Network background

The informatization of education is one of the important thoughts of education reform in today's world. It is the requirement of the times and the requirement of quality education. The Renmin University of China, located in Zhongguancun, Haidian District, Beijing, has vigorously implemented modern educational technology projects since 1997, and then carried out the first upgrade in 2000. Until the end of November last year, the National People ’s Congress will use Cisco ’s core switches to complete the campus network. The third upgrade has truly realized the modernized teaching environment of the 21st century-with scientific research as the leader, computer network as the basis, library and audio-visual center as the information source, and digitization as the model to improve the grade and quality of school education and teaching . At present, the entire campus network of the National People's Congress has been successfully upgraded to a 10 Gigabit backbone network, and the bandwidth to all buildings is gigabit, and the bandwidth to the desktop will also reach 100 megabytes. The entire campus network has more than 23,000 information points, using more than 1040 access layer switches, core switches and routing equipment; basic application servers and other types of application servers up to more than 100 (including Cisco, Huawei and Digital China) And other products from multiple manufacturers). The bandwidth from the campus network to the external network is the Gigabit export of China Education and Research Network and the 100M export of China Netcom.

In addition to the infrastructure, the school has established different public application systems and professional application systems in teaching, scientific research and management: office automation, undergraduate management system, graduate management system, school personnel management system, electronic school affairs Core applications such as systems, scientific research management systems and student management systems. These systems provide electronic information and network technical services for teaching, research, management, and the work and life of teachers and students throughout the school.

However, with the rapid development of its own business and the continuous expansion of the network scale, the abnormal use of the network by internal teachers and students has caused problems such as the shortage of network resources. The relevant personnel of the campus network management center are increasingly burdened with daily network implementation, management, analysis and upgrade; Not only that, worms, hackers, password eavesdropping, denial-of-service attacks, etc. that are everywhere on the Internet have also brought new challenges and burdens to managers. All of the above have brought various hidden dangers to the normal operation of the campus network and even directly threatened the normal education schedule. Therefore, how to ensure the normal and safe operation of the campus network, and to give the teachers and students a stable and high-quality network basic platform has become an important aspect of the campus network informatization process.

In the face of the above problems, the relevant leaders of the Network Management Center of the National People's Congress decided to take precautions. After many studies and technical discussions with the school's standing committee and industry peers, given the large campus network, the variety of equipment, the complex terminal applications and the very heavy management work, Decided to purchase an efficient and practical network management tool that can support many network equipment manufacturers to help administrators participate in the development of campus information construction and application development of digital technology.
