VPN breaks through campus network access barrier realizes information sharing

The current campus network is generally facing the "three-way" problem, what is the "three-way" problem, how to solve these problems? Detailed spoke will be provided below.

"Tee" puzzle

I hope the Internet can connect the campus network

The development of network technology and computer technology has changed people's production and life style, and also changed the way of education and teaching, and made it gradually towards individuation, network and globalization. With the development of "school-school-pass" project, more and more primary and secondary schools have set up a campus network, in which the most direct relationship with teachers and students is the use of resource pool in teaching activities. With the enrichment and accumulation of these resources, many teachers seem to have developed a habit, even at home to prepare lessons also need to access to the school prepared by the rich and colorful resource pool. This is primarily the reason for Web indexing and search habits. So, this requires that the campus network must provide a convenient way of remote access.

Well-known remote access mainly refers to two types of access, one way is to use the remote access server, often refers to the DMZ area of services, the other is that remote clients directly access intranet resources, such as SMB access. And the latter's application needs more and more, which let us not start. There is a problem that we cannot open these dangerous ports because it will incur the patronage of hackers on the external network. (Usability and security are always a pair of friends)

The words of a school office worker are intriguing: "Every day I get rid of the normal work telephone, I can receive the call from the headmaster and other teachers." They often need me to open their computers, find out what they store in a set of folders, and send them via e-mail.

Eliminate management barriers, exchange of campus visits

Since December 2005, the layout adjustment of secondary vocational school has been spread out in all cities of our country. The educational resources of adult secondary School, Rtvu Extension School, vocational secondary school and Adult Vocational Education center should be integrated. In the situation of complementary advantages, network management has emerged a difficult problem.

The network integration of each branch and training place makes the information management cost of the school inevitable increase, but the extra cost increase is indeed uncontrollable. For example, school data storage, many schools are attracted by the concept of distributed storage, the attraction is that it has a lower investment costs and software deployment flexibility, to meet the special requirements of educational resources. However, when managing these distributed platforms, you will find that they are much more difficult and costly than originally thought.

As a result, many schools are now studying how to integrate these servers to regain the value of resources and management control. If more campuses exist, the control of web traffic to these sites has become a problem for geographically distributed schools. Administrators must try to handle the many tasks of installing, configuring, and managing network security for remote office networks, but in these remote offices there is a lack of network administrators and the maintenance of a dedicated line link is difficult and expensive.

Library Resources Integration and interoperability

After years of baptism of educational informationization, we have all set the goal of digital library is very clear: it is based on data storage and network services as the center, the construction of a distributed, large-scale and organized database and knowledge base system, to users or groups of users to provide instant information services, to achieve the collection of digital, A platform for delivering networking and service systems. For colleges and universities, the construction mode is the digitization of the campus's own collection, then it is to exchange the data with the foreign universities, and to pay royalties to the foreign commercial libraries, so as to obtain more browsing rights of the electronic documents. This is only related to the cooperation with foreign libraries, the application will also produce a corresponding binding. For example, in order to guarantee the intellectual property of the data information, the visitor must be the local net address of the copyright payment.

This problem is very prominent in colleges and universities, but in the near future, primary and secondary schools will encounter such problems. So it seems that the application of digital library must expand the access range. and the library cooperation outside the campus network will be the future trend and development direction. Therefore, in order to solve the network application and expand the access range of digital library, it is necessary to break down the application of the library and achieve the access on demand in the real sense.
