摘要
在网络规划设计过程中，对于不同需求而设计的一个网络，经常会用到不同的拓扑结构，出现多个不同的设计方案。但是由于工程造价问题，无法对不同的方案进行实际验证选择。网络仿真是一种利用数学建模和统计分析的方法模拟网络行为,从而获取特定的网络特性参数的技术。网络仿真以其独有的方法为网络规划设计提供客观、可靠的定量依据,从而缩短网络建设周期,提高网络建设中决策的科学性,降低网络建设的投资风险。通过为一家电子元件制造厂设计了几种网络实现方案，并利用仿真软件OPNET对这几种方案进行模拟，得到了不同的模拟结果参数。实现了方案的最优选择。

Title          Network Planning and Design Based on OPNET      
Abstract
In the network planning and design process, using different topology to design a network for different needs, often results a number of different design options. However, due to construction cost issues, it’s impossible to verify the actual choices for different options. Network simulation is a technology that simulates network actions through mathematics modeling and statistical analyzing, consequently achieves the specific network performance parameters, objectively provides the reliable basis for the network planning design, reduces the network construction cycle, makes the policy more scientific in the network construction, and reduces the investment risk of network construction. Through the design of several network options for an electronic components factory and the simulation for these several programmes with the simulation software OPNET, we have obtained the different parameters of the simulation results .Its aim is to achieve the optimal choice of the programme.
