Everything about Precision Time Protocol

Network time synchronization protocol

The Precision Time Protocol (PTP) is a protocol for clock synchronization throughout a computer network with relatively high precision as compared to using the earlier-developed Network Time Protocol (NTP) and therefore potentially higher accuracy depending on the configuration. In a local area network (LAN), accuracy can be sub-microsecond – making it suitable for measurement and control-systems applications. PTP can be used to synchronize financial transactions, mobile phone tower transmissions, sub-sea acoustic arrays, and networks that require precise timing as an alternative to using the timestamp of satellite navigation signals or where sub-nanosecond accuracy as provided by the White Rabbit Project is unnecessary.
