The Internet Activities Board maintains this list of documents that
define standards for the Internet protocol suite (see 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)). The IAB provides these
Internet Activities Board [Page 2]
RFC 1200 IAB Standards April 1991
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 majority of Internet protocol development and standardization
activity takes place in the working groups of the Internet
Engineering Task Force.
Protocols which are to become standards in the Internet go through a
series of states (proposed standard, draft standard, and standard)
involving increasing amounts of scrutiny and experimental testing.
At each step, the Internet Engineering Steering Group (IESG) of the
IETF must make a recommendation for advancement of the protocol and
the IAB must ratify it. If a recommendation is not ratified, the
protocol is remanded to the IETF for further work.
To allow time for the Internet community to consider and react to
standardization proposals, the IAB imposes a minimum delay of 4
months before a proposed standard can be advanced to a draft standard
and 6 months before a draft standard can be promoted to standard.
It is general IAB 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 the IAB may convene a special review committee
consisting of experts from the IETF, IRTF and the IAB with the
purpose of recommending an explicit action to the IAB.
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.
Some protocols have been superseded by better ones or are otherwise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 the IAB believes 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
Internet Activities Board [Page 3]
RFC 1200 IAB Standards April 1991
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
IAB encourages the documentation of such experimental work in the RFC
series, 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, and the IAB has approved
this step.
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). The IAB reserves the use of the terms "standard",
"draft standard", and "proposed standard" in any RFC or other
publication of Internet protocols to only those protocols which the
IAB 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. For a proposed or
draft standard, however, the IAB will also endeavor to indicate the
eventual status this protocol will have after adoption as a standard.
Few protocols are required to be implemented in all systems; this is
because there is such a variety of possible systems, for example,
gateways, 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,
Internet Activities Board [Page 4]
RFC 1200 IAB Standards April 1991
this document contains an additional status paragraph. In addition,
more detailed status information is contained in separate
requirements documents (see Section 3).
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).
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 both the IESG and the IAB. 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 "IAB Official Protocol Standards" memo is
the reference for determining 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 information
Internet Activities Board [Page 5]
RFC 1200 IAB Standards April 1991
about obtaining RFCs, see Sections 7.4 and 7.5.
There are four other reference documents of interest in checking the
current status of protocol specifications and standardization. These
are the Assigned Numbers, the Annotated Internet Protocols, 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 3.5.
This 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-1060.
Another document, Internet Numbers, lists the assigned IP network
numbers, and the autonomous system numbers. Internet Numbers was
most recently issued as RFC-1166.
This document reviews the specifications 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.
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.
Internet Activities Board [Page 6]
RFC 1200 IAB Standards April 1991
The Internet community specifications for IP (RFC-791) and TCP (RFC-
793) and the DoD MIL-STD specifications are intended to describe
exactly the same protocols. Any difference in the protocols
specified by these sets of documents 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. It is strongly advised that the two sets of
documents be used together, along with RFC-1122.
The IAB and the DoD MIL-STD specifications 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).
Internet Protocol (IP) MIL-STD-1777
Transmission Control Protocol (TCP) MIL-STD-1778
File Transfer Protocol (FTP) MIL-STD-1780

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. These five documents are included in the 1985 DDN Protocol
Handbook (available from the Network Information Center, see Section
7.4).

There are two independent categorization of protocols. The first is
the STATE of standardization, one of "standard", "draft standard",
"proposed standard", "experimental", "informational" or "historic".
The second is the 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.
Internet Activities Board [Page 7]
RFC 1200 IAB Standards April 1991
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.
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.

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.
Every protocol listed in this document is assigned to a STATE of
standardization: "standard", "draft standard", "proposed standard",
"experimental", or "historic".
4.1.1. Standard Protocol
The IAB has established this as an official standard protocol for
the Internet. 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.
Internet Activities Board [Page 8]
RFC 1200 IAB Standards April 1991
4.1.2. Draft Standard Protocol
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
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
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.
4.1.5. Informational Protocol
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
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.
Internet Activities Board [Page 9]
RFC 1200 IAB Standards April 1991
This document lists a 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.
This section discusses in more detail the procedures used by the RFC
Editor and the IAB in making decisions about the labeling and
publishing of protocols as standards.
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.

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 protest
in response to notifications (5) to the RFC Editor. Documents from
Area Directors or Working Group Chairs may be considered in the same
way as documents from "other".
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 be changed 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 four months for proposed standard, minimum
six 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 by action of the IAB; and may move from one state to
another along the track only on the recommendation of the IESG and by
action of the IAB. That is, it takes both the IESG and the IAB 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 (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.

The transition from proposed standard (1) to draft standard (2) can
only be by action of the IAB on the recommendation of the IESG and
only after the protocol has been proposed standard (1) for at least
four months.
The transition from draft standard (2) to standard (3) can only be by
action of the IAB on the recommendation of the IESG and only after
the protocol has been draft standard (2) for at least six 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
IAB action.
Sometimes one protocol is replaced by another and thus becomes
historic, 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).

Notes:
IGMP -- The Internet Activities Board intends to move towards general
adoption of IP multicasting, as a more efficient solution than
broadcasting for many applications. 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
Internet Activities Board [Page 22]
RFC 1200 IAB Standards April 1991
is expected that IGMP will become recommended for all hosts and
gateways at some future date.
SMI, MIB, SNMP -- The Internet Activities Board recommends that all
IP and TCP implementations be network manageable. At the current
time, this implies implementation of the Internet MIB (RFC-1156), the
MIB extension MIB-II (RFC-1158, a Draft Standard), and at least the
recommended management protocol SNMP (RFC-1157).

It is expected that a system will support one or more physical
networks and for each physical network supported the appropriate
protocols from the above list must be supported. That is, it is
elective to support any particular type of physical network, and for
the physical networks actually supported it is required that they be
supported exactly according to the protocols in the above list. See
also the Host and Gateway Requirements RFCs for more specific
information on network-specific ("link layer") protocols.

Notes:
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 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; 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".
MIB-II -- This memo defines a mandatory extension to the base MIB
(RFC-1156) and is a Draft Standard for the Internet community. The
extensions described here are currently Elective, but when they
become a standard, they will have the same status as RFC-1156, that
is, Recommended. See also the note on SMI, MIB and SNMP under
Standards.

PPP -- 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-specific standard protocol state
in the future.
