[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.
