Abstract: A method for load balancing traffic from controller to destination access point (AP) via switch across multiple physical ports starts with controller receiving a packet from a source client device that is destined for destination client device associated with destination AP. The controller may select, based on an identifier associated with source or destination client device, a first or a second controller IP address. Controller may encapsulate the packet to generate an encapsulated packet including an outer header that includes the selected controller IP address. Controller may transmit the encapsulated packet to the switch that may distribute traffic to destination AP across multiple physical ports based on the selected controller IP address. Controller may also select a destination port based on destination client device of a packet and may encapsulate the packet using CAPWAP to generate an encapsulated packet including the destination port in a header of the encapsulated packet.

Abstract: Location detection of a mobile device is achieved by initiating an API call at an application program. The API call directs an operating system of the mobile device to initiate a scan of wireless access points within wireless communication range of the mobile device. The scanning performed by the mobile device is detected by the network via one or more of the wireless access points. A location of the mobile device is estimated by the network based on detection of the mobile device via the one or more wireless access points. Location-based services are provided to the mobile device by the network based on the estimated location of the mobile device. The location-based services may be transmitted to the mobile device via a different wireless access point and/or wireless communication protocol than used during scanning and/or detection of the mobile device.
