Abstract

The present invention proposes a method for generating a synchronous message, including: when receiving a synchronous Sync message, setting the identification information of the Sync message in the Sync message, and sending the Sync message to The first synchronization device; receiving the identification information fed back by the first synchronization device and the time synchronization information corresponding to the Sync message; when confirming that the Followup message corresponding to the Sync message is received based on the identification information , setting the time synchronization information in the Followup packet. The invention also discloses a synchronization device and a computer-readable storage medium. By implementing the above scheme, the network communication device can carry time synchronization information in the Followup message according to the two-step PTP protocol standard, so as to realize the network communication device based on Two-step PTP protocol standard for time synchronization.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for generating a synchronization message, a synchronization device and a computer-readable storage medium. Background technique [0002] In a communication network, the normal operation of many services requires communication network devices to perform time synchronization, so as to keep the time or frequency difference between devices in the entire communication network within a reasonable error. PTP (Precision TimeProtoco1, Precision Time Protocol) is a network time synchronization protocol with sub-microsecond level time synchronization performance. [0003] The PTP protocol includes two PTP protocol standards, one-step method and two-step method. Some current communication network devices are limited by hardware and / or software, and cannot perform time synchronization according to the two-step PTP protocol standard. They only obtain the time stamp specified in...
