• Guide the steering procedure according to 802.11v protocol.

Backhaul Steering

• Check network environment through periodically link metric frames exchange.
• Decide best-bss for Agent AP based on path score and distance.
• Query steer by sending frame from controller AP, and acknowledge the end of steer by agent AP.
