ABSTRACT:
The invention concerns a method of checking the synchronization between at least two nodes Ni−1, Ni, with i=1, . . . , n in a network, each of said nodes having respectively an internal clock having a respective clock frequency Fi−1, Fi, wherein said method includes the following steps:a) transmitting the frequency Fi−1 of the internal clock from the node Ni−1 to the node Ni,b) comparing the frequency Fi−1 of the internal clock of the node Ni−1 transmitted to the node Ni with the frequency Fi of the internal clock of said node Ni,c) checking the synchronization between the nodes Ni−1 and Ni using the result of the comparison between the frequencies Fi−1 and Fi.
