1. A method comprising:
accepting, by an Access Point (AP) Multi-Link Device (MLD), an association with an MLD client, wherein at least a first link and a second link are established between the AP MLD and the MLD client, the first link is an active link over which the MLD client transmits and receives data to and from the AP MLD;
collecting a first set of traffic load data associated with the first and second links;
transmitting a Basic Service Set (BSS) load report to the MLD client, the BSS load report including a traffic load on the second link obtained from the first set of traffic load data, the second link being less loaded than the first link;
collecting a second set of traffic load data associated with the first and second links;
based on the first and second set of traffic load data, detecting an active link alternation from the first link to the second link by the MLD client responsive to the MLD client receiving the BSS load report; and
mitigating future active link alternation through BSS load report management.
