57 Zusammenfassung AB [EN] A method for handling at least one encapsulated synchronization message (6) by a tunnel node (1-4) including a transparent clock, said method comprising the following steps: - generating a signature (7) from the encapsulated synchronization message (6); - generating, or updating if it has already been generated, a tunnel follow-up message (8) which includes the encapsulated synchronization message signature (7); - measuring the encapsulated synchronization message residence time across the tunnel node (1-4); - updating the correction field of the tunnel follow-up message with the measured residence time.
