    • The invention relates to the field of multi-path communication. More particularly the invention deals with a method for evaluating an available bitrate (BR1 1 ) over a path (P1) among one of at least two paths (P1, P2, P3) linking a first endpoint (1) and a second endpoint (2), said path (P1) being called an evaluation path, said first endpoint (1) being configured for sending data packets to said second endpoint (2), said second endpoint (2) being configured for sending at each data packet reception an acknowledgment message to said first endpoint (1) through one of the at least two path (P1, P2, P3) selected at each data packet reception. According to the invention, at the first endpoint (1), steps of: - inserting a flag (A) in a first data packet (DP1) out of said data packets to be transmitted to said second endpoint (2) through the evaluation path (P1); - sending said first data packet (DP1) through the evaluation path (P1); - measuring and recording a sending time (t1) of the first data packet (DP1) from said first endpoint (1); - receiving an acknowledgment message (Ack) sent by said second endpoint (2) through said evaluation path (P1) for acknowledging reception of said first data packet (DP1) at said second endpoint (2); - measuring and recording an arrival time (t2) of said acknowledgment message (Ack) at said first endpoint (1); - assessing the available bitrate (BR1 1 ) from an interval between the sending time (t1) and the arrival time (t2) and from the size of said first data packet (DP1).
