文档介绍：基于TCP/IP的以太网通讯端口的设计
摘要
的发展,TCP/IP已经成为通信领域事实上的国际标准。嵌入式系统通过嵌入式TCP/,,将具有更好的实用性和巨大的经济效益。在对当前国内外嵌入式TCP/IP协议栈产品现状进行调研的基础上,自主研发了可利用TCP/IP协议进行数据传输的方法。本论文对ARP、ICMP、UDP、TCP等几个协议进行详细剖析,包括协议可配置性分析,并阐述TCP/IP协议栈的实现思路及方法。
TCP/IP协议栈采用分层体系结构,严格按照IEEE国际标准,没有任何私有协议,也没有做任何假设,从而确保协议的完整性和一致性。TCP/IP协议栈在设计上充分考虑了移植性,整个协议栈架构在系统抽象层之上,通过系统抽象层屏蔽掉硬件体系结构、底层嵌入式操作系统以及编译器等的差异。

The Design Of munication Interface On The Basis Of TCP/IP
Abstract
With the development of ,TCP/IP has virtually e the international standard in munication the connection,by means of embedded TCP/IP stack,between the embedded system and ,even e true,the embedded system will be much more practical and bring about enormous economic  on the research and study of the current situation of the embedded TCP/IP stack products home and abroad,independently the configurable embedded TCP/IP stack--VIP stack has been to VIP stack,this paper expatiates on ARP、ICMPv4、UDP、TCP and other protocols,including an analysis of protocol configuration,and also offers the implementation method of VIP stack..
VIP stack,with the adoption of layered architecture,can be carried out by means of ANSI C language,strictly abiding by international RFC standard without any private protocol and any assumption,so as to ensure integrality and consistency of the protocol  the aspect of design VIP stack takes full consideration of the property of  whole VIP stack stands on top of the system abstract layer,which eliminates the differences of hardware architecture,embedded operating system pilers. 
Keywords:  TCP/IP,  IP stack, IEEE standard
