Abstract: In the context of a transmission of data for a multipath communication from source terminal equipment to destination terminal equipment, the method: establishes, on at least one multipath communication path, a plurality of connections with the destination terminal equipment; for each path on which a said plurality of connections was established, selecting to make it active at least one connection among the plurality of established connections, the other established connections being put in reserve; distributing the data between the selected connections, referred to as active connections, in accordance with at least one predefined distribution rule, and transmitting the distributed data. Upon detecting a transmission incident via an active connection on a path on which a said plurality of connections was established, the method closes said active connection, and makes active a connection that had been put in reserve on said path.
