2. Click "Next" and select "No, create a new connection" (if the connection has not been created, please go directly to the next step).
3. Select "Use My Internet Connection (VPN)" and fill in the connection address given to you by the school in "Internet Address". The address of each school is different. This is the IP of the school server. Fill in and click Next.
Fill in your account and password, remember the password, and then enter it when you log in later. (Don't forget)
5. When finished, return to the desktop, click Network, right-click VPN, and select Properties. The window options that appear are all network security, and none of them can be less. Both must be set as the choices in the diagram, and they must be the same as those in the diagram.

1, high-speed local area network connection-the core of campus network is the network of teachers and students on campus, so campus local area network is the focus of system construction, and network information contains a lot of multimedia information, so high-capacity and high-speed data transmission is a basic requirement of the network;
2. Diversification of information structure-campus network applications are divided into three parts: electronic teaching (multimedia classrooms, electronic libraries, etc.). ), office management and remote communication (remote teaching, Internet access, FTP service, online games, etc. ). The data type is complex, and different types of data have different requirements for the quality of network transmission;
3. Safe and reliable-there are a lot of important data about teaching and file management in the campus network, which will bring great losses whether it is damaged, lost or stolen;
4. Easy to operate and manage-the campus network has a large area and complicated access, and the network maintenance must be convenient and fast, and the equipment network management function is strong, which is convenient for network troubleshooting.
5. Authentication and billing —— Schools must effectively control students' access to the Internet and adopt billing strategies to ensure the utilization rate of the network.
Campus network system is divided into core layer, convergence layer layer and access layer from the structural level; Functionally, it can be basically divided into campus network center, teaching subnet, office subnet, dormitory subnet, library subnet and so on. According to the number of campus network users and network application, it can be divided into three types: large campus network, medium campus network and small campus network. Based on the above characteristics of campus network, we must fully consider the advanced nature, standardization and openness, reliability and availability, flexibility and compatibility, practicality and economy, security and confidentiality, expansibility and flexibility of the network when designing campus network, and make full use of limited investment to build a comprehensive network with high cost performance.
With the development of economy and the implementation of the national strategy of rejuvenating the country through science and education, the construction of campus network has gradually become a basic construction project of a school and an important symbol to measure the informationization and modernization of a school's education. At present, most qualified schools have completed the hardware construction of campus network. Then, for many years, the understanding of campus network is not comprehensive enough, and there are even great misunderstandings. For example, the higher the network construction, the better, the blind pursuit of high investment in construction, the lack of comprehensive planning, development and application of campus network construction; It is considered that the completion of campus network and access to the Internet are equivalent to the automation and informatization of teaching and office, but there is a lack of comprehensive management of campus network, application training of technicians and teachers, and development and accumulation of teaching resources. All these have greatly hindered the practical benefits that campus network should play in school management, education and teaching.
In recent years, distance education in China has developed rapidly. Statistics show that the Ministry of Education has approved 67 colleges and universities to carry out the pilot work of modern distance education, opened more than 40 majors covering 10 disciplines such as engineering, management, medicine, literature, science, agriculture, economics, teaching, law and philosophy, and set up nearly 2,000 off-campus learning centers (points) of modern distance education, with a total of 6 registered online education students. In addition, nearly 70% of colleges and universities in China have established campus networks, which are used to develop online teaching, digital libraries, online courses and teaching resources.
