| 摘 要： | 该文研究了应用于嵌入式系统中的一种轻量级TCP/IP协议栈—LwIP( Light-weight IP)的内存管理机制,在此基础上提出了一种基于该内存管理机制的底层网络接口收发模块的实现方法,并在开发板上进行了仿真测试,为将该协议栈成功移植到开源的μC/OS-Ⅱ嵌入式实时操作系统并最终实现基于LwIP协议栈的嵌入式Web服务器奠定了重要基础.

| Abstract: | This paper analyzes the memory management of light-weight interact protocol （LwIP） which is mainly applied in the embedded system. Also an approach is proposed to implement the sending and receiving module in the netwoi＇k interface layer based on this mechanism, and an experiment has been made to prove its effectiveness. This paper lays the foundation for replanting the LwIP TCP/IP stack into theμ/OS-Ⅱ real-time OS and the design of an embedded Web server based on this stack. |
