To now, SSLVPN applications in the education sector can be summarized into three integrated demand, thus creating a three trends. SSLVPN information technology in the development of education, has been widely recognized by many colleges and universities. SSL itself is set to provide authentication, confidentiality and data integrity encryption technology, which uses a symmetric encryption technology commonly used in Web browsers and Web servers to establish a secure communication channel between. Such as online banking application is based on SSL set up. For SSLVPN applications in the education sector can be attributed to the comprehensive needs of the following three trends: the large-scale application requirements under the VPN access, mobile access to digital library, campus network of multi-intelligent diversion. VPN access under large-scale application To the introduction of VPN access, you must take into account the large-scale applications to support problem, we must ensure that external network access to campus network needs, and the application of large-scale access under the security from the client, from the the stability of the server, from the transmission line and server data processing efficiency, as well as from the ease of user applications. Four were indispensable. Comprehensive classification, reflecting the most prominent issues are as follows: large-scale applications, causing server overload operation; single point of failure, resulting in increased business risk; and high-technology equipment, making the procurement costs. By the above analysis of the problem of access for multiple users to tunnel ICEFLOWSSLVPN safety equipment, for example, as the center of the campus network gateway to allow users to establish special security through the SSL tunnel mode, then Web Browser remote login. So the user can solve the much-needed security access, and ease the line occupied by the high cost. Under large-scale application of VPN access solutions, the integration of technology can fully play its role. Through hardware integration, firewall, load balancing and other large-scale applications, as well as other applications of the technology involved in the VPN devices, integrated them altogether, so the idea of a machine can be fully realized, not only to enhance the performance of application equipment maximized, is also true for the users to reduce the equipment diversified funds. Analyzed and compared using SSLVPN equipment, the first thing on the equipment cost savings of load balancing equipment expenses. The integrated load balancing module in the event of a large flow of data position, according to the scheduling algorithm and dynamic weight distribution calculation, the data streaming to the standby server to main server overload relief operation, while improving resource utilization to eliminate redundant Yu. Second, work in an integrated strategy for the VPN load balancing device to add the application testing and load testing capabilities, you can also protect the single point of failure occurs, other equipment failures to timely response and access equipment, the work of the data stream. Mobile access to digital library As the face of campus digital library user groups first, our students and teachers that lay outside the mobile authorized users, so in preparation, the high cost of consumption and undesirable. Digital Library of the current school building program, the Fudan University gives us a good reference case, as shown. Chart Fudan University Digital Library Way to build a first collection of its own digital campus, and then the co-operation with foreign universities to exchange library, and to pay royalties for foreign commercial library, for more information, visit the power of electronic documents. Is involved here and overseas libraries, applications also have a corresponding binding. In order to ensure data information such as intellectual property, visitors must be paid royalties within the school network address. This view, the Digital Library to expand the scope of access. Cooperation with foreign libraries is limited access to external network can only guarantee that the application of internal IP addresses, it is apparent contradictions. Therefore, to solve the network application, expand the scope of digital library access, the application must be limited to break the library, in the true sense, to demand access. Can be seen from the Figure, VPN security equipment plays a key role. Any authorized user outside the network, through SSLVPN access technologies, remote access VPN devices, access to campus network, completion of the establishment of VPN tunnels; followed by the source IP address of VPN equipment change, the introduction of IP address outside the network of mobile technology will replace automatically authorize users, and guide each other access digital library catalog. Here, mobile users outside the network can be selected with the cooperation of foreign holdings of free access, without further manual input validation. Intelligent multi-line streaming From the external network access demand, security lines parallel, optimal routing, real-time routing is the primary requirement under the current application. Access from within the network relative to demand, optimizing transfer, data streaming is also indispensable. Intranet users to access resources outside the network, VPN equipment will be based on the user's destination address, access the appropriate resources to guide the other line. This is a multi-line embodiment of intelligent streaming technology; when the external network when users access the intranet, VPN equipment will access the user's source address, and guide each other access to the appropriate line port, purpose of visit, resources, embodied here is that adaptive intelligent routing. Diverse network routes, resulting in data complexity, if not multi-line intelligent streaming technology, it is possible to access the public network resources, it is out of line by the Education Network. Lines too long and there will be differences in bandwidth problems mentioned before. But essentially, using intelligent streaming applications, the campus network to access resources outside the network can access the port by the corresponding line out, get access to address, in order to optimize transmission of data streaming. Multi-line applications for the network status, the most prominent expression of different lines to the interconnection between operators on. Under normal circumstances, exchange of visits between the different line operators, have to transit through a specific gateway, latency about 420 ms or more, but make integrated circuits for smart technology transfer VPN devices, you can reduce the delay 60 milliseconds less, which is basically the normal duration of the transmission line, which is to ensure the coexistence of multi-core. The future, in applications in the development of space reserved for the corresponding decision of the sustainability of development of the university, will achieve technical modular integrated into devices, then no longer a proprietary software vendors such as Huawei 3Com , Bingfeng network VPN vendors support the modular, on the other hand high-end customers reduce the equipment, diversified The e-commerce company in China offers quality products such as China LED Ball Bulbs , China Others, and more.
