[Abstract]:With the development of computer network technology, the application demand of campus network grows rapidly. With the increase of network nodes, the structure of campus network will become more complex, and the equipment performance and link bandwidth will be higher requirements. To build a complex campus network system based on multi-service, we need an effective means to plan, design and implement the campus network. The method of mathematical modeling is too complex, the method of planning and designing based on previous experience is not reliable, and can not meet the increasing demand of campus network. It is an inevitable choice to use network simulation software to model campus network and collect data by simulation. This paper describes the common network topology of campus network, the common network equipment, network transmission media, network technology and other operating principles and physical characteristics, on the basis of summarizing and analyzing the appeal content. Combined with the network topology structure of the unit campus network, the network structure of the unit campus network is modeled by the OPNET simulation software. On the basis of the modeling, the key parameters in the network are collected by simulating the common network behavior of the campus network. Analysis At the same time, according to the original network simulation model, by adding network nodes, changing the link bandwidth and other parameters that affect the network performance, the modeling and simulation analysis is carried out again. The influence of network performance parameters on the original network performance is obtained. Finally, by combining the improved campus network topology model, the feasibility of campus network upgrade scheme is obtained. This paper can provide an objective and reliable quantitative basis for the planning and design of campus network, improve the scientific nature of network design, shorten the period of network construction and reduce the risk of campus network investment, so it has certain engineering application value. Finally, this paper is summarized, and the future work is envisaged and prospected.
