Design And Implementation Of Campus Network Of VPN

In the information age, to build digital campus be imperative, and the existingspecial access network has been unable to meet the development needs. Colleges anduniversities need through the establishment of VPN network in line with their ownneeds, change data transmission mode between different geographical locations,improve the level of information and the efficiency of the school. The VPNtechnology theory and realization method, proposed a targeted at campus networkVPN solutions.This paper first describes the basic concepts of VPN, describes the basicfunctions of VPN, introduced the VPN classification and VPN tunnel technology.Then the paper makes a detailed analysis on the current situation of AProfessional Technology College campus network, discusses the application of thecampus VPN network, is proposed for the VPN characteristics of Career TechnicalCollege, presented the system construction goal and the overall topology of VPNnetwork.Then the thesis described the detailed design process of the campus VPNnetwork, the design of campus network VPN scheme, the security of campus networkis designed, the design of the SSL VPN authentication mechanism, discussed theclient authentication, the server authentication, the authentication process, a one-timepassword authentication method based on digital certificate is presented, describingthe process of creating a digital certificate.Finally, the paper introduces the implement method of campus network VPN,VPN and Access are connected to realize the implement method of VPN, a detaileddescription of the SSL VPN authentication mechanism. The VPN system login, therelated function of VPN, VPN performance and security of the data access are tested,verified the effectiveness of VPN system.System development and testing work has been completed, at the A ProfessionalTechnology College, running for a period of time, which has achieved good results,has a good reference value and guiding significance to the construction of the systemon the practice of campus network of VPN.
