Abstract: A network transmission method comprises determining at least one network status parameter of the subflows. When at least one network status parameter of at least two of the plurality of subflows satisfies a preset condition, the method further comprises performing aggregated transmission for the data using the at least two subflows, wherein the aggregated transmission means that one data packet is sent using only one of the at least two subflows, and data packets sent using all of the at least two subflows are different from each other.

Abstract: This application provides a subflow establishment method. A local-end device obtains an identifier of an operator currently accessed by a network interface card of the local end device. The local-end device obtains a plurality of IP addresses of a peer-end device and identifiers of operators to which the plurality of IP addresses are homed; and establishes, by matching a plurality of operators corresponding to the local-end device and the plurality of operators corresponding to the peer-end device, a subflow between an IP address pair homed to a same operator. In this way, the established subflow does not cross operators as far as possible. This reduces negative impact of cross-operator communication of some subflows on transmission performance of a multipath connection, thereby better leveraging an advantage of the multipath connection in transmission performance in comparison with a single-path connection.

Abstract: A packet sending method includes determining, that a multipath connection meets a first condition, where the first condition is used to disable a small packet sending control policy used for the multipath connection, the small packet sending control policy is used to control a time interval at which the sender sends small packets using the multipath connection, and a length of data included in the small packet is less than a maximum segment size (MSS), disabling, by the sender, the small packet sending control policy, and sending, by the sender, a plurality of small packets on a plurality of paths of the multipath connection in a redundant transmission mode after disabling the small packet sending control policy.

Abstract: This application provides example data transmission methods and corresponding example devices. One example method includes sending, by a first device, a first packet to a second device, where the first packet includes transmission policy negotiation information, and where the transmission policy negotiation information is used to negotiate a transmission policy used when the second device uses a multipath connection. The first device can then receive a second packet from the second device, where the second packet includes first policy information, and where the first policy information indicates a transmission policy used when the second device uses the multipath connection. The first device can then transmit data with the second device based on the first policy information by using a transmission policy corresponding to the first policy information.
