Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of dual-channel backhaul in mesh network. The method comprises: generating, at a first device, a first transmit queue comprising a plurality of data packets to be transmitted to a second device on a first backhaul link; in accordance with a determination that a distribution strategy is met, distributing at least one data packet from the plurality of data packets; generating a second transmit queue comprising the at least one data packet, the second transmit queue to be transmitted to the second device on a second backhaul link different from the first backhaul link; and transmitting, to the second device, the plurality of data packets except for the at least one data packet on the first backhaul link and the at least one data packet on the second backhaul link. By such a dual-channel backhaul architecture, the channel resources on the two channels can be fully utilized for backhaul. With the distribution strategy and the numbering scheme, the solution proposed in the present disclosure bypasses part of the data packets from one backhaul link to another one before the air interface resources on the one backhaul link is run out, without discarding the backhaul data. As such, the throughput of the entire mesh network can be significantly improved and the system is more stable.
