【摘要】：当今世界，科学技术飞速发展，给人们的生活带来了深远影响，极大改变着我们的生活方式。计算机网络技术的迅猛发展，渗透到了我们生活的各个方面。随着网络技术的逐步普及，作为实践技能推广、普及的中等职业学校，建立一个运行可靠、经济实用的学校园区网，提高学校教学质量、改善教师工作环境成为不二选择。校园网网络系统不仅为现代化教学、综合管理和办公自动化等应用提供基本操作平台，还能提供多种应用服务，使信息得到及时收集、及时反馈、及时利用。随着信息化技术的飞速发展，教学管理对计算机应用系统的依赖性增强，计算机应用系统对网络的依赖性增强。计算机网络规模不断扩大，网络结构日益复杂。计算机网络和计算机应用系统的正常运行对网络安全提出了更高的要求。信息安全防范应做整体的考虑，全面覆盖信息系统的各层次，针对网络、系统、应用、数据做全面的防范。信息安全防范体系模型显示安全防范是一个动态的过程，事前、事中和事后的技术手段应当完备，安全管理应贯穿安全防范活动的始终。校园网的建设可以为学校的教学、科研及管理提供一个信息应用平台。本文提出了一个基于标准的结构化计算机网络的校园网并讨论了实现该系统工程的技术，以更好地为中等职业技术学校计算机网络系统建设提供指导。本文首先就呼伦贝尔职业技术学校校园园区网的规划、构建所需的相关知识、技术、要求作了必要的介绍，研究了当今流行的网络设计方法、网络互连手段和当今局域网技术。然后基于工程建设实际，实地调研，对本校园区网的需求做了分析。论文从用户的需求分析入手，通过对主干网组网技术、网络拓朴结构、方案总体设计的讨论，，重点对校园园区网整体解决方案、校园网网络拓扑、核心网设计及IP地址分配、网络安全等方面进行了比较详细的分析与描述，并给出具体的实施方案和设备选型。本毕业设计课题主要以呼伦贝尔职业技术学校校园局域网络建设过程的实施方案为设计方向，为校园网的建设提供理论依据和实践步骤。
[Abstract]:In today's world, the rapid development of science and technology has brought a profound impact on people's lives, greatly changing our way of life. The rapid development of computer network technology permeates all aspects of our life. With the gradual popularization of network technology, it is necessary to establish a reliable, economical and practical school park network to improve the teaching quality and teachers' working environment. The campus network system not only provides the basic operating platform for modern teaching, comprehensive management and office automation, but also provides a variety of application services, so that the information can be collected, feedback and utilization timely. With the rapid development of information technology, the dependence of teaching management on computer application system and the dependence of computer application system on network are strengthened. The scale of computer network is expanding and the network structure is becoming more and more complex. The normal operation of computer network and computer application system puts forward higher requirements for network security. Information security should be considered as a whole, covering all levels of information system, aiming at network, system, application and data. The model of information security prevention system shows that security prevention is a dynamic process. The technical means of pre-, in-process and post-event should be complete, and the security management should always run through the activities of security prevention. The construction of campus network can provide an information application platform for school teaching, scientific research and management. This paper presents a campus network based on the standard structured computer network and discusses the technology of realizing the system engineering in order to provide better guidance for the construction of computer network system in secondary vocational and technical schools. In this paper, the planning of campus network of Hulunbeir Vocational and Technical School, the necessary knowledge, technology and requirements for constructing campus network are introduced, and the popular network design method, network interconnection means and current LAN technology are studied in this paper. Then, based on the engineering practice and field investigation, the requirements of campus network are analyzed. Based on the analysis of the users' needs, the paper discusses the backbone network technology, network topology and the overall design of the scheme, focusing on the campus network overall solution, campus network topology, core network design and IP address allocation. Network security and other aspects are analyzed and described in detail, and the specific implementation scheme and equipment selection are given. This graduation design project mainly takes the implementation plan of campus local area network construction process of Hulunbeir Vocational and Technical School as the design direction, and provides the theoretical basis and practical steps for the campus network construction.
