Gptp correctionfield
WebJul 31, 2024 · Rather than acting as a multi-port ordinary clock as boundary clocks do, transparent clocks update a newly introduced time-interval field within PTP event messages. This 64-bit time-interval correction field allows for switch delay compensation to a potential accuracy of less than one picosecond. WebPTP Background and Overview 2 PTP PTP fills a clock-synchronization need between NTP and GPS-based clock synchronization, with accuracy to 1 μs. There are two reasons to use PTP instead of GPS. One is that in a PTP network only one GPS receiver is needed, which is less expensive than giving each network node its own GPS receiver.

WebgPTP uses the exchange of time-stamped messages to communicate time from a master clock to a number of bridge and end-point devices. The time-stamped messages are SYNC, PEER_DELAY_REQ and PEER_DELAY_RESP as shown below. Distinct from other PTP implementations, gPTP also uses time-stamped messages to calculate frequency offsets …
