摘　　要：国网95598异地双活系统中数据复制系统是国网为实现生产数据的灾备保护和保证业务系统的连续性的重要部分。而采用何种数据复制技术将直接影响数据复制系统在灾难来临时,对异地系统的切换能力和数据的复制的及时性。本文针对95598系统的数据复制的特点,提出了适用于异地双活系统的一种多级数据队列复制算法,实现不同优先级下数据的调度的及时、合理的调度。The data replication system in the State Grid 95598 off-site dual-active system is an important part of the State Grid to achieve disaster recovery protection of production data and ensure the continuity of the business system. The data replication technology will directly affect the data replication system's ability to switch to off-site systems and the timeliness of data replication in the event of a disaster. Aiming at the characteristics of data replication of 95598 system,this paper proposes a multi-level data queue replication algorithm to realize timely and reasonable scheduling of data scheduling under different priorities.
