DISTRIBUTED SYNCHRONIZATION METHOD AND SYSTEM

摘要

The invention relates to a distributed synchronization method in a communications network comprising a number of stations that exchange messages with one another. The inventive method comprises at least the following steps: inserting into each message transmitted by a transmitter, a synchronization pattern characteristic of the time reference of the transmitter, and; updating the time reference of each station with the time reference it receives from another station of the network if and only if the time received is ahead of the time reference. The updating ensues in the following manner: calculating the difference <X=T'a-Ta between the transmission time T'a of the message received by a station A and the receiving time Ta of the same message by station B, and; applying a correction 0<?Y<=?X if the transmission time received is ahead of a value of at least tau (??> tau >0).
