【Abstract】This paper concentrates on the construction of AFDX End System(ES) and brings out a sound framework based on analysis of crucial
techniques of AFDX protocol. It designs and implements Tx protocol processing algorithm and traffic shaping-scheduling algorithm of key modules
in AFDX ES for address mapping and real-time mechanism. The results of simulation on Linux OS confirm that this framework can meet reliability
and real-time requirements of avionics data transmission.
【Key words】AFDX protocol; deterministic property; protocol simulation
