【摘要】 随着大数据的应用推进,大数据中心逐渐成为新型智慧城市建设的一个热点。但是,当前业界对于智慧城市大数据中心的架构尚未形成统一意见。从智慧城市大数据中心的三大职能入手,对其功能进行分析,包括数据服务功能和智慧城市应用功能,并提出了一种智慧城市大数据中心的分层架构。该架构由大数据基础设施层、大数据服务层、大数据应用层、应用服务网关与支撑保障分系统构成,并对各层或分系统的功能与组成进行了说明。更多还原

【Abstract】 With the promotion of big-data application, the big-data center becomes a focus in the constructions of new smart cities. However, the unified view on the architecture of big data centers in smart cities is not formed yet in industrial community. From the three major duties, the functions of big-data centers in smart cities are analyzed, involving data service functions and smart city application functions. And a layered architecture of big-data centers, composed of big-data infrastructure layer, big-data service layer, big-data application layer, application & service gateway and OAM subsystem, is proposed. The functions and organization of each layer or subsystem are also explained in detail.更多还原
