的校园网建模与仿真
摘要
近年来,随着计算机科学技术的发展,特别是网络技术的发展,高校规模的扩大和人数的增多,对网络的需求越来越大,对上网速度的要求越来越高,对业务的需求迅速增长,如语音、图像、视频等多媒体数字业务。需入网的结点迅速增加,因此网络的结构更复杂,对设备性能的要求更高,链路速度更快。建设一个基于多业务、复杂的校园网络系统,其投资规模是非常庞大的,需要一种有效的手段对校园网进行规划、设计、并实现。通过数学建模的方法过于复杂,根据经验进行规划设计的方法不可靠,不适应日益增长的网络需求,利用网络仿真软件来对网络模型进行建模并仿真便成了必然的选择。
本文的主要研究任务,仿真软件,对我国一般大学校园网的网络结构进行建模,模拟网络行为,对关键参数进行收集,分析,并在原有模型上添加网络结点及应用,再进行仿真,分析,对比,得出改进设计方案是可行性。
本文的研究对校园网的规划、设计、网络建模都具有一定的指导意义,可以提高网络设计的科学性,缩短网络设计周期,降低校园网网络的投资风险。最后,对本文进行了总结,同时对未来的工作进行设想和展望。

Abstract
In recent years, puter science and technology development, especially the development work technology, colleges and universities to expand the size and number increases, work's growing demand for increasingly demanding high-speed access for business needs rapid growth, such as voice, images, video and other multimedia data services。 Network nodes need to rapidly increase, so work structure is plex and more demanding on the equipment performance, link speed, the building of a multi-service-based, complex work system, its scale of investment is very large, need for an effective means of pairs of work planning, design, and implementation。 Through mathematical modeling approach is plicated, through experience, the planning and designing method is not reliable and not suited to the work needs, work simulation software to model work model and simulation has e an inevitable choice。
The main task of this research is through simulation software, for China's general work, work structure for modeling, simulation work behavior, the key parameters of the collection, analysis, and add in the original model of work nodes and applications, and then simulation, analysis, comparison, come to this design is feasible。
This study on the work planning, design, network modeling has certain guiding significance work design can improve the scientific nature of work places a short design cycle, reduce the investment risks of work。 Finally, this paper summarized the same time, the wo
