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)的總流通量聯(lián)系人 廈門彬碩-小胡
電話18900224342 0592-5588308 QQ：469126278德國(guó)西門子交換機(jī)意為“開關(guān)”是一種用于電（光）信號(hào)轉(zhuǎn)發(fā)的網(wǎng)絡(luò)設(shè)備。它可以為接入交換機(jī)的任意兩個(gè)網(wǎng)絡(luò)節(jié)點(diǎn)提供獨(dú)享的電信號(hào)通路。最常見的交換機(jī)是以太網(wǎng)交換機(jī)。其他常見的還有電話語(yǔ)音交換機(jī)、光纖交換機(jī)等。SIEMENS: 3RK 3RA 3RB 3RF 3RG 3RH 3RN 3RP 3RS 3RT 3RV 3RX 3SK 3TC 3TD 3TG 3TH 3TK 3TS 3TX 3UF 3UG 3LD 8WD 6GK 6SE70 6SY 6DD 6RY 6SB 6SL39特價(jià)供應(yīng)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。總之，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)幀功能的網(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6GK5798-0AP00-4CA0
