Abstract
A network controller provides proactive notification of a wireless client device's address rotation to layer 2 (L2) and/or layer 3 (L3) devices. Traditional methods of device address discovery rely on broadcasting of address queries across a plurality of links until a path to a device having the queried address responds. As device address changes become more frequent in an effort to improve user privacy, traditional methods of address discovery impose a large burden on networks, reducing their performance and efficiency. By proactively propagating address changes to upstream devices, the need for broadcast oriented address discovery techniques is reduced, resulting in improved network performance.
