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. csl plasma work from home jobsWeb1 Types and Format 1.1 PTP Header 1.2 PTP Suffix 2 Sync message 2.1 the Ethernet header 2.2 the IP header 2.3 the UDP header 2.4 the PTP header 2.5 the PTP body 3 Follow_Up message 4 Delay_Req message 5 Delay_Resp message 6 References Types and Format Below only the four most important messages are explained in detail. csl plasma workday appWebThis correction is based on the difference in the timestamp generated when the event message enters and leaves the transparent clock.
