铁路调度系统虚拟化应用平台研究

Study of Railway Dispatch System Virtualization Application Platform

以调度业务应用服务化和存储资源、服务计算资源、客户端资源等硬件资源虚拟化为切入点,研究层次化的虚拟资源管理和以应用服务化支持下的应用域结构的铁路调度系统虚拟化应用平台,根据基于应用域的资源配置策略提出调度系统建设初期的存储资源负供应策略,针对计算资源提出了负载驱动的预案式资源配置策略,以服务化为支撑的客户端资源部署策略。通过基于SOA架构的调度业务服务化与硬件资源虚拟化,实现对铁路调度系统资源高效合理配置。

Started from the researches on service-oriented dispatching business applications and virtualization of hardware resources,including storage resources,computing resources,and clients＇ resources,we studied a virtualized application platform for railway dispatching system,which realized layered virtual resource management based on application domain structure and resource allocation strategies.The paper proposes a negative supply strategy for storage resources at the early construction stage of a dispatching system as well as a predefined load-driven resource allocation strategy of computing resources,and a service-oriented deployment strategy for clients＇ resources.Though service-oriented dispatching applications and virtualization of hardware resources,an efficient and reasonable resource allocation of railway dispatching system could be attained.
