Abstract

   This document defines a YANG data model for the configuration of
   IEEE 1588-2008 devices and clocks, and also retrieval of the
   configuration information, data set and running states of IEEE
   1588-2008 clocks.

1. Introduction

   As a synchronization protocol, IEEE 1588-2008 (also known as IEEE
   1588v2) [IEEE1588] is widely supported in the carrier networks,
   industrial networks, automotive networks, and many other
   applications. It can provide high precision time synchronization as
   fine as nano-seconds. The protocol depends on a Precision Time
   Protocol (PTP) engine to decide its own state automatically, and a
   PTP transportation layer to carry the PTP timing and various
   quality messages. The configuration parameters and state data sets
   of IEEE 1588-2008 are numerous.
