校园网升级改造方案的设计与实施——以高职校园为例

摘要随着社会的不断发展和计算机技术的快速提升，为了进一步提升高职院校网络水平，将对学校网络展开改造实施工程。本次网络升级改造工程将采取科学、规范、严谨的实施工作方式，确保工程质量和效果。本课题的目标是为老师和学生提供更全面的网络服务，以协助学校提高教学水平和研究能力。通过分析原校园网的现状与存在的问题并结合院校需求将拓扑网络进行了全新的设计和规划，采用了更为合适的三层网络结构，对核心设备（交换机和防火墙）进行更新换代。校园网改造提升了新旧设备的兼容性。解决了服务器运维难度大的问题，提升了设备管理水平和数据可靠性。针对设备数量增多导致机房不足的问题，对新教学楼进行设备选材和对旧教学楼进行更换设备。同时建设数据中心机房并列举出选材清单。当校园网的改造计划付诸实施后，对实施效果分析可知网络的安全性和可依赖性大大增强，整个校园网络的运行也变得更加健康有序。总的来说，这个升级计划的实施结果是令人满意的。关键词：校园网；方案改造；防火墙；网络安全AbstractNumerous new technologies are continually being highlighted as a result of the rapidadvancement of computer technology and the ongoing growth of society.We will upgradeGigabit access over wired networks and streamline the campus network architecture inorder to keep up with the rising network demand.This will greatly increase networkefficiency and performance,including access speed and reliability.The ultimate objectiveof this topic is to offer teachers and students more comprehensive network services and toencourage the development of a digital campus information infrastructure in order to assistschools in raising the calibre of their instruction and research capabilities and therebybetter serve society and the economy.In this essay,a campus network for higher education is examined.The topologicalnetwork has been entirely built and planned after analysing the present state and existingissues of the original campus network and combining with the needs of colleges anduniversities.To modernise the switch and firewall fundamental components,a three-layernetwork topology is implemented.The compatibility of new and old devices has improvedas a result of the campus network's transition.It fixes the issue of challenging serveroperation and upkeep and raises the bar for equipment management and data dependability.The equipment materials of the new teaching building are chosen to replace the equipmentof the old teaching building due to the lack of computer rooms brought on by the growthin technology.A data centre computer room is constructed at the same time,and a list ofmaterial options is presented.The examination of the implementation effect reveals thatthe security and dependability of the network have been significantly improved,and theoperation of the entire campus network has become healthier and more organised.Theoutcomes of this improvement plan's implementation are remarkable overall.Keywords:transformation plan;network security;campus network;firewall目录1绪论.1.1研究背景及意义1.1.1研究背景1.1.2研究意义与目的1.2国内外研究现状.21.2.1国外研究现状…21.2.2国内研究现状21.3研究方法…31.4研究内容…41.5研究架构.41.6本章小结…52相关技术介绍62.1多核心技术.62.2虚拟局域网技术..62.3防火墙技术72.4三层交换技术82.5本章小结.83高职校园网络现状研究及需求分析93.1高职校园网发展.93.2高职校园网络结构现状.93.3校园网存在问题分析..103.3.1网络的基础设施和网络安全的担忧113.3.2控制服务器和保护数据.113.3.3中央机房较陈旧.113.4校园网总体需求分析.123.5网络改造目标.123.6校园网改造原则.133.7本章小结.….144高职校园网络升级改造方案的设计154.1规划设计…154.1.1网络拓扑规划….154.1.2技术方案规划.154.1.3P地址规划.16川
