Beijing Elementary School-the only elementary school named "Beijing" in the capital of the People's Republic of China, was born on June 19, 1949. It is the largest public boarding school established by the Beijing Municipal Committee in the early days of the founding of the People's Republic of China. The school covers an area of ​​19,000 square meters, with a construction area of ​​38,000 square meters. The school currently has 39 teaching classes, 1537 students, and has a group of outstanding middle-aged and young backbone teachers.
Beijing Elementary School has outstanding achievements in scientific research, and has undertaken national and municipal educational scientific research experimental projects. It has achieved outstanding results in the research of subject education, personalized development education, art activities, campus culture construction and new learning models. It has been continuously rated as an advanced school of scientific research in Beijing, and the quality of running a school enjoys a high reputation in the society, and it is called "the cradle of hope".
With the country's continuous emphasis on education and the society's efforts to promote education, schools are under unprecedented pressure. This pressure has accelerated the school's search for more methods and opportunities to improve and perfect its own teaching management. To this end, Beijing Elementary School decided to carry out modern campus network construction, use modern technology equipment and network software resources, update education concepts, and change the traditional education teaching mode and learning method, thereby maximizing the teaching management level and teaching quality. At the same time, after the network is completed, it can meet the network requirements of digitalization, all-weather, non-blocking, large capacity and high efficiency.
According to the school's network construction goals and specific needs, Tongfang Network has proposed a corresponding Gigabit Ethernet solution, which has been highly recognized and adopted by the school. This solution not only has the necessary reliability, stability and security of the general network. When selecting products, it gives priority to the special requirements of the campus network, that is, the high bandwidth and QoS guarantee required by its multimedia. In addition, due to the financial constraints of the school, how to reserve expansion space and carry out investment protection to meet the needs of the growth and change of information volume was also considered in the design of the solution.

The core of the program uses 1000M exchange, the terminal uses 10 / 100M Ethernet access, and connects to the Internet at the same time. The specific solution is as follows:
1. The core switch uses Tsinghua Tongfang's TFS9014E layer 3 switch, which is a powerful backbone switch that can provide wire-speed switching and layer 3 routing for enterprise applications. Built-in management agent and global routing engine, and equipped with 14 expansion slots to insert a variety of media modules or local routing engines, up to 96 100M Fast Ethernet ports or 24 Gigabit ports. This switch can integrate all 10M / 100M / 1000M Ethernet devices to fully protect the existing network investment. This switch also has excellent performance unmatched by traditional routers, and can provide wire-speed layer 3 switching capability for the IP protocol.
2. The terminal switch uses Tsinghua Tongfang's TFS7124ES + stacked network management switch, which can provide 24 10 / 100M ports, and additional 2 slots that support optional expansion module slots and optional expansion or stacking modules. This system provides 100BASE-FX 100Mbps fiber optic module, 1000BASE-SX / LX / T Gigabit uplink module, and stacking module that allows 8 switches to be connected to a common backplane. It can work with all existing Ethernet and Fast Ethernet equipment and cables, and it is easy to manage and easy to configure, ensuring the user's investment in the network to the greatest extent.
Since the nationwide large-scale "school-school communication" project was launched in 2001, in just two or three years, the construction level of primary and secondary school campus networks has been significantly improved, and some new application trends have gradually emerged. Especially in some campus network projects implemented recently, by concentrating the functions of multiple network devices on a core switch in the past, the network structure is simplified, performance is enhanced, and equipment costs are greatly saved. The application of Tsinghua Tongfang intelligent campus network equipment in Beijing Elementary School is such a typical case. Since then, Beijing Elementary School can meet the needs of e-mail, Internet browsing, FTP transmission, etc., electronic classroom, electronic library, electronic classroom preparation room, campus network office The system and the distance learning system are supported by a very solid network platform.
