辽宁工业大学本科生毕业设计论文.docVIP

摘 要 随着网络建设的逐步普及，高校校园网络的建设是高校向高水平研究性大学跨进的必然选择，高校校园网络系统是一个非常庞大而复杂的系统，它不仅为高校的发展、综合信息管理和办公自动化等一系列应用提供基本操作平台，而且能够使教育、教学、科研三位一体，提高教育教学质量。 论文从辽宁大学校园网的需求分析入手，以局域网络以太网技术为基础，阐述了如何建一个信息化校园的园区网络。设计包括，校园网的网络设计，网络设备的选型，网络安全设计，网络存储设计，综合布线系统设计。网络设备选型选择在校园网设计中最受欢迎的华为三层交换机，既能满足校园网的需要，又有良好的拓展能力。网络安全设计采用硬件防火墙，与硬盘保护卡双重保护模式，在有效的阻止非法攻击的同时还能对重要数据进行加密与恢复。综合布线系统设计采用流行的水平加垂直布线方法，布线节省线材，外观美观。另外，在应用系统方面，设计了数字化图书馆系统、办公自动化系统、“校园一卡通”系统等。 网络中心是整个校园网的中心区域，良好的设计可以使校园网稳定长久的运行下去，所以网络中心的设计就由为重要，本方案建立了一个防尘，防静电，通风，能控温，供电稳定的网络中心。 关键词：校园网；网络结构设计；综合布线；网络安全 Abstract With the gradual popularization of the network construction, the construction of campus network is the inevitable choice of university to a high level of university entered, campus network system is a very huge and complicated system, it not only provides the basic platform for the development of colleges and universities, integrated information management and office automation and so on a series of applications, but also can make education, teaching, scientific research and the Trinity, improve the quality of education and teaching. The article sets out from the requirement analysis of the Liaoning University campus network, takes the LAN Ethernet technology as a foundation, elaborates how to constructs an informationization campus network. The design includes, the campus network design, the network equipment selection, the network security design, The network storage system，the comprehensive wiring system design. The network equipment selection is layer-3 switching that is popular in the campus network design, both can satisfy the requirement of the campus network and has the good development ability. The network security design uses the dual protected mode that the hardware firewall and the hard disk protection card, can carry on the encryption and the restoration of the important data, effectively prevent illegal attack simultaneity. The comprehensive wiring system design uses the popular method that the horizontal wiring adds to the vertical
