本文介绍了TCP/IP的结构及TCP/IP开放源代码的定义及特点,列出了TCP/IP开放源代码OpenTCP协议栈实现ARP地址解析、TCP及FTP功能的函数,并以ARP地址解析、TCP及FTP为例给出了实现其功能的软件流程。最终举出了OpenTCP协议栈在Freescale公司的以太网芯片MC9S12NE64上实现TCP通讯的应用实例,结论证实了OpenTCP协议栈在MC9S12NE64芯片上能够稳定实现以太网通讯。
This paper introduces the structure of TCP / IP and the definition and characteristics of TCP / IP open source. It lists the functions of TCP / IP open source OpenTCP protocol stack to implement ARP address resolution, TCP and FTP functions. With ARP address resolution, TCP and FTP as an example to give the software flow to realize its function. The paper finally shows the application of OpenTCP protocol stack to implement TCP communication on Freescale’s Ethernet chip MC9S12NE64. The conclusion proves that the OpenTCP protocol stack can stably implement Ethernet communication on the MC9S12NE64 chip.
