基于思科模拟器中不同VLan之间发送电子邮件实验的设计与实现

摘要

VLan是交换机中一种常用的技术，其具有提高网络安全性、减少广播风暴等特点。文章通过介绍VLan的方法理论以及特点，在思科模拟器Cisco PT 7.0上给出了VLan的典型的划分方法，最终在不同的VLan之间，实现相互发送电子邮件的效果。通过实验仿真，人们发现VLan能够为今后的网络拓扑架构研究奠定理论基础。%VLan is a common technology in the switch, which has the characteristics of improving network security and reducing broadcast storm. By introducing the theory and characteristics of the VLan method, this paper gives a typical division method of VLan in the Cisco Packet Tracer 7, and ifnally in different VLan, achieves the effect of sending e-mail to each other. Through simulation and experiment, we found that VLan can lay the theoretical foundation for the future network topology structure research.
