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