AFDX性能分析与调度算法
The Performance Analysis and Scheduling Algotithm of AFDX
摘要
Abstract
Nowadays,full duplex switched Ethernet (AFDX) as a new generation of avionic bus technology with high real-time and high reliability is put forward.The key technologies of AFDX are analyzed.In accordance with the different types of avionic messages,the different priorities are provided for the event messages that has different delay requirements.AFDX network transmission model is established to simulate the message transmission by using stochastic Petri net,and the crucial parameters such as network load and average waiting time are analyzed.According to the specialties of AFDX,the queuing mechanism based on the message arriving is presented,and a new scheduling algorithm is designed to meet a higher demand of reliability and real-time ability.关键词
