嵌入式网络终端路由功能的实现方法

Implementation of routing function in embedded network terminal

嵌入式网络终端中高效的路由功能实现方法针对ADSL接入方式,向内部网络的另外一台终端提供公网IP地址等网络参数,避免了网络地址转换、分组校验和的重新计算等复杂操作,资源占用少,适合在资源有限的嵌入式网络终端中实现。

This paper described a method of implementation of effective routing function in embedded network terminal. Under ADSL network connection, this method could provide public IP address and other network parameters for one terminal in the internal network, and avoided some complicated operations therefore, such as network address translation, recalculation of checksum of packets, etc. This method employs less resource, and is suitable for the embedded network terminals with limited resource.
