Abstract:
A method for managing allocation of paths for transmission, in packets of symbols, of at least a first data content, each content being transmitted from a source node up to a destination node in a meshed communications network comprising a plurality of nodes, each destination node receiving a plurality of copies of a same packet of symbols of the content transmitted to said destination node by a source node, each copy being received by the destination node via a distinct transmission path directly from the source node or via at least one relay node of the meshed communications network, the packets being encoded with an error correction code enabling decoding by erasure of packets symbols. Such a method comprises the following steps: selecting a set of transmission paths from the source node up to the destination node for the transmission of copies of at least one packet of the first content, for which an estimated first number of erasures of symbols of the at least one packet is smaller than a determined threshold, the first number of erasures being estimated from a piece of information on quality of transmission that is determined and associated with each of the selected transmission paths, the threshold being determined as a function of an erasure correction capability of the error correction code; allocating the selected transmission paths to the transmission of the first content from said source node up to said destination node.
