      德國(guó)赫斯曼交換機(jī)型號(hào)大全

      德國(guó)赫斯曼交換機(jī)型號(hào)大全
      &ldquo;交換機(jī)&rdquo;是一個(gè)舶來(lái)詞,源自英文&ldquo;switch,原意是&ldquo;開(kāi)關(guān)&rdquo;,我國(guó)技術(shù)界在引入這個(gè)詞匯時(shí),翻譯為&ldquo;交換&rdquo;。在英文中,動(dòng)詞&ldquo;交換&rdquo;和名詞&ldquo;交換機(jī)&rdquo;是同一個(gè)詞(注意這里的&ldquo;交換&rdquo;特指電信技術(shù)中的信號(hào)交換,與物品交換不是同一個(gè)概念)。 1993年,局域網(wǎng)交換設(shè)備出現(xiàn),1994年,國(guó)內(nèi)掀起了交換網(wǎng)絡(luò)技術(shù)的熱潮。其實(shí),交換技術(shù)是一個(gè)具有簡(jiǎn)化、低價(jià)、高性能和口密集特點(diǎn)的交換產(chǎn)品,體現(xiàn)了橋接技術(shù)的復(fù)雜交換技術(shù)在osi參考模型的第二層操作。與橋接器一樣,交換機(jī)按每一個(gè)包中的mac地址相對(duì)簡(jiǎn)單地決策信息轉(zhuǎn)發(fā)。而這種轉(zhuǎn)發(fā)決策一般不考慮包中隱藏的更深的其他信息。與橋接器不同的是交換機(jī)轉(zhuǎn)發(fā)延遲很小,操作接近單個(gè)局域網(wǎng)性能,遠(yuǎn)遠(yuǎn)超過(guò)了普通橋接互
