Campus Network Design And Engineering Practice

Into the information age, various industries all departments after the Internet engineering, information construction increasingly common education field, especially as the center, CERNET education of national backbone scientific research units are an organic whole repeatedly, the realization of information resources sharing. But now in the middle of primary and middle schools, especially in underdeveloped regions, remote mountain ShangWangLv and informatization construction in primary and middle schools is sluggish and also in implementing "officer officer is connected" engineering background, based on the actual, meet the application, grasp informatization construction, serious thinking about how to change the traditional education model, to construct the information technology as the foundation of modern education is a very important and meaningful work, to promote the region education great-leap-forward development has the vital significance. Therefore, this paper tries to network service provider or system integrator of Angle to think how to these primary and secondary school campus network to provide a feasible design scheme.In this study, we with zhangjiajie of campus network construction of a middle school for empirical research object, and through comparison and analysis, proposed based on the layer 3 switching gigabit Ethernet as campus backbone, creating a "gigabit to exchange, BaiZhao to desktop" application-oriented function campus network, so as to satisfy solve less-developed regions primary and secondary school campus network application requirements.This paper first chapter firstly introduces the background, this article expatiates on the main work and relevant chapters content arrangement. The second chapter presents the design of digital network technology and knowledge. Analyzes and summarizes the characteristics of the technology and application of mainstream. The third chapter, a middle school in zhangjiajie of campus network design for the empirical study, from the school already some network actual, application condition and shortcomings drawbacks of carefully analyzed its demand (including basic demand, functional requirements and performance requirements), then formulated by the design principles and networking target, from the network planning, the network security mechanism, the network structure and realization in overall scheme design, realizes the whole network solutions to finalize the design. The fourth chapter are detailed design scheme and engineering practice. From the trunk network, equipment selection, integrated wiring design scheme is introduced in detail, and emphatically expounds the multimedia classroom network system, VLAN planning management, part. Then introduces the scheme of specific project implementation and construction management aspects of content. Chapter 5, gives the network testing program, and analysis are introduced the advantages and shortcomings of the scheme, and points out that the scheme can improve and perfect the direction. Through an empirical research and analysis, based on the layer 3 switching gigabit Ethernet backbone network scheme in the network advancement and practicability and economy can achieve a good balance between, is suitable for small and medium-sized school network actual and network application requirements. The scheme has in this region of a middle school campus network actual network practice and application indicates that the scheme design reasonable, using good can better satisfy the campus network, the application requirements, achieving the networking goals and objectives.
