The campus network is a broadband multimedia network that provides teaching, scientific research and comprehensive information services to school teachers and students. First of all, the campus network should provide an advanced information-based teaching environment for school teaching and scientific research. This requires: the campus network is a broadband, interactive and professional local area network. Multimedia teaching software development platforms, multimedia demonstration classrooms, teacher lesson preparation systems, electronic reading rooms, and teaching and examination databases can all run on this network. If a school includes multiple professional disciplines (or multiple departments), multiple local area networks can also be formed and connected through wired or wireless methods. Secondly, the campus network should have academic, administrative and general affairs management functions.
Features:
1. High-speed LAN connection - the core of the campus network is the network for teachers and students within the campus, so the campus LAN is the focus of the system's construction , and network information contains a large amount of multimedia information, so large-capacity and high-speed data transmission is a basic requirement of the network;
2. Diversified information structure - campus network applications are divided into electronic teaching (multimedia Classrooms, electronic libraries, etc.), office management and remote communications (distance teaching, Internet access, FTP services, online games, etc.). The data types are complex, and different types of data have different quality requirements for network transmission;
3. Safe and reliable - there is also a large amount of important data about teaching and file management in the campus network, whether it is damaged, lost or If it is stolen, it will bring great losses;
4. Easy to operate and easy to manage - the campus network is large and the access is complex. Network maintenance must be convenient and fast, and the equipment network management must be strong to facilitate network failures. exclude.
5. Authentication and billing - schools must implement effective control and billing strategies for students' access to the Internet to ensure network utilization.
The campus network system is divided into core layer, aggregation layer and access layer from the structural level; from the functional point of view, it can be basically divided into campus network center, teaching subnet, office subnet, dormitory area subnet, Library subnet, etc. According to the number of campus network users and network applications, it can be divided into three types: large campus network, medium campus network, and small campus network. Based on the above characteristics of the campus network, we must fully consider the advancement, standardization and openness, reliability and availability, flexibility and compatibility, practicality and economy, security and confidentiality, and expansion of the network when designing the campus network. characteristics such as security and network flexibility, making full use of limited investment to build a cost-effective comprehensive network.
With the development of the economy and the implementation of the national strategy of rejuvenating the country through science and education, campus network construction has gradually become a school infrastructure project and an important symbol for measuring the informatization and modernization of a school's education. At present, most qualified schools have completed the construction of campus network hardware projects. However, for many years, the understanding of campus networks has not been comprehensive enough, and there are even big misunderstandings. For example, they believe that the more high-end network construction is better, blindly pursue high investment in construction, and lack comprehensive planning and development applications for campus network construction; they believe that building a campus network and connecting it to the Internet is equivalent to realizing the integration of teaching and office work. Automation and informatization, but lack of comprehensive management of campus networks, application training of technical personnel and teachers, lack of development and accumulation of teaching resources, etc. All of these have greatly hindered the actual benefits that campus networks should play in school management, education and teaching.
Overall design:
The design goal of the campus network is to connect various information resources of different applications to each other through high-performance network equipment to form an internal network within the campus area. The 12000/XPranet system is externally connected to the WAN through routing equipment.
First, it is necessary to conduct object research and demand survey, clarify the nature, tasks of the school and the needs and conditions for the construction of the main system for reform and development, and accurately describe the school's information environment;
Second, based on the application demand analysis, determine the school's 12000/XPranet service type, and then determine the goals of system construction, including network facilities, site settings, development applications and management goals;
Second Third, determine the network topology and functions, and conduct system analysis and design based on the application demand construction goals and the distribution characteristics of the school's main buildings;
Fourth, determine the principle requirements of technical design, such as technology selection, Standards and requirements for wiring design, equipment selection, software configuration, etc.;
Fifth, plan the implementation steps for campus network construction.
Basic functions:
It can be seen from the above analysis that campus networks and campus groups should provide a network environment for education between schools; realize resource sharing , information exchange, collaborative work and other basic functions.
1. Provide tools and network environment for the timely, accurate and reliable collection, processing, storage and transmission of educational information.
2. Provide basic data, means and network environment for school administrative management and decision-making, realize office automation, and improve work efficiency, management and decision-making levels.
3． Provide a network platform and environment for various teaching links such as lesson preparation, courseware production, teaching, learning, practice, tutoring, communication, examinations and statistical evaluation.
