4.7.1 Precision time synchronization (PTP)
Time synchronization from a master clock synchronized to the global positioning
satellite (GPS) system is accepted over the network according to IEEE/IEC61588 Ed.2.
(2009).
PTP synchronizes all clocks within a network by adjusting distributed clocks to a
grandmaster clock. PTP enables distributed clocks to be synchronized and maintained
to sub-microsecond accuracy.
Figure 11: Example of PRP/HSR Architecture with the Precision Time Protocol (PTP)
Note:
On PTP protocol, a time discrepancy of 60 milliseconds per 24h is reported on Reason H49 (equipped with a SRPv3 version x) and
used as Master Clock (M1) (case VDAN-P Grandmaster Clock not available).
