Analysis And Design Of Building Campus Network And Its Security System In Colleges

Campus network has already become an important infrastructure for colleges to seek the development in this information age now. It is an important guarantee of a college education administration level enhancement to build an economical practical campus local area network with advanced technology and reliable movement under the new situation. The present paper focuses on the the promotion and transformation of the campus network of Jiujiang vocational technology institute.In this paper construction the campus network the key technology,Through analysis of the original campus network, according to the needs and principles of the campus network construction, application of network systems engineering thinking, on the campus network system works overall planning, closely around the basic network safe, smooth flow of exports and data network security, business services security and stability studies, analysis and design. Discussed in detail in terms of network engineering for upgrading the network technology selection (including the design and distribution layer backbone/access layer design), circuit design and equipment selection export, the original platform of the campus network infrastructure upgrade program proposed. Campus wireless network is an important complement to cable networks, this paper also proposed the design of the campus wireless network, expanding coverage of the campus network of information points for the future digital campus offers more advanced network infrastructure platforms. In addition, this campus network security and management is also carried out overall planning and system design.This essay has elaborated the network selection, the outgoing line design and equipment selection in detail in the promotion and transformation of the network (including the designs of backbone network, distribution layer and access layerd).This article has proposed the design proposal of the campus wireless net, an important supplement to the wired network and it has made the campus net information spread widely, which provides an advanced network platform for the digitized campus in the future. Meanwhile the essay has also made a general plan and a detailed design to the security and the management of the campus network.
