支持IPv4/v6的嵌入式网络实验设备的设计与实现

缺乏路由器、防火墙等的综合性实验装置是高校网络实验室普遍存在的问题。该文提出了在嵌入式L inux平台下研制通用、简约、低价的网络实验设备的解决方案,介绍了实验设备的硬件平台和软件设计,给出了系统引导加载程序、应用程序移植和设备配置等方面的实现方法。该实验设备支持IPv4/v6双协议栈,一机多用、扩展性强,可以进行多项网络技术实验,有效地提高网络实验教学质量。

The design and realization of embedded networking experimental equipment supporting IPv4/v6

The shortage of comprehensive network experimental equipment integrated router, firewall and so on, is a common problem for network laboratories in colleges. A solution about how to develop a networking experimental equipment with the characteristics of universal purposes, conciseness and cheapness, is put forward under embedded Linux system. In addition, introduction about hardware and software designing is done, as well as the realization technique in the aspect of boot loader, application migration and equipment configuration. With this experimental equipment that supports IPv4/v6, owning the property of multi- experiment as well as good functional extension, more than one experiment can be processed, and the quality of network experimental teaching can also be improved greatly.
