The method includes receiving , by a first device , an acknowledgement packet that is from a second device and that includes an ECE identifier . Based on an indication of the ECE identifier the first device starts monitoring a plurality of sub streams on a plurality of transmission paths between the first device and the second device , and grouping , into one set , sub streams that meet a congestion control condition . Additionally , intra set congestion control is performed on the sub streams in the set . Separately congestion control is performed on a sub stream that is not in the set . The congestion control method is applied to a scenario in which data transmission is performed between the first device and the second device by using the MPTCP . 6 Claims , 9 Drawing Sheets Routing device 12 000 000 000 Transmit end 10 Receive end 11
