1、畢業(yè)設(shè)計(jì)(論文)中小型局域網(wǎng)的設(shè)計(jì)與規(guī)劃摘要:隨著網(wǎng)絡(luò)技術(shù)新系統(tǒng),新領(lǐng)域的長足發(fā)展,傳統(tǒng)企業(yè)也正利用其行業(yè)的特點(diǎn),融合網(wǎng)絡(luò)技術(shù)的優(yōu)勢,發(fā)展其身。在信息化生產(chǎn)逐步普及的今天,組建企業(yè)內(nèi)部網(wǎng)絡(luò)已經(jīng)是企業(yè)必不可少的一部分,建立高速,穩(wěn)定,安全,智能的辦公網(wǎng)絡(luò),是組建中小型企業(yè)局域網(wǎng)的核心。本論文所闡述的是企業(yè)網(wǎng)絡(luò)的規(guī)劃與設(shè)計(jì)是使用業(yè)界流行的核心層——匯聚層——分布層三層結(jié)構(gòu)設(shè)計(jì)的中小型企業(yè)網(wǎng),結(jié)合廣為使用的虛擬局域網(wǎng)(VLAN),熱備份路由(HSRP),訪問控制列表(ACL),網(wǎng)絡(luò)地址轉(zhuǎn)換(NAT)等技術(shù),增強(qiáng)網(wǎng)絡(luò)的穩(wěn)定性和安全性。設(shè)計(jì)中采用虛擬
2、局域網(wǎng)來隔離不同部門,以達(dá)到增強(qiáng)企業(yè)網(wǎng)絡(luò)安全性目的;在規(guī)劃好的VALN的基礎(chǔ)上,采用訪問控制列表(ACL),設(shè)置策略來限制部門之間以及服務(wù)器區(qū)的訪問,進(jìn)一步提高企業(yè)網(wǎng)絡(luò)內(nèi)部的安全性;并在核心層交換機(jī)上采用熱備份路由(RSRP)技術(shù),增加網(wǎng)絡(luò)的冗余容錯(cuò)功能,提高企業(yè)網(wǎng)絡(luò)的整體穩(wěn)定性;;采用路由器硬件的動(dòng)態(tài)主機(jī)分配協(xié)議(DHCP)功能,保證各部門IP地址的獲??;在邊界路由器上設(shè)置網(wǎng)絡(luò)地址轉(zhuǎn)換(NAT),將企業(yè)內(nèi)部私有地址轉(zhuǎn)為公網(wǎng)地址,實(shí)現(xiàn)了多個(gè)用戶同時(shí)共用一個(gè)合法IP與外部Internet進(jìn)行通信,解決IP地址短缺的問題。關(guān)鍵詞:中小型;穩(wěn)定性
