Abstract: A node within a wireless mesh network is configured to select a primary path through an access point and to designate that access point as the primary access point for the node. The access point then transmits a failover message indicating that the node designated that access point as the primary access point for the node at a particular time. When another access point receives the failover message, the other access point may determine that the first node has also designated the other access point as the primary access point for the node, and may then de-register the node and stop advertising a primary path to the node.

Abstract translation: 无线网状网络中的节点被配置为选择通过接入点的主路径，并将该接入点指定为该节点的主接入点。 然后，接入点发送指示该特定时刻指定该接入点作为节点的主接入点的节点的故障切换消息。 当另一个接入点接收到故障转移消息时，另一个接入点可以确定第一节点还指定了另一个接入点作为该节点的主接入点，​​然后可以对该节点进行取消注册并停止向主要路由发布广告 节点。
