The Ministry of Education and six other departments recently issued the Guidelines on Promoting the Construction of New Education Infrastructure and Building a High-quality Education Support System, proposing that by 2025, a new education infrastructure system with optimized structure, intensive efficiency, safety and reliability will be basically formed. According to the guideline, information network is one of the six key directions in the new education infrastructure. A private education network connecting schools and educational institutions at all levels should be built to improve the quality of school network and provide high-speed, convenient, green and safe Internet services.
In order to explore the way of the construction of education private network and tamp the digital base of the "Internet + education" platform, Ruijie recently held the "gathering the light of intelligence to build the digital Base of Education Development" education private network exchange meeting. And invited the Ministry of Education Education Information and network security Department, Jiangxi Province Education Technology and equipment development center, Shandong Qingzhou Education and sports Bureau, Chongqing Education Technology installation Center information technology Department related leaders and experts on the topic of "education private network construction" to carry out discussion, let's listen to what they said.
Information Networks: The cornerstone of a new infrastructure of education
"Information network, platform system and trusted security are the foundation and digital base to support the development of education informatization. As the first link in the construction of new education infrastructure, information network infrastructure is mainly composed of the national backbone network, provincial and municipal education network and campus network three network", the Ministry of Education education informatization and network security Department said.
The new education infrastructure includes the development direction of information network, platform system, digital resources, smart campus, innovative application and reliable security. The "new" of China's new education infrastructure is mainly reflected in three aspects: new connotation, new technology and new mechanism. As one of the key directions of education "new infrastructure" construction, information network puts forward corresponding requirements for the construction of "education private network" and "campus network" :
Network Construction, Cloud Formation and Application: Jiangxi Education Provincial Network "Proofing" for New Education Infrastructure
In the process of the development of education informatization, Jiangxi Province has encountered some problems that need to be solved urgently: the school network broadband cannot be guaranteed, and the Internet delivery class is difficult to be used regularly; Low level of cross-district and cross-school educational resource sharing; Operation and maintenance occupy a large number of manpower, teachers encounter information technology problems can not be effectively supported; Cost a lot of money to build IDC room running cost is high. In order to solve these problems, Jiangxi Provincial Department of Education has put forward the development idea of building network, organizing cloud and grasping application.
Tang Xu, director of Jiangxi Provincial Education Technology and Equipment Development Center, said that the construction of Jiangxi provincial education network is divided into backbone network, municipal MAN, county man and campus network. Practice has proved that, based on the achievements of Jiangxi Provincial Education Network and Jiangxi Education Cloud construction, Jiangxi Province has not only realized the classroom teaching class communication, class network bandwidth up to 100 megabytes, realized the cross-regional and cross-school sharing of various applications and high-quality education resources, but also greatly promoted the innovation and development of the application of education informatization. It has launched a series of innovative information-based teaching applications such as "Jiangxi Teaching Cloud Teaching Link", "Jiangxi Teaching cloud live streaming Service" and intelligent homework.
Building roads and building networks to Get Rich: The Last Mile of Teaching in Qingzhou, Shandong
How to solve the "last mile" problem of teaching, so that every classroom, every class as the battlefield of education has the best equipment? How to solve the "gas station" problem of teachers, let teachers use good equipment, make management easy and feasible? Ma Shiguo, director of the Education and sports bureau in Qingzhou city, Shandong Province, said, "If you want to get rich, build roads first. If you want to use it well, first build the network."
Qingzhou City to expand capacity, speed up, security, simple operation and maintenance of the idea of building the fifth generation of education MAN. By the end of 2019, Qingzhou completed the upgrading of education MAN, the backbone network expanded to double gigabit, school export expanded to double gigabit bare fiber, Internet export increased to ten gigabit, education MAN covers all primary and middle schools in the city. In terms of security, a comprehensive gateway EG is deployed at the exit of each school to link other security products to build a MAN in line with the requirements of network security law and equal protection 2.0, to build an active defense system under the requirements of the new era. At the same time, Qingzhou City has also established a central platform serving the whole city's education management and teaching informatization data, and constructed a central database of education identity standards to provide unified identity services for management and teaching applications.
"Minimalist Ethernet all-optical network" favored: Chongqing accelerated upgrading of primary and secondary school campus network
Due to the popularization and application of various business information systems in the school, three classes, distance teaching, information teaching and research, and management training are further promoted. The new demands of blowout need a high-speed, stable, safe and low-delay network to realize the support. In 2019, Chongqing vigorously promoted the construction of all-optical network. And start operator FIRST optical network scheme and GPON campus network scheme pilot.
With the iterative evolution and continuous increase of primary and secondary school campus business, the demand for high bandwidth and low delay of various teaching applications is growing day by day. In order to solve the needs of high broadband business expansion and operation and maintenance difficulties, some schools in Chongqing adopted Ruijie minimalist all-optical network scheme in 2020. Sun Weiyu, director of Information Technology Department of Chongqing Education and Technology Installation Center, said that the very simple light program combines the advantages of traditional Ethernet and GPON network, and realizes the advantages of "one room and one fiber, enjoying high bandwidth", "easy maintenance, quick user access" and "centralized management, intelligent simple operation and maintenance", which can better support the development of high broadband services in schools and the expansion of new services.
Ruijie 1+3S: tamping the foundation of education "new infrastructure"
What kind of education private network can meet the needs of education business? How can this private network ensure the stable operation, security and reliability of the business and convenient operation and maintenance? Tu Huainian, solutions manager of the general education industry Department of Ruijie Network, said that the increase in educational applications, the policy requirements of the Ministry of Education for IPv6 construction and the construction of smart campuses have put forward higher requirements for the construction of private education networks. Based on this, Ruijie 1+3S education private network solution came into being.
1 network (1 all-optical network) : The school accesses the education metropolitan area network of the respective district and county, and then accesses the provincial backbone ring network after the aggregation of the municipal backbone ring network. To improve the reliability of education private network through equipment, line redundancy, ring networking, so as to build a high speed and reliable education private network. The entire education private network supports both IPv6 and v4, providing support for the smooth evolution of the next-generation Internet. The construction of smart campus is supported by Ruijie ultra-simple optical Ethernet all-optical network, and optical fiber into class, flexible expansion of business and bandwidth, to meet the growing needs of smart campus business.
3S - Stable: All services are transmitted on the same network. If a virus or attack occurs on one service, other services are affected. At the same time, large bandwidth, interactive teaching requires low delay, and teaching conference requires low jitter, how to ensure these services? Ruijie SD-WAN solution has the capabilities of key business identification, intelligent business routing and video service optimization, which can realize the visual guarantee of key business according to different business characteristics, and support the stable operation of various high-speed services of education private network. Layered networks isolate services. An independent virtual network is created for each service on the same physical network. Virtual networks cannot access each other. All service networks are created and managed using SDN to reduce the complexity of management.
3S - Security: Firstly, identity is the first line of defense for security. Source-ID unified identity center implements unified identity management and universal unified authentication. Secondly, there are more and more types and numbers of terminals, which are basically unmaintainable. As a result, many users give up access security. Therefore, any unauthorized terminal can access the education private network, which brings great security risks. We are simplifying access security by deploying SMP+ Smart access systems across the network. The SMP+ automatically identifies terminals that access the Intranet, implements unified wired and wireless authentication on user terminals, and automatically or manually approves dumb terminals. Finally, the RG-BDS security big data platform is used to coordinate the whole network security equipment to locate and analyze the overall stage of the virus, realize the security intelligent situation awareness based on security big data, use the network + security linkage to actively block security threats, build a three-dimensional protection system, and help build a trusted and secure education private network.
3S - Simple Operation and Maintenance (Simple) : The education private network is not only an overall plan, but also has different management bodies, which requires hierarchical and decentralized management. How to efficiently complete the operation and maintenance of the backbone network and campus network is a big challenge. First of all, SD-WAN can realize extremely simple operation and maintenance of backbone network. SD-WAN controller can monitor and collect the running status of all equipment in backbone network, conduct comprehensive analysis, visual presentation, and quickly locate and report problems. Secondly, the use of Ruijie minimalist Ethernet all-optical network solution can realize the campus network extremely simple operation and maintenance, including campus network visualization, zero configuration for equipment, so that the school does not need to have professional technical foundation, can quickly complete the campus network problem location and fault recovery. Through RIIL operation and maintenance system, the entire education private network can carry out unified visual operation and maintenance on wired, wireless, security, virtual service network, business system and so on.
