PTP/IEEE-1588 Slave Software

The Precision Time Protocol (PTP) is a relatively new protocol.  As such, there are very few options available for you to use for Slave Clock software.  The widely available software is an open source version which is listed in the table below.  A Windows version of PTP Slave software is available for you to purchase from another vendor (see below).

For an explanation of PTP/IEEE-1588 please read our "Precision Time Protocol" white paper.


Windows XP, 2003, VISTA, Windows 7
(PTPv2 only)
Choices for PTP Slave software on Windows machines are very limited.  Windows is not a real-time operating system and synchronization is dependent on the CPU and the operating system version.  PTP Slave software is available from Greyware and is called Domain Time II.  Your PTP Slave can be synchronized to within one millisecond of the Grandmaster (network topology dependent) using this software.


Linux
(PTPv1 and PTPv2)
PTPd is freely available at Sourceforge and is a complete implementation of the IEEE-1588 specification for a standard clock.  Source code for PTPd is open source and because of contributions from users it is becoming an increasingly portable, interoperable, and stable IEEE-1588 implementation.  Your PTP Slave can be synchronized to within 10 microseconds of the Grandmaster using this software (network topology dependent).
