摘要

针对现有IEEE 802.1AS协议中单一主时钟无法保障多跳网络下高精度同步的问题，提出一种基于多属性决策的冗余时钟同步方法.首先，基于链路拥塞程度、节点拓扑属性和时钟源质量系数对时钟属性值进行建模；其次，采用多属性决策算法选取最佳主时钟并生成冗余时钟序列表；最后，利用FPGA（Field Programmable Gate Array）平台设计并实现冗余时钟同步系统，同时搭建真实网络环境对所提方法进行测试.结果表明，相较于现有方法，时钟同步精度提升了68%，主时钟失效后重新同步所需收敛时间减小了60%.

Abstract

Aiming at the problem that a single master clock in the existing IEEE 802.1AS protocol cannot guarantee the high precision of clock synchronization in multi-hop network

a redundant clock synchronization method based on multi-attribute decision-making is proposed. Firstly

the clock attribute value is modeled based on the link congestion degree

topology attribute of node and clock source quality factor. Secondly

the multi-attribute decision-making algorithm is used to select the best master clock and generate a redundant clock sequence table; Finally

the redundant clock synchronization system is designed and implemented on field programmable gate array (FPGA) platform

and a real network environment is constructed to test the proposed method. The results show that

compared with the existing methods

the clock synchronization accuracy is improved by 68%

and the convergence time required for resynchronization after master clock failure is reduced by 60%.
