摘要
随着计算机技术的成熟,网络已经成为人们生活中必不可少的一部分。在众多类型的网络中,广域网络是我们接触最频繁的网络之一。网络设备具有大型化、价格昂贵等特点,对个人而言,通过购买网络设备来架构真实网络环境是较为困难的。由此,网络仿真技术便应运而生。通过使用仿真软件,使用者能够构造网络结构进行模拟仿真、近而理解和优化网络的性能,加强对网络协议的掌握。网络仿真工具不仅可以为使用者节省开支,还能为使用者提供模拟网络环境仿真的能力。
是一款专业网络通信仿真软件。它可以用来搭建不同的网络模型,控制模型参数和提高网络性能等。的基本使用方法,然后在模拟一个公司在LAN和ISP之间的链接变化(单链路和双链路)进行对比研究,主要内容如下:
1、通过收集和阅读大量的参考文献,基本理论知识,仿真平台的应用。
2、的基本使用方法。
3、通过搭建一个公司的局域网,仿真平台上验证和分析了单链路和双链路的利用率和吞吐量,以及LAN和ISP之间的链接使用的相关性能对比。
4、在假定其中一个设备损坏的情况下,分析说明冗余链接设计的优缺点。
【关键词】网络仿真单链路双链路广域网
ABSTRACT
With puter technology maturing, network has e an indispensable part of people's life. In many types works, the wide-work is the most frequent one of we contacting. Network equipment have some characteristics like large, expensive and so on, for an individual, through purchasing work equipment to structure the work environment is difficult. Thus, work simulation technology e into being. By using the simulation software, users can construct work structure of simulation in order that we are able to understand and optimize work performance, and consolidate knowledge of work protocol. Network simulation tools can not only save money for users, but also offer the ability of work environment to users.
is a munication simulation software. It can be used to build work models, control model parameters and improve the performance of work, etc. In this paper, firstly, we simulate the information exchange in pany's four departments by , in order to explain the basics of using , and then we simulate of the change of the link (both single-link and dual-link) paring the LAN and the ISP in pany. Main contents are as follows:
(1) Through collecting and reading a lot of reference, It introduces the basic theoretical knowledge of , and expounds the application of simulation platform.
(2) simulate the information exchange in pany's four departments by
