Distributed storage system, the storage node, data providing method and program

It generated time data from each of the plurality of storage nodes for storing and distributing the stream data sent from the device to be able to get close enough data elements. A plurality of storage nodes in the distributed storage system includes a data storage unit for storing the stream data output from the device, and generates a synchronized time frame with the other storage nodes, stored in the data storage unit a first time frame generator associating a data element to one of the time frame included in the stream data, based on the access request from the client terminal, a predetermined time from the stored stream data in the data storage unit It has a data selector for selecting data elements associated with the frame, and a data transmission unit for transmitting the data element selected by the data selection unit to the client terminal.
