Abstract

Abstract: In order to improve the reliability of clock synchronization, based on the IEEE 802.1AS protocol, a method for the nearest port master clock backup and the master clock phase offset hot backup redundancy method is proposed. Simulation shows that the recent port master clock backup method is 38% more reliable than the standard master clock reselection method, and the master clock phase offset hot backup redundancy is 48% more accurate than the standard hot backup redundancy method.

Key words: clock synchronization, redundancy, phase, nearest port, reselection
