随着网络带宽的越来越大以及嵌入式技术和嵌入式设备的日益发展成熟，过去的很 多设备如今变成了可管理的网络设备，它们不仅嵌入了操作系统和拥有自己的IP 地址，而 且还通过嵌入web 形式的网络代理端以方便用户的控制和管理。本文通过在arm920t 的开发 板上移植BOA（一个开源的web server），并嵌入到接入网络设备当中以实现对其进行web 化的控制和管理。(With increasing network bandwidth and embedded technology and the increasing development of sophisticated embedded devices, over the past many devices now become manageable network equipment, which not only embedded operating system and has its own IP address, and through web forms embedded in the network proxy client to facilitate the user' s control and management. In this paper, the development board in arm920t transplant BOA (an open source web server), and embedded in the access network equipment for them to achieve their web based control and management.)
