集線器和交換機(jī)
中繼型集線器(集線器)
集線器是構(gòu)成以太網(wǎng)拓?fù)涞幕驹O(shè)備,為多端口設(shè)備,有四、八、十二口等,可級(jí)聯(lián)構(gòu)成分散星型拓?fù)洹?/p>
集線器均符合IEEE802.3中繼單元要求。這些要求包括前導(dǎo)碼生成、對(duì)稱和幅度補(bǔ)償。中繼器必須對(duì)信號(hào)再定時(shí),這樣收發(fā)器和電纜引起的信號(hào)抖動(dòng)不會(huì)在多網(wǎng)段傳播時(shí)累積。這些設(shè)備能偵測(cè)出不完整的數(shù)據(jù)包和沖突,并產(chǎn)生一個(gè)阻塞信號(hào)相作用。它們還會(huì)自動(dòng)隔離有問題的端口以維持網(wǎng)絡(luò)正常工作。
