Abstract:

The FSAS service was analyzed to determine NADIN enhancements required to support FSAS data communications. The analysis yielded the following conclusions 1 The NADIN backbone architecture fits FSAS needs and requires no change however, the NADIN switch to concentrator line speeds need to be increased from 4.8 to 9.6 Kbitssecond 2 The FSAS file transfers may cause relatively long delays to Service B and AFTN messages. By having the switches systematically intersperse frames of messages going to different concentrator input circuits, the delay effects of these file transfers can be minimized 3 Control of AWP message transmissions is recommended. Flow control will result in a more efficient use of the processing and memory resources of NADIN switches and 4 The AWP and FSDPS software should be designed to enable the AWPs to interrupt large weather file transmissions to send shorter messages.
