Suppose I have PTP network adapters but vanilla switches and my network is lightly loaded. Can I filter out the delays in the switches by sending 10 packets and throwing out the ones with long delays? I'd expect the timings to be a cluster around the case where there was no delay in the switch and a tail for the ones that encountered some delay. I think it would be easy to filter out that tail. -- These are my opinions, not necessarily my employer's.
