2、源共享等各種應(yīng) 用；利用現(xiàn)代信息技術(shù)從事管理、教學(xué)和科學(xué)研究等工作。本次的實(shí)訓(xùn)就是設(shè)計(jì)規(guī)劃一個(gè)小型校園網(wǎng)，通過作需求的分析，并設(shè)計(jì)畫 網(wǎng)絡(luò)拓?fù)鋱D和IP地址的規(guī)劃等工作。最終，利用實(shí)驗(yàn)室設(shè)備和boson software軟件組建一個(gè)模擬的小型校園網(wǎng)，并對(duì)校園網(wǎng)內(nèi)的各種互聯(lián)設(shè)備和部 門進(jìn)行綜合配置，以了解和熟悉校園網(wǎng)建設(shè)的過程。關(guān)鍵詞：信息，校園網(wǎng)，網(wǎng)絡(luò)拓?fù)?，IP地址，boson software網(wǎng)絡(luò)系統(tǒng)工程綜合實(shí)訓(xùn)某小型校園網(wǎng)規(guī)劃與設(shè)計(jì)要點(diǎn)2/25一、一、 實(shí)訓(xùn)題目與設(shè)計(jì)要求實(shí)訓(xùn)題目與設(shè)計(jì)要求1、 實(shí)訓(xùn)題目某小型校園網(wǎng)規(guī)劃與設(shè)計(jì)2、 網(wǎng)絡(luò)設(shè)計(jì)要求本次實(shí)訓(xùn)要求規(guī)劃的校園網(wǎng)內(nèi)覆蓋五個(gè)大樓，分別是教學(xué)

3、樓、實(shí)驗(yàn)樓、圖 書館、辦公樓和學(xué)生宿舍樓，外與Internet相連接。其具體設(shè)計(jì)要求如下1）內(nèi)網(wǎng)計(jì)算機(jī)共享兩個(gè)全局IP地址（和59. 78. 84. 2 ）上Internet o （提示：做NAT動(dòng)態(tài)地址映射）。2）不同大樓內(nèi)的客戶機(jī)劃分不同的VLAN,以控制廣播風(fēng)暴。3）辦公樓和教學(xué)樓的計(jì)算機(jī)能互相通信。4）校園內(nèi)所有計(jì)算機(jī)都能訪問服務(wù)器。5）給校園內(nèi)各個(gè)部門的機(jī)器分配內(nèi)網(wǎng)地址。6）給校園內(nèi)的服務(wù)器（等）分配內(nèi)網(wǎng)地址，并要求外網(wǎng)用戶可以訪問。（提 示：做NAT靜態(tài)地址映射,外部地址是59. 78. 1. 1和59. 78. 84. 9）。7）教學(xué)樓100臺(tái)機(jī)器，實(shí)驗(yàn)樓15

5、在服務(wù)器訪問外部網(wǎng)絡(luò)時(shí)，可以一對(duì)一的轉(zhuǎn)換分配外部的地址。而通過動(dòng)態(tài)地 址的轉(zhuǎn)換則可以實(shí)現(xiàn)校園網(wǎng)內(nèi)的所有主機(jī)共享兩個(gè)全局IF地址（內(nèi)部合法地 址）訪問Internet。但山于每棟大樓的主機(jī)數(shù)都是上百的，在設(shè)計(jì)時(shí)如果把所 有主機(jī)都連上會(huì)比較的麻煩和不實(shí)際，所以在設(shè)計(jì)拓?fù)鋱D時(shí)我就在母棟樓選了 兩臺(tái)主機(jī)作為代表。以下就是我設(shè)計(jì)規(guī)劃的網(wǎng)絡(luò)拓?fù)淇驁D：網(wǎng)絡(luò)系統(tǒng)工程綜合實(shí)訓(xùn)某小型校園網(wǎng)規(guī)劃與設(shè)計(jì)要點(diǎn)3/25網(wǎng)絡(luò)系統(tǒng)工程綜合實(shí)訓(xùn)某小型校園網(wǎng)規(guī)劃與設(shè)計(jì)要點(diǎn)4/25三、網(wǎng)絡(luò)設(shè)備選型三、網(wǎng)絡(luò)設(shè)備選型在boson software軟件上畫仿真拓?fù)鋱D時(shí)，5臺(tái)交換機(jī)的型號(hào)我都選用了 3550,路由器Rl, R2, R3用了
