Abstract: Embodiments of the present invention provide a method for learning a media access control address, a network device and a system. The method includes: generating a key value according to a key field of a received packet, and obtaining an index value corresponding to the key value according to the key value; performing a linear random iteration on the index value according to a preset number of iterations; searching, according to an iteration index value obtained during a first iteration, in a MAC address pool for a MAC address corresponding to the iteration index value obtained during the first iteration; and learning a MAC address of the packet according to a search result. By using the embodiments of the present invention a media access control address space may be fully utilized, and the problem of media access control address conflicts may be solved to the greatest extent.

Abstract: Embodiments of the application provide a data transmission method and a device. A sending device periodically obtains a first packet sequence number and a second packet sequence number. The first packet sequence number is a maximum value in packet sequence numbers respectively corresponding to packets that belong to a first data flow and that are received by a receiving device through a first data channel in a statistics period. The second packet sequence number is a maximum value in packet sequence numbers respectively corresponding to packets that belong to the first data flow and that are received by the receiving device through a second data channel in the statistics period. The sending device updates a packet cache queue of: the first data channel, the second data channel, or both the first and the second data channels, based on the first packet sequence number and the second packet sequence number.
