Performance Comparison of the Future Aeronautical Telecommunications Network and the Interim AEEC ARINC Specification 622/ACARS Network

摘要

The intent of this paper is to provide a comparison between the anticipated performance of the interim AEEC ARINC Specification 622/ACARS/SATCOM data link and its successor, the Aeronautical Telecommunications Network (ATN). Performance parameters studied include capacity, end-to-end transit delay and throughput with a focus on handling of safety data. Computer models were used to simulate each system and collect all performance data. In order to make a valid comparison, a common traffic model was employed and common configuration was chosen for the AMSS which is the air/ground satellite subnetwork utilized by both systems. This paper compares the anticipated performance of the two systems and highlights the advantages of the ATN. It is evident from the results presented herein that ATN offers higher capacity, better transit delay performance and superior throughput performance compared to the interim data link, and the gains from ATN are most pronounced for longer data message lengths.
