Message synchronizing method, device and system

Abstract

Embodiments of the present invention relate to a message synchronization method, apparatus and system. The method includes: obtaining a first sending time stamp transmitted on a main link and a second sending time stamp transmitted on a backup link respectively; calculating to obtain a time difference according to the first sending time stamp and the second sending time stamp; adding bytes to the first message transmitted on the main link and the first message transmitted on the backup link, and form second messages to be transmitted on the main link and the backup link respectively; and sending the second messages to a receiving end on the main link and the backup link respectively. According to the message synchronization method, apparatus and system provided in the embodiments of the present invention, when errors occur in the second message on the main link and are uncorrectable, the receiving end may receive the second message through the backup link, modify a second receiving time stamp on the backup link according to the time difference in the second message, so that the receiving end may obtain the same receiving time stamps on the main link and the backup link, thereby implementing the synchronization process of the messages.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, in particular to a message synchronization method, device and system. Background technique [0002] With the development of Internet Protocol (Internet Protocol, IP for short) in future networks and services, various technologies for clock synchronization and time synchronization on the IP network are also developing rapidly. Among various packet clock technologies, the 1588V2 protocol of the Institute of Electrical and Electronics Engineers (IEEE for short) is gradually adopted in carrier-class communication equipment because it can provide time synchronization with microsecond precision. The 1588V2 protocol realizes the time synchronization of the network elements at both ends of the communication link by transmitting 1588V2 messages on a single communication link. If the communication link is interrupted, the 1588V2 protocol will switch to another normal communi...
