Fudan University, Shanghai technical assistance VPN Case

Application background In the education industry, the development of information technology, the use of dedicated networks, common dial-up Internet access as a campus based applications no longer meet the necessary means of remote access. VPN Technology Implementation, especially SSLVPN in the B / S, C / S structure of the network overall fit, as well as high-strength encryption to protect transmission security, performance, has gradually formed the mainstream of alternative models. On the other hand, campus Digital Library The application of scale. From the staff will start their own collections of digital books to and commercialization Cooperation Read the copyright to buy, and then share the data with the campus network so that students can easily check inside and outside of electronic literature. This is the Fudan University Education Information Students apply directly for one of the more extensive needs.



User needs Telecom, Netcom, education, three main lines of the access network, multi-line access will have data transfer between the lines when the delay phenomenon and three main transit route exchange is dispensable.



Yan, deputy director of Fudan University, China Information Office of Education in 2006, information security industry, Fudan University, the General Assembly information on the construction and application of a series of problems arising in the process were described. Specific performance: safety management measures are not perfect, inside and outside the network hacking attacks against the bad elements, Computer Vulnerabilities common, can easily access the internal LAN, internal users abuse network resources. Meanwhile, Yan is also the Information Officer Campus Safety Management characteristics are classified as follows: First, the campus speed of network speed, size large; 2, open campus network environment, users active; three colorful campus application information; 4, the number of information resources on campus are relatively concentrated; 5, the computer system management complexity diversity; 6, campus information the limited human and capital investment.



Implementation plan As shown above, the network center in Fudan Bingfeng S Series security appliances as the Access Gateway, as the school authorized to provide mobile users access services. Mobile users only through dial-up and the browser can and Fudan Network Center of VPN devices to connect to establish a virtual private channel.



Taking into account the large-scale application of Fudan access, Bingfeng S series, integrated load balancing module, you can stream a variety of scheduling algorithms for dynamic weight distribution, thus balancing Server Resource usage; the other hand, application testing and fault detection can be avoided due to service interruptions caused by line fault.



Other digital libraries, Bingfeng S series security appliances through the establishment of tunnel SSLVPN and outside the exclusive authorized mobile users to set up the tunnel, and extends the scope of services within the network, so mobile users can be authorized outside Visit Electronic Archive and query data.



The line access, taking into account the Fudan University main campus also has three lines, Bingfeng intelligent network streaming of multi-line played a unique and unparalleled in this advantage. Of all foreign network access and access to data within the network device through the corresponding local port to transit lines, not only network resources to ensure the exchange of visits at different speeds, the data will also be visits to the lowest packet loss rate.



Implementation of results


Network center in Fudan Bingfeng S Series Access Gateway security device as for the school authorized to provide access services to mobile users. Mobile users only through dial-up and the browser can and Fudan Network Center of VPN devices to connect to establish a virtual private channel.
