The Precision Time Protocol, PTP, is designed to synchronize clocks on a local area network (LAN) to sub-microsecond precision. The underlying assumption is that the accurate time source is on the same LAN as the systems that are synchronizing their clocks. That differs from NTP, which assumes that the time server is ... scott foxwell

"WebNov 27, 2024 · End to End means the latency through the network is calculated directly between master and slave. This allows for PTP to operate over networks with Transparent clocks, non-PTP aware network switches, or a combination of both. The slaves sends delay requests upstream to the master, the master responds, and the network latency is … " - Ptp ingress latency
