12 Backhaul optimization
In a Multi-AP network, the backhaul STA of a Multi-AP Agent connects to a BSS to access backhaul connectivity. A Multi-AP Agent might have chosen from multiple candidate BSSs during onboarding and subsequently a Multi-AP Controller might want to move that Multi-AP Agent to a different BSS.
在Multi-AP网络中,Multi-AP代理的Backhaul STA连接到BSS以访问Backhaul连接。Multi-AP代理可能在入站期间从多个候选BSS中选择,随后Multi-AP控制器可能希望将该Multi-AP代理移动到不同的BSS。(一个Backhaul STA开始连接时,随机从一个Backhaul AP中选一个,后续控制器会根据算法,让此代理连接到一个特定的Backhaul AP,以达到速率最优)
If triggered, a Multi-AP Controller shall send a Backhaul Steering Request message to request the Multi-AP Agent to connect its backhaul STA to a different BSS per section 17.1.29.
如果触发,Multi-AP控制器应根据第17.1.29节发送Backhaul steering请求消息,请求Multi-AP代理将其Backhaul STA连接到列外一个BSS(AP)上。
If a Multi-AP Agent receives a Backhaul Steering Request message, then it shall respond within one second with a 1905 Ack message to the Multi-AP Controller and attempt to (re-)associate with the target BSS specified in the message. After the Multi-AP Agent has associated with the target BSS successfully or 10 seconds has expired since the reception of the Backhaul Steering Request message, the Multi-AP Agent shall send a Backhaul Steering Response message to the Multi-AP Controller per section 17.1.30. If the Multi-AP Agent succe
