Abstract
A method provides for building a network coding scheme for the transmission of data between multiple source nodes and multiple destination nodes in a communications network having multiple nodes. The method includes the steps of: 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; and determining a sub-network for implementing the network coding. The sub-network includes source nodes which belong only to the second set of source nodes, the multiple destination nodes, and nodes included in the disjointed paths connecting the source nodes of the second set of source nodes and the destination nodes. The method also includes the step of building a network coding scheme based on the determined sub-network.
