| Abstract: | The issue of meeting the higher communications requirements of future aircraft avionics systems in an incremental manner is addressed. A communications architecture is proposed which is based upon a switched network technology from the telecommunications area asynchronous transfer mode (ATM). However, the major step of migrating all existing avionics equipment into an ATM compliant form is avoided by the process of “emulating” a current avionics data bus such as MIL-STD-1553B over an ATM network. This allows current 1553 subsystems to co-exist with ATM compliant equipment on a single physical ATM network |
