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.

Abstract: This application describes a frame aggregation method. A first forwarding node device receives a first data frame and a second data frame, where the first data frame includes a first MAC header and a first MSDU, the second data frame includes a second MAC header and a second MSDU, and a destination MAC address in the first MAC header is the same as a destination MAC address in the second MAC header; and generates a first aggregated frame, where the first aggregated frame includes an aggregated MAC header and an aggregated MSDU, the aggregated MSDU includes a first sub-MSDU and a second sub-MSDU, the first sub-MSDU includes the first MSDU and a source MAC address of the first data frame, and the second sub-MSDU includes the second MSDU and a source MAC address of the second data frame. A second forwarding node device sends the first aggregated frame.

Abstract: This application discloses a network resource scheduling method and an apparatus. A specific scheduling process includes: receiving, by a first network node, a message, where the message includes a network resource that needs to be scheduled between a plurality of network nodes on a multi-hop path; and after resource scheduling is performed between the first network node and a second network node, sending the message to the second network node, to trigger network resource scheduling between the second network node and a third network node. Therefore, end-to-end resource scheduling is implemented by using one message, and end-to-end resource reservation on the multi-hop path can be implemented.
