Introduction ๐ŸŒธ

okay so the intro basically tells you the plan ๐Ÿ—บ๏ธ first comes the standardization process and the RFC document series, then the terms get explained. Sections 6.2 - 6.9 hold the lists of protocols at each stage of standardization ๐Ÿ“‹ and last but not least, you get pointers to references and contacts for more info ๐Ÿฆ‹

this memo is meant to be issued quarterly, so double-check that the copy you're reading is current ๐Ÿ™ˆ you can grab current copies from the Network Information Center or the Internet Assigned Numbers Authority (check the contact info at the end of this memo). do not use this edition after 31-July-92 ๐Ÿ’€ that's a hard stop, bestie.

see Section 6.1 for a description of recent changes ๐Ÿ’– in the official lists in sections 6.2 - 6.9, a (*) next to a protocol means it's new to this document, got moved from one protocol level to another, or differs from the previous edition of this doc ๐Ÿ”ฅ

1. The Standardization Process ๐Ÿ’…

the Internet Activities Board keeps this list of documents that define standards for the Internet protocol suite ๐Ÿงฉ (see RFC-1160 for the role and organization of the IAB and its subsidiary groups, the Internet Engineering Task Force (IETF) and the Internet Research Task Force (IRTF)). the IAB sets these standards to co-ordinate how the Internet protocols evolve, and this co-ordination has become quite 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“–

most Internet protocol development and standardization happens in the working groups of the Internet Engineering Task Force ๐Ÿ› ๏ธ

protocols that are going to become Internet standards 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 a STD number (see RFC-1311) ๐Ÿ… at each step, the Internet Engineering Steering Group (IESG) of the IETF has to make a recommendation for advancing the protocol, and the IAB has to ratify it. if a recommendation isn't ratified, the protocol gets sent back to the IETF for more work ๐Ÿ”„

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) ๐Ÿง‘โ€๐Ÿ’ป promotion from draft standard to standard generally requires operational experience and demonstrated interoperability of two or more implementations (and the recommendation of the IESG) ๐Ÿค

if it's unclear what the right decision is for a protocol, the IAB may convene a special review committee made up of experts from the IETF, IRTF and the 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, because it marks the protocol as a candidate for eventual standardization (it puts the protocol "on the standards track") โœจ advancing to draft standard is a major step that 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 memo, labeled "historic" ๐Ÿ•ฐ๏ธ

because the IAB thinks it's useful to document the results of early protocol research and development, some RFCs document protocols that are still experimental ๐Ÿงช those protocols are designated "experimental" in this memo. they show up in this report as a convenience to the community, not as evidence that they've been standardized ๐Ÿ™…โ€โ™€๏ธ

other protocols, like ones developed by other standards organizations or particular vendors, may be interesting or may be recommended for use on the Internet ๐Ÿ“š their specifications may be published as RFCs for the community's convenience. these get labeled "informational" in this memo ๐Ÿท๏ธ

on top of the IETF working groups, protocol development and experimentation can also happen through the research groups of the Internet Research Task Force, or through other individuals interested in Internet protocol development ๐Ÿง  the IAB encourages documenting this experimental work in the RFC series, but none of it counts as being on the track for standardization until the IESG has recommended advancing the protocol to the proposed standard state and the IAB has approved that step ๐Ÿšฆ

a few protocols have achieved widespread implementation without approval from the IESG and the IAB. for example, some vendor protocols have become super important to the Internet community even though the IESG hasn't recommended them and the IAB hasn't ratified them ๐Ÿ˜ค still, the IAB strongly recommends using the IAB standards process to evolve the protocol suite, to maximize interoperability (and to prevent incompatible protocol requirements from showing up) ๐Ÿ’œ 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. no touching those words unless you've got the stamp ๐Ÿ™…โ€โ™€๏ธ

in addition to a state (like "Proposed Standard"), a protocol also gets a status, or requirement level, in this document ๐ŸŽš๏ธ 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 one. for a proposed or draft standard, though, the IAB will also endeavor to indicate the eventual status the protocol will have once it's adopted as a standard ๐Ÿ”ฎ

okay real talk: few protocols are required to be implemented in all systems, because there's such a huge 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 ๐Ÿ™ˆ for some protocols, this document has an extra status paragraph (an applicability statement). more detailed status info lives in separate requirements documents (see Section 3) ๐Ÿ“‘

2. The Request for Comments Documents ๐Ÿ“œ

Okay bestie, RFCs (Request for Comments) are basically the working notes of the "Network Working Group," which is the Internet research and development community ๐Ÿงšโœจ A doc in this series can be about literally any computer communication topic, from a meeting report all the way up to the spec for a standard ๐Ÿ’…

Notice: All standards are published as RFCs, but not all RFCs specify standards.

Anyone can submit a document for publication as an RFC ๐ŸŽ€ Submissions must be made via electronic mail to the RFC Editor (check 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. ๐Ÿค“

The RFC series is a whole mix of stuff, from informational docs of general interest to specs for standard Internet protocols ๐ŸŒˆ If a submission is meant to document a proposed standard, draft standard, or standard protocol, the RFC Editor will publish it only with the approval of both the IESG and the IAB. For docs describing experimental work, the RFC Editor will notify the IESG before publication. That gives the relevant IETF working group or IRTF research group a chance to review it and pass their comments on to the author. See Section 5.1 for more detail.

Once a doc is assigned an RFC number and published, that RFC is never revised or re-issued with the same number. So there is never a question of having the most recent version of a particular RFC ๐Ÿฆ‹ BUT a protocol (like File Transfer Protocol (FTP)) can get improved and re-documented many times across several different RFCs, so it's important to verify that you have the most recent RFC on a particular protocol ๐Ÿ‘€ The "IAB Official Protocol Standards" memo is the reference for figuring out the correct RFC for the current specification of each protocol.

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


3. Other Reference Documents ๐Ÿ”

There are three other reference docs worth checking when you want the current status of protocol specs and standardization. Those are the Assigned Numbers, the Gateway Requirements, and the Host Requirements. These docs get revised and updated at different times, so if they ever disagree, the most recent one prevails ๐Ÿ’–

Also, you should be aware of the MIL-STD publications on IP, TCP, Telnet, FTP, and SMTP. Those are 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. Think IP protocol codes, TCP port numbers, Telnet Option Codes, ARP hardware types, and Terminal Type names โœจ Assigned Numbers was most recently issued as RFC-1060.

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

3.2. Gateway Requirements ๐Ÿšช

This doc reviews the specs that apply to gateways and gives guidance and clarification for any ambiguities ๐Ÿ’… Gateway Requirements is RFC-1009, and a working group of the IETF is actively preparing a revision.

3.3. Host Requirements ๐Ÿ–ฅ๏ธ

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

3.4. The MIL-STD Documents ๐ŸŽ–๏ธ

The Internet community specs for IP (RFC-791) and TCP (RFC-793) and the DoD MIL-STD specs are meant to describe exactly the same protocols. Any difference in the protocols specified by these sets of docs should be reported to DCA and to the IAB. The RFCs and the MIL-STDs for IP and TCP differ in style and level of detail, so it is strongly advised that the two sets be used together, along with RFC-1122 and RFC-1123. ๐Ÿง

The IAB and DoD MIL-STD specs for FTP, SMTP, and Telnet are essentially the same docs (RFCs 765, 821, 854). The MIL-STD versions have been edited slightly. Also note that the current Internet spec for FTP is RFC-959 (as modified by RFC-1123).

Real talk though, these MIL-STDs are now somewhat out of date ๐Ÿ’€ The Gateway Requirements (RFC-1009) and Host Requirements (RFC-1122, RFC-1123) take precedence over both earlier RFCs and the MIL-STDs.

       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 docs are available from the Naval Publications and Forms Center. You can request them by telephone, telegraph, or mail, but private industry is preferred to use form DD1425 if possible. These five docs are included in the 1985 DDN Protocol Handbook (available from the SRI Network Information Systems Center, see Section 7.6). ๐Ÿ“ฎ

4. Explanation of Terms ๐ŸŽ€

Okay so there are two independent ways to categorize protocols ๐ŸŒธ The first is the "maturity level" or STATE of standardization, which is one of "standard", "draft standard", "proposed standard", "experimental", "informational" or "historic". The second is the "requirement level" or STATUS of the protocol, which is one of "required", "recommended", "elective", "limited use", or "not recommended".

The status or requirement level is hard to capture in a one-word label, so treat these status labels only as an indication. For the full picture, check a further description or applicability statement ๐Ÿ”

When a protocol is advanced to proposed standard or draft standard, it gets labeled with a current status. When possible, the IAB also notes the status the protocol is expected to have when it reaches the standard state โœจ

At any given time a protocol sits in one cell of the matrix below. Protocols are likely to be in cells in about the proportions shown (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. ๐Ÿงš

                             S T A T U S
                     Req   Rec   Ele   Lim   Not
                   +-----+-----+-----+-----+-----+

       S           +-----+-----+-----+-----+-----+
           Draft   |  X  |  X  | XXX |     |     |

           Info    |     |  X  | XXX |  XX |  X  |
       T           +-----+-----+-----+-----+-----+
           Expr    |     |     |  X  | XXX |  XX |
       E           +-----+-----+-----+-----+-----+
           Hist    |     |     |     |  X  | XXX |
                   +-----+-----+-----+-----+-----+

What is a "system"?

Some protocols are particular to hosts, some are particular to gateways, and a few are used in both ๐Ÿ’… The definitions below refer to a "system," which is either a host or a gateway (or both). The context of the particular protocol should make it clear which types of systems are intended.

4.1. Definitions of Protocol State ๐ŸŒˆ

Every protocol listed in this document is assigned to a "maturity level" or STATE of standardization: "standard", "draft standard", "proposed standard", "experimental", or "historic" ๐Ÿ’œ

4.1.1. Standard Protocol ๐Ÿ‘‘

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, which are protocols that apply to the whole Internet; and (2) network-specific protocols, which are generally specs for how to do IP on particular types of networks ๐Ÿง 

4.1.2. Draft Standard Protocol ๐Ÿงช

The IAB is actively considering this protocol as a possible Standard Protocol. Substantial and widespread testing and comment are desired, and comments and test results should be submitted to the IAB. There's a possibility that changes will be made to a Draft Standard Protocol before it becomes a Standard Protocol ๐Ÿ™ˆ

4.1.3. Proposed Standard Protocol ๐ŸŒฑ

These are protocol proposals that may be considered by the IAB for standardization in the future. Implementation and testing by several groups is desirable, and revision of the protocol specification is likely โœจ

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. ๐Ÿšซ

Typically, experimental protocols are developed as part of an ongoing research project that isn't related to an operational service offering. They may be proposed as a service protocol at a later stage, and so become proposed standard, draft standard, and then standard protocols. But calling a protocol experimental can sometimes be meant to suggest that it's not intended for operational use, even if it's perhaps mature ๐Ÿคทโ€โ™€๏ธ

4.1.5. Informational Protocol ๐Ÿ“š

Protocols developed by other standards organizations, by vendors, or for other reasons outside the purview of the IAB may be published as RFCs for the convenience of the Internet community as informational protocols. In some cases, these protocols may also be recommended for use in the Internet by the IAB ๐ŸŒธ

4.1.6. Historic Protocol ๐Ÿ•ฐ๏ธ

These are protocols that are unlikely to ever become standards in the Internet, either because they've been superseded by later developments or because of lack of interest ๐Ÿฅ€

4.2. Definitions of Protocol Status ๐Ÿ’…

This document lists a "requirement level" or STATUS for each protocol. The status is one of "required", "recommended", "elective", "limited use", or "not recommended" ๐Ÿซถ

4.2.1. Required Protocol ๐Ÿ”ฅ

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 ๐Ÿ’–

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 ๐Ÿงš

These protocols are not recommended for general use. This may be because of their limited functionality, specialized nature, or experimental or historic state. ๐Ÿ’€

5. The Standards Track โœจ

Okay bestie, this part is all about how the RFC Editor and the IAB decide when a protocol gets labeled a standard and published as one. It's giving serious gatekeeping energy, and I'm obsessed ๐Ÿ’…

5.1. The RFC Processing Decision Table

Here's the current decision table for how the RFC Editor processes submissions ๐Ÿ“‹. What happens depends on two things: who submitted it, and what status they want it to have.

Now let's decode the notes, because these are the important bits ๐ŸŽ€

  • (1) Publish. Straight to publication, no drama ๐ŸŒธ
  • (2) Bogus. Tell the source about the rules. RFCs specifying Standard, or Draft Standard, must come from the IAB, only ๐Ÿ™…โ€โ™€๏ธ
  • (3) Vote by the IAB. If it's approved, do Publish (1). If not, do Refer (4) ๐Ÿ—ณ๏ธ
  • (4) Refer to an Area Director for review by a WG. You won't see the document again until it's been approved by the IESG and the IAB ๐Ÿ”
  • (5) Notify both the IESG and IRSG. If nobody raises concerns in two weeks, do Discretion (6). If they do, the RFC Editor resolves the concerns or does Refer (4) ๐Ÿ“ฃ
  • (6) RFC Editor's discretion. The RFC Editor decides whether a review is needed and, if so, by whom. The RFC Editor also decides whether to publish or not ๐Ÿ‘‘

Of course, in every case the RFC Editor can request or make minor changes for style, format, and presentation purposes โœจ

The IESG has picked the IESG Secretary as its agent for forwarding documents with IESG approval, and for sending concerns from notifications (5) over to the RFC Editor ๐Ÿ’Œ Documents from Area Directors or Working Group Chairs get handled the same way as documents from "other" ๐Ÿซถ

5.2. The Standards Track Diagram

Okay so 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 change too.

States drawn with single line boxes are temporary, and states drawn with double line boxes are long term ๐Ÿ“ฆ 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) โณ Meanwhile, a protocol in a long term state can chill there for many years ๐Ÿ›‹๏ธ

Here's the wild part: a protocol can enter the standards track only on the recommendation of the IESG and by action of the IAB. It can also move from one state to another along the track only on the recommendation of the IESG and by action of the IAB. So it takes both the IESG and the IAB to either start a protocol on the track or move it along ๐Ÿค

When a protocol enters the standards track, a decision gets made about its eventual STATUS, requirement level or applicability (elective, recommended, or required). A somewhat less stringent current status might be assigned, and then it gets placed in the proposed standard STATE with that status โœจ So the initial placement of a protocol is into state 1. And at any time, the STATUS decision may be revisited ๐Ÿ”„

The move 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 move 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 ๐Ÿ†

Sometimes the verdict is that a protocol isn't ready for standardization. Then it gets assigned to the experimental state (4) ๐Ÿงช This is off the standards track, but the protocol can be resubmitted to enter the standards track after more work. There are other paths into the experimental and historic states that don't involve IAB action ๐Ÿšช

Also, one protocol can get replaced by another and become historic. Or a protocol on the standards track can get overtaken by another protocol (or other events) and become historic (state 5) ๐Ÿฅ€ Rough, but that's how it goes ๐Ÿ’€

Applicability Statements:

Okay so IGMP is giving "coming soon" energy ๐Ÿฆ‹ The Internet Activities Board is really trying to move toward general adoption of IP multicasting, because it's a more efficient move than broadcasting for lots of apps ๐Ÿ’– The host interface got standardized in RFC-1112 โœจ, however multicast-routing gateways are still in the experimental stage and aren't widely available ๐Ÿ™ˆ An Internet host should support all of RFC-1112, except for the IGMP protocol itself, which is optional ๐ŸŒธ see RFC-1122 for more details. Even without IGMP, implementing RFC-1112 is a huge glow-up: IP-layer access to local network multicast addressing ๐Ÿ’œ It is expected that IGMP will become recommended for all hosts and gateways at some future date ๐Ÿ‘‘

SMI, MIB-II SNMP -- The Internet Activities Board recommends that all IP and TCP implementations be network manageable ๐ŸŽ€ Right now that means implementing the Internet MIB-II (RFC-1213), and at least the recommended management protocol SNMP (RFC-1157) ๐Ÿงš

[Note: an asterisk at the end of a line indicates a change from the previous edition of this document.]

Applicability Statements:

RIP -- The Routing Information Protocol (RIP) is widely implemented and used across the Internet ๐Ÿ’– However, both implementors and users should be aware that RIP has some serious technical limitations as a routing protocol ๐Ÿ˜ญ The IETF is currently developing several candidates for a new standard "open" routing protocol with better properties than RIP โœจ 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 ๐Ÿ‘‘

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 ๐Ÿฆ‹ 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 ๐Ÿงš 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" ๐ŸŒˆ

PPP -- Point to Point Protocol is a method of sending IP over serial lines, which are a type of physical network ๐ŸŽ€ It is anticipated that PPP will be advanced to the network-specific standard protocol state in the future ๐Ÿ’œ
