【摘要】：伴随着我国现代化教育事业的不断发展，数字化校园的建设被提上了议事日程。在学校的建设中，无论从教学、学习还是日常生活，都已经越来越离不开校园网络。而在这其中，当前对于无线网络的需要更显的尤为迫切。在传统的校园网络的架设过程中，一般都是以有线网络的架设为主，因为有线网络所具备的稳定性优点，使得在校园的网络设计中，通常都是采用有线网络来实现信息的传输。但是随着人们生活水平的不断提高，智能手机、笔记本电脑和平板电脑等移动终端设备在人们的日常生活中大量普及，有线网络已经无法满足学校教职工和学生的日常的学习和工作。当前4G网络兴起和普及，表明网络的带宽已经不再是无线网络的限制。良好的网络带给了我们利用无线网络的时机，学校也急需通过无线网络的建设，使校园网络能够获得充分的利用。论文主要结合学校现有的网络技术和校园网络环境，分析出校园网络的不足之处，，提出一个基于校园网络的无线方案，解决了对于有线网络布线的盲点；无线信道检测划分；无线网络的安全认证和管理；用户对无线网络需求等一系列的问题。在校园有线网络的架构下，设计了无线网络结构拓扑；对用户VLAN（Virtual Local Area Network）和管理VLAN进行划分，对核心交换机进行配置；根据现场勘察，设计了无线接入点的分配方法以及实施步骤；根据无线网络的安全性需求提出了一个符合校园网的认证解决方案以及具体实现。在研究过程中，存在几个技术难点：不同认证系统，不同的厂家，有线网络认证和无线网络认证的无缝隙结合；信道的检测与划分。本文通过不断测试和实践，把认证信息直接传送到有线认证服务器上等方式来解决网络中身份认证问题。对本文设计的校园无线网络进行了结果验证与分析，通过对信号强度、安全服务、认证技术以及三层漫游的几项验证，说明无线校园网络的建设以及基本实现了本设计意图，使得校园无线网络能够可信、可控、可用的投入使用。通过学校无线网络的实现，能够为学校教职工和学生的工作、学习和生活带来更加便利的网络环境，使校园网络的建设能够提高工作效率，促进学校的发展。
[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.
