Patent ID: 8649303

Claim:
A method for transmitting synchronization frames in a communication network in order to permit synchronization of a local clock of at least one equipment item connected to the communication network with a clock of a reference equipment item also connected to the communication network, the at least one equipment item, separate from the reference equipment item, being connected to the reference equipment item via at least one switch, the method, employed in the at least one switch, comprising: calculating a calculated transmission delay to be different than a fixed transmission delay when a previous transmission delay of a synchronization frame that was previously transmitted by the at least one switch is also different than the fixed transmission delay; receiving at least one synchronization frame emitted by the reference equipment item, the at least one synchronization frame including a time point of emission of the at least one synchronization frame according to the clock of the reference equipment item; and transmitting the at least one received synchronization frame after the calculated transmission delay from the reception of the at least one synchronization frame by the switch, the local clock of the at least one equipment item, after reception the receiving of the at least one synchronization frame by the at least one equipment item, being synchronized according to at least the time point of emission, a time point of reception of the at least one synchronization frame at the at least one equipment item, and the fixed transmission delay.
