本月促售Hirschmann交換機(jī)工作在數(shù)據(jù)鏈路層。交換機(jī)擁有一條很高帶寬的背部總線和內(nèi)部交換矩陣。交換機(jī)的所有的端口都掛接在這條背部總線上，控制電路收到數(shù)據(jù)包以后，處理端口會(huì)查找內(nèi)存中的地址對(duì)照表以確定目的MAC（網(wǎng)卡的硬件地址）的NIC（網(wǎng)卡）掛接在哪個(gè)端口上，通過內(nèi)部交換矩陣迅速將數(shù)據(jù)包傳送到目的端口，目的MAC若不存在廣播到所有的端口，接收端口回應(yīng)后交換機(jī)會(huì)“學(xué)習(xí)”新的地址，并把它添加入內(nèi)部MAC地址表中。使用交換機(jī)也可以把網(wǎng)絡(luò)“分段”，通過對(duì)照MAC地址表交換機(jī)只允許必要的網(wǎng)絡(luò)流量通過交換機(jī)。通過交換機(jī)的過濾和轉(zhuǎn)發(fā)，可以有效的減少?zèng)_突域，但它不能劃分網(wǎng)絡(luò)層廣播，即廣播域。交換機(jī)在同一時(shí)刻可進(jìn)行多個(gè)端口對(duì)之間的數(shù)據(jù)傳輸。每一端口都可視為獨(dú)立的網(wǎng)段想更清楚的了解Hirschmann交換機(jī)就直接與我司，業(yè)務(wù):零二一，六二一二一二八六，傳真;零二一，五二三七一六九七，劉小燕 Hirschmann交換機(jī)的全雙工是指交換機(jī)在發(fā)送數(shù)據(jù)的同時(shí)也能夠接收數(shù)據(jù)，兩者同步進(jìn)行，這好像我們平時(shí)打一樣，說話的同時(shí)也能夠聽到對(duì)方的聲音。目前的交換機(jī)都支持全雙工。全雙工的好處在于遲延小，速度快。 　　提到全雙工，就不能不提與之密切對(duì)應(yīng)的另一個(gè)概念，那就是“半雙工”，所謂半雙工就是指一個(gè)時(shí)間段內(nèi)只有一個(gè)動(dòng)作發(fā)生，舉個(gè)簡(jiǎn)單例子，一條窄窄的馬路
