Grandsource Clock (Primary Clock) is the primary source for clock. So, what are these PTP Clocks? These are given below: With these PTP clocks, there is a hierarchical structure between different clocks. In a PTP network, there are different PTP clocks.

To test your networking knowledge, you can visit our All NEtwork Quizes Page! There is a hierarchy between the clock sources in PTP network. PTP works with master slave architecture. This accuracy let Precision Time Protocol used in critical systems like financial transactions, aircraft monitoring. Because NTP provides only millisecond accuracy. PTP accuracy is higher than NTP (Network Time Protocol) accuracy.

PTP clock accuracy is in the sub-microsecond range. PTP (Precision Time Protocol) is basically used for the clock synchronization throughout a computer network. It is a standard based network protocol defined as IEEE-1588 standard. PTP is the abbreviation of Precision Time Protocol.
