| Abstract: | The requirements of a highly reliable data transport mechanism are outlined, and a practical implementation of the CCITT/ISO standards within the airline is demonstrated. An understanding of the ISO Open Systems Interconnection architecture, as well as CCITT recommendations such as X.25 and X.75, is assumed. The selection of various X.25 subsets and how they meet the data communications needs of a variety of interconnection structures are then described. Finally, the paper reviews the current work being undertaken with respect to the higher layers of the ISO OSI architecture. |
