Abstract: In one embodiment, a transmitting node may be configured to transmit a wireless advertisement frame over a computer network, wherein the frame includes a source address of a reachable node being advertised, a destination address to which the reachable node is to be advertised, a transmitter address of the transmitting node, and a receiver address of a wireless access point to which the wireless advertisement frame is to be received. Also, the wireless access point may be configured to receive the wireless advertisement frame from the network, and in response, transmit a reflected wireless advertisement frame having the source address of the reachable node, the destination address to which the reachable node is to be advertised, a transmitter address of the access point, and a receiver address that indicates the reflected frame is to be accepted by any appropriate receiver excluding the transmitting node.

Abstract: A controller controls access points (APs) in a network of APs. The controller causes the first AP to establish an Internet Protocol (IP) tunnel with a router connected with a wired network and over which data packets are routed between the wired network and a client device wirelessly connected to the first AP. The controller receives a roam indication that the client device is wirelessly connected with a second AP. In response to the indication, the controller instructs the first AP to maintain the IP tunnel with the router and instructs the second AP to establish an inter-AP tunnel with the first AP in order to route traffic between the wired network and the client device over both the IP tunnel and the inter-AP tunnel.
