摘　　要：铁路局级客票系统目前部署于铁路局的同一物理机房,系统处于单中心运行状态,一旦机房环境出现故障,客票业务连续性难以保障。本文着重分析和研究铁路局级客票系统业务、结构和数据同步关系;结合虚拟化技术,设计了铁路局级客票系统双中心双活架构,该架构具备系统可靠性高、系统规模扩展灵活、系统处理能力快速等优点。Generally, the Ticketing and Reservation System （ TRS ） for level of railway administration was arranged in the same server rooms, accordingly, the System worked under the pattern of single center. It meant that the continuity work of the System couldn＇t be guaranteed if the environment of the server rooms were breakdown. This paper researched on the business, structure and relationship of data synchronization about the System, Combined with virtualization, a double active centers architecture of the System was designed. This architecture was with the advantages of high reliability, flexible to expand and rapid processing capacity.
