基于双绞线的IP交换系统设计与实现

摘要

To aim at the pattern of TCP/IP network which is operated on the basis of LAN or WAN. After analysis of existing IP switch technology, it discusses the principle of IP switch system and puts forward a new IP switch technology based on UTP. According to this technology, a pure independent TCP/IP network which transported the IP packet through transmission medium directly was established, and the corresponding IP network switch was studied and designed, and the system of a 4 port IP switch based on UTP-5 was realized and cooperated debugging and function simulation between hardware and software were completed. The simulation results show that IP switch system has good performance and realizes the exchange forward of IP packet. It perfects the TCP/IP protocol system, simplifies the network architecture, and improves the transmission efficiency in network. Therefore, this system gives strong hardware support in realizing the IP switch technology based on UTP, and the study has deep theory meaning and practical application value.%针对目前计算机网络普遍采用在局域网或广域网的基础上运行TCP/IP网络的方式,在分析现有IP交换技术的基础上,探讨了IP交换系统的工作原理,提出了一种全新的基于双绞线直接传输IP分组的纯粹的独立的TCP/IP网络交换技术,设计与实现了与之相适应的四端口IP交换系统并进行了软硬件的协同调试与功能仿真；测试结果表明,IP交接系统性能良好,实现了IP分组的交换转发.达到了完善TCp/IP协议体系,简化网络结构,提高网络传输效率的目的,对实现全新的基于双绞线的IP交换技术提供了有力的技术支持,具有较重要的理论意义和实际应用价值.
