Broad talent becomes virtue first, wisdom development first
Over the years, Shude Middle School has cultivated tens of thousands of outstanding talents for the country, on the one hand, it is inseparable from the school's adherence to the development concept of "Shude Cultivating People, Broad Talents, Outstanding Talents, and Holistic Education", on the other hand, it also benefits from the fact that the school has always kept up with the development pace of the digital intelligence era, adhered to the school-running concept of "technology empowers education", promoted the development of school informatization and intelligence, and consolidated the digital intelligence foundation of the smart campus. In view of the fact that the school's existing network has been in operation for many years and cannot meet the current situation of wired and wireless service carrying in the later stage, Shude Middle School urgently needs to promote the construction of a smart campus by building a high-quality, reliable, and intelligent high-quality and intelligent connection network base. On the whole, the network construction requirements of schools are as follows:
1
Build a high-quality campus network:
Previously, with the passage of time of network construction, there were challenges such as aging lines and easy loops in the wiring of twisted pair cables in schools. In the process of network upgrade, the school urgently needs to re-optimize the deployment of network cables, and at the same time, it is also necessary to achieve full network coverage for different campus scenarios such as small office areas and large teaching areas, and meet the information security needs of Shude Middle School for business sustainability and important data in the next five to ten years.

Promote intelligent network O&M:
In order to ensure the smooth development of teaching work, the network construction of Shude Middle School should be managed and monitored in a unified manner during the operation and maintenance stage, and fault detection should be quickly located. To this end, the school needs to build a unified network management system to reduce the workload of equipment management and operation and maintenance, so that teachers and operation and maintenance personnel can devote more energy to daily teaching and management. At the same time, the school also needs to build a trustworthy campus network to efficiently ensure the online security of all users on campus.
Based on this, Shude Middle School has chosen to work with Huawei to build a high-quality, reliable, and intelligent network base for high-quality and intelligent connections through Huawei's high-quality 10 Gigabit campus network solution.
1. High-quality 10 Gigabit Ethernet all-optical "foundation" to achieve the "ultimate experience" of campus networks
By deploying Huawei's high-quality 10 Gigabit Ethernet all-optical campus network solution, we built an integrated wired and wireless network system to efficiently improve the network performance of Shude Middle School. Among them, the high-quality 10 Gigabit Ethernet all-optical network is plugged into the room through optical fibers, and the new remote modules are plug-and-play, helping Shude Middle School complete a smooth network upgrade and meet the needs of the school's campus network construction in the next ten years.
It realizes extremely fast access and upgrades on the basis of gigabit optical ports, ensuring that each classroom can reach 4 GE uplink and 8 Gigabit downlink, and supports all kinds of high-definition video conferencing without lag, meeting various intelligent applications in smart classrooms. Create a high-quality campus network for interactive teaching and mobile office anytime, anywhere. For some scenarios on campus that have extremely high requirements for business continuity, such as examination rooms, campus security monitoring, and broadcasting systems, it also supports photoelectric hybrid cable access to achieve uninterrupted power outage.
To achieve the ultimate experience, a fanless design is adopted in the construction of remote modules to achieve no noise throughout the whole process, and the power consumption of a single port is less than 1W, so that students no longer need to be disturbed by equipment noise when reading and learning in the classroom. At the same time, the remote module also supports energy-saving technologies such as port sleep and automatic port power adjustment, which saves more than 30% energy compared with the industry. Such a design can not only provide a comfortable teaching environment, but also reduce the school's electricity bill.
The remote module can be selected from 4, 8, or 16 ports according to the number of terminals, and the remote module is designed to be small and can be directly installed in the information box in the classroom or under the lectern. Through the original "asteroid" architecture, the traditional three-layer network architecture is simplified to a "core-access" two-layer architecture to realize fiber-to-the-classroom. The remote module is plug-and-play, free of planning and configuration, and can be brought online immediately after power-on, which can reduce the management node by 80%. In addition, by directly managing and configuring on the core switch, it not only reduces the setting of the weak current room in the building, but also saves 77% of the wiring.
2. Full coverage of wireless network, enjoy mobile teaching anytime and anywhere
Based on Wi-Fi 6 technology, Shude Middle School has partnered with Huawei to achieve full coverage of campus wireless networks. From classrooms, meeting rooms, auditoriums, gymnasiums and other outdoor areas and public spaces, Shude teachers and students can enjoy 100M bandwidth network in any area of the campus. At the same time, the solution can also ensure the efficient development of digital teaching in the smart classroom, and meet the business requirements of 50 students in a single classroom at the same time to send on-demand videos and carry out teaching activities. The user bandwidth is not limited, bringing teachers and students a high-speed Internet experience.
In addition, to ensure the network experience of critical services and audio and video services, Huawei's high-quality 10 Gigabit campus network solution can also allocate bandwidth on demand, and group VIP users such as school leaders separately to prioritize bandwidth requirements, reduce network latency, and build a high-quality 10 Gigabit campus network environment with zero roaming, zero lag, and zero disconnections.
3. Build intelligent O&M to help simplify campus network management
Based on the principle of reducing costs and increasing efficiency, Huawei helped Shude Middle School simplify network deployment, plug and play all devices, and achieve fully automated rollout.
In addition, with the help of Huawei's iMaster NCE-Campuslsight platform, schools can accurately identify user network problems based on user network quality assessment and backtracking. Through network-wide network health quality assessment, the overall network quality is systematically controlled and network security is guarded.
With the rapid development of artificial intelligence and digital intelligence technologies, networks need to carry more intelligent application services and provide better network services and experience in the future. At present, the construction of campus network should not only meet the existing demands of teaching services, but also face the future, continuously ensure the innovation and innovation of teaching methods, and carry the evolution needs of the next five to ten years. Adhering to this principle of network construction, Shude Middle School has worked with Huawei to build a high-quality 10 Gigabit campus network and build a high-quality and intelligent connection base for smart campuses. In the future, Huawei will continue to provide high-quality, reliable, and intelligent connectivity for the digital transformation of the education industry in Sichuan Province through its leading technologies and solutions, helping more schools build smart campuses, achieve the development goals of education and teaching, and embark on a new journey of high-quality development.
