摘要
本文针对应用了CSMA/CD协议的总线型局域网进行仿真,研究数据包大小对网络性能的影响。首先介绍了OPNET[1]仿真平台,随后概括说明使用CSMA/CD协议的以太网的碰撞窗口的计算方法,由计算公式推导出发送的数据包越大、使用CSMA/CD协议的以太网性能越高的推论,并使用OPNET软件进行了仿真实验证明了推论。
In this paper we simulated a Bus Local Area Network which is based on CSMA / CD,and investigated how different sizes of packet affect network performance. We first introduced OPNET simulation software,then explained the calculation of collision window in CSMA / CD and got the deduction that larger packet will bring better network performance. Finally,we conducted a set of experiments using OPNET simulator to prove our deduction.
