Abstract:
1. A method of checking the synchronization between at least two nodes Ni−1 and Ni in a network, each of the nodes having an internal clock having respective clock frequencies Fi−1 and Fi, and defining time cycles having respective durations of Ti−1=C init(i−1 /Fi−1 and Ti=C init(i) /Fi, where C init(i−1) and C init(i) each define a number of clock pulses, said method comprising the following steps: transmitting the frequency Fi−1 of the internal clock from node Ni−1 to node Ni, wherein transmission is effected by transmitting pulses generated by the internal clock of node Ni−1 to node Ni; determining a number of clock pulses C comparing the determined number of clock pulses C checking the synchronization between nodes Ni−1 and Ni using the result of the comparison between the determined number of clock pulses C
