Design And Implementation Of Intelligent Campus Infrastructure Of Sichuan Information Technology College

With the development of computer network technologies and applications,"Internet +education" has become a new trend of educational development.Meanwhile,the revolutionary impact of information technology on the development of education is pointed out at the national level,and it is attached great importance by various governments and departments.In the construction process of campus network,besides constructing various kinds of applications,the specifications and standards suitable for intelligent campus infrastructure have been raised to a new level.Taking the construction of intelligent campus infrastructure of Sichuan Information Technology College as the research carrier,the vision and urgent demand of the development of education informatization of the college is analyzed.And then,the intelligent campus infrastructure is designed.Guided by the principle of "unity" and "plat forming",and giving consideration to advanced,reliable,available,and security,a new architecture of college intelligent campus infrastructure is proposed,and the key technology problems are analyzed.The main contents of the thesis are as follow:(1)In the design of network architecture aspect,core layer Optimizing.Bold adjusting the network structure.Break the traditional pattern of using high performance and modules 3-layer switch as LAN core forwarding,high-performance,carrier-class router is used as core interaction device so as to support rich reliable technology.(2)In the research and application of virtualization technology aspect,the virtualization technology was used to build the Cloud Computing Center of our campus.The resource of computing and storage limit was resolved,and the Use efficiency was improved.(3)Planning the wireless network spreading all over the campus so as to create a ubiquitous learning,working and living environment,and to provide a free fast network environment for all types of applicant expandability,so as to completely solve the problems of compatibility and convocations promotion and online teaching.(4)In the analysis and application aspect,SDN technology is used to implement part virtualization of access servers.Constructing unified authentication system to construct a whole-campus-wide Portal authentication platform with high reliability,high performance nieces.(5 The gateway is used to manage and control the user behavior In order to avoid unnecessary trouble,besides making preparations from institution and ideological education,it is necessary to defense the network from technology level so as to make up man-defense+ machine-defense.
