    Abstract: A gateway device receives interface information sent by an interface extension device, where an Ethernet interface of the interface extension device is connected to a target Ethernet interface of the gateway device, and the interface information includes an interface type and a media access control (MAC) address of a first non-Ethernet interface of the interface extension device. The gateway device creates a first virtual interface on the target Ethernet interface based on the interface information, where the first virtual interface corresponds to the first non-Ethernet interface, and an interface type of the first virtual interface is an Ethernet interface. The gateway device sends an interface creation success notification to the interface extension device. The gateway device may obtain data of the first non-Ethernet interface through the first virtual interface, thereby implementing interface extension of the gateway device.

    Abstract: A packet sending method includes: receiving, by a first node, a first broadcast data packet sent by a second node; and if a sequence number of the first broadcast data packet equals 1 plus a sequence number of a latest data packet saved by the first node, and the first node does not receive, within a first preset time period, a first acknowledgement indication for the first broadcast data packet of the second node, sending, by the first node, a first broadcast acknowledgement packet when the first preset time period elapses, where the first broadcast acknowledgement packet includes the first acknowledgement indication, and the first acknowledgement indication includes the sequence number of the first broadcast data packet and an address of the second node. This method could resolve acknowledgement packet implosion while ensuring broadcast packet reliability of a wireless mesh network.
