摘　　要：互联网采用TCP/IP协议,将众多采用以太网技术组成的局域网互联起来,构成了遍布全球的广域网络,是当前信息社会的重要基石。基于此,笔者从子络内部与跨网络通信两种情况出发,探讨了数据从一个主机传送到另一个主机的方式,从而为实现全网通信提供技术支持。掌握通信主机双方数据包的传递过程,对了解计算机网络的工作机理、排除计算机网络故障、优化网络配置等都有帮助。The Internet is an important cornerstone of the current information society,which adopts the TCP/IP protocol.It connects many local area networks which are made up of Ethernet technology to form a global wide area network.Based on this,the author discusses the internal and cross network communication of sub network,and discusses how to transfer data from one host to another,so as to realize the whole network communication.It is helpful to understand the working mechanism of computer network principle,troubleshooting of computer network,optimizing the configuration of network and so on.
