Abstract: The present disclosure provides a technical scheme for transmitting video streams in WiFi mesh networks, including a method for transmitting multicast video in an access points in a WiFi mesh network, wherein the method includes: receiving a video stream and determining the node(s) to which the video stream needs to be transmitted, wherein the video stream includes a multicast address; determining dynamically a transmission mode of the video stream and transmitting corresponding video stream to multiple stations using the transmission mode when the nodes are the multiple stations corresponding to the multicast address; transmitting corresponding video stream to a next access point using unicast mode when the node is the next access point.

Abstract: In one embodiment, the method includes if a first network device having a first path with a second network device determines that a terminal device is to be handed over from the second network device to a third network device, establishing a second path between the first and third network devices; disabling data transmission for the terminal device via the first path; transmitting a handover indication to the second network device to cause it to suspend transmission of buffered data to the terminal device and to transmit remaining data to the third network device; and upon receiving a completion indication from the second network device that transmission of the remaining data is complete, enabling data transmission for the terminal device via the second path.
