【摘要】：随着计算机网络技术及应用的快速发展,"互联网+教育"成为新常态,基于网络的信息化教学成为教育发展的新趋势。与此同时,国家层面也通过不同的方式指出信息技术对教育发展具有革命性影响,各级政府、各部门都予以了高度重视。在校园网络建设过程中,除建设各类应用外,建设与之发展相适应的智慧校园基础设施建设的规格、标准都提高到了一个新的高度。本论文以四川信息职业技术学院智慧校园基础设施建设为研究载体,通过分析学院在发展教育信息化的愿景和迫切需求,进而展开学院智慧校园基础设施建设设计,以"统一性"、"平台化"原则为指导,兼顾系统建设先进、可靠、可用与安全性,提出了学院智慧校园基础设施的新架构,分析解决了其中的关键技术问题。本文的主要内容如下:(1)在网络构架设计方面,通过优化核心层,大胆调整网络结构,打破传统上以高性能、模块化三层交换为主的局域网核心层高速转发的模式,取而代之的使用高性能、电信级路由器为核心交互设备并且支持丰富的可靠性技术。(2)虚拟化技术研究与应用。采用虚拟化技术,完成云计算机中心建设,解决了预算和存储资源紧张的问题,同时提高了设备利用率。(3)规划全校无线覆盖,以打造无处不在的学习、工作和生活环境,为各类应用推广和在线教学提供"零流量、零费用"的快捷网络环境。(4)SDN技术分析与应用。采用SDN技术,实现接入服务器部分虚拟化,构造认证系统,打造具有高可靠、高性能、扩展性强的全校统一 Portal认证平台,彻底解决兼容性和便利性问题。(5)采用网关进行用户上网行为管理和控制。为了避免一些不必要的麻烦,除了从管理制度上和思想教育做足准备外,同时从网络技术层面出发,做好网络防御工作,使得"人防+技防"相得益彰。
[Abstract]:With the rapid development of computer network technology and application, "Internet education" has become a new normal, network-based information teaching has become a new trend of education development. At the same time, the national level also points out in different ways that information technology has a revolutionary impact on the development of education, and all levels of government and departments have attached great importance to it. In the process of campus network construction, in addition to the construction of various applications, the construction of intelligent campus infrastructure construction standards and standards have been raised to a new level. This paper takes the intelligent campus infrastructure construction of Sichuan Institute of Information Technology as the research carrier, through analyzing the vision and urgent needs of the college in the development of educational informatization, and then launching the intelligent campus infrastructure construction design of the college. Under the guidance of the principles of "unity" and "platformization", and taking into account the advanced, reliable, usable and secure system construction, this paper puts forward a new structure of the intellectual campus infrastructure of the college, and analyzes and solves the key technical problems. The main contents of this paper are as follows: (1) in the aspect of network architecture design, by optimizing the core layer and adjusting the network structure boldly, we can break the traditional mode of high performance, modularized three layer switch, which is the mode of high speed forwarding in the core layer of LAN. Instead, it uses high-performance, carrier-grade routers as the core interactive devices and supports a wealth of reliability technologies. (2) Virtualization technology research and application. Using virtualization technology, the construction of cloud computer center is completed, the problem of budget and storage resources is solved, and the utilization ratio of equipment is improved. (3) the wireless coverage of the whole school is planned to create the ubiquitous learning, working and living environment. This paper provides a fast network environment of "zero flow, zero charge" for all kinds of application promotion and online teaching. (4) Analysis and application of SDN technology. SDN technology is used to realize partial virtualization of access server, construct authentication system, and build a unified Portal authentication platform with high reliability, high performance and strong expansibility. Thoroughly solve the compatibility and convenience problem. (5) use the gateway to manage and control the user's Internet behavior. In order to avoid some unnecessary troubles, apart from making sufficient preparations from the management system and ideological education, at the same time, from the network technology level, we should do a good job of network defense, so that "civil air defense" can complement each other.
