1 Introduction
1.1 Project background
Baoji Longxian Middle School is a standardized high school in Shaanxi Province. Due to the geographical environment, there is no systematic and relatively complete campus network system. In view of the requirements of the course design of this project, I decided to plan and build a high-performance, technologically advanced, and fully functional IT application system for my alma mater to build a complete digital campus environment. Specifically, it includes campus network system, campus broadcasting system, campus video surveillance system, computer network computer classroom, multimedia teaching system, etc. Although what I have done may not be comprehensive and perfect, these should be regarded as some insignificant repayments I have done to my alma mater!
1.2 The main content, characteristics and framework of the school campus network design
This time, the planning and design of the campus network information system of Baoji Long County Middle School is the main content. It needs to be explained that this is a very practical system, and it pays attention to practicality from the initial design architecture to product selection, so my design this time also focuses on reflecting the actual solution.
In the planning and design of this system, a typical network engineering system integration method is used for design, and the steps of demand analysis→logic design→physical design→implementation are adopted.
The content of this design is introduced in detail below:
In the first stage, a detailed demand analysis was carried out: starting from the school background overview, functional requirements, business requirements, network requirements, and environmental analysis, the network system of campus teachers and students, campus broadcasting system, video The monitoring system made a detailed description, listed the specific information points, and finally analyzed the security requirements and QOS requirements of the campus network.
The second stage is the logical design stage, which involves overall design and network system design. In the logical structure of the network, around the needs of the research, the design of the campus network system, the design of the overall topology, the design of network security and management, and the IP planning of the network are carried out from the aspects of topology and hierarchical design.
The third stage is physical design. Firstly, list the equipment needed in the whole scheme, combine the actual situation of the scheme with mainstream manufacturers, introduce and select network equipment, IP broadcasting equipment, and video surveillance equipment, and finally select the equipment that can meet the design requirements of the scheme and have higher Cost-effective mainstream products in today's market. In the design of the hardware structure, the integrated wiring is designed.
The fourth part summarizes the whole design scheme, the evaluation of this scheme and the prospect of this design scheme.
