====== Precision Time Protocol (PTP) ======
[[dido:public:ra:xapend:xapend.a_glossary:start| Return to Glossary ]]

The **Precision Time Protocol (PTP)**, as defined in the [[dido:public:ra:xapend:xapend.b_stds:tech:ieee:1588]] standard, provides a method
to precisely synchronize computers over a Local Area Network (LAN). **PTP** is capable of
synchronizing multiple clocks to better than 100 nanoseconds on a network specifically
designed for IEEE-1588. A Network Time Server with **PTP** is typically referred to as an
“IEEE-1588 Grandmaster” or “PTP Grandmaster”. This paper describes basic principles
of **PTP**, information on using dual Grandmasters, and the requirements of the network to
achieve sub-100 nanosecond time synchronization.
