【摘要】：伴隨著我國(guó)現(xiàn)代化教育事業(yè)的不斷發(fā)展，數(shù)字化校園的建設(shè)被提上了議事日程。在學(xué)校的建設(shè)中，無論從教學(xué)、學(xué)習(xí)還是日常生活，都已經(jīng)越來越離不開校園網(wǎng)絡(luò)。而在這其中，當(dāng)前對(duì)于無線網(wǎng)絡(luò)的需要更顯的尤為迫切。 在傳統(tǒng)的校園網(wǎng)絡(luò)的架設(shè)過程中，一般都是以有線網(wǎng)絡(luò)的架設(shè)為主，因?yàn)橛芯�網(wǎng)絡(luò)所具備的穩(wěn)定性優(yōu)點(diǎn)，使得在校園的網(wǎng)絡(luò)設(shè)計(jì)中，通常都是采用有線網(wǎng)絡(luò)來實(shí)現(xiàn)信息的傳輸。但是隨著人們生活水平的不斷提高，智能手機(jī)、筆記本電腦和平板電腦等移動(dòng)終端設(shè)備在人們的日常生活中大量普及，有線網(wǎng)絡(luò)已經(jīng)無法滿足學(xué)校教職工和學(xué)生的日常的學(xué)習(xí)和工作。當(dāng)前4G網(wǎng)絡(luò)興起和普及，表明網(wǎng)絡(luò)的帶寬已經(jīng)不再是無線網(wǎng)絡(luò)的限制。良好的網(wǎng)絡(luò)帶給了我們利用無線網(wǎng)絡(luò)的時(shí)機(jī)，學(xué)校也急需通過無線網(wǎng)絡(luò)的建設(shè)，使校園網(wǎng)絡(luò)能夠獲得充分的利用。 論文主要結(jié)合學(xué)�，F(xiàn)有的網(wǎng)絡(luò)技術(shù)和校園網(wǎng)絡(luò)環(huán)境，分析出校園網(wǎng)絡(luò)的不足之處，，提出一個(gè)基于校園網(wǎng)絡(luò)的無線方案，解決了對(duì)于有線網(wǎng)絡(luò)布線的盲點(diǎn)；無線信道檢測(cè)劃分；無線網(wǎng)絡(luò)的安全認(rèn)證和管理；用戶對(duì)無線網(wǎng)絡(luò)需求等一系列的問題。在校園有線網(wǎng)絡(luò)的架構(gòu)下，設(shè)計(jì)了無線網(wǎng)絡(luò)結(jié)構(gòu)拓?fù)�；�?duì)用戶VLAN（Virtual Local Area Network）和管理VLAN進(jìn)行劃分，對(duì)核心交換機(jī)進(jìn)行配置；根據(jù)現(xiàn)場(chǎng)勘察，設(shè)計(jì)了無線接入點(diǎn)的分配方法以及實(shí)施步驟；根據(jù)無線網(wǎng)絡(luò)的安全性需求提出了一個(gè)符合校園網(wǎng)的認(rèn)證解決方案以及具體實(shí)現(xiàn)。在研究過程中，存在幾個(gè)技術(shù)難點(diǎn)：不同認(rèn)證系統(tǒng)，不同的廠家，有線網(wǎng)絡(luò)認(rèn)證和無線網(wǎng)絡(luò)認(rèn)證的無縫隙結(jié)合；信道的檢測(cè)與劃分。本文通過不斷測(cè)試和實(shí)踐，把認(rèn)證信息直接傳送到有線認(rèn)證服務(wù)器上等方式來解決網(wǎng)絡(luò)中身份認(rèn)證問題。對(duì)本文設(shè)計(jì)的校園無線網(wǎng)絡(luò)進(jìn)行了結(jié)果驗(yàn)證與分析，通過對(duì)信號(hào)強(qiáng)度、安全服務(wù)、認(rèn)證技術(shù)以及三層漫游的幾項(xiàng)驗(yàn)證，說明無線校園網(wǎng)絡(luò)的建設(shè)以及基本實(shí)現(xiàn)了本設(shè)計(jì)意圖，使得校園無線網(wǎng)絡(luò)能夠可信、可控、可用的投入使用。 通過學(xué)校無線網(wǎng)絡(luò)的實(shí)現(xiàn)，能夠?yàn)閷W(xué)校教職工和學(xué)生的工作、學(xué)習(xí)和生活帶來更加便利的網(wǎng)絡(luò)環(huán)境，使校園網(wǎng)絡(luò)的建設(shè)能夠提高工作效率，促進(jìn)學(xué)校的發(fā)展。
[Abstract]:With the continuous development of modern education in China, the construction of digital campus has been put on the agenda. In the construction of schools, no matter from teaching, learning or daily life, The need for wireless network is more and more urgent. In the course of setting up the traditional campus network, the cable network is generally built mainly, because of the stability of the cable network, so in the campus network design, Cable networks are usually used to transmit information. But with the improvement of people's living standards, mobile terminal devices such as smartphones, laptops and tablets are widely used in people's daily life. Cable networks can no longer meet the daily study and work of school staff and students. It shows that the bandwidth of the network is no longer the limitation of the wireless network, and the good network brings us the opportunity to use the wireless network, and the school also needs the construction of the wireless network urgently, so that the campus network can be fully utilized. This paper mainly combines the existing network technology and campus network environment, analyzes the shortcomings of campus network, puts forward a wireless scheme based on campus network, solves the blind spot of wired network routing, and divides wireless channel detection. The security authentication and management of wireless network, the requirement of wireless network, and so on. Under the framework of campus wired network, the topology of wireless network structure is designed, and the user VLAN(Virtual Local Area network is divided into two parts. According to the field investigation, the allocation method and implementation steps of wireless access point are designed. According to the security requirements of wireless network, this paper puts forward an authentication solution and its implementation in accordance with the campus network. In the research process, there are several technical difficulties: different authentication systems, different manufacturers, Seamless combination of wired network authentication and wireless network authentication; channel detection and division. The authentication information is transmitted directly to the wired authentication server to solve the problem of identity authentication in the network. The results of the campus wireless network designed in this paper are verified and analyzed. The authentication technology and several verification of three-layer roaming show that the construction of wireless campus network and the basic realization of this design intention make the campus wireless network credible controllable and usable. Through the realization of school wireless network, it can bring a more convenient network environment for the work, study and life of school staff and students, so that the construction of campus network can improve the working efficiency and promote the development of the school.
