With the development of the national economy and the implementation of the strategy of rejuvenating the country through science and education, the campus network has become an infrastructure platform for all schools, and is regarded as one of the important indicators to measure the level of informatization and modernization of school education. Within the scope of the school, the establishment of a safe and efficient computer network that can provide resource sharing, information exchange and collaborative work for the school's teaching, scientific research and management is the fundamental purpose of establishing a campus network to serve teaching. **This paper analyzes the development of campus networks at home and abroad, introduces the functions and construction principles of campus networks, and aims at advancement, security and practicability.
The design and analysis of the scheme were carried out by taking the campus network of a middle school as an example. **This paper mainly expounds the advanced technologies such as three-layer switching and virtual LAN in the construction of the campus network, adopts VLAN (virtual network) technology for management, and analyzes the use of VPN (virtual private network) technology to realize the remote access of off-campus users to the internal resources of the campus network, so that teachers can access the internal resources of the campus network and deal with various affairs in a timely manner outside the school according to their needs. The modular design of the switching equipment in the design can reserve sufficient space for the expansion of the campus network.
In terms of security, the campus network egress filters the data flow through the setting of firewalls and routers, as well as the configuration of access control lists (ACLS), which is convenient for restricting the type of communication data in the network and restricting the users or devices of the network, so as to achieve the security isolation and protection of the internal and external networks. **Some factors affecting network performance are also briefly explained in combination with practical applications.

It is not difficult to analyze the truth of data. Yes.

1.Depending on the size of the school. Carry out scheme design, equipment selection, etc.
2.Then it is procurement, the things you need to buy socks are completely bought, don't do the project halfway but the materials are a waste of time.
3.Draw a logical physical topology diagram.
4.According to the topology, the field investigation is carried out to determine the direction of the line.
5.Then it's time for the wiring. In the process of wiring, the opposite sex will be labeled, otherwise there will be big problems when the equipment is put on the shelves in the future, for example, if you don't know that this wire is leading to **, then you have to test it one by one, which is a very cumbersome thing The label must be played.
5.Then there is the installation and commissioning of the equipment after it is put on the board. Cavity destruction is generally supported by the party providing the equipment.
6.Finally, there is the trial run, and after the trial run, it is the acceptance. Party A (referring to the customer) and Party B (the project operator) jointly carry out the acceptance.

The format of the graduation ** design proposal report in the planning and design of the LAN of the Internet café (general).
Since the proposal report is a general idea embodied in words, the length does not have to be too large, but the main issues such as the planned research topic, how to study, and theoretical application should be clearly explained, and it should contain two parts: general description and outline.
1 General. The general part of the proposal report should first put forward the topic and concisely explain the purpose of the topic, the current research status of the relevant topic, the application of the theory, the research method, the necessary data, etc.
2 Outline. The outline contained in the proposal report can be in thick lines, which is the basic framework of a research idea. It can be in the form of a whole sentence or a whole paragraph of Tongdong outline.
In the opening stage, the purpose of the outline is to make the basic framework clear to people, and there is no need to be as detailed as the table of contents.
3 References.
A bibliography of relevant references should be included in the proposal report.
4 Requirements. The proposal report should have a cover page, and the total number of pages should not be less than 4 pages. The layout format should comply with the following requirements.

3. The theoretical basis, research methods, and research content of Hu **.
Fourth, the research conditions and possible problems.
V. Expected Results.
Sixth, the schedule.
It's good enough, what else to change, just send it directly.
If you just want to connect two PCs equipped with Windows series operating systems, we can directly connect the two microcomputers through the serial and parallel ports of the computer, use the serial and parallel communication cables (PC to PC), and then select "IPX SPX Compatible Protocol" and "NetBeui Protocol" in Microsoft's "Dial-up Network Adapter" and "Protocol" in the "Adapters" under "Control Panel Network" in Windows. Then launch the "Control Panel", select "Add and Remove Programs", click "Install Windows Programs", select "Communication", click "Direct Cable Connection", and then use the Windows installation disk to install. Once installed, restart your computer. >>>More
It may not be limited by software, but it is done on the main route. Find a way to do port mapping.
It belongs to a local area network (LAN). A LAN is a type of private network, usually in or near a building, such as a home, office, or factory. Local area networks are widely used to connect personal computers and consumer electronic devices, enabling them to share resources and exchange information. >>>More
Campus network is not available.
There is no possibility. Rest assured, I also went to college. >>>More
