Delay-Aware Hybrid Consensus Time Synchronization

首发时间:2024-03-29
Abstract:In contemporary distributed systems, ensuring precise time synchronization is critical for coordinating operations, optimizing resource allocation, enhancing data consistency, and supporting temporal analysis. Traditional synchronization methods, such as central clock sources or simple broadcasting protocols, struggle to meet the demands of increasingly complex and dynamic network environments, especially in large-scale, highly variable, and energy-constrained settings. To address these challenges, this paper introduces a hybrid consistency time synchronization algorithm(DA-HCTS) ) that combines the strengths of Maximum Consistency Time Synchronization (MTS) and Average Consistency Time Synchronization (ATS), incorporating delay considerations. This approach quickly aligns all nodes to the network\'s maximum clock value for swift synchronization while averaging clock deviations for long-term precision and stability, offering an innovative solution to enhance synchronization accuracy and robustness in dynamic network environments.

基于时延的混合一致性时间同步
摘要:在现代分布式系统中,确保精确的时间同步对于协调操作、优化资源分配、增强数据一致性和支持时间分析至关重要。传统的同步方法,如中心时钟源或简单的广播协议,在应对日益复杂和动态的网络环境,尤其是在大规模、高度可变和能源受限的设置中,难以满足需求。为了解决这些挑战,本文引入了一种混合一致性时间同步算法(DA-HCTS),结合了最大一致性时间同步(MTS)和平均一致性时间同步(ATS)的优点,并考虑了延迟因素。这种方法快速将所有节点对齐到网络的最大时钟值,以实现快速同步,同时通过平均时钟偏差以提高长期的精度和稳定性,为在动态网络环境中增强同步的准确性和鲁棒性提供了创新的解决方案。。
