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.
