HIRSCHMANN赫斯曼交換機(jī)

HIRSCHMANN赫斯曼交換機(jī)赫斯曼電子公司位于德國(guó)的Neckartenzlingen，產(chǎn)品范圍包括采用模擬和數(shù)字廣播電視傳輸技術(shù)的移動(dòng)發(fā)射和接收系統(tǒng)，企業(yè)和工業(yè)網(wǎng)絡(luò)解決方案以及現(xiàn)場(chǎng)總線系統(tǒng)。公司由“香蕉插頭"之父Richard Hirschmann于1924年創(chuàng)立。歷經(jīng)81年，赫斯曼這個(gè)當(dāng)初只有一個(gè)人的公司已經(jīng)發(fā)展成為在現(xiàn)代通信領(lǐng)域的一個(gè)現(xiàn)代化企業(yè)。 　　

自1997年1月1日起，赫斯曼公司加入Rheinmetall集團(tuán)的電子部，作為Aditron AG的一個(gè)成員，開(kāi)發(fā)并生產(chǎn)汽車電子、多媒體通信系統(tǒng)和自動(dòng)化網(wǎng)絡(luò)系統(tǒng)的產(chǎn)品。2004年3月24日，赫斯曼公司又加入了的金融投資公司HgCapital集團(tuán)。 　　

赫斯曼的技術(shù)實(shí)力主要體現(xiàn)在汽車通訊系統(tǒng)、多媒體電子、自動(dòng)化網(wǎng)絡(luò)解決方案和電子控制系統(tǒng)。為了使公司結(jié)構(gòu)更加清晰，在2003年1月初成立了多媒體部門，即赫斯曼多媒體電子公司。現(xiàn)在，赫斯曼收購(gòu)了從前的姊妹公司，坐落于Ettlingen的PAT公司，她的電子控制系統(tǒng)部門已經(jīng)在赫斯曼集團(tuán)旗下。 　　

作為的集成天線系統(tǒng)制造商，赫斯曼開(kāi)發(fā)了許多創(chuàng)新的產(chǎn)品，例如*個(gè)集成在汽車后保險(xiǎn)杠中的接收天線，同時(shí)也是汽車后窗玻璃使用的模塊化天線系統(tǒng)的者。赫斯曼成功地推出了一系列的移動(dòng)發(fā)射和接收系統(tǒng)，適用于廣播接收、通信、導(dǎo)航、車（船）隊(duì)管理和通信等領(lǐng)域。 　　

赫斯曼在多媒體通信領(lǐng)域也處在的位置，這包括傳輸模擬和數(shù)字廣播信號(hào)的系統(tǒng)和組件，用于專業(yè)的CATV網(wǎng)絡(luò)和家用的衛(wèi)星地面站系統(tǒng)。 　　

作為自動(dòng)化網(wǎng)絡(luò)方面的專家，1984年赫斯曼在德國(guó)的斯圖加特大學(xué)建立了世界上*條光纖以太網(wǎng)，1990年，又在**個(gè)推出了環(huán)形冗余以太網(wǎng)（HIPER-Ring）。赫斯曼提供了完整而又全面的適用于工業(yè)環(huán)境和辦公環(huán)境的數(shù)據(jù)通信體系，產(chǎn)品范圍從千兆以太網(wǎng)、快速以太網(wǎng)和以太網(wǎng)產(chǎn)品，到現(xiàn)場(chǎng)總線系統(tǒng)，以及執(zhí)行器和傳感器所使用的ASI連接器，這些產(chǎn)品信息廣泛，主要應(yīng)用范圍包括辦公室通信、生產(chǎn)自動(dòng)化、過(guò)程控制、交通控制，以及獨(dú)立的機(jī)器設(shè)備控制系統(tǒng)。 　　在汽車工廠電子的市場(chǎng)上，電子控制系統(tǒng)部門（由PAT公司并入）的載荷顯示儀和載荷矩限制器產(chǎn)品深受好評(píng)。在這一領(lǐng)域，赫斯曼開(kāi)發(fā)并生產(chǎn)基于微處理器控制的安全的軟硬件系統(tǒng)。赫斯曼集團(tuán)的電子控制系統(tǒng)將繼續(xù)以她的品牌PAT和KRUGER行銷市場(chǎng)，并將在傳統(tǒng)建筑機(jī)械行業(yè)以外，如原料處理，得到更廣泛的應(yīng)用。 　　

HIRSCHMANN赫斯曼交換機(jī)

赫斯曼電子集團(tuán)在德國(guó)和匈牙利都有自己的生產(chǎn)廠房，分部更是遍及眾多歐洲國(guó)家、美國(guó)及亞洲。

　　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(guò)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(guò)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(guò)交換機(jī)。通過(guò)交換機(jī)的過(guò)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，連接在其上的網(wǎng)絡(luò)設(shè)備獨(dú)自享有全部的帶寬，無(wú)須同其他設(shè)備競(jìng)爭(zhēng)使用。當(dāng)節(jié)點(diǎn)A向節(jié)點(diǎn)D發(fā)送數(shù)據(jù)時(shí)，節(jié)點(diǎn)B可同時(shí)向節(jié)點(diǎn)C發(fā)送數(shù)據(jù)，而且這兩個(gè)傳輸都享有網(wǎng)絡(luò)的全部帶寬，都有著自己的虛擬連接。假使這里使用的是10Mbps的以太網(wǎng)交換機(jī)，那么該交換機(jī)這時(shí)的總流通量就等于2×10Mbps=20Mbps，而使用10Mbps的共享式HUB時(shí)，一個(gè)HUB的總流通量也不會(huì)超出10Mbps?？傊?，交換機(jī)是一種基于MAC地址識(shí)別，能完成封裝轉(zhuǎn)發(fā)數(shù)據(jù)包功能的網(wǎng)絡(luò)設(shè)備。交換機(jī)可以“學(xué)習(xí)"MAC地址，并把其存放在內(nèi)部地址表中，通過(guò)在數(shù)據(jù)幀的始發(fā)者和目標(biāo)接收者之間建立臨時(shí)的交換路徑，使數(shù)據(jù)幀直接由源地址到達(dá)目的地址。
