民航数据通信的业务量和信息量在近几年来呈现出逐渐递增的趋势,所以在数据通信网中也提出了较多的新要求,不仅要面对不同的用户进行种类划分,还需要提高数据通信的速率。现如今民航数据通信网络的结构仍然是X.25,在这样的背景下数据传输必须要严格的遵守相关协议,限制了网络的利用率,导致资源浪费的现象,所以本文研究了DDN在民航数据通信中的应用,以提高民航数据通信网络的利用率。
The volume of civil aviation data communications and the amount of information in recent years showed a gradual upward trend in the data communications network also made more new requirements, not only to face different types of users, but also need to improve the data The rate of communication. Nowadays, the structure of civil aviation data communication network is still X.25. In this background, the data transmission must strictly comply with the relevant agreements, which limits the utilization of the network and leads to the waste of resources. Therefore, Communications applications to improve the utilization of civil aviation data communications network.
