A master redundancy technique in IEEE 1588 synchronization with a link congestion estimation

This paper presents a master redundancy technique for improving the availability of synchronization in IEEE 1588. We propose a novel best master clock (BMC) algorithm to take account of link congestion between master and slave nodes. To determine the priority of master nodes, a BMC algorithm with a simple link congestion estimation based on a modified IEEE 1588 message sequence is used. The effectiveness of the proposed master redundancy technique is demonstrated by numerical simulation.
