Facebook open-sourcing a more precise time server
It looks like the source for their FBOSS agent that runs on switches will enable PTP in two kinds of supported switches:
https://github.com/facebook/fboss/blob/master/fboss/agent/hw...
They have O(thousands) of switches (source: https://engineering.fb.com/2016/10/18/data-center-engineerin...) so IIRC they get the per-switch cost down by doing a custom design to reduce BOM. I believe the specs and designs are available under the Open Compute project here (search for "Facebook"): https://www.opencompute.org/wiki/Networking/SpecsAndDesigns
What are some alternatives?
