Synchronization Performance ofthePrecision TimeProtocol

Thispaperanalyzes thefactors thataffect the synchronization performance inusing thePrecision Time Protocol (PTP). Wefirst study theinfluence ofjitter under theassumption ofnofrequency drifts. Thenwestudy the influence offrequency drift intheabsence ofjitter. The analytic formulas provide a theoretical ground forthe understanding ofsimulation results aswell asguidelines for choosing bothsystemand control parameters when applying PTP.
