Abstract

The transmission uses a so called sliding window method wherein an emitter (4) is authorised to transmit several data packets contained in a window to a receiver (2), prior to reception of an acknowledgement for at least one of said packets and to provide the window in order to emit the following packets gradually as far as the acknowledgement thereof is received. The emitter (4) measures the time for a corresponding loop between the transmission of a data packet and the reception of the acknowledgement thereof at successive sampling instants (ti) and monitors the state of a (RTT) loop time. Every time, when it detects a stable state thereof (RTTn) it records the pair of values (RTTn, Wn,max) containing the stable value of the (RTTn) loop time and the maximum size of the detected emitting window for said stable value of the (RTTn) loop time.
