<p>A network element (30) for a packet-switched network comprises: a plurality of network ports (31, 32) for exchanging synchronization messages with further network elements,
a local clock (41),
a timestamp generation module (36) associated to each network port for triggering generation of a timestamp, and
a synchronization control module (43) selectively configurable in a first operating mode and a second operating mode as a function of a configuration signal,
wherein the synchronization control module configured in the first operating mode is adapted to adjust an offset of the local clock as a function of the timestamps of the synchronization messages received through the slave port,
and wherein the synchronization control module configured in the second operating mode is adapted to compute a residence time of a synchronization message in the network element as a function of the timestamps obtained at the time of receiving and sending the synchronization message.</p> |
