14、4 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 802.3a
15、p-20xx). A historical listing of projects that have added to or modified IEEE Std 802.3 is included in IEEE Std 802.3-2005. 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 e
16、xperimental 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 t
17、he 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 dup
18、lex 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
19、 additions are all now included in IEEE Std 802.3-2005 and are not maintained as separate documents. This amend- ment adds additional capabilities for Ethernet Operation over Electrical Backplanes. At the date of IEEE Std 802.3ap-20xx publication, IEEE Std 802.3 is comprised of the following documen
20、ts: Section OneIncludes 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 TwoIncludes Clause 21 through Clause 33 and Annex 22A
21、 through Annex 33E. Section Two includes management attributes for multiple protocols and speeds 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 1
22、00 Mb/s physical layer specifcations. Section ThreeIncludes Clause 34 through Clause 43 and Annex 36A through Annex 43C. Section Three includes general information on 1000 Mb/s operation as well as most of the 1000 Mb/s physical layer speci- fications. It also includes specification of 802.3 link ag
23、gregation. Section FourIncludes Clause 44 through Clause 54 and Annex 44A through Annex 50A. Section Four includes general information on 10 Gb/s operation as well as most of the 10 Gb/s physical layer specifica- tions. Section FiveIncludes Clause 56 through Clause 67 and Annex 58A through Annex 67A
24、. Section Five includes subscriber access physical layers and sublayers for operation from 512 kb/s to 1000 Mb/s, and defines services and protocol elements that enable the exchange of IEEE Std 802.3 format frames between stations in a subscriber access network.

30、ncludes changes to IEEE Std 802.3-2005 and adds Clause 69 through Clause 74 and Annex 69A, Annex 69B, Annex 73A and Annex 74A. This amendment adds new Physical Layers that support the exchange of IEEE Std 802.3 format frames over electrical backplanes at 1 Gb/s and 10 Gb/s. IEEE Std 802.3 will conti
31、nue to evolve. New Ethernet capabilities are anticipated to be added within the next few years as amendments to this standard. Conformance test methodology An additional standard, IEEE Std 1802.3-2001, provides conformance test information for 10BASE-T. Editors Note (to be removed prior to publicati
