Splitting the Ping

This reminded me of the buffer bloat[0] problem esr was talking about a few years ago.

I thought I read a paper where he was getting hardware made for the purpose of using gps for time so it could be accurate enough to measure latency. I just googled and I realized it wasn't a paper, it was a talk I went to in 2012 that I forgot about[1]

I wonder if anything came of it, does anyone know?

This "not quite 5 minute guide to making an NTP server" is from 2014: https://ava.upuaut.net/?p=726

So GPS boards for Raspberry Pi were cheap off-the-shelf hardware by 2014, at least.
