Packet sending method and related device

A packet sending device, comprising:

• a processor;
• and
• a memory coupled to the processor and storing instructions that, when executed by the processor, cause the packet sending device to be configured to:
• when a multipath connection meets a first condition for disabling a small packet sending control policy of the multipath connection, disable the small packet sending control policy, wherein the small packet sending control policy controls a time interval at which the packet sending device sends a plurality of first small packets using the multipath connection, and wherein a length of data comprised in the first small packet is less than a maximum segment size (MSS);
• and
• send second small packets on a plurality of paths of the multipath connection in a redundant transmission mode after disabling the small packet sending control policy, wherein a length of data comprised in the second small packets is less than the MSS,
• wherein the first condition indicates that one of the first small packets is sent using a redundant scheduling policy or that one of the first small packets is to be repeatedly sent on another path of the multipath connection after being sent on one path of the multipath connection, and
• wherein the redundant scheduling policy instructs the sender to transmit data in the redundant transmission mode.

A computer program product comprising computer-executable instructions for storage on a non-transitory computer-readable medium that, when executed by a processor, cause a computer to:

• when the multipath connection meets a first condition for disabling a small packet sending control policy of the multipath connection, disable the small packet sending control policy, wherein the small packet sending control policy controls a time interval at which the sender sends a plurality of first small packets using the multipath connection, and wherein a length of data comprised in the first small packets is less than a maximum segment size (MSS);
• and
• send second small packets on a plurality of paths of the multipath connection in a redundant transmission mode after disabling the small packet sending control policy, wherein a length of data comprised in the second small packets is less than the MSS,
• wherein the first condition indicates that one of the first small packets is sent using a redundant scheduling policy or that one of the first small packets is to be repeatedly sent on another path of the multipath connection after being sent on one path of the multipath connection, and
• wherein the redundant scheduling policy instructs the sender to transmit data in the redundant transmission mode.
