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, said method comprising the following steps:
- for each destination node, the determining (E6) of a first set of source nodes from which there exist disjointed paths, in said communications network, to reach said destination node;
- the determining (E12) of a second set of source nodes which is the intersection of the first determined sets for said destination nodes;
- determining (E13) a sub-network for implementing the network coding comprising:
o source nodes which belong only to the second set of source nodes,
o the plurality of destination nodes, and
o nodes included in the disjointed paths connecting the source nodes of said second set of source nodes and said destination nodes; and
- building (E20) a network coding scheme based on said determined sub-network. |
