Abstract

AFDX (Avionics Full Duplex Switched Ethernet) as the new generation avionics databus, represents a major improvement in bandwidth and security. With the development of avionics system, delay jitter is becoming a more and more significant indicator for the designer. This paper presents a new re-shaping (RSP) method to reduce delay jitter by assigning fixed transmission order to different virtual links based on historical information and priority. Compared with traditional scheduling algorithms FIFO (first in first out), RSP effectively reduces delay jitter in the scenario of conflict of different virtual links.
