The VPN network structure of Xiamen University utilizes the remote access function of Bingfeng VPN. That is, each user who needs to access intranet resources has a remote desktop account, that is, each student has an independent login account, and uses a VPN device to access the LAN to access various networks in the LAN of Xiamen University. Share resource. User analysis: In the development of informatization construction in the education industry, the use of dedicated line networks and ordinary dial-up access as the basis of campus interconnection applications has been far from meeting Xiamen University's demand for remote access. The realization of VPN technology, especially the comprehensive adaptation of SSL VPN on the network of B / S and C / S framework, and the performance of high-strength encryption to ensure transmission security, has gradually formed a mainstream alternative mode in colleges and universities. solution: The VPN network structure of Xiamen University utilizes the remote access function of Bingfeng VPN. That is, each user who needs to access intranet resources has a remote desktop account, that is, each student has an independent login account, and uses a VPN device to access the LAN to access various networks in the LAN of Xiamen University. Share resource. Such as FTP, remote desktop, or databases of various education networks. In addition, the Bingfeng SSL VPN security gateway establishes a private tunnel with the authorized mobile users outside the school by establishing a tunnel SSL VPN, which expands the service range of the intranet. Electronic database information. The Xiamen University Network Data Center has a cluster with no external IP address. There is a master node in the cluster, and then a Bingfeng SSL VPN security gateway is installed at the cluster's external network exit. The VPN device has established an external link with the cluster. After the VPN is dialed, the visitor is in the LAN of the cluster. In this way, the internal database can be accessed through the IP of the local area network. Since the FTP server is also the internal IP of the cluster, WEB links may be used later. For example, some WEB resources cannot be accessed through telecommunications and must be accessed through the campus network. Application effect: With its superior compatibility, Bingfeng SSL VPN security gateway exerts its ability to seamlessly integrate with the existing network architecture in this network structure. On the basis of not changing the existing network, all the applications of VPN devices are well played. Since the school itself already has public network lines for telecommunications networks and education networks, according to the current status of the network interconnection, on the premise of ensuring a large number of mobile user groups, multiple lines can coexist with each other to ensure that users access different lines Access speed. In terms of access methods, teachers and students outside the school use SSL VPN to log in to the school's VPN equipment, use account authentication, or the school's unified identity platform to directly log in to the school to achieve quick access to school resources and digital libraries.
