1. Method for transmitting data of a stream to be stimulated, the stream to be stimulated coming from a sender device and intended for a receiver device through a network segment included in a communications network and according to a packet transport protocol with acknowledgement, each packet being associated with a sequence number, wherein said method comprises the following steps implemented by an input device of said network segment for said stream to be stimulated:

  • determining a starting packet associated with a sequence number higher than the sequence numbers of packets in transit, packets in transit being packets transmitted by said input device via the network segment but for which the input device has not yet received a positive acknowledgement message coming from the receiver device;

    selecting, as a function of a consumption of a target bandwidth for the transmission of said stream, packets of said stream following said starting packet;

    upon reception of a positive acknowledgement message of said starting packet coming from the receiver device, launching a temporary phase with a duration that depends on the number of selected packets, comprising a step of transmitting to the sender device an anticipated positive acknowledgement message for said starting packet and for each selected packet;

    discarding the positive acknowledgements received from the receiver device which correspond to said selected packets and for which an anticipated positive acknowledgement message has been transmitted.
