30、絡(luò)操作系統(tǒng)、傳輸介質(zhì)（可以是有形的，也可以是無形的，如無線網(wǎng)絡(luò)的傳輸介質(zhì)就是看不見的電磁波）以及相應(yīng)的應(yīng)用軟件四部分。局域網(wǎng)是一種小范圍內(nèi)的網(wǎng)絡(luò)，是網(wǎng)絡(luò)的組成細胞。一個網(wǎng)絡(luò)有時就是由大大小小的局域網(wǎng)互連而成的，人們在工作與生活中，經(jīng)常使用的是局域網(wǎng)。例如，在一個辦公樓里組建一個可以資源共享的小型辦公局域網(wǎng)。本次設(shè)計即完成一個辦公樓局域網(wǎng)系統(tǒng)的設(shè)計。關(guān)鍵詞：局域網(wǎng)；IP地址；DHCP山東建筑大學(xué)信電學(xué)院課程設(shè)計說明書正 文1 設(shè)計目的本次設(shè)計要求完成一個辦公樓局域網(wǎng)系統(tǒng)的設(shè)計，以實現(xiàn)相應(yīng)功能。目的是將理論與實踐有機結(jié)合起來，通過課程設(shè)計，進一步鞏固和加強對理論的理解和認識，同時提高實際操作能力。

31、2 設(shè)計要求1本樓宇局域網(wǎng)由五層樓組成，共計有120臺電腦需要接入網(wǎng)絡(luò)，但是該小區(qū)物業(yè)只分配100個IP。2. 網(wǎng)絡(luò)傳輸媒體的選擇，交換機類型選擇，網(wǎng)絡(luò)操作系統(tǒng)的選擇，DNS以及WWW服務(wù)器的設(shè)置；中心機房位置選擇，相關(guān)綜合布線要求，網(wǎng)絡(luò)安全措施。3 設(shè)計內(nèi)容3.1系統(tǒng)需求分析 （1）IP地址的分配，采用DHCP技術(shù)。（2）網(wǎng)絡(luò)傳輸媒體的選擇，交換機類型選擇。1）網(wǎng)絡(luò)傳輸媒體選擇：這里選擇有線傳輸介質(zhì)雙絞線中的直通線與交叉線。2）交換機類型選擇：這里選擇CISCO WS-C2960-24智能交換機。參數(shù)如下：應(yīng)用層級：二層 傳輸速率：10/100Mbps 端口數(shù)量：26個 VLAN：支持 網(wǎng)絡(luò)

32、管理：Web瀏覽器，SNMP，C包轉(zhuǎn)發(fā)率：6.5Mpps MAC地址表：8K 網(wǎng)絡(luò)標準：IEEE 802.3，IEEE 8端口結(jié)構(gòu)：非模塊化 交換方式：存儲-轉(zhuǎn)發(fā) 產(chǎn)品內(nèi)存：64MB（3）局域網(wǎng)拓撲結(jié)構(gòu)設(shè)計：采用級連交換機的星型拓撲結(jié)構(gòu)高速局域網(wǎng)。（4）網(wǎng)絡(luò)操作系統(tǒng)的選擇：采用Windows NT操作系統(tǒng)。（5）DNS以及HTTP服務(wù)器的設(shè)置：在服務(wù)器中進行相關(guān)設(shè)置。 （6）中心機房位置選擇，網(wǎng)絡(luò)布線，網(wǎng)絡(luò)連通性測試： 中心機房位置選擇應(yīng)該選擇樓宇中心位置；使用Cisco Packet Tracer軟件進行網(wǎng)絡(luò)布線，模擬網(wǎng)絡(luò)運行的任何細節(jié)，自動捕獲各種類型的數(shù)據(jù)包，分析IP數(shù)據(jù)包的結(jié)構(gòu)，更加直觀的學(xué)習網(wǎng)絡(luò)協(xié)議、分析網(wǎng)絡(luò)性能；采用防火墻技術(shù)。3.2方案設(shè)計3.2.1總體設(shè)計采用2層交換機的級聯(lián)局域網(wǎng)拓撲結(jié)構(gòu)。用1臺CISCO 2960-24TT（24孔）交換機與路由器相連，并連接一個服務(wù)器。因為共有120臺電腦，需用6臺二級交換機與一級交換機級聯(lián)。其中四個樓層分配一臺，一個樓層分配兩臺。整個網(wǎng)絡(luò)通過路由器與外網(wǎng)相連。如下圖所示：3.2.2各部分配置（1）配置路由器（2）服務(wù)器本機配置（3）配置DHCP（4）配置HTTP（5）配置DNS3.2.3測試網(wǎng)絡(luò)（1） 測試DHCP(2)測試DNS和WWW(3)使用計算機不同網(wǎng)段互ping檢查網(wǎng)絡(luò)連通3.2.4網(wǎng)
