The invention relates to a method of controlling errors in the transmission of packets transmitted over at least one transmission link between a transmitter and a receiver, the said transmitter receiving from an input multiplex packets belonging to a plurality of end to end associations or groups of end to end associations and transmitting them in the form of sequences of packets over a or the said transmission line, the said receiver, on reception of a packet, verifying whether it is correctly received and if so, delivering it to an output multiplex, and if not, sending to the said transmitter a negative acknowledgement so that the transmitter can re-transmit it. This method is characterised in that it consists, at the transmitter side, of allocating, to each packet to be transmitted over the or a transmission line, two indices, one giving the sequence number of the said packet and the other enabling said packet to point to the last packet which was previously transmitted belonging to the same end to end association or the same group of associations as the said packet, and, at the receiver side, in determining, on a correct reception of a packet, the packet pointed to by the said received packet, and, if this packet pointed to has been delivered to the output multiplex, then delivering the said received packet, otherwise not delivering it.
