1. A cloud controller configured to control a wireless network having a plurality of access points controlled by an edge controller, the cloud controller comprising:
a network interface configured to communicate with the wireless network;
a memory; and
a processor coupled to the memory and the network interface, wherein the processor is further configured to:
receive performance metrics for the wireless network including congestion information;
compare the congestion information with congestion criteria;
identify clients connected to the wireless network as candidates to be transferred to another access point in the wireless network;
send a steering command to the edge controller with a list of identified clients to steer based on the identified clients; and
receive an indication of clients steered by the edge controller,
wherein identifying clients connected to the wireless network as candidates to be transferred further is based upon at least one of:
the clients being dual band capable;
steering attempt success rate;
a ranking of clients current usage throughput rates; and
a limit on the number of clients that may be steered using one steering command.
