WebSep 13, 2011 · The PTP ( Precision Time Protocol ), uses Sync message then Follow-up message, as described in the article "Understanding the IEEE 1588 Precision Time Protocol". I don't understand why do we need Follow-up message in part A in Figure 1. I think that using only Sync message is enough. I hope that someone can explains this to … Web– GM-capable stations advertise that fact via ANNOUNCE messages – If station hears from station with “better” clock, does not send ANNOUNCE • Settable “Priority” field can override clock quality • MAC address is tie breaker – Bridges drop all inferior ANNOUNCE messages • Forward only the best

Webptp Precise Time Protocol (PTP) PTP is used to synchronize the clock of a network client with a server (similar to NTP). However, PTP is mainly used in LANs, with much higher precision than NTP (usually 10's of microseconds to 10's of nanoseconds). Is is specified in IEEE 1588.
