That precision probably requires a specifically designed PTP-aware switch, or a direct cable connection between two devices. It would also require adding the hardware TX timestamp support. With a generic TP-Link Ethernet switch, I'm seeing packet delays of several microseconds and with 1-2 microsecond variation. The delay measurement and averaging can compensate a bit, but I don't think 50 ns is achievable with generic Ethernet switches. -- This is an automated message from the Apache Git Service.
