局域網(wǎng)與城域網(wǎng)

內(nèi)容概要

這本英文原版教材對局域網(wǎng)/城域網(wǎng)技術(shù)進(jìn)行了全面的探討，既強(qiáng)調(diào)了基本原理，也注重在設(shè)計局域網(wǎng)/城域網(wǎng)時性能的重要性。本書還涉及了各種高速和無線局域網(wǎng)、與QoS相關(guān)的技術(shù)以及網(wǎng)絡(luò)之間的互聯(lián)和廣域網(wǎng)。全書包括四個部分。第一部分提供必要的技術(shù)背景，內(nèi)容包括對數(shù)據(jù)通信和網(wǎng)絡(luò)中的一些論題的簡要回顧以及對協(xié)議與TCP/IP協(xié)議棧的介紹。第二部分討論局域網(wǎng)的一般性問題，內(nèi)容包括局域網(wǎng)實(shí)現(xiàn)過程中常用的拓?fù)浣Y(jié)構(gòu)和傳輸介質(zhì)、局域網(wǎng)協(xié)議體系結(jié)構(gòu)以及LLC的詳細(xì)內(nèi)容。第三部分是本書的重點(diǎn)，主要介紹五種相關(guān)類型的局域網(wǎng)，內(nèi)容包括以太網(wǎng)、令牌環(huán)網(wǎng)、光纖信道局域網(wǎng)與無線局域網(wǎng)以及異步傳輸模式（ATM）局域網(wǎng)。第四部分討論有關(guān)局域網(wǎng)設(shè)計的一些問題，包括用網(wǎng)橋進(jìn)行局域網(wǎng)互聯(lián)、網(wǎng)際互聯(lián)、網(wǎng)絡(luò)管理及性能考慮等問題。
本書適合高等院校電子、計算機(jī)、通信類專業(yè)作為雙語教學(xué)的教材，也適應(yīng)專業(yè)技術(shù)人員參考。
