States Education Department, the "national education development" Eleventh Five-Year "Plan" clearly states that the network speed up the teaching and research, education, government Information And efficient construction of digital library applications, the various colleges and universities to further enhance the level of information technology.
Many colleges under the policy guidelines for the domestic information technology have accelerated the pace of the school library as the concentration of educational resources, it is walking in front of the other departments. The university libraries have established their own Digital Library, in order to enrich the library of digital content, books, colleges and universities in recent years through the introduction of a number of ways Electronic Resources for school teachers and students offers a wealth of professional teaching and research information to facilitate the conduct of teaching and research work carried out. However, publishers of electronic resources, limited only by the majority of electronic resources is usually authorized after the school in the network IP address Visit , Teachers, professors can not go home after a visit to these electronic resources, students summer vacation at home is difficult to access to these electronic resources, some schools Cooperation Closely related to education and scientific research institutes, the company also made the request to access electronic resources. More and more demands have emerged out of school visits, library information technology department needed a remote access mode, so that teachers and students and can not use third-party partners Campus Network Can access the school library as when the intranet, electronic resource sharing to achieve the maximum, increase the utilization of electronic resources.
Traditional Solutions About insufficient and SSLVPN solutions
Now on the market for remote access to the following three ways: 1, port mapping; 2, traditional IPsecVPN; 3, reverse proxy software; for library resource sharing for the purpose of all or more than traditional There are some deficiencies or less:
1, port mapping: This is the earliest so that users within the network, access to resources in the most direct and simple way, but as the technology develops, the way that remote access is also gradually reveals its limitations and shortcomings, especially in terms of safety, too much port mapping will cause great library network security risks, and the library's electronic resources is extremely rich in this case, the port mapping configuration work is also very tedious, lack of maneuverability;
2, the traditional IPsecVPN: IPsecVPN network as a mature form of the network connectivity in remote access performance is not satisfactory in this regard, although the guarantee after the remote access network built up within the network security level not reduced, but the access necessary to install client-side software features have been used to condemn significant numbers of users of such solutions, headache, client configuration and the attendant complicated compatibility issues have plagued a large number of customer follow-up maintenance work to the network maintenance sector increased to a greater degree of difficulty of work;
3, reverse proxy software: reverse proxy software as a low-cost way to get remote access to some success, but its effectiveness depends largely on access to install software on server performance problems that restrict this ways to further promotion, but the server itself has also led to the instability of the reverse proxy software in use when the event of a large concurrent access to visit often slow, and even can not access the situation, many libraries in the early deployment of units reverse proxy software for IT investment had to build a new remote access network;
Deeply convinced of the advantages of solutions and value note note
Deeply convinced of the technology products based on its SSLVPN provide remote access network, a good solution to the deficiencies of the traditional solutions for the University Library provides a fast, safe, easy to use remote access methods.
1, deeply convinced of the SSLVPN particularly suitable for a large number of external users access the network, with easy to use (just need to rely on the browser, does not require a separate install any plug-ins), do not rely on the network environment (as long as access to the Internet can access), small amount of work to maintain (not to install the client, terminal access to the Internet can be used) features, after the deployment of external users do not need to install any client software, directly using the browser login, strict authentication can enter the library after within the network, access to the appropriate resources to match the entire network management for network management and maintenance workload is deployed deep within the library network convince M5X00-S a hardware device.
2, only the campus network for access to IP to the normal situation, convinced IPTunnel through deep pools of virtual IP technology, IP section of the campus network assigned to the virtual IP pool, each personnel can access the virtual IP access. Radius and LDAP can also be read in the allocation of the virtual IP, so that each user can get access to come in within the appropriate network IP, barrier-free access to electronic resources.
3, excessive issues of single IP flow, deep convincing virtual IP pool technology, using polling method, to avoid excessive single IP flow was blocked, effectively avoid some of the downloaded Electronic Resources Association blocked off traffic large IP problems.
