Abstract

This paper focuses on key technique in avionics data bus AFDX protocol——Virtual Link Scheduling Algorithm.We give AVLSP

AFDX Virtual Link Static Priority scheduling algorithm

to improve the performance of AFDX networks.Network Calculus theory is used in modeling and analyzing AVLSP.A simulation platform is also constructed to test the algorithm.The final results confirm that

AVLSP algorithm can effectively reduce transmission delay of emergency data and satisfy needs for real-time data transmission in avionics data networks.
