Network bottleneck highlights: Lufeng Middle School's information construction faces three major challenges

The information technology needs of Lufeng Middle School are mainly reflected in three aspects:

The demand for network bandwidth is urgent. The existing network equipment is no longer able to meet the needs of modern teaching. The daily teaching, teaching and research management and the life of teachers and students all need smooth Internet access, especially the application of classroom multimedia platform, monitoring system, broadcasting equipment, etc., which puts forward higher requirements for network bandwidth.

Insufficient multi business carrying capacity. Multiple services such as data, voice, and video need to be transmitted simultaneously without interfering with each other, which poses challenges to the network's load capacity and service quality assurance. As an important component of the campus network, the office network needs to ensure the priority transmission of administrative office and academic management systems. The lack of a unified network management platform leads to low efficiency in troubleshooting, making it difficult to achieve rapid response and early warning, and affecting the smooth progress of daily school management work.

There are shortcomings in wireless coverage and security authentication. The school needs to achieve wireless full coverage in classrooms, conference rooms, offices, dormitories, and other areas, supporting seamless roaming. At the same time, a secure and convenient authentication mechanism should be provided for different roles such as administrators, teachers, and visitors to ensure the compliance and security of network access.
