Dual-Core Network Construction Solution for a Key High School in a County of Henan Province

With the rapid development of information technology, educational informatization has become an important means to improve the teaching quality and management level of schools. For key high schools, building a dual-core network is not only a technical demand of informatization construction but also a strategic measure to improve the quality of education and promote the development of the school.

Customer Background

A key high school in a county of Henan Province is a school under the nine-year compulsory education system, with about two thousand students and approximately 200 teachers. The school has around 100 classrooms, with an average of 40 students per classroom. In order to ensure the efficient execution of teaching tasks and diversify students' learning methods, the school wants to improve the outdated network infrastructure that cannot keep up with the pace of the times through network construction.

Importance of Dual-Core Network Construction

• Improving Teaching Quality: The construction of a dual-core network helps teachers to use the network for a variety of teaching activities, such as live courses, online discussions, and resource sharing, greatly improving teaching effectiveness and students' interest in learning.
• Enhancing Management Efficiency: The dual-core network optimizes the school's management processes through information technology, improving management efficiency. For example, student attendance, grades, and other information can be updated and queried in real time through the network.
• Ensuring Network Security: The redundancy design in the dual-core network improves the reliability and security of the network, preventing the impact of a single point of failure on the entire network. Key high schools usually have a large amount of student and teacher data, and the security design of the dual-core network can effectively protect these sensitive information to prevent data leakage and network attacks.
• Supporting Innovative Teaching Models: The dual-core network provides technical support for innovative teaching models such as flipped classrooms, personalized teaching, and blended learning. These teaching models require strong network support, and the high bandwidth and low latency characteristics of the dual-core network can meet the needs of these emerging teaching models, promoting innovation and development in education and teaching.

Challenges Faced

• High Technical Complexity: The design and implementation of the dual-core network involve complex technologies, including network topology design, equipment configuration, and network security policies. The school can cooperate with professional network service companies to introduce external professional technical forces to better cope with the challenges brought by technical complexity.
• High Network Security Risks: In the construction of the dual-core network, attention should be paid to maintaining the school's network security. Key high schools usually store a large amount of teacher and student information and teaching resources. Once a network attack or data leakage occurs, it will have a significant impact on the school. It is recommended that the school improve the network security protection system to ensure the security of the school network during the upgrade process.
• Device Compatibility Issues: In the process of dual-core network construction, there may be compatibility issues between old and new equipment. When selecting equipment, we should invite a professional team to assist and fully consider the compatibility and scalability of the equipment, choosing equipment with good compatibility to ensure that the network construction is carried out smoothly and put into use.

Solution

This project builds a high-performance and highly reliable network solution for the school through multiple network devices from the core layer to the access layer. The core layer is responsible for high-performance traffic forwarding and routing selection, the distribution layer provides a variety of wide area network connection options, supporting the distributed network deployment of the enterprise; the access layer provides high-density access ports, supporting the connection of various access devices, ensuring efficient data transmission.
