Abstract: A packet transmission method includes: receiving packets on a plurality of subflow connections of a multipath transmission control protocol (MPTCP) connection, and determining, based on the received packets, that packets at an MPTCP layer are out of order; determining that a blocking packet causing out-of-order is not received within a tolerance time, where the tolerance time is less than a largest RTO in RTOs of the plurality of subflow connections; and sending, by the network component, a retransmission instruction packet of the blocking packet on a target subflow connection in the plurality of subflow connections, where the retransmission instruction packet is used to instruct a sending device of the blocking packet to retransmit the blocking packet. Thus, there is no need to trigger retransmission after a subflow RTO expires, thereby shortening a delay.

Abstract: A packet processing method and system, and a network device are disclosed, and belong to the field of network technologies. A first network device sends a first packet to a second network device through a first tunnel, and sends a second packet to a third network device through a second tunnel. The second network device forwards the first packet to the third network device through a third tunnel. The third network device processes the first packet and the second packet. The first network device is located at a first site. The second network device and the third network device are located at a second site. The first site and the second site are connected through a wide area network. Wide area network multipath transmission may be implemented in a multi-gateway scenario.
