【摘要】：伴隨著我國現(xiàn)代化教育事業(yè)的不斷發(fā)展，數(shù)字化校園的建設被提上了議事日程。在學校的建設中，無論從教學、學習還是日常生活，都已經(jīng)越來越離不開校園網(wǎng)絡。而在這其中，當前對于無線網(wǎng)絡的需要更顯的尤為迫切。 在傳統(tǒng)的校園網(wǎng)絡的架設過程中，一般都是以有線網(wǎng)絡的架設為主，因為有線網(wǎng)絡所具備的穩(wěn)定性優(yōu)點，使得在校園的網(wǎng)絡設計中，通常都是采用有線網(wǎng)絡來實現(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、筆記本電腦和平板電腦等移動終端設備在人們的日常生活中大量普及，有線網(wǎng)絡已經(jīng)無法滿足學校教職工和學生的日常的學習和工作。當前4G網(wǎng)絡興起和普及，表明網(wǎng)絡的帶寬已經(jīng)不再是無線網(wǎng)絡的限制。良好的網(wǎng)絡帶給了我們利用無線網(wǎng)絡的時機，學校也急需通過無線網(wǎng)絡的建設，使校園網(wǎng)絡能夠獲得充分的利用。 論文主要結合學�，F(xiàn)有的網(wǎng)絡技術和校園網(wǎng)絡環(huán)境，分析出校園網(wǎng)絡的不足之處，，提出一個基于校園網(wǎng)絡的無線方案，解決了對于有線網(wǎng)絡布線的盲點；無線信道檢測劃分；無線網(wǎng)絡的安全認證和管理；用戶對無線網(wǎng)絡需求等一系列的問題。在校園有線網(wǎng)絡的架構下，設計了無線網(wǎng)絡結構拓撲；對用戶VLAN（Virtual Local Area Network）和管理VLAN進行劃分，對核心交換機進行配置；根據(jù)現(xiàn)場勘察，設計了無線接入點的分配方法以及實施步驟；根據(jù)無線網(wǎng)絡的安全性需求提出了一個符合校園網(wǎng)的認證解決方案以及具體實現(xiàn)。在研究過程中，存在幾個技術難點：不同認證系統(tǒng)，不同的廠家，有線網(wǎng)絡認證和無線網(wǎng)絡認證的無縫隙結合；信道的檢測與劃分。本文通過不斷測試和實踐，把認證信息直接傳送到有線認證服務器上等方式來解決網(wǎng)絡中身份認證問題。對本文設計的校園無線網(wǎng)絡進行了結果驗證與分析，通過對信號強度、安全服務、認證技術以及三層漫游的幾項驗證，說明無線校園網(wǎng)絡的建設以及基本實現(xiàn)了本設計意圖，使得校園無線網(wǎng)絡能夠可信、可控、可用的投入使用。 通過學校無線網(wǎng)絡的實現(xiàn)，能夠為學校教職工和學生的工作、學習和生活帶來更加便利的網(wǎng)絡環(huán)境，使校園網(wǎng)絡的建設能夠提高工作效率，促進學校的發(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.
