摘要
一、概况中国民航的计算机数据通信网从1985年开始建设,是伴随民航旅客服务及航空货运计算机系统的建立而发展起来的,因此从起步始就按照面向多应用系统的指导思想,以适应不同计算机硬件平台的可联接全球广域地区终端的分布式实时数据通信网的原则进行规划和设计,使网络系统对民航计算机的各个应用系统具有相对独立性。不仅成为民航数据传输专用网,也为社会其他领域计算机应用提供一个开放性的网络。
It's ten years since the computer information network of CAAC was established.It has been connected initially for passen- ger services and cargo transportation including a network constructure—“an organic whole of universe” combined with cable, fiber,microwave network and satellite network,to be complement and spare mutually.At present,there are 16 airlines and over 700 service networks at the sales points extended to 130 cities at home and abroad with 5,700 network-con-necting equipments, becoming a computer network system which is the biggest in scale for the coverage of network connection as well as quick response on-line.The network will be developed towards the opening-up direction so as to serve more applied fields and the network con- nection of different computer information platforms for CAAC and the society,turning it into a component part of the “ex- pressway of national information” which is being constructed in our country.
