When I first started looking, I noticed a distinct trend in information on PTP. Personally, I think that the general consensus on PTP is wrong. Namely, PTP isn’t that complicated to get setup, it doesn’t require a hardware clock, nor does it require any specific hardware support. If you want to get to sub-microsecond precision, some of those things may become important, but a basic setup doesn’t require that. Of course, if you want to get down to the advertised nanosecond-level (or in the case of White Rabbit extensions, 100s of picoseconds) precision, then you probably do need some of that, but not all of it.
