Abstract: Examples relate to radio health monitoring. One example relates to a system for radio health monitoring. They system may comprise a physical processor implementing machine readable instructions stored on a non-transitory machine-readable storage medium that cause the system to determine whether a radio in a wireless network has high utilization, responsive to determining that the radio has high utilization, determine a root cause for the high utilization, and provide an alert comprising information about the radio, the high utilization, and the determined root cause.

Abstract: Establishing peer-to-peer tunnels between clients in a mobility domain. In normal operation, clients attached to a network having access nodes connected to a central controller transfer all traffic through the central controller. This traffic is passed using tunnels between the access node and the central controller. Tunnels may be encrypted, and GRE tunnels may be used. A mobility manager operating in the controller tracks access nodes connected to the controller, and clients connected to those access nodes. When the mobility controller recognizes traffic passing between clients in its mobility domain that is eligible for peer-to-peer forwarding, it instructs the access nodes supporting the clients to establish a peer-to-peer tunnel between the nodes, and direct the client traffic through this peer-to-peer tunnel. The peer-to-peer tunnel may be session based, or may be aged.

Abstract: Balancing client load on an access point in a wireless digital network. An access point tracks the number of connected users and accepts new connections only if the number of connected users is below a preset threshold. The number of connected users may be tracked on an access point wide basis, a per-band basis, a per-BSSID basis, or a combination. Similarly, accepting new connections may be done on an access point wide basis, a per-band basis, a per-BSSID basis, on the basis of client 802.11 capabilities, or a combination.

Abstract: Initiating peer-to-peer tunnels between clients in a mobility domain. Client traffic in a mobility domain normally passes from the initiating client to an access node, and from the access node through a tunnel to a controller, and then through another tunnel from the controller to the destination access node, and the destination client. When initiated by the controller, the access nodes establish a peer-to-peer tunnel for suitable client traffic, bypassing the “slow” tunnels through the controller with a “fast” peer-to-peer tunnel. Traffic through this “fast” tunnel may be initiated once the tunnel is established, or traffic for the “fast” tunnel may be queued up until traffic has completed passing through the “slow” tunnel.

Abstract: One of the embodiments is directed to establishing peer-to-peer tunnels between clients in a mobility domain. Normally, clients attached to a network having access nodes connected to a central controller transfer all traffic through the central controller via tunnels between the access node and the central controller. A mobility manager operating in the controller tracks access nodes connected to the controller, and clients connected to those access nodes. When the mobility controller recognizes traffic passing between clients in its mobility domain that is eligible for peer-to-peer forwarding, it instructs the access nodes supporting the clients to establish a peer-to-peer tunnel between the nodes, and direct the client traffic through this peer-to-peer tunnel. The peer-to-peer tunnel may be session based, or may be aged. Eligibility of traffic for peer-to-peer tunnels may be controlled by rules, such as limiting peer-to-peer tunnels by source or destination, by port or protocol, and the like.

Abstract: A wireless network is adapted with a wireless network switch in communication with a plurality of access points, which are in communication with one or more stations. Specifically, a network device may receive a plurality of request messages on a plurality of wireless communication channels through a plurality of access points. The request messages are originated from a single station. Furthermore, the network can extract a plurality of channel identifiers from the request messages, and generates a filtered radio frequency neighborhood list dynamically based on the extracted channel identifiers.

Abstract: Overlaying a Wireless Macro Cell architecture on a Micro Cell network. WLAN MAC Address Translation (WMAT) is used to translate BSSIDs from the BSSID used to initialize a radio in an access node and identify communications between the radio in the access node and a controller, and the BSSID used over the air for Macro Cell operation. WMAT is used for transmit operations, translating the BSSID of outgoing packets to the Macro Cell BSSID prior to wireless transmission. On the receive side, packets undergo WMAT and transmission to the controller if the STN MAC address of the sender is in an ACK table associated with the radio, or the packet is one of a predetermined type. The ACK table is managed by transmit operations, and by control commands from the controller.
