Replaced the cheap Netgear switch with a Cisco C2960CX. This increased the static offset from ~1.2μs to ~2μs. Interesting, and seems to corroborate asymmetric delay based on the network switch. I'd need to think a bit more on it and how it interacts with PTP's […]

@fasterthanlime Learned this one last week when it put multiple k8s nodes into disk pressure and broke everything. Fun times.

So far we've only synchronized the PHC on the NIC - the system can observe this clock, and it can be used to precisely timestamp network packets - but it is not coupled to the system's timekeeping yet.
In order to do that, we need a second control loop. In my current setup, that role is taken […]
