Abstract
Techniques are provided for delivering data to a wireless client device in a wireless local area network via a plurality of access point devices as the wireless client device roams from one access point device to another. A wireless client device receives data communications (i.e., traffic) via a first wireless access point device in the wireless local area network. An impending roam of a wireless client device is detected. A set of one or more candidate wireless access point devices other than the first wireless access point device is determined to which the wireless client device may potentially roam. The one or more wireless access point devices in the set are assigned to a multicast group, and the traffic is sent to the multicast group.
