The application discloses a method, system, control device and node device for data transmission. The method includes determining a source node for data transmission; selecting a node which has not been selected for reception of the data as a destination node for the data transmission, from a list of nodes for the reception of the data, wherein the destination node serves as the next nearest node of the source node; wherein the list of nodes comprises at least one identifier and an address of each node; and issuing a data transmission task to the source node, wherein the data transmission task comprises the identifier and the address of the destination node, so that the source node transmits the data to the destination node according to the address of the destination node. The technical solutions of the application can guarantee the data transmission speed and the data transmission efficiency.
