摘要
结合中国民航自动转报业务使用X．25的情况、布局及应用中存在的问题，介绍分组交换和帧中继的技术特点，并通过分组交换与帧中继的比较，说明帧中继正取代分组交换而成为今后中国民航数据通信网的主要数据交换技术。
This paper gives an account of the technological characteristics of packet switching and frame relay in connection with the distribution and application of, as well as the existiing problems in using, the automatic message relay in the Chinese civil aviation industry. The comparison between packet switching and frame relay indicates that the latter will replace the former as the chief transmission technology of the data communication networks in China's civil aviation industry.
