TCP/IP协议(传输控制协议与网际协议),是异种计算机网络彼此通信的重要协议.而著名的ISO/OSI(国际标准化组织/开放组织互连)标准,被公认为是计算机网络的发展方向,但目前对为数众多又互不兼容的计算机和网络之间的通信来说,OSI标准还不健全,符合OSI标准的软硬件产品也很不丰富,因而尚无法实现多种异种机异种网之间的通信.在与ISO模型有关的普通协议中,X.25协议是最有名的,被公共数据网络所采纳.现就目前这两种协议共存的情况,对于它们各自在构筑通信网络时所采取的对传
The TCP / IP protocol (Transmission Control Protocol and Internet Protocol) is an important protocol for heterogeneous computer networks to communicate with each other and the well-known ISO / OSI (International Organization for Standardization / Open Organization Interconnection) standards are recognized as the direction of computer networks , But OSI standards are still not perfect for communication between a large number of incompatible computers and networks. The software and hardware products conforming to the OSI standard are also not rich, so that it is not possible to realize a variety of heterogeneous networks Among the common protocols related to the ISO model, the X.25 protocol is the most well-known and is adopted by public data networks.With the coexistence of these two protocols, Take the pass
