摘要

本文提出了一种主冗余技术来提高ieee1588中同步的可用性。针对主从节点之间的链路拥塞问题，提出了一种新的最佳主时钟算法。为了确定主节点的优先级，使用了基于改进的IEEE 1588消息序列的BMC算法和简单的链路拥塞估计。通过数值仿真验证了主冗余技术的有效性。

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.
