Telecommunications and exchange between information technology systems — Requirements for local and metropolitan area networks — Part 3: Standard for Ethernet 信息技术系统间的通信和交换局域网和城域网的要求第3部分:以太网标准

发布日期： 2021-02-23

本文档定义了以太网局域网、接入和城域网。以选定的操作速度指定以太网；并且使用公共媒体访问控制(MAC)规范和管理信息库(MIB)。具有冲突检测的载波侦听多址(CSMA/CD)MAC协议指定共享介质(半双工)操作以及全双工操作。速度特定介质独立接口（MIIs）向选定的物理层实体（PHY）提供架构和可选实现接口。物理层对用于传输的帧进行编码，并利用为操作速度、传输介质和支持的链路长度指定的调制对接收的帧进行解码。其他指定的功能包括:控制和管理协议，以及通过选定的双绞线PHY类型提供电源。

This document defines Ethernet local area, access and metropolitan area networks. Ethernet is specified at selected speeds of operation; and uses a common media access control (MAC) specification and management information base (MIB). The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) provide an architectural and optional implementation interface to selected Physical Layer entities (PHY). The Physical Layer encodes frames for transmission and decodes received frames with the modulation specified for the speed of operation, transmission medium and supported link length. Other specified capabilities include: control and management protocols, and the provision of power over selected twisted pair PHY types.
