平台体系结构上采用三层结构整个系统分为用户层,服务层和子系统层,每层功能相对独立设计,层与层之间采用标准方式联系。这种设计的最大好处在于每层功能的改变不会影响其它层次和平台的主干核心。●用户层采用基于Internet的管理,除了 The platform architecture uses a three-tier structure The entire system is divided into user layer, service layer and subsystem layer, each layer is relatively independent of the design function, the layer and the layer between the standard way. The biggest benefit of this design is that changes in the function of each layer will not affect the backbone of other layers and platforms. ● User layer uses Internet-based management, except
