A data packet processing method, a terminal, and a gateway, where the terminal, determines to transmit network traffic using a first network and a second network simultaneously based on an aggregation flow table, and upon that determination, the terminal sends a quantity of first uplink data packets to the gateway using a first network interface card corresponding to the first network, and sends a quantity of second uplink data packets belonging to the same Transmission Control Protocol (TCP) connection as the first uplink data packets to the gateway using a second network interface card corresponding to the second network, where a source Internet Protocol (IP) address carried in each of the first uplink data packets is the IP address of the first network interface card, and a source IP address carried in each of the second uplink data packets is the IP address of the second network interface card.

Data packet processing method, network traffic management method, apparatus, and system

A data packet processing method includes acquiring, by a terminal, an aggregation flow table, where the aggregation flow table includes a management policy for managing network traffic of a first network and network traffic of a second network, determining, by the terminal, according to the aggregation flow table, a transmission network used for transmitting a first uplink data packet, and when the terminal determines to transmit the first uplink data packet using the first network, sending the first uplink data packet to the first network using a first network interface card, and forwarding the first uplink data packet to a gateway, and when the terminal determines to transmit the first uplink data packet using the second network, sending, by the terminal, the first uplink data packet to the second network using a second network interface card, and forwarding the first uplink data packet to a gateway.

Embodiments of the present invention disclose a data transmission method and apparatus for a terminal. The terminal exchanges data of an application with a server through a first port by using a first access node; when one port in a second port set is in an enabled state, the terminal accesses one access node in a candidate access node set through the enabled port in the second port set, and exchanges, based on the Multipath TCP, the data of the application with the server by using an access node corresponding to the enabled port.
