The school network is also called the campus network and is a local area network. The campus network should provide an advanced information-based teaching environment for school teaching and scientific research; this requires that the campus network be a broadband, interactive and professional local area network.
The campus network is a broadband multimedia network that provides teaching, scientific research and comprehensive information services to school teachers and students.
Campus network is a computer network within the school that provides resource sharing, information exchange and collaborative work for school teaching, scientific research, management and other education under the guidance of certain educational ideas and theories.
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 classroom , electronic library, etc.), office management and remote communication (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.
