Abstract
This thesis presents the evolution of Aircraft Data Networks .It describes various Avionics data network protocols based on the Avionics systems architecture. It discusses the evolution from a simple point-to-point protocol presented in ARINC 429 to a shared data bus protocol presented in ARINC 629. Finally, the new Data network based on AFDX (Avionics Full-duplex Ethernet) is discussed. AFDX is a new standard based on Ethernet technology and able to handle today’s requirements.
Comparison between the three different protocols is presented. The comparison shows that AFDX provides better performance and flexibility without losing the compliance with safety, redundancy and reliability of Avionics requirements.
A proposed simulation model for AFDX network components is presented. It is based on OPNET platform. A case study network is introduced. This case study is used to evaluate AFDX performance. End-to-End delay analysis for AFDX network is introduced. Different terms that affect End-to-End delay are discussed.
The AFDX Case study network is implemented using ARINC429 and comparison between the two networks is presented. It shows the differences in performance, topology, reliability, redundancy and flexibility. Comparing AFDX with the other standard, it is the highest speed and throughput .Also; it complies with safety, redundancy and reliability of Avionics requirements
