| 摘要 |
Embodiments of the present invention disclose a multilink-based data transmission method, and the method includes: establishing separately, by a first device, first tunnels in multiple different types of links in which the first device and the second device have established a communication connection; establishing, by the first device, a second tunnel that crosses the first tunnels established in the multiple different types of links; analyzing, by the first device, a load state of each first tunnel crossed by the second tunnel, and selecting a first tunnel used to transmit a target packet; and encapsulating, by the first device, the target packet into the second tunnel, and sending, to the second device, through the first tunnel used to transmit the target packet, the packet encapsulated into the second tunnel. Correspondingly, the embodiments of the present invention further provide a data transmission device. In the embodiments of the present invention, a utilization rate of links supported by a network device can be improved. |
