Hi,
I'm seeking for a sponsor for linuxptp which I started to package
recently[1]. Maybe someone from the NTP folks is interested to jump in.
Here is the package description for further details:
Description: Precision Time Protocol (PTP, IEEE1588) implementation for
Linux
Linuxptp is an implementation of the Precision Time Protocol (PTP)
according to IEEE standard 1588 for Linux. Features include:
- support for hardware and software time stamping via the Linux
SO_TIMESTAMPING socket option.
- supports for the Linux PTP Hardware Clock (PHC) subsystem by using the
clock_gettime family of calls, including the new clock_adjtimex
system call
- implements Boundary Clock (BC) and Ordinary Clock (OC)
- transport over UDP/IPv4, UDP/IPv6, and raw Ethernet (Layer 2)
- supports IEEE 802.1AS-2011 in the role of end station
PTP provides higher precision and faster synchronization than NTP even
without hardware support. With hardware support, sub-microsecond accuracy
can be expected. Whereas NTP is intended for WAN use, PTP is designed for
LAN use and makes use of UDP multicast.
A driver support matrix can be found on
<http://linuxptp.sourceforge.net/#outline-container-5.3>.
