About This Item

 

Full Description

Scope

To define the specification for bi-directional, simultaneous transmission and reception of IEEE 802.3 frames over media capable of supporting simultaneous bi-directional signaling (twisted pair and/or fiber). Flow control mechanisms will be addressed as relevant.

Purpose

This standard will provide a higher performance option to the existing standard that allows performance to be optimized for IEEE 802.3 LANs (currently 10 and 100 Mb/s). This performance enhancement is made possible by the separate transmit and receive channels of twosted pair and/or fiber technologies. This standard will allow significant performance improvement and will provide a basis for interoperation of products referred to as 802.3 Full Duplex.

Abstract

Amendment Standard - Superseded. Superseded by IEEE Std 802.3-2002 Necessary changes and additions are made to provide for an additional, full duplex mode of operation on a speed-independent basis. Changes are made to the MAC and selected Physical Layer implementations (10BASE-T, 10BASE-FL, 100BASE-T) to support full duplex. A mechanism for pause-based flow control is also added.p> Abstract 802.3y: Changes and additions to the 100BASE-T portion of IEEE Std 802.3 are provided to specify an additional 100 Mb/s transceiver type 100BASE-T, which can support full duplex operation over two pairs of Category 3 or better cabling.
