Design Of Small And Medium - Sized Campus Network

The campus network construction is an important part of each school, and its construction level reflects the overall level of school. In the process of realizing informatization campus, network construction is the basis, the resources construction is the core, the teaching application is the target, management system is the warranty. Campus network is an important part of education informatization construction, campus network change teaching methods and develop the knowledge of teachers and students, to a great extent, it improves the students’ ability of acquiring, analyzing and processing information, it is necessary to adapt to the modern society.Campus network has a variety of design for the school scale and the properties of the various, but design idea is the same:first, see the building layout of a school, analysis system construction requirements and constraints; and then, make sure the school Intranet service type, which can determine the school network facilities, the location of the site, management, the future expansion of the target content; third, according to the distribution characteristics of school buildings and demand giving corresponding network topology; fourth, determine the professional technology used in the design process, the choice of the equipment, wiring, software settings and other content and these contents must follow the standards and requirements; fifth net one one list for the implementation steps of the campus, and write down the possible problems and solutions, and post test.The test design the construction scheme of a campus network, expounds the general design of the campus network construction, especially set forth my own opinion on the campus network flow optimization, selection of network equipment, testing content,. The specific contents are as follows:the paper presents the long-term saturation problem of the campus export, deploy the QOS strategy in the exchange layer switches, because through the switch of all network traffic, QOS will mark, shaping, it not only ensure the normal access to critical applications, but also stops the non critical applications’s access, remove the effect of bursty traffic, illegal flow bring on the network,; Through the analysis and argumentation in the hardware, we choice the network equipment which are Huawei manufacturers, Huawei network equipment has better performance cheap. More importantly, it support Chinese version and more suitable for Chinese network; In this paper, using fiber optic cable in this complex system, Fiber optic cable can provide Gigabit bandwidth, provides room for future expansion. The access layer using100M category five twisted pair, to ensure the high speed data transmission.The construction of campus net is crunch time, building a more perfect and advanced campus network, it is significant and long-term.
