本文件介绍了一个TCP/IP的功能，设计要点，本协议栈实现的组件包括ARP，I CMP（PING），UDP，TCP。并设计了一个与SOCKET API兼容的标准接口。



TCP/IP协议栈背景

TCP/IP是使用最为广泛的INTERNET通信协议，几乎所有的桌面操作系统如Windows，Redhat Linux都支持TCP/IP协议。为了实现嵌入式系统与PC机的组网通信，就必须在嵌入式系统上实现复杂的TCP/IP协议栈，通过实现了TCP/IP协议栈，就可以方便的实现嵌入式系统与主流桌面操作系统的通信和资源共享，这也是作者编写TCP/IP协议栈的由衷。

-Introduction This document is a TCP/IP functionality, design elements, realize the protocol stack components including ARP, I CMP (PING), UDP, TCP. And designed a SOCKET API-compatible with standard interfaces. TCP/IP protocol stack background TCP/IP is the most widely used communication protocol INTERNET, almost all of the desktop operating system such as Windows, Redhat Linux support TCP/IP protocol. In order to realize embedded systems and PC-letter Netcom Group, we must realize the complexity of embedded system on the TCP/IP protocol stack, through the realization of the TCP/IP protocol stack, we can facilitate the realization of embedded systems with mainstream desktop operating system of communication and resource sharing, this is also author of the preparation of TCP/IP protocol stack heartfelt.
