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.
