Research on the solution of EIP Campus Network system

[System Overview]

The campus network is a computer local area network which is based on the computer and serves the three major goals of teaching research, administration and internal and external communication. Through the collection, analysis and collation of a large amount of knowledge and information in the world, he is applied to school teaching by means of individual or comprehensive forms and techniques, such as visual, audio, text and multi-dimensional pictures. Thus, it has changed the passive teaching mode which mainly relies on the students ' abstract thinking in the past. The introduction of computer network into the primary and secondary schools, not only the large number of information storage, transfer to teachers and primary and secondary students, improve the teaching methods, improve the efficiency of teaching and teaching quality, and more mainly through the network, training teachers and students from the Internet to collect, analyze and deal with a large number of information Thus greatly improving the students ' learning quality to meet the needs of the information age in the 21st century.

[System Principle]

Campus Network Network system can be divided into Campus networks Center, teaching subnet, office subnet, library subnet, dormitory area subnet, logistics subnet and the original cable TV network transformation access network.

The construction of campus network should follow the three principles of practicality, expansibility and reliability of the system:

1. Practicality:

Education is an investment-oriented industry. Comparatively speaking, in the developing country, the economy is underdeveloped, which leads to the shortage of education funds and the single source. Therefore, the construction of campus network should fully consider the situation of specific schools, the construction of both economic and practical campus network.

2. Expansibility:

The continuous improvement of computer technology and the continuous expansion of its application will lead to its continuous upgrading and updating. Therefore, in the construction of the specific campus network, the Foundation and the main part of the construction and allocation should be forward-looking, to the terminal construction, should be left with the scope of expansion, so that the whole campus network construction can be developed continuity.

3, Reliability:

School is only the user of the campus network, it is not necessary and difficult to support network engineers. Therefore, in the concrete construction, should take into account the campus network of Ease of use, easy maintenance and reliability.

Because of this, high-performance, scalable, easy to upgrade, economic and practical "EVOC" industrial-grade computer, the construction of campus network system is the most competitive hardware platform.

[System Review]

1, the system uses the extremely high reliability "EVOC" industrial class computer, the use is simple, the maintenance is easy, while fully guarantees the system security, does not need the specialized network engineer to carry on the management;

2, optional backplane type, can be upgraded industrial motherboards, so that the entire system has a flexible expansion of the specific situation of different schools to change the system configuration slightly.
