  • Publication number: 20190289670
    Abstract: Example implementations relate to multicast multi-user grouping. For example, an apparatus may comprise a processing resource that may rank a plurality of stations associated with the apparatus based on a characteristic associated with a first multicast group containing a first set of stations among the plurality of stations, and a characteristic associated with a second multicast group containing a second set of stations among the plurality of stations. The processing resource may assign a first group of stations from the first multicast group and the second multicast group to a first multi-user group and assign a second group of stations from the first multicast group and the second multicast group to a second multi-user group. The processing resource may convert a multicast frame associated with a station from the first multi-user group to a unicast frame, and transmit the unicast frame to each station in the first multi-user group.

  • Patent number: 10382564
    Abstract: The present disclosure discloses a method and a network device for client association management based on estimated session duration. Specifically, a network device determines that a client device is on an active session. The client device is associated with a first access point of a plurality of access points. The network then estimates a remaining duration of the active session to obtain an estimated remaining duration. Responsive at least to the estimated remaining duration of the active session being greater than a threshold value, the network device causes the client device to associate with a second access point different than the first access point. Responsive at least to the estimated remaining duration of the active session being less than the threshold value, the network device refrains from causing the client device to associate with the second access point.
