IAB OFFICIAL PROTOCOL STANDARDS ๐ŸŽ€

Bestie, this is RFC 1360, and it's basically the Internet Architecture Board's official list of Internet protocol standards ๐Ÿ‘‘. J. Postel, Editor wrote it, and the Internet Architecture Board is the group behind it. It came out in September 1992, and it's the STD: 1 document ๐Ÿ”ฅ. It obsoletes RFCs 1280, 1250, 1100, 1083, 1130, 1140, 1200, so those are retired now ๐Ÿ’€. Nothing is listed as updated.

Status of this Memo

Okay so this memo describes where the standardization of Internet protocols stands, as decided by the Internet Architecture Board (IAB) ๐Ÿ“‹. Distribution is unlimited, so share it with your whole group chat ๐Ÿ’œ.

Introduction โœจ

The vibe of this doc goes like this: first comes the standardization process and the RFC document series, then the explanation of terms ๐Ÿ’…. Sections 6.2 - 6.9 are the lists of protocols at each stage of standardization ๐Ÿ“. Last but not least, you get pointers to references and contacts for more info ๐Ÿงš.

This memo is meant to come out about quarterly, so make sure the copy you're reading is current ๐ŸŒธ. Current copies can be grabbed from the Network Information Center or from the Internet Assigned Numbers Authority (check the contact info at the end of this memo) ๐Ÿฆ‹.

Do not use this edition after 15-Jan-93. Bestie, that date is long gone ๐Ÿ’€

See Section 6.1 for the recent changes ๐Ÿ‘€. In the official lists in sections 6.2 - 6.9, an asterisk * next to a protocol means it's new to this document, has been moved from one protocol level to another, or differs from the previous edition of this document โญ.

1. The Standardization Process ๐Ÿ’–

The Internet Architecture Board keeps this list of documents that define standards for the Internet protocol suite ๐Ÿ“œ. See RFC-1358 for the IAB charter, and RFC-1160 for how the IAB and its subsidiary groups are organized: the Internet Engineering Task Force (IETF) and the Internet Research Task Force (IRTF). Each of those has a steering group, called the IESG and IRSG respectively. The IAB provides these standards with the goal of co-ordinating how the Internet protocols evolve, and that co-ordination has gotten super important now that the protocols are increasingly in general commercial use ๐Ÿ’ผ. The definitive description of the Internet standards process is in RFC-1310 ๐Ÿ“–.

The majority of Internet protocol development and standardization happens in the working groups of the Internet Engineering Task Force ๐Ÿซถ.

Protocols that are going to become standards on the Internet move through a series of states or maturity levels (proposed standard, draft standard, and standard), with more and more scrutiny and testing at each step ๐Ÿ”. Once a protocol finishes this process, it gets assigned an STD number (see RFC-1311) ๐Ÿ†. At each step, the Internet Engineering Steering Group (IESG) of the IETF must make a recommendation for advancement, and the IAB must ratify it. If a recommendation isn't ratified, the protocol gets remanded to the IETF for more work ๐Ÿ˜ค.

To give the Internet community time to think about and react to standardization proposals, the IAB imposes 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 โณ.

It's general IAB practice that no proposed standard gets 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) ๐Ÿงช.

If it's unclear what the right decision is about a protocol, the IAB may convene a special review committee made up of experts from the IETF, IRTF, and IAB, whose job is to recommend an explicit action to the IAB ๐Ÿ•ต๏ธโ€โ™€๏ธ.

Advancing a protocol to proposed standard is a big deal, since it marks the protocol as a candidate for eventual standardization (it puts the protocol "on the standards track") ๐Ÿ›ค๏ธ. Advancing to draft standard is a major step too, because it 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 ๐Ÿšจ.

Some protocols have been superseded by better ones or are otherwise unused. Those are still documented in this memorandum with the designation "historic" ๐Ÿ•ฐ๏ธ.

The IAB thinks it's useful to document the results of early protocol research and development, so some of the RFCs document protocols that are still experimental. These protocols are designated "experimental" in this memorandum. They appear here as a convenience to the community and not as evidence of their standardization ๐Ÿงช๐Ÿซง.

Other protocols, like those developed by other standards organizations or by particular vendors, may be of interest or may be recommended for use on the Internet. The specifications of those protocols may be published as RFCs for the convenience of the Internet community. These protocols are labeled "informational" in this memorandum ๐Ÿ“š.

Beyond the IETF working groups, protocol development and experimentation can also happen through the research groups of the Internet Research Task Force, or through the work of other individuals interested in Internet protocol development ๐Ÿง‘โ€๐Ÿ’ป. The IAB encourages documenting that experimental work in the RFC series, but none of it 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, and the IAB has approved this step ๐Ÿšฆ.

A few protocols have achieved widespread implementation without the approval of the IESG and the IAB. For example, some vendor protocols have become very important to the Internet community even though they have not been recommended by the IESG or ratified by the IAB. However, the IAB strongly recommends that the IAB standards process be used in the evolution of the protocol suite, to maximize interoperability and to prevent incompatible protocol requirements from arising ๐Ÿค. The IAB reserves the use of the terms "standard", "draft standard", and "proposed standard" in any RFC or other publication of Internet protocols for only those protocols the IAB has approved ๐Ÿ”’.

In addition to a state (like "Proposed Standard"), a protocol is also given a status, or requirement level, in this document ๐ŸŽฏ. 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, meaning it's in the proposed standard, draft standard, or standard state (see Section 5), the status shown in Section 6 is the current status. For a proposed or draft standard, though, the IAB will also endeavor to indicate the eventual status this protocol will have after it's adopted as a standard ๐Ÿ”ฎ.

Few protocols are required to be implemented in all systems, because there's such a variety of possible systems, like gateways, terminal servers, workstations, and multi-user hosts ๐Ÿ–ฅ๏ธ. The requirement level shown in this document is only a one-word label, which may not be enough to describe a protocol's implementation requirements in every situation. For some protocols, this document contains an additional status paragraph (an applicability statement). On top of that, more detailed status information lives in separate requirements documents (see Section 3) ๐ŸŒˆ.

2. The Request for Comments Documents โœจ

okay so RFCs (Request for Comments) are literally the working notes of the "Network Working Group", aka the Internet research and development community ๐Ÿง  A doc in this series can be about basically any computer communication topic ๐Ÿ’–, from a meeting report all the way up to a full-on standard ๐Ÿ”ฅ

Notice:

All standards are published as RFCs, but not all RFCs specify standards. ๐Ÿซถ

Anyone can submit a document for publication as an RFC ๐Ÿ’… Submissions MUST be made via electronic mail to the RFC Editor (see the contact information at the end of this memo, and see RFC 1111).

RFCs aren't refereed publications, but they do get technical review from the task forces, individual technical experts, or the RFC Editor, as appropriate ๐Ÿง

The RFC series is a whole range of docs, from informational stuff of general interest to specs for standard Internet protocols ๐ŸŒˆ When a submission is meant to document a proposed standard, draft standard, or standard protocol, the RFC Editor only publishes it with the approval of both the IESG and the IAB ๐Ÿ‘‘ For experimental work, the RFC Editor notifies the IESG before publication, which leaves room for the relevant IETF working group or IRTF research group to review it and send comments to the author ๐Ÿงช See Section 5.1 for more detail.

Once a doc gets an RFC number and is published, that RFC is never revised or re-issued with the same number ๐Ÿ”’ So there's never a question about having the most recent version of a particular RFC. BUT a protocol (like File Transfer Protocol (FTP)) can be improved and re-documented many times across several different RFCs ๐Ÿ”„ Lowkey important: verify you have the most recent RFC on a particular protocol. The "IAB Official Protocol Standards" memo is the reference for figuring out the correct RFC for the current spec of each protocol ๐Ÿ“Œ

The RFCs are available from the Network Information Center at SRI International, and a number of other sites. For more info on getting RFCs, see Sections 7.4 and 7.5 ๐Ÿ“š


3. Other Reference Documents ๐Ÿ“š

There are three other reference docs worth knowing about when you're checking the current status of protocol specs and standardization ๐Ÿ” They're the Assigned Numbers, the Gateway Requirements, and the Host Requirements. These get revised and updated at different times, so in case of differences between these documents, the most recent MUST prevail ๐Ÿ†

Also, be aware of the MIL-STD publications on IP, TCP, Telnet, FTP, and SMTP ๐ŸŽ€ They're described in Section 3.4.

3.1. Assigned Numbers ๐Ÿ”ข

This doc lists the assigned values of the parameters used in the various protocols: like IP protocol codes, TCP port numbers, Telnet Option Codes, ARP hardware types, and Terminal Type names ๐Ÿ’… Assigned Numbers was most recently issued as RFC-1340.

Another doc, Internet Numbers, lists the assigned IP network numbers and the autonomous system numbers ๐ŸŒ Internet Numbers was most recently issued as RFC-1166.

3.2. Gateway Requirements ๐Ÿšช

This doc reviews the specs that apply to gateways and supplies guidance and clarification for any ambiguities. Gateway Requirements is RFC-1009. A working group of the IETF is actively preparing a revision โœจ

3.3. Host Requirements ๐Ÿ–ฅ๏ธ

This pair of docs reviews and updates the specs that apply to hosts, and it supplies guidance and clarification for any ambiguities ๐Ÿ’œ Host Requirements was issued as RFC-1122 and RFC-1123.

3.4. The MIL-STD Documents ๐ŸŽฏ

The Internet community specs for IP (RFC-791) and TCP (RFC-793) and the DoD MIL-STD specs are intended to describe exactly the same protocols ๐Ÿ‘€ Any difference in the protocols specified by these sets of documents SHOULD be reported to DCA and to the IAB ๐Ÿ™ˆ The RFCs and the MIL-STDs for IP and TCP differ in style and level of detail. It is strongly advised that the two sets of documents be used together, along with RFC-1122 and RFC-1123 ๐Ÿซถ

The IAB and the DoD MIL-STD specs for the FTP, SMTP, and Telnet protocols are essentially the same documents (RFCs 765, 821, 854). The MIL-STD versions have been edited slightly. Note that the current Internet specification for FTP is RFC-959 (as modified by RFC-1123) โœ๏ธ

Note that these MIL-STD are now somewhat out of date. The Gateway Requirements (RFC-1009) and Host Requirements (RFC-1122, RFC-1123) take precedence over both earlier RFCs and the MIL-STDs ๐Ÿ‘‘

Internet Protocol (IP)                      MIL-STD-1777
Transmission Control Protocol (TCP)         MIL-STD-1778
File Transfer Protocol (FTP)                MIL-STD-1780
Simple Mail Transfer Protocol (SMTP)        MIL-STD-1781
Telnet Protocol and Options (TELNET)        MIL-STD-1782

These documents are available from the Naval Publications and Forms Center. Requests can be initiated by telephone, telegraph, or mail; however, it is preferred that private industry use form DD1425, if possible ๐Ÿ“ฎ

4. Explanation of Terms ๐Ÿง 

There are two independent categorizations of protocols ๐Ÿ’ซ 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 hard to squish into a one-word label ๐Ÿ˜… 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 and, when possible, the IAB also notes the status that the protocol is expected to have when it reaches the standard state ๐Ÿš€

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, not recommended) cell ๐Ÿฆ‹

                         S T A T U S
                 Req   Rec   Ele   Lim   Not

   T           +-----+-----+-----+-----+-----+
       Prop    |     |  X  | XXX |     |     |
   A           +-----+-----+-----+-----+-----+
       Info    |     |  X  | XXX |  XX |  X  |

               +-----+-----+-----+-----+-----+

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 ๐Ÿ’…

4.1. Definitions of Protocol State ๐ŸŒธ

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 โญ

The IAB has established this as an official standard protocol for the Internet. These protocols are assigned STD numbers (see RFC-1311). They're 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 ๐ŸŽ€

The IAB 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 IAB. 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 ๐ŸŒท

These are protocol proposals that MAY be considered by the IAB 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 ๐Ÿงช

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 ๐Ÿ”ฌ

4.1.5. Informational Protocol ๐Ÿ“–

Protocols developed by other standard organizations, or vendors, or that are for other reasons outside the purview of the IAB, MAY be published as RFCs for the convenience of the Internet community as informational protocols. Such protocols MAY in some cases also be recommended for use in the Internet by the IAB.

4.1.6. Historic Protocol ๐Ÿ•ฐ๏ธ

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 ๐Ÿ’€

4.2. Definitions of Protocol Status ๐ŸŽฏ

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 ๐Ÿ‘‘

A system MUST implement the required protocols.

A system SHOULD implement the recommended protocols.

4.2.3. Elective Protocol ๐Ÿฆ‹

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 ๐Ÿ”’

These protocols are for use in limited circumstances. This MAY be because of their experimental state, specialized nature, limited functionality, or historic state.

These protocols are not recommended for general use. This MAY be because of their limited functionality, specialized nature, or experimental or historic state.

5. The Standards Track โœจ

okay bestie, this section is all about how the RFC Editor and the IAB decide what gets labeled a standard and what gets published ๐Ÿง๐Ÿ’… it's giving paperwork, but make it a drama ๐ŸŽ€

5.1. The RFC Processing Decision Table

here's the current decision table for how the RFC Editor handles submissions ๐Ÿ’– the big thing is that it depends on WHO submitted it and what status they're asking for. no cap, that's the whole vibe ๐Ÿ˜ญ

here's what the numbers in the table mean ๐Ÿ”

  • (1) Publish.
  • (2) Bogus. Tell the source about the rules ๐Ÿ“ฃ and yes, RFCs specifying Standard, or Draft Standard must come from the IAB, only.
  • (3) Vote by the IAB. If it's approved, do Publish (1). If not, do Refer (4).
  • (4) Refer to an Area Director for review by a WG. The document only comes back to the RFC Editor after it's been approved by both the IESG and the IAB ๐Ÿ”
  • (5) Notify both the IESG and IRSG. If nobody raises concerns within two weeks, do Discretion (6). If they do, the RFC Editor resolves the concerns or does Refer (4) ๐Ÿ•ฐ๏ธ
  • (6) RFC Editor's discretion. The RFC Editor decides whether a review is needed and, if so, who does it. The RFC Editor also decides whether to publish or not ๐Ÿ‘‘

obvi, in every case the RFC Editor can ask for or make small tweaks for style, format, and presentation ๐Ÿ’…โœจ

the IESG made the IESG Secretary its agent ๐Ÿงš for two jobs: forwarding documents that already have IESG approval, and logging concerns raised in response to notifications (5) to the RFC Editor. documents from Area Directors or Working Group Chairs get handled the same way as documents from "other" ๐Ÿ’Œ

5.2. The Standards Track Diagram

there's a part of the STATUS and STATE categorization called the standards track ๐Ÿ›ค๏ธ honestly, only the changes of state really matter for moving along the track, though the status assignments can get changed too ๐Ÿฆ‹

on the diagram, single line boxes are temporary states and double line boxes are long term states. a protocol is normally expected to stay in a temporary state for several months (minimum six months for proposed standard, minimum four months for draft standard) ๐ŸŒธ a protocol can hang out in a long term state for many years ๐Ÿฅน

a protocol can only enter the standards track on the recommendation of the IESG and by action of the IAB ๐Ÿซถ and it can only move from one state to another along the track on the recommendation of the IESG and by action of the IAB too. so it takes both the IESG AND the IAB to either start a protocol on the track or move it along. no solo missions ๐Ÿค

when a protocol enters the standards track, a decision gets made about the eventual STATUS, requirement level, or applicability (elective, recommended, or required) it'll end up with. it can start with a somewhat less strict current status, and then it's placed in the proposed standard STATE with that status ๐Ÿ’– so the very first spot a protocol lands in is state 1. and the STATUS decision can be revisited at any time โœจ

the jump from proposed standard (1) to draft standard (2) can only happen by action of the IAB, on the recommendation of the IESG, and only after the protocol has been proposed standard (1) for at least six months ๐Ÿ•ฐ๏ธ

the jump from draft standard (2) to standard (3) can only happen by action of the IAB, on the recommendation of the IESG, and only after the protocol has been draft standard (2) for at least four months ๐ŸŽ‰

sometimes the verdict is that a protocol isn't ready for standardization yet ๐Ÿฅบ in that case it gets assigned to the experimental state (4). that's off the standards track, but the protocol can be resubmitted to get back on after more work ๐Ÿ’œ there are other ways into the experimental and historic states that don't involve IAB action, too ๐ŸŒˆ

and sometimes one protocol gets replaced by another and becomes historic ๐Ÿ›๏ธ or a protocol on the standards track gets kind of overtaken by another protocol (or by other events) and becomes historic (state 5). that's a whole glow-up in reverse ๐Ÿ’€

6.2. Standard Protocols ๐Ÿ’–

Applicability Statements: ๐ŸŽ€

IGMP ๐Ÿฆ‹ The IAB is totally aiming for general adoption of IP multicasting, because it's way more efficient than broadcasting for lots of apps ๐Ÿ’œ. The host interface got standardized in RFC-1112, BUT multicast-routing gateways are still experimental and not widely available yet ๐Ÿ™ˆ. An Internet host should support all of RFC-1112, except the IGMP protocol itself, which is optional (see RFC-1122 for more details) โœจ. Even without IGMP, RFC-1112 is a huge glow-up, because you get IP-layer access to local network multicast addressing ๐Ÿ‘‘. It is expected that IGMP will become recommended for all hosts and gateways at some future date ๐ŸŒˆ.

SMI, MIB-II SNMP ๐Ÿงš The IAB recommends that all IP and TCP implementations be network manageable. Right now that means implementing the Internet MIB-II (RFC-1213), plus at least the recommended management protocol SNMP (RFC-1157) ๐Ÿ’….


6.3. Network-Specific Standard Protocols ๐Ÿ”Œ

Here's the list, bestie ๐Ÿ’–:

Applicability Statements: โœจ

Okay so it's expected that a system will support one or more physical networks, and for each physical network it supports, the appropriate protocols from the list above must be supported ๐Ÿซถ. Basically, it's elective to support any particular type of physical network, but for the physical networks you actually do support, they are required to be supported exactly according to the protocols in the list above ๐Ÿ’…. Also, check out the Host and Gateway Requirements RFCs for more specific info on network-specific ("link layer") protocols ๐ŸŒธ.


6.4. Draft Standard Protocols ๐ŸŒธ

Applicability Statements: ๐Ÿ’œ

RIP ๐ŸŒ The Routing Information Protocol (RIP) is widely implemented and used across the Internet. However, both implementors and users should be aware that RIP has some serious technical limitations as a routing protocol ๐Ÿ’€. The IETF is currently developing 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, because improved Internet service will result for many users ๐Ÿซถ.

TP-TCP ๐Ÿฆ‹ As OSI protocols get more widely implemented and used, there's going to be an increasing need to support interoperation with the TCP/IP protocols. The Internet Engineering Task Force is working on 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 then it will be possible to run OSI applications across the Internet using full OSI protocol "stacks" ๐Ÿ‘‘.

PPP ๐Ÿงš Point to Point Protocol is a method of sending IP over serial lines, which are a type of physical network. It is anticipated that PPP will be advanced to the network-specifics standard protocol state in the future ๐ŸŒˆ.

The protocol standards are managed for the IAB by the Internet Assigned Numbers Authority. ๐Ÿฆ‹
