The intelligent lighting equipment distributed on the top of the corridor of the teaching building automatically adjusts the light brightness and switch status according to different time and scene requirements; the smart blackboards, school synchronized clocks, and student interactive devices installed in each classroom, empowered by the minimalist Ethernet all-optical network, provide teachers and students with rich teaching experience and learning support... Walking in Chongqing Guangyangwan Coral Middle School is like an encounter with a "campus" full of technology.

During the recent national demonstration meeting between Chongqing Guangyang Bay Coral Middle School and Ruijie Networks, reporters were invited to Guangyang Bay Coral Middle School and, led by Dong Bo, vice principal of Guangyang Bay, visited and experienced the "modern education" with a strong sense of technology . It is touching that in the field of education, which is in the stage of rapid digital deployment, Guangyang Bay Coral Middle School has not only become the "new business card" of Coral Middle School Education Group, but also the "vanguard" of Chongqing's smart campus construction.

In the wave of digitalization,

Chongqing Coral Middle School Education Group's new campus welcomes new demands

Guangyang Bay Coral Middle School, which belongs to Chongqing Coral Middle School Education Group, is a newly built campus of the group. When talking about the original intention of the construction, Principal Dong said: "In recent years, the group's business has continued to grow and develop, and the scale of education has ushered in a new round of expansion. The construction of Guangyang Bay Coral Middle School carries the needs of the group's development." However, with the continuous promotion of educational informatization 2.0 and "Internet + Education", as well as the requirements of the "Basic Guidelines for the Construction of Smart Campuses in Chongqing", the new campus has put forward new requirements for the construction and deployment of campus networks.

These requirements include that the campus network needs to solve the problem of multi-service carrying difficulties and alleviate the bandwidth pressure caused by the increase in classroom information points and IoT devices . As a group school, Chongqing Coral Middle School Education Group has multiple campuses, of which the old campus uses the traditional Ethernet architecture. However, with the rapid development of information technology and the sharp growth of informatization, especially in terms of bandwidth and scalability, the existing network architecture can no longer meet the growing business needs.

In the face of the difficulties encountered in the old campus, Guangyangwan Coral Middle School proposed high-standard campus network construction requirements at the beginning of planning and construction, and increased the scale and cost investment of network construction. The network architecture needs to support 10G data transmission rates to ensure high-speed and stable network performance. At the same time, the scalability and security of the future network must also be considered to meet the needs of the school's future development.

Principal Dong believes that the campus network is like a highway. Using the necessary solutions can "accelerate" the entire smart campus. In its contact with Ruijie Network, Guangyangwan Coral Middle School also gained an in-depth understanding of the characteristics of the Ethernet all-optical network, such as fewer fault points, high stability, large bandwidth, strong compatibility, and flexible expansion. Compared with the PON network, the minimalist Ethernet all-optical network has the advantages of "10G into the room, 1G to the desktop". Then Principal Dong revealed to the reporter, "After demonstration, our school decided to adopt the Ethernet all-optical network construction plan to carry out the network construction of Guangyangwan Coral Middle School."

10G switch in the classroom

Deployment of a simplified Ethernet all-optical network solution

Guangyang Bay Coral Middle School supports the network expansion needs in the next ten years

Guangyangwan Coral Middle School is equipped with a large number of networked devices and services, such as lighting equipment, cameras, smoke sensors on the top of the corridor, face recognition electronic class signs at the classroom door, smart blackboards and synchronized clocks in the classroom, as well as various business systems and cloud classrooms required for teaching . In fact, the lecture halls, canteens, parking lots, etc. on campus are also inseparable from the network, and these new scenes that have emerged in a blowout manner often require high-speed, high-bandwidth network support.

After adopting the simplified Ethernet all-optical network, the campus network meets the needs of Guangyang Bay Coral Middle School for large bandwidth, low latency, and high speed. In response to the needs of teaching services, the simplified Ethernet all-optical network relies on the advantage of non-splitting, deploys two 10G switches in each classroom, and brings Guangyang Bay Coral Middle School a high-performance network experience with 10G bandwidth 1:1 access to the room . Especially in the teaching scenario, the simplified Ethernet all-optical network will carry the high-bandwidth business needs of up to 60 classes in the future.

At the same time, in response to the increasing types and number of wireless network devices, the Aurora switches provided by Ruijie Networks are equipped with multi-rate 5G PoE electrical ports, which can give full play to the full performance of Wi-Fi 6 and meet the school's IoT device access requirements. With the advancement of educational informatization and the development of artificial intelligence and XR technologies, the demand for networked devices and business systems to access the network will gradually increase in the future. The simplified Ethernet all-optical can support the network expansion needs in the next ten years.

Cloud Classroom

Supporting smooth network expansion in the future is also reflected in the convenience of network deployment. Simply put, the minimalist optical access switch is deployed indoors, and service expansion does not require the use of optical fiber links, which truly achieves smooth upgrades and achieves the effect of one-time deployment and ten years of worry-free.

Achieve cost reduction and efficiency improvement

Minimalist Light helps Guangyang Bay Coral Middle School simplify operation and maintenance

In addition to supporting the network expansion needs in the next ten years, simplifying operation and maintenance is also the reason why Guangyang Bay Coral Middle School adopts a minimalist Ethernet all-optical network. Chongqing Guangyang Bay Coral Middle School has several teaching buildings, including A, B, C, D, and E. This also brings difficulties to the operation and maintenance of IT equipment in various classrooms in various teaching buildings. In the past, IT operation and maintenance personnel frequently traveled back and forth between various teaching buildings and classrooms to check fault information, which greatly increased the difficulty of operation and maintenance and reduced work efficiency.

After adopting the simplified Ethernet all-optical network, Guangyangwan Coral Middle School has realized intelligent operation and maintenance. This solution realizes full-link intelligent network operation and maintenance, optical link visualization, accurate fault location, equipped with high-order optical link diagnosis function, supports mobile phone scanning, and one-click acquisition of full-link details, so that one person can manage the entire network with one click.

In terms of operation and maintenance management, whether adding access switches or replacing faulty equipment, configuration is unnecessary, achieving extremely simple access and plug-and-play, and even completing device access and service launch in 1 minute. Especially when adding new services, operation and maintenance personnel can flexibly divide service subnets through visualized device ports, making it easy to isolate and share services.

This design also simplifies the operation and maintenance of Guangyang Bay Coral Middle School, which has multiple teaching buildings and a total of 60 classrooms, making it more time-saving and labor-saving. Principal Dong concluded that with the help of visual network operation and maintenance, the school's operation and maintenance efficiency has been improved, and the service failure recovery time has been shortened. The days when operation and maintenance personnel had to run around the floors to check for failures are now a thing of the past.

In addition, Chongqing Guangyangwan Shanhu Middle School configured the weak current room at the corner of the stairs at the beginning of its construction. The space here is relatively small, and it is difficult to install equipment. Using the minimalist Ethernet all-optical network construction solution, Guangyangwan Shanhu Middle School can achieve passive and maintenance-free weak current rooms in the building by using passive transparent convergence products. The school adopts the cabinet installation method to easily realize configuration and installation. This design not only solves the problem of small space and difficulty in obtaining electricity in the weak current room, but also realizes maintenance-free operation, greatly improving operation and maintenance efficiency.

Safety first

With the rapid advancement of information technology, digitalization and intelligence have become the key driving force for change in the education sector. However, this wave of change also brings with it a new challenge, network security. Principal Dong also summarized the security issues encountered by the school. He said: "The current network security issues in schools are mainly poor security equipment experience, difficult security policy configuration, a wide variety of terminals, and difficult operation and maintenance management."

How to solve this problem? Building a safe, reliable and efficient security system has become an urgent problem for Guangyang Bay Coral Middle School. This requires the security system to be able to uniformly monitor and manage resources within the campus network, while also improving troubleshooting efficiency and business risk prevention capabilities, and taking into account both initial investment and later maintenance. Not only that, at a time when data security is becoming increasingly severe, the campus network of Guangyang Bay Coral Middle School is built in full compliance with the requirements of Information Security Protection 2.0.

To this end, during the deployment process, Guangyang Bay Coral Middle School adopted security auditing, firewalls, gateways and other equipment provided by Ruijie Networks, and paid more attention to active defense, from passive defense to security and reliability, dynamic perception and comprehensive auditing of the entire process before, during and after the event, achieving full coverage of information systems, basic information networks, and Internet of Things level protection objects, to ensure security.

"Safety is no small matter." As a teaching name card of Nan'an District, Chongqing, Guangyang Bay Coral Middle School is at the forefront of digital education. Behind the construction of smart campuses represented by Guangyang Bay Coral Middle School is the support of ICT solution manufacturers represented by Ruijie Networks. And it is these excellent solutions that are helping to upgrade digital education and help various regions to create high-quality education.

Final Thoughts

Today, while the digitalization of education has greatly changed the way students learn and think, it has also brought unprecedented opportunities for the high-quality development of regional education. As the digitalization of education continues to advance, a network and a cloud platform will become a "tool" to achieve the goal of everyone learning, learning everywhere, and learning at any time, and to promote the balanced development of regional education.

On-site visit and communication

From the construction experience of Chongqing Guangyangwan Shanhu Middle School, we can feel that the wave of education digitalization has already surged. I believe that one day in the future, walking on any campus will be an encounter with a "campus" full of technology.
