1、大型企業(yè)網(wǎng)絡(luò)規(guī)劃與設(shè)計1大型企業(yè)網(wǎng)絡(luò)規(guī)劃與設(shè)計摘要迅速發(fā)展的Inter正在對全世界的信息產(chǎn)業(yè)帶來巨大的變革和深遠(yuǎn)的影響。市場的全球化競爭已成為趨勢。對于大型企業(yè)來說，在調(diào)整發(fā)展戰(zhàn)略時，必須考慮到市場的全球競爭戰(zhàn)略，而這一切也將以信息化平臺為基礎(chǔ)，借助計算機(jī)網(wǎng)絡(luò)原理及網(wǎng)絡(luò)規(guī)劃技術(shù)，以網(wǎng)絡(luò)通暢為保證。企業(yè)內(nèi)部網(wǎng)（Intra）是國際互連網(wǎng)（Inter）技術(shù)在企業(yè)內(nèi)部或封閉的用戶群內(nèi)的應(yīng)用。Intra是使用Inter技術(shù)特別是TCPIP協(xié)議而建

2、成的企業(yè)內(nèi)部網(wǎng)絡(luò)。這種技術(shù)允許不同計算機(jī)平臺進(jìn)行互通且不用考慮其位置。也就是所說的用戶可以對任何一臺進(jìn)行訪問或從任何一臺計算機(jī)進(jìn)行訪問。本文從企業(yè)網(wǎng)絡(luò)需求開始分析，根據(jù)現(xiàn)階段cisco公司主流網(wǎng)絡(luò)設(shè)備進(jìn)行選材規(guī)劃最適用于目標(biāo)網(wǎng)絡(luò)的拓?fù)浣Y(jié)構(gòu)建設(shè)合理的網(wǎng)絡(luò)設(shè)計方案。本課題實(shí)施部分由GNS3模擬器來搭建網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)，利用cisco設(shè)備操作系統(tǒng)unzipc2691advsecurityk9mz.12411.T2作為拓?fù)鋬?nèi)所有設(shè)備核心IOS，然后
