    Abstract: A wireless mesh network includes mesh access points (mesh APs) and a root access point (RAP) forming a root of a tree of the mesh APs in which the mesh APs are linked back to the RAP through parent-child relationships over wireless backhaul links. A mesh AP provides access to the mesh network via connections to wireless clients in one or more wireless local area networks (WLANs) served by the mesh AP. The mesh AP stores mappings between the one or more WLANs served by the mesh AP and one or more virtual local area networks (VLANs) configured on a wired network and to which the WLANs are assigned. The mesh AP receives mappings between the VLANs configured on the wired network and WLANs served by the mesh AP as known by the RAP. If the stored mappings and the received mappings differ, the mesh AP updates the stored mappings with the received mappings that differ from the stored mappings.

    Abstract: In one embodiment, a method includes selecting at a network device, seed access points from a plurality of access points and assigning each of the seed access points to a wireless network controller. The seed access points join the assigned wireless network controllers before the remaining access points join the wireless network controllers. Each of the remaining access points is associated with one of the seed access points and joins the same wireless network controller as the seed access point. An apparatus and logic are also disclosed herein.

    Abstract: A method is performed at a mesh access point (MAP) in a wireless mesh network including access points (APs) of a spanning tree being divided among multiple Internet Protocol (IP) subnets. The method includes receiving from a first parent AP to which the MAP is a child a first IP subnet identifier indicating the first IP subnet to which the first parent AP belongs. The method also includes obtaining a first IP address associated with the first IP subnet, roaming from the first to a second parent AP, receiving from the second parent AP a second IP subnet identifier indicating a second IP subnet to which the second parent AP belongs, determining if the first and second parent APs are both part of the same IP subnet, and determining whether to maintain connectivity with a current controller or establish connectivity to a new controller based on results of the determining.

    Abstract: Access points and a wireless client device, such as a workgroup bridge, are configured to optimize a roaming algorithm of the client device for a high-speed vehicle scenario, such as a high-speed train. A static/dynamic neighbor list is generated and used to improve scanning efficiency. An improved parent access point selection procedure, metrics, and thresholds are provided to optimize client roaming along the vehicle's path, e.g., the train track.

    Abstract: In one embodiment, a method implemented on a computing device includes: selecting a wireless access point (AP) to process from among a deployment of wireless access points (APs), defining a neighborhood based on the AP and neighboring APs, where the neighboring APs are within a one-hop radius of the AP, calculating a client distribution optimal received signal strength indicator (RSSI), where the client distribution optimal RSSI (CD optimal) is a minimum receiver start of packet detection threshold (RX-SOP) setting for maintaining existing client device coverage by the AP, calculating a neighbor relations optimal RSSI threshold (NR optimal), where the NR optimal is a function of at least a transmit power control threshold (TPC) for maintaining visibility between the AP and the neighboring APs, calculating an RX-SOP setting for the AP as a function of CD optimal and NR optimal, and applying the RX-SOP setting to the AP.

    Abstract: A first wireless device (e.g., an access point) receives a message from a second wireless device (e.g., a client device). The first device determines an angle-of-arrival of the message at a plurality of antennas of the first wireless device. The first device compares the angle-of-arrival with an angle-of-arrival threshold to determine whether to transmit a response message to the second wireless device. In one example, the first wireless device is a wireless access point device operating in a wireless network, the second wireless device is a wireless client device operating in the wireless network, the message is a probe request message and the response message is a probe response message.
