摘　　要：传统大型数据中心实现异地双活是一种必要的发展趋势,具有资源利用率高、业务连续性好和灾备能力强等特点。针对高并发访问、海量数据处理、应急响应和灾难快速恢复等要求,国家电网公司适时提出了95598核心业务异地双活系统的建设方案。以此为基础,介绍了异地双活环境下GTM全局负载均衡总体逻辑架构,并遵照该架构介绍了包括基于DNS域名解析、OSB企业服务总线和全局路由表的3种GTM设备全局负载均衡关键技术。最后,兼顾考虑省市接入距离和数据中心最大负载量利用率,提出了一种基于logistic回归模型预测潜在用户数量的省市用户优化接入方法。The implementation of remote dual-activity for traditional large-scale datacenters is a necessary development trend,it has the advantages of high resource utilization,good business continuity and strong disaster recovery capabilities.In response to the requirements of high-level concurrent access,massive data processing,emergency response and rapid disaster recovery,the State Grid timely puts forward a construction scheme of the remote dual-active system for the 95598 core business system.Based on this system,this paper introduces the overall logic architecture of GTM global load balancing under the remote dual-activity,and describes the global load balancing design in detail which includes three key technologies for global load balancing based on DNS domain name resolution,OSB enterprise service bus and global routing table.Finally,taking into account the access distances of provinces and cities and the maximum load utilization rate of data centers,an optimized access method for provinces and cities based on the logistic regression model to predict the number of potential users is proposed.
