Introduction
IEEE Std 802.3™ was first published in 1985. Since the initial publication, many projects have added func-
tionality or provided maintenance updates to the specifications and text included in the standard. Each IEEE
802.3 project/amendment is identified with a suffix (e.g., IEEE 802.3an-2006). A historical listing of all
projects that have added to or modified IEEE Std 802.3 follows as a part of this introductory material. The
listing is in chronological order of project initiation and for each project describes: subject, clauses added (if
any), approval dates, and committee officers.
The Media Access Control (MAC) protocol specified in IEEE Std 802.3 is Carrier Sense Multiple Access
with Collision Detection (CSMA/CD). This MAC protocol was included in the experimental Ethernet devel-
oped at Xerox Palo Alto Research Center. While the experimental Ethernet had a 2.94 Mb/s data rate, IEEE
Std 802.3-1985 specified operation at 10 Mb/s. Since 1985 new media options, new speeds of operation, and
new capabilities have been added to IEEE Std 802.3.
Some of the major additions to IEEE Std 802.3 are identified in the marketplace with their project number.
This is most common for projects adding higher speeds of operation or new protocols. For example, IEEE
Std 802.3u added 100 Mb/s operation (also called Fast Ethernet), IEEE Std 802.3x specified full duplex
operation and a flow control protocol, IEEE Std 802.3z added 1000 Mb/s operation (also called Gigabit
Ethernet), IEEE Std 802.3ae added 10 Gb/s operation (also called 10 Gigabit Ethernet) and IEEE Std
802.3ah specified access network Ethernet (also called Ethernet in the First Mile). These major additions are
all now included in, and are superceded by, IEEE Std 802.3-200X and are not maintained as separate docu-
ments.
At the date of IEEE Std 802.3xx-200X publication, IEEE Std 802.3 is comprised of the following docu-
ments:
IEEE Std 802.3-200X
Section One -- Includes Clause 1 through Clause 20 and Annex A through Annex H and Annex 4A. Section
One includes the specifications for 10 Mb/s operation and the MAC, frame formats and service interfaces
used for all speeds of operation.
Section Two -- Includes Clause 21 through Clause 33 and Annex 22A through Annex 33E. Section Two
includes management attributes for multiple protocols and speed of operation as well as specifications for
providing power over twisted pair cabling for multiple operational speeds. It also includes general informa-
tion on 100 Mb/s operation as well as most of the 100 Mb/s physical layer specifications..
Editor’s Note (to be removed prior to publication):
This front matter is provided for comment only. Front matter is not part of a published standard and is
therefore, not part of the draft standard. You are invited to review and comment on it as it will be included
in the published standard after approval.
One exceptions to IEEE style that is conciously used to simplify the balloting process is the numbering of
the front matter. Instead of the front matter being lower case Roman numeral page numbers, with the draft
restarting at 1 with arabic page numbers, balloted front matter and draft are numbered consecuively with
arabic page numbers.
This introduction is not part of IEEE Std 802.3xx-200X, IEEE Standard for Information technology—Tele-
communications and information exchange between systems—Local and metropolitan area networks—Spe-
cific requirements, Part 3: CSMA/CD Access Method and Physical Layer Specifications, Amendment:
