Analysis of AFDX Network Delay Based on NS2

Abstract

AFDX network simulation is of great significance for evaluating and determining whether AFDX can meet the real-time requirements of avionics networks. Compared with theoretical analysis methods such as network calculus, network simulation can better understand the true behavior of the AFDX network. In this paper, we build an AFDX network simulator based on NS2, where AFDX switches, end systems and virtual links are properly modeled. Using this simulator, the end-to-end delay of an AFDX network under different scheduling strategies is studied. Some key performance measures of the system are also analyzed.
