BOF - Birds of a Feather
A BOF is a session at an IETF meeting which permits "market research" and technical "brainstorming." Often
BOFs are held to explore whether an issue merits the formation of a working group. In addition, a BOF may serve
as a forum for a single presentation or discussion, without any intent to form a working group.
A Contribution is any submission to the IETF intended by the
Contributor for publication as all or part of an Internet-Draft or
RFC (except for RFC Editor Contributions described in RFC 5378, Section 4) and any statement made within the context
of an IETF activity. Such statements include oral statements in IETF
sessions as well as written and electronic communications, made at
any time or place, that are addressed to:
- the IETF plenary session,
- any IETF working group or portion thereof,
- any Birds of a Feather (BOF) session,
- the IESG, or any member thereof on behalf of the IESG,
- the IAB, or any member thereof on behalf of the IAB,
- any IETF mailing list, including the IETF list itself, any
working group or design team list, or any other list functioning
under IETF auspices,
- the RFC Editor or the Internet-Drafts function (except for RFC
Editor Contributions, as described in RFC 5378, Section 4).
Statements made outside of an IETF session, mailing list, or other
function, that are clearly not intended to be input to an IETF
activity, group, or function are not IETF Contributions in the
context of this document.
A Contributor is an individual submitting a Contribution.
Copyright is the legal right granted to an author in a document or
other work of authorship under applicable law. A "copyright" is
not equivalent to a "right to copy". Rather a copyright
encompasses all of the exclusive rights that an author has in a
work, such as the rights to copy, publish, distribute and create
derivative works of the work. An author often cedes these rights
to his or her employer or other parties as a condition of
employment or compensation.
A person responsible for tracking and facilitating document progression
through RFC publication.
The basic concept of document shepherding is for a a single person
to take responsibility for a document from the time
the WG Chair(s) requests the IESG to publish it to the time that it
is given final edits by the RFC Editor. The motivation is for the
shepherd to provide needed coordination. It is easy to lose important
information or cause delays without the shepherd's coordination.

- Internet Architecture Board
The IAB is responsible for defining the overall architecture of the Internet, providing guidance and broad
direction to the IETF. The IAB also serves as the technology advisory group to the Internet Society, and oversees
a number of critical activities in support of the Internet.
IAD - IETF Administrative Director
IANA - Internet Assigned Numbers Authority
Based at ICANN, IANA is in charge of all "unique parameters" on the Internet, including IP (Internet
Protocol) addresses. Each domain name is associated with a unique IP address, a numerical name consisting of
four blocks of up to three digits each, e.g. 126.96.36.199, which systems use to direct information through
IAOC - IETF Administrative Oversight Committee
IASA - IETF Administrative Support Activity
ICANN - Internet Corporation for Assigned Names and Numbers
I-D - Internet-Draft
I-Ds are working documents of the IETF, its areas, and its working groups. During the development of a specification,
draft versions of the document are made available for informal review and comment by placing them in the
IETF's Internet-Drafts directory. This makes an evolving working document readily available to a wide audience,
facilitating the process of review and revision.
IESG - Internet Engineering Steering Group
The IESG is responsible for technical management of IETF activities and the Internet standards process. As
part of the ISOC, it administers the process according to the rules and procedures which have been ratified
by the ISOC Trustees. The IESG is directly responsible for the actions associated with entry into and movement
along the Internet "standards track," including final approval of specifications as Internet Standards.
IETF - Internet Engineering Task Force
The IETF is the protocol engineering and development arm of the Internet. Though it existed informally for
some time, the group was formally established by the IAB in 1986 with Phill Gross as the
An Indirect Contributor is any person who has materially or
substantially contributed to a Contribution without being
personally involved in its submission to the IETF.

ISOC - Internet Society
The Internet Society is a professional membership organization of Internet experts that comments on policies
and practices and oversees a number of other boards and task forces dealing with network policy issues.

A Last Call is a notice sent to the IETF community (via the IETF-Announce email list) on such topics as pending
IESG consideration of documents, sent in order to permit a final review by the general Internet community.
MISSREF - Missing Reference
Documents in the RFC Editor Queue that have normative
references to other documents that have not yet been approved for
A normative reference specifies a document that must be read to fully understand or implement the subject matter in the new RFC, or whose contents are effectively part of the new RFC, as its omission would leave the new RFC incompletely specified.

WG - Working Group
WGs are the primary mechanism for development of IETF specifications and guidelines, many of which are intended
