網(wǎng)絡(luò)優(yōu)勢(shì)分析
以太網(wǎng)的方案是基于二層交換傳輸方案。采用以太網(wǎng)作為交換傳輸和接入平臺(tái)的優(yōu)勢(shì)十分明顯。其一是巨大的網(wǎng)絡(luò)基礎(chǔ)和*的經(jīng)驗(yàn)知識(shí),以及目前所有流行的操作系統(tǒng)和應(yīng)用也都與以太網(wǎng)兼容;其二,以太網(wǎng)性能價(jià)格比好,初始成本和運(yùn)營成本均較低;另外,以太網(wǎng)的擴(kuò)展性好,容易安裝開通,并且可靠性較高。以太網(wǎng)接入采用異步工作方式,很適合于處理IP突發(fā)數(shù)據(jù)流。目前以太網(wǎng)從共享媒質(zhì)轉(zhuǎn)向全雙工LAN交換后,在相當(dāng)程度上實(shí)現(xiàn)了計(jì)算機(jī)間的信息隔離,消除了鏈路帶寬的競(jìng)爭(zhēng)和潛在的碰撞機(jī)會(huì),同時(shí)使以太網(wǎng)的傳輸距離也大大地得到擴(kuò)展。
