The aim of the invention is to achieve a good utilization of the capacity of a transmission channel while ensuring guaranteed bandwidths for traffic flows transmitted over the transmission channel. To this end, the invention provides a method for transmitting traffic flows ( 1, 2, 3 ) over a common transmission channel ( 7 ) whose ( 1, 2, 3 ) data (A E) arrives in at least one buffer ( 4, 5, 6 ) connected upstream from the transmission channel ( 7 ). According to this method: a guaranteed bandwidth (BG 1 ) is determined for the transmission of packets (A E) of each traffic flow ( 1 ) over the transmission channel ( 7 ); a maximum bandwidth (B 1 Max) is determined fur the transmission of packets (A E) of each traffic flow ( 1 ) over the transmission channel ( 7 ), whereby packets (D E) of a traffic flow ( 1 ), which arrive in a buffer ( 4 ) with a transmission rate less than the guaranteed bandwidth (BG 1 ), are chronologically transmitted over the channel ( 7 ) before the packets (ABC) of this traffic flow that arrive in buffer ( 4 ) with a transmission rate exceeding the guaranteed bandwidth (yellow, red), and; packets (ABC) of a traffic flow, which arrive in a buffer ( 4 ) with a transmission rate lower than the maximum bandwidth (B 1 Max), are chronologically transmitted over the transmission channel ( 7 ) before packets (C) of the traffic flow ( 1 ) that have arrived in the buffer ( 4 ) with a transmission rate exceeding the maximum bandwidth (B 1 Max) of the traffic channel in the transmission channel ( 7 ) (red).
