Introduction

This software is an implementation of the Precision Time Protocol (PTP) according to IEEE standard 1588 for Linux. The dual design goals are to provide a robust implementation of the standard and to use the most relevant and modern Application Programming Interfaces (API) offered by the Linux kernel. Supporting legacy APIs and other platforms is not a goal.

License

Goals and Features

  • Supports hardware and software time stamping via the Linux SO_TIMESTAMPING socket option.
  • Supports 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).
  • Modular design allowing painless addition of new transports and clock servos.
