As the timing data of local clock of the end system, the local time of the AFDX end system can be used to calculate the transmission delay of data frame between the transmitting end system and the receiving end system, thereby performing the verification of time integrity of the transmitted data frame.If the local time of the end system is lost, the verification of time integrity of the data cannot be performed.Based on the current health management of AFDX network and the design of time synchronization, a scheme of local time recovery based on the time stamp list is proposed.It has been verified that the recovery of local time of the end system can be realized, which can further ensure the verification of time integrity of the transmitted data in AFDX network and improve the reliability of the transmitted data.
