【摘要】：在教育信息化的背景下,我国多数高校已经建立起了校园网络,师生对网络需求的不断提高。尤其近年来,移动终端如笔记本电脑、平板电脑、智能手机不断普及,对无线网络接入需求增大。特别是校园的会议室、操场、广场等室外活动场的网络接入需求,传统有线网络无能为力。无线网络具有很多优点,如速度高、布设简易、易于维护、灵活性强,师生通过的移动终端随时、随地与校园网络连接,不间断地访问校园网络资源进行工作和学习,广大师生日益把无线作为主要网络接入形式,规划建设校园无线网络重要性不言而喻。本论文以河南林业职业学院校园无线网络构建为例,先分析有线网络和无线网络的特点,无线网络是有线网络有益的补充,能极大地提高学院信息化和智慧校园的建设水平,提高学生和教职工的学习、工作效率。对照学院无线网络建设需求和设计原则,经过对校园网实地考察和分析,充分考虑学院现有网络的基础上,对学院的无线网络进行规划,画出修改后的网络拓扑,标注需要更改的网络结构。在本设计中使用Fit AP+AC组网模式,对所有的AP进行控制和管理,根据不同的地点和所要达到的预期效果确定根据实际需要的组网模式和组网设备。最后,针对无线存在安全隐患,对校园无线网络安全进行合理的规划与设计,涉及认证计费、空口安全和用户接入安全等,对校园网目标人群进行分类,设置3个不同的SSID号,对不同类型的用户设置不同的网络使用权限,并对网络进行自动调优、负载均衡和抗干扰的设计。整个无线网络使用室外和室内AP相结合的方法,充分考虑容量和使用者的流量需要,以实现网络的全覆盖为最终目标,有线无线管理相融合,简化网络运维管理,降低运维成本,最终将学院网络建成一个可靠性强、安全经济、可扩展,满足学院5-10年发展需求的校园网络,为学校的教学、管理信息化服务,提升学校整体实力。
[Abstract]:Under the background of educational informatization, most colleges and universities in our country have established the campus network, and the demand of teachers and students for the network is increasing. Especially in recent years, mobile terminals such as laptops, tablets, smart phones have been popularized, and the demand for wireless network access has increased. Especially in the campus meeting room, playground, square and other outdoor venues network access needs, traditional cable network is powerless. Wireless network has many advantages, such as high speed, easy to set up, easy to maintain, flexible, teachers and students through the mobile terminal at any time, anywhere to connect with the campus network, uninterrupted access to campus network resources for work and learning, Teachers and students increasingly regard wireless as the main form of network access, and the importance of planning and building campus wireless network is self-evident. Taking the campus wireless network construction of Henan Forestry Vocational College as an example, this paper first analyzes the characteristics of wired network and wireless network. Wireless network is a beneficial supplement to wired network and can greatly improve the construction level of college information and intelligent campus. Improve the study of students and staff, work efficiency. In contrast to the requirements and design principles of wireless network construction in college, through the field investigation and analysis of campus network, and taking full account of the existing network of the college, the wireless network of the college is planned, and the modified network topology is drawn. Note the network structure that needs to be changed. In this design, the Fit AP AC networking mode is used to control and manage all the AP. According to the different locations and expected results to be achieved, the networking mode and networking equipment are determined according to the actual needs. Finally, aiming at the hidden danger of wireless network security, the campus wireless network security is reasonably planned and designed, which involves authentication and billing, empty port security and user access security. The target population of campus network is classified and three different SSID numbers are set up. Different network permissions are set up for different types of users, and the design of network automatic tuning, load balancing and anti-interference is carried out. The whole wireless network uses the method of combining outdoor and indoor AP, fully considers the capacity and the user's traffic needs, takes the realization of the full coverage of the network as the ultimate goal, integrates the wired wireless management, and simplifies the network operation and maintenance management. By reducing the cost of operation and maintenance, the college network will eventually be built into a campus network with strong reliability, security and economy, which can be expanded to meet the needs of the college for 5-10 years, so as to serve the teaching and management information of the school, and to enhance the overall strength of the school.
