Beijing Miyun District to create a new generation of education metropolitan area network

At present, it has become a broad consensus to promote education equity and improve education quality through informationization. In Miyun, a suburb of Beijing, 80% of primary and secondary schools in the whole district are located in mountainous areas. It is urgent to use information technology to “pave the way for education” and eliminate the problem of balanced education development of “a large number, a partial position and a scattered distribution”. To this end, the Miyun District Education Committee and the Ruijie Network have comprehensively upgraded the education metropolitan area network to quickly meet the changing application requirements with a powerful and feature-rich network infrastructure, which has well supported the teachers' online collaborative preparation of classes. Cross-regional network collaborative teaching and research and student network electives and other business smoothly.

Promote the education of wisdom, the basic network "can not help"

In order to eliminate geographical limitations and effectively improve the level of mountain education, the development of education informationization in Miyun District is determined as: to build multi-level, full coverage and intelligent education information with the core of building a “smart education” with urban and rural integration, high-quality balance and integration and innovation. System. Similar to the principle of “To be rich, to build roads first”, wisdom education must also run on the information highway. However, due to the early construction of the education metropolitan area network in Miyun District, it has become “incapable of supporting the teaching business innovation and operation and maintenance management”.

First of all, it is necessary to fully utilize the value of the cloud platform, further improve the educational resource sharing and sharing mechanism, realize the goal of teachers' online collaborative preparation, teaching, and cross-regional network collaborative teaching and research. The core backbone and export bandwidth of Miyun Education Metropolitan Area Network need to be further expanded. . However, the expansion of network bandwidth is not endless. It is necessary to use technical means to reduce the occupation of export traffic, and at the same time ensure the online experience of teachers and students in the whole district.

Secondly, network security management is related to the daily operation of each school business. It not only needs to deploy network real-name system, wired and wireless network unified authentication, but also prevent network virus infection or large-scale outbreaks, which will directly affect first-line classroom education and teacher preparation.

Finally, for many mountain schools, the lack of professional talent and capital investment, the operation and maintenance capabilities of the cable network is very limited, and after the deployment of the wireless network, the operation and maintenance pressure is even more arduous. Therefore, to ensure the normal operation of various education and teaching business systems, it is necessary to solve the manpower problem by deploying intelligent and unified operation and maintenance products.

The smart plan "pave the way to the countryside" to resolve the "three thresholds" for the upgrade of the metropolitan area network

After multi-party comparison, Miyun District decided to use the smart education metropolitan area network solution provided by Ruijie Networks to connect the subordinate schools to the backbone of the regional education metropolitan area network through optical fiber and dedicated lines, and uniformly deploy the wireless management platform in the data center of the district education committee. , identity authentication platform, content acceleration system, operation and maintenance management platform, etc., and then build a "full service, high security, easy to manage" metropolitan area network platform to better carry the application development of education and teaching in the area.

Three-level network high-speed interconnection, stepping through the bandwidth threshold

Through the transformation of the education metropolitan area network, the five core backbone nodes in the Miyun District are upgraded from 1G bandwidth to 20G, the aggregation switch is upgraded from Gigabit to the 10G backbone backbone area, and the campus network is all connected to the Miyun Education Metropolitan Area Network. The independent optical fiber Gigabit interconnection and the city information center 10 Gigabit connection realize the high-speed interconnection and intercommunication of the city, district and school three-level network. At the same time, by deploying the content acceleration system RG-PowerCache to localize the Internet hotspot resources, it can reduce the bandwidth pressure of 30%-50% during the peak of business access, effectively improving the online experience and saving the Internet bandwidth rental cost. Bandwidth is the threshold.

Multiple defense identity management, stepping through the security threshold

This upgrade enables the network to have strong defense capabilities by deploying security devices such as integrated security gateways, firewalls, and flow control. It can effectively defend against illegal activities such as hacker attacks, virus transmission, and malicious intrusion. In addition, Miyun also established a real-name identity management system and a wireless network authentication self-service platform, which can not only seamlessly roam, intervene access between schools, but also set granularity according to resource access rights (district level, School-level policy control, standardizes teachers and students to go online healthily, and conducts log audits of users' online behaviors to facilitate future traceability. These targeted program measures have allowed the security threshold to pass.

Unified management and hierarchical maintenance, stepping through the operation and maintenance threshold

Finally, in the face of the “gate” of operation and maintenance management, Ruijie Networks combines the information center and the specific needs of each school, and adopts the RIIL integrated service operation and maintenance platform to realize integrated management of the education network resources of the whole district. On the basis of unified management and hierarchical maintenance, the complexity of separate management of wireless network and wired network is greatly reduced, and users can control the comprehensive health level of IT resources in real time, and deal with the faults of wireless and wired networks in the first time to ensure cloud platform and Teaching and research exchanges work smoothly.

The process of regional education informatization construction is a process of continuously discovering problems and crossing obstacles. It is also a process from decision makers, managers to teachers that need to update concepts, unify understanding, and constantly work together. After the successful implementation of the education metropolitan area network reconstruction project, Miyun District became the backbone node of the Beijing Education Information Network. Through the further construction of the education cloud service platform and the application building based on the wireless network smart classroom, Miyun has made remarkable achievements in exploring the concept of “Internet + education” and promoting the improvement of education and teaching. On the road of “integration of urban and rural areas, quality and balance” Constantly accelerating.
