A method is proposed for building a network coding scheme adapted to the transmission of data between a plurality of source nodes and a plurality of destination nodes in a communications network comprising a plurality of nodes, the method comprising the following steps: for each destination node, determining a first set of source nodes from which there exist disjointed paths, in the communications network, to reach the destination node; determining a second set of source nodes which is the intersection of the first determined sets for the destination nodes; determining a sub-network for implementing the network coding comprising: source nodes which belong only to the second set of source nodes, the plurality of destination nodes, and nodes included in the disjointed paths connecting the source nodes of the second set of source nodes and the destination nodes; and building a network coding scheme based on the determined sub-network.
