The particularity of the online environment in the education industry presents unique challenges:

High concurrency reception and sudden traffic: Classrooms, lecture halls, libraries, dormitories and other areas are densely populated with teachers and students, with a large number of mobile terminals simultaneous connection of both ends leads to high network concurrency. The application of online teaching, high-definition video, VR/AR teaching, and other technologies has generated significant growth sudden traffic poses a severe challenge to network bandwidth and stability.

Business diversity and integration: Campus networks need to support multimedia teaching, scientific research and office work, safe campus video surveillance, and one cartoon, dormitory living, IoT and other various businesses. Different businesses have varying requirements for bandwidth, latency, and security levels. Different, it requires the network to have strong fusion carrying capacity.

Complex operation and high cost: The campus area is wide, the number of network devices is large and scattered, and the traditional network architecture complex, time-consuming and labor-intensive troubleshooting and maintenance, lack of professional IT operation and maintenance personnel, resulting in high operation and maintenance costs.

Security risks and data protection: Campus user groups are complex, highly open, and vulnerable to external network attacks and viruses Invasion. At the same time, sensitive information such as personal information of teachers and students, teaching and research data are at risk of leakage, and network security and data according to the immense pressure of protection.

To address the above challenges, this proposal proposes a set of core concepts centered on all-optical carrying, high-speed wireless, minimalist operation and maintenance, and internal security. The overall architecture of the smart campus network. This architecture aims to provide a flat, intelligent, and secure design for a smart campus provide stable, efficient, and secure online services.

Topology diagram of smart campus network:

As shown in the figure, the entire network architecture is mainly composed of the following parts:

Core DC: As the core hub of the campus network, deploying core switches, servers, and storage storage and security equipment, responsible for data exchange, business support, and security protection throughout the school.

All-optical campus network (POL): using wireless fiber optic network technology, extending fiber optic cables directly to teaching buildings, libraries, and dormitories internally, various buildings such as buildings are equipped with "fiber to table/room" technology, providing high bandwidth and low latency wired connections.

Wireless access layer: Deploy high-performance Wi-Fi 7 wireless access points (APs) in teaching areas, office areas, public areas, etc, provide seamless and high-speed wireless network coverage.

All Optical Campus (POL):

The POL architecture, with its flat, high bandwidth, easy deployment, and green energy-saving features, has become an ideal choice for the construction of smart campus networks choice. It deploys optical line terminals (OLTs) in the core computer room and connects them to various buildings' internal non source optical splitters through optical fibers. The splitter then distributes the optical signal to the optical network unit (ONU). ONU approaches the user terminal through a short distance cable connect devices such as computers, IP phones, printers, surveillance cameras, or connect Wi-Fi 7 APs to provide wireless services. This kind of the architecture greatly reduces the need for weak power rooms and aggregation switches in traditional Ethernet, simplifies the network structure, and reduces failures point.

4.1 Smart Classroom

Smart classroom is the core scenario of teaching innovation. This project deploys Wi-Fi 7 ultra fast wireless network to provide smart classrooms with ultra high bandwidth and ultra-low latency connectivity, fully supporting VR/AR immersive teaching, 4K high-definition interactive live classes, cloud desks innovative applications such as facial recognition. The Multi Link Operation (MLO) technology of Wi-Fi 7 ensures network stability in high concurrency scenarios with multiple terminals sex provides a smooth teaching experience for teachers and students.

Wi-Fi 7 Smart Classroom Intention:

4.2 Safe Campus

A safe campus is an important guarantee for campus safety. This project aims to build a high-definition video surveillance dedicated platform, utilizing POL architecture to support massive amounts of data high definition camera data ensures stable transmission and storage of video streams. At the same time, integrating AI intelligent recognition technology (such as facial recognition) implement real-time monitoring of campus perimeter, entrances, and public areas, as well as intelligent alarm linkage for abnormal events through behavior analysis move to enhance campus security and prevention capabilities.

Safe Campus Monitoring Network Intention:

4.3 Research/Office Area

The research and office areas have extremely high requirements for network stability and security. This case provides highly reliable wired connections through POL the architecture implements fiber to the table, ensuring the stability and bandwidth of scientific research data transmission. Meanwhile, through VLAN isolation technology the scientific research network is logically isolated from the office network and teaching network, and strict access control policies are implemented to ensure the integrity of scientific research data security and confidentiality.

4.4 Student Dormitory

Student dormitories are one of the most densely populated areas on campus. This case involves deploying high-density Wi-Fi 7 APs and POL connections provide high-speed and stable internet services. At the same time, implement refined traffic control and quasi authentication to ensure network fairness utilize and implement IoT applications in the dormitory area, such as smart water meters and smart locks, to enhance the convenience of student life.

Wi-Fi 7 Speed Experience: Provides several times the throughput of Wi Fi 6, supports Multi Link Operation (MLO), significantly reduces delay, meet the high requirements of future teaching and research for wireless networks.

All optical POL architecture: using fiber optic cables instead of traditional copper cables, greatly reducing the space and number of equipment in weak current rooms, and lowering costs low energy consumption, achieving green energy conservation, and possessing the ability to evolve towards the next 30 years.

Unified operation and maintenance management: Through an intelligent network management platform, centralized visual management of all wired and wireless devices is achieved management, configuration distribution, performance monitoring, and automatic fault diagnosis greatly improve operational efficiency and reduce operational costs.

Physical security protection: Build a multi-level and comprehensive security protection system, including exit defense walls and intrusion defense systems IPS, authentication, behavior auditing, ransomware protection, etc. ensure the security of campus networks and data.

The implementation of this plan will bring significant value to educational institutions:

Improving teaching quality and efficiency: High-speed and stable online support for immersive teaching and online collaboration, stimulating innovative activities among teachers and students power.

Ensuring campus safety and stability: The physical security protection system effectively resists cyber threats, and the monitoring of a safe campus ensures the safety of teachers and students personal and property safety.

Optimize resource allocation and management: Simplify network architecture, reduce operation and maintenance costs, and improve network management efficiency.

Promoting Educational Equity and Development: Providing High Quality Online Connection for Schools in Remote Areas, Narrowing the Digital Divide, and Promoting Education Balanced development in education.

Looking ahead to the future, with the continuous evolution of technologies such as 6G, AI, and the Internet of Things, campus networks will further move towards self intelligence and network development exhibition. The advanced network infrastructure constructed in this case will provide strong support for the school to meet these challenges and opportunities, assist the education industry in moving towards a more intelligent, open, and inclusive future.
