Abstract: In one embodiment, a method includes selecting at a network device, seed access points from a plurality of access points and assigning each of the seed access points to a wireless network controller. The seed access points join the assigned wireless network controllers before the remaining access points join the wireless network controllers. Each of the remaining access points is associated with one of the seed access points and joins the same wireless network controller as the seed access point. An apparatus and logic are also disclosed herein.

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.

Abstract: Techniques are presented herein to provide human mobility pattern based modeling and tracking of a group of network enabled user devices associated with the same person. An association is made, at a tracking device, between a plurality of user devices and a user. Location information for each of the plurality of user devices is derived through network activity of the plurality of user devices. Locations for the plurality of user devices are derived from the location information. One or more predetermined user mobility pattern rules are applied to the plurality of user devices. User anomalies are detected when the tracked locations indicate that one or more of the plurality of user devices has violated one or more the predetermined user mobility rules.
