说明：  通过对TCP/IP 协议的分析, 结合嵌入式系统的特点, 挑选出一套精简、实用的TCP/IP 协议子集, 并详细介绍各协议层 的实现过程。为嵌入式网络系统的开发提供一个较为简单且可行的思路。 关键词: 嵌入式系统, 以太网, TCP/IP 协议, UDP, ARP
(Through analyzing TCP/IP protocol and character of embedded system , it screens out a set of reduced and practical protocols, and introduces the process of realizing for each protocol- layer. It provides a feasible and simple method for exploiture of embedded network system.)
