一、概述目前Ethernet是局部网络中比较流行的一种。它是美国XEROX公司1975年设计实现的。后来DEC、Intel和XEROX三家公司合作于1980年9月正式公布了Ethernet的物理层和数据链路层的详细规范(V1.0版,后又于1982年11月公布了V2.0版规范)。IEEE802局部网络标准委员会公布的IEEER02.3标准与Ethernet规范几乎完全相同。Ethernet规范是以XEROX初期的实验性Ethernet为基础,吸
I. Overview At present, Ethernet is one of the more popular local networks. It is the United States designed XEROX company in 1975. Later DEC, Intel and XEROX three companies formally announced in September 1980 the Ethernet physical layer and data link layer detailed specification (V1.0 version, later released in November 1982 version V2.0 specification) . IEEE802 local network standards committee announced IEEER02.3 standards and Ethernet specifications are almost identical. The Ethernet specification is based on the experimental Ethernet XEROX initial absorption
