“交換機”是一個舶來詞,源自英文“Switch,原意是“開關(guān)”,我國技術(shù)界在引入這個詞匯時,翻譯為“交換”。在英文中,動詞“交換”和名詞“交換機”是同一個詞(注意這里的“交換”特指電信技術(shù)中的信號交換,與物品交換不是同一個概念)。 1993年,局域網(wǎng)交換設(shè)備出現(xiàn),1994年,國內(nèi)掀起了交換網(wǎng)絡(luò)技術(shù)的熱潮。其實,交換技術(shù)是一個具有簡化、低價、高性能和口密集特點的交換產(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,交換機按每一個包中的MAC地址相對簡單地決策信息轉(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轉(zhuǎn)發(fā)延遲很小,操作接近單個局域網(wǎng)性能,遠遠超過了普通橋接互
