PTP (Precision Time Protocol) is more precise than NTP. PTP is used in systems requiring high accuracy, such as financial trading or telecommunications, providing clock synchronization within nanoseconds.

FAQs & Answers

  1. What are the main differences between PTP and NTP? The main differences lie in precision and usage; PTP offers nanosecond accuracy, while NTP typically provides milliseconds.
  2. What applications benefit most from PTP? PTP is utilized mainly in high-speed trading, telecommunications, and broadcasting, where precise timing is critical.
  3. Can NTP be used in high-precision environments? NTP can be used but may not meet the stringent accuracy requirements compared to PTP in high-precision environments.
  4. How does PTP achieve higher accuracy than NTP? PTP achieves higher accuracy by using hardware timestamping and a master-slave hierarchy, reducing network delay effects.
