RFC 2500 Internet Standards June 1999
1. Introduction
This memo summarizes the status of Internet protocols and
specifications. It is published by the RFC Editor in accordance with
Section 2.1 of "The Internet Standards Process -- Revision 3", RFC
2026, which specifies the rules and procedures by which all Internet
stnadards are set. This memo is prepared by the RFC Editor for the
IESG and IAB. It is a member of a series of summary memos that are
published approximately every one hundred RFCs; please see
www.rfc-editor.org.
This memo lists the level and status of the archival documents known
as RFCs (Request for Comments) within the Internet standards process.
The reader is urged to review RFC 2026 for essential context for
interpreting this memo.
The following introductory text is quoted directly from RFC 2026:
"The Internet, a loosely-organized international collaboration of
autonomous, interconnected networks, supports host-to-host
communication through voluntary adherence to open protocols and
procedures defined by Internet Standards. There are also many
isolated interconnected networks, which are not connected to the
global Internet but use the Internet Standards.
The Internet Standards Process described in this document is
concerned with all protocols, procedures, and conventions that are
used in or by the Internet, whether or not they are part of the
TCP/IP protocol suite. In the case of protocols developed and/or
standardized by non-Internet organizations, however, the Internet
Standards Process normally applies to the application of the
protocol or procedure in the Internet context, not to the
specification of the protocol itself.
In general, an Internet Standard is a specification that is stable
and well-understood, is technically competent, has multiple,
independent, and interoperable implementations with substantial
operational experience, enjoys significant public support, and is
recognizably useful in some or all parts of the Internet.
Each distinct version of an Internet standards-related
specification is published as part of the "Request for Comments"
(RFC) document series. This archival series is the official
publication channel for Internet standards documents and other
publications of the IESG, IAB, and Internet community. RFCs can
be obtained from a number of Internet hosts using anonymous FTP,
gopher, World Wide Web, and other Internet document-retrieval
systems.
IETF Standards Track [Page 2]
RFC 2500 Internet Standards June 1999
The rules for formatting and submitting an RFC are defined in [5].
Every RFC is available in ASCII text. Some RFCs are also
available in other formats. The other versions of an RFC may
contain material (such as diagrams and figures) that is not
present in the ASCII version, and it may be formatted differently.
*********************************************************
* *
* A stricter requirement applies to standards-track *
* specifications: the ASCII text version is the *
* definitive reference, and therefore it must be a *
* complete and accurate specification of the standard, *
* including all necessary diagrams and illustrations. *
* *
*********************************************************
The status of Internet protocol and service specifications is
summarized periodically in an RFC entitled "Internet Official
Protocol Standards" [1]. This RFC shows the level of maturity and
other helpful information for each Internet protocol or service
specification (see section 3).
Specifications subject to the Internet Standards Process fall into
one of two categories: Technical Specification (TS) and
Applicability Statement (AS).
Some RFCs document Internet Standards. These RFCs form the "STD"
subseries of the RFC series [4]. When a specification has been
adopted as an Internet Standard, it is given the additional label
"STDxxx", but it keeps its RFC number and its place in the RFC
series. (see section 4.1.3)
Some RFCs standardize the results of community deliberations about
statements of principle or conclusions about what is the best way
to perform some operations or IETF process function. These RFCs
form the specification has been adopted as a BCP, it is given the
additional label "BCPxxx", but it keeps its RFC number and its
place in the RFC series. (see section 5)
Not all specifications of protocols or services for the Internet
should or will become Internet Standards or BCPs. Such non-
standards track specifications are not subject to the rules for
Internet standardization. Non-standards track specifications may
be published directly as "Experimental" or "Informational" RFCs at
the discretion of the RFC Editor in consultation with the IESG
(see section 4.2)."
IETF Standards Track [Page 3]
RFC 2500 Internet Standards June 1999
Section 2 of this memo lists all Technical Specification RFCs that
are in the standards track, and Section 3 lists Applicability
Statement RFCs in the standards track. Section 4 lists those
protocol specification RFCs that are off the standards track
(Informational and Historic status). This memo does not list
Informational RFCs that may be of general interest to the community
but do not specify protocols for the Internet. It also does not list
BCP RFCs. Telnet options have been added into the lists.
2. Current Technical Specifications
Subsections 2.1-2.5 list the standards in groups by protocol state.
In the following lists, shorthand nicknames have been shown for many
of the major protocols. These names are commonly used in discourse
on Internet mailing lists.
