Network Architecture of National Airspace Data Interchange Network (NADIN).

The currently proposed National Airspace Data Interchange Network NADIN is to be a common user network to serve FAA data communication requirements. The initial development of the network must be oriented towards improving existing services as well as accommodating future requirements. The FAA has suggested the Service B network and the Aeronautical Fixed Telecommunications Network AFTN as two existing services whose integration is technically feasible, operationally attractive and financially beneficial. In particular, the need for improvement of the two services is urgent since the current load on the existing networks is near saturation. The purpose of this study is to examine the operational and technical feasibility of achieving the above objectives by developing an integrated network architecture. The study has resulted in a proposed network architecture which satisfies the objectives of Service B and AFTN and serves as a base for further NADIN development. Author
