摘要

A distributed storage system having n nodes (201), (202), . . . , (20n), a recording commanding device (10) for commanding recording of data in each node, and a transmission commanding device (30) for reading out the data recorded in the respective nodes. These nodes and the devices are interconnected over a network. The recording commanding device (10) applies FEC coding, with the coding rate of q/p, to data composed of p blocks, to generate q blocks, and appends a recording probability a, recorded by the node, to the data, to send out the resulting data to the network. In readout, the transmission commanding device (30) responds data to which has been appended the response probability β in responding the data.
