PTP is way better than NTP, but it might be possible that reference time is somehow taken from NTP anyway.
What I Mean:
Reference .gov atomic clock (not radium one) -> NTP -> ? -> ? -> satellite control station -> gps -> PTP
Hahaha
- great_wubwub 11mo agoPTP is more precise so it's much harder to synchronize over long distances. Even in data centers it benefits from hop-by-hop participation from the routers involved.
- jhellan 11mo agoThis is true when all network delays between the synchronized device and the time reference are deterministic and accounted for in the configuration. The design of PTP assumes that this is the case. NTP, on the other hand, estimates the network delays to its time references. Is there any reason to believe that PTP would be better in normal networks?
