Modelling and Performance Analysis of AFDX Messages with Priority
摘要
Abstract
By using the Petri Nets as the tool, the paper establishes the Petri Net (PN) model of AFDX network (Avionics Full Duplex Ethernet) which is based on priority messages transmission. After simulation and solution of the Petri Net model,is provided a performance index-average waiting-time in the sending process of messages with different priorities. The obtained results verifies the average waiting-time of high priority data frame is much shorter than the low priority to send a message. The analysis of the performance fully shows the priority importance of the emergency data with which has very high realtime requirements in the harsh environment for avionics. It helps to further understanding of the messages with different priorities transmission mechanism of AFDX network by the PN model. The important theoretical basis for design and improve avionics system in which uses the AFDX is Provided.关键词
