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.
