網(wǎng)橋 網(wǎng)橋概述： 依據(jù)幀地址進(jìn)行轉(zhuǎn)發(fā)的二層網(wǎng)絡(luò)設(shè)備，可將數(shù)個(gè)局域網(wǎng)網(wǎng)段連接在一起 。網(wǎng)橋可連接相同介質(zhì)的網(wǎng)段也可訪問(wèn)不同介質(zhì)的網(wǎng)段。網(wǎng)橋的主要作 用是分割和減少?zèng)_突。它的工作原理同交換機(jī)類(lèi)似，也是通過(guò)MAC地址 表進(jìn)行轉(zhuǎn)發(fā)。網(wǎng)橋主要完成三個(gè)功能：轉(zhuǎn)發(fā)、過(guò)濾數(shù)據(jù)幀；幀格式轉(zhuǎn)換 ；傳輸速率轉(zhuǎn)換。 透明網(wǎng)橋：無(wú)需改動(dòng)設(shè)備的軟硬件配置，即可完成LAN互連的網(wǎng)橋。交換 機(jī)可看做多端口透明網(wǎng)橋。 路由器的簡(jiǎn)單介紹
