【摘要】：校园网是每一所学校必备的基础设施,在校教职工和学生几乎每人至少拥有一台带有Wi-Fi功能的手机或笔记本电脑等,在信息时代,老师和学生经常需要在互联网上查询资料,校园网成为师生工作、学习和生活必不可少的一部分。本文以郑州某中职院校校园网为例,分析了该学院校园网目前存在的问题,提出了在全校范围内建设无线网络的需求,并进行了设备选型,地理勘察,选择协议标准,确定组网模式等,为项目实施奠定基础;然后针对学校的具体情况进行了无线网络的规划、设计和实施;接着介绍了无线网的认证计费系统。整个无线网络建设时以覆盖为主,同时考虑容量需求,结合SUM和EPORTAL服务器进行无线管理,通过无线控制器对室内和室外AP进行分布系统建设,完成校园网的建设;最后对整个网络进行了相关测试。项目投入使用后,全网运行稳定,各项指标达到了设计目标。全校师生可以利用自己的用户名和密码进行无线网络认证,教师利用网络资源进行备课,学生课上跟随教师讲授的思路,课下利用网络对知识点进行复习巩固,为学校的教育信息化工作提供了有力的支撑。中职院校网络基础设施薄弱,资金预算有限,建设一个快速、稳定、高效的校园网,设备选型成为整个设计规划中必须要考虑的因素,本文在无线设备选型方面做了详细阐述,对有建设无线校园网需求的院校有一定的借鉴意义。
[Abstract]:Campus network is an essential infrastructure for every school. Almost every faculty and student has at least one mobile phone or notebook computer with Wi-Fi function in the information age. Teachers and students often need to look up information on the Internet, the campus network has become an essential part of the work, study and life of teachers and students. This paper takes the campus network of a secondary vocational school in Zhengzhou as an example. This paper analyzes on the problems existing in the campus network of the college, puts forward the requirement of constructing wireless network in the whole school scope, and carries on the equipment selection, the geographical survey, the selection of protocol standard, the determination of the networking mode and so on. Laying the foundation for project implementation; Then according to the specific situation of the school, the wireless network planning, design and implementation; Then it introduces the wireless network authentication and billing system. The whole wireless network construction is mainly overlay, while considering the capacity requirements, combined with SUM and EPORTAL server to carry out wireless management. The indoor and outdoor AP distribution system is constructed by wireless controller to complete the construction of campus network. Finally, the whole network is tested. After the project is put into use, the whole network runs stably, each index reaches the design goal. The whole school teachers and students can use their user name and password to carry on the wireless network authentication. Teachers make use of network resources to prepare lessons, students follow teachers' teaching ideas in class, and use network to review and consolidate knowledge points under class. The network infrastructure of secondary vocational colleges is weak, the capital budget is limited, and a fast, stable and efficient campus network is built. The selection of equipment has become a factor that must be considered in the whole design planning. This paper makes a detailed elaboration on the selection of wireless equipment, which has certain reference significance for colleges and universities with the requirement of building wireless campus network.
