Internet Architecture Board Standards Track [Page 10] RFC 2000 Internet Standards February 1997 (3) Refer to an Area Director for review by a WG. Expect to see the document again only after approval by the IESG. (4) Notify both the IESG and IRSG. If no concerns are raised in two weeks then do Discretion (5), else RFC Editor to resolve the concerns or do Refer (3). (5) RFC Editor's discretion. The RFC Editor decides if a review is needed and if so by whom. RFC Editor decides to publish or not. Of course, in all cases the RFC Editor can request or make minor changes for style, format, and presentation purposes. The IESG has designated the IESG Secretary as its agent for forwarding documents with IESG approval and for registering concerns in response to notifications (4) to the RFC Editor. Documents from Area Directors or Working Group Chairs may be considered in the same way as documents from "other". 5.2. The Standards Track Diagram There is a part of the STATUS and STATE categorization that is called the standards track. Actually, only the changes of state are significant to the progression along the standards track, though the status assignments may change as well. The states illustrated by single line boxes are temporary states, those illustrated by double line boxes are long term states. A protocol will normally be expected to remain in a temporary state for several months (minimum six months for proposed standard, minimum four months for draft standard). A protocol may be in a long term state for many years. A protocol may enter the standards track only on the recommendation of the IESG; and may move from one state to another along the track only on the recommendation of the IESG. That is, it takes action by the IESG to either start a protocol on the track or to move it along. Generally, as the protocol enters the standards track a decision is made as to the eventual STATUS, requirement level or applicability (elective, recommended, or required) the protocol will have, although a somewhat less stringent current status may be assigned, and it then is placed in the the proposed standard STATE with that status. So the initial placement of a protocol is into state 1. At any time the STATUS decision may be revisited. Internet Architecture Board Standards Track [Page 11] RFC 2000 Internet Standards February 1997 | +<----------------------------------------------+ | ^ V 0 | 4 +-----------+ +===========+ | enter |-->----------------+-------------->|experiment | +-----------+ | +=====+=====+ | | V 1 | +-----------+ V | proposed |-------------->+ +--->+-----+-----+ | | | | | V 2 | +<---+-----+-----+ V | draft std |-------------->+ +--->+-----+-----+ | | | | | V 3 | +<---+=====+=====+ V | standard |-------------->+ +=====+=====+ | | V 5 +=====+=====+ | historic | +===========+ The transition from proposed standard (1) to draft standard (2) can only be by action of the IESG and only after the protocol has been proposed standard (1) for at least six months. The transition from draft standard (2) to standard (3) can only be by action of the IESG and only after the protocol has been draft standard (2) for at least four months. Occasionally, the decision may be that the protocol is not ready for standardization and will be assigned to the experimental state (4). This is off the standards track, and the protocol may be resubmitted to enter the standards track after further work. There are other paths into the experimental and historic states that do not involve IESG action. Sometimes one protocol is replaced by another and thus becomes historic, or it may happen that a protocol on the standards track is in a sense overtaken by another protocol (or other events) and becomes historic (state 5).

The host interface has been standardized in RFC-1112; however, multicast-routing gateways are in the experimental stage and are not widely available. An Internet host should support all of RFC-1112, except for the IGMP protocol itself which is optional; see RFC-1122 for more details. Even without IGMP, implementation of RFC-1112 will provide an important advance: IP-layer access to local network multicast addressing. It is expected that IGMP will become recommended for all hosts and gateways at some future date. SMI, MIB-II SNMP -- The Internet Architecture Board recommends that all IP and TCP implementations be network manageable. At the current time, this implies implementation of the Internet MIB-II (RFC-1213), and at least the recommended management protocol SNMP (RFC-1157). RIP -- The Routing Information Protocol (RIP) is widely implemented and used in the Internet. However, both implementors and users should be aware that RIP has some serious technical limitations as a routing protocol. The IETF is currently devpeloping several candidates for a new standard "open" routing protocol with better properties than RIP. The IAB urges the Internet community to track these developments, and to implement the new protocol when it is standardized; improved Internet service will result for many users. TP-TCP -- As OSI protocols become more widely implemented and used, there will be an increasing need to support interoperation with the TCP/IP protocols. The Internet Engineering Task Force is formulating strategies for interoperation. RFC-1006 provides one interoperation mode, in which TCP/IP is used to emulate TP0 in order to support OSI applications. Hosts that wish to run OSI connection-oriented applications in this mode should use the procedure described in RFC- 1006. In the future, the IAB expects that a major portion of the Internet will support both TCP/IP and OSI (inter-)network protocols in parallel, and it will then be possible to run OSI applications across the Internet using full OSI protocol "stacks".

Obsolete Protocols Some of the protocols listed in this memo are described in RFCs that are obsoleted by newer RFCs. "Obsolete" or "obsoleted" is not an official state or status of protocols. This subsection is for information only. While it may seem to be obviously wrong to have an obsoleted RFC in the list of standards, there may be cases when an older standard is in the process of being replaced. This process may take a year or two. Many obsoleted protocols are of little interest and are dropped from this memo altogether. Some obsoleted protocols have received enough recognition that it seems appropriate to list them under their current status and with the following reference to their current replacement.
