n nodes 20 1 , 20 2 ,... 20 n , a recording command device 10 for instructing and controlling the recording of data to each node, and a transmission command device 30 for reading the data recorded at each node, each of which is connected via a network In the type storage system, the write command device 10 performs FEC encoding at a code rate of q / p on data consisting of p blocks to make the data having q blocks, and the recording probability recorded by the node in this data. ? is added and sent out over the network. At the time of reading, the transmission command apparatus 30 returns the data to which the reply probability beta which returns data is added. |
