Abstract: Airtime usage may be used as a factor in controlling network traffic flow to and from client devices via a wireless network interface. Received packets or other data are assigned to a quality of service profile. Additionally, a cost value for communicating the received data is determined at least in part based on an actual or estimated airtime usage for the received packet. The cost value is used to allocate wireless network airtime to data. The allocation of wireless network airtime may be varied dynamically based on operating conditions. The cost value may be based on factors including the airtime used to communicate data; whether the data is a retransmission; and wireless network overhead. The cost value of data may also be different depending on whether the data is being sent from a client device or to a client device.

Abstract: Wireless access points detect neighboring wireless access points in different subnets. Upon connecting with a wireless client, a wireless access point determines predictive roaming information for the wireless client. Predictive roaming information identifies the wireless client; its home network subnet; and includes connection information associated with the wireless client. The wireless access point forwards the predictive roaming information associated with a wireless client to neighboring wireless access points while the wireless client is still connected with the wireless access point. Neighboring wireless access points store received predictive roaming information. Upon connecting with a wireless client, a neighboring wireless access point determines if the wireless client matches the stored predictive roaming information.

Abstract: Management of a proximity beacon transmitter using a network device. Operational characteristics are generated for a proximity beacon transmitter coupled to a network device. The proximity beacon is configured through the network device. It is determined if the proximity beacon transmitter is operating according to the operational characteristics generated for the proximity beacon transmitter. The proximity beacon transmitter is reconfigured to operate according to the operational characteristics if it is determined that the proximity beacon transmitter is operating in nonconformity with the operational characteristics.

In some implementations, the communication interface can be embedded within the network device, such that the communication interface can provide the physical connection in the form of an embedded or internal connection.

Abstract: Wireless networking devices scan for available channels and gather data about the channels and the RF environment. Using this information, each wireless networking device determines a cost value for each available channel and a quality value for its overall RF neighborhood. Each wireless networking device select the channel with the best cost value as a candidate channel for use. The wireless networking devices may submit channel requests to the arbiter for approval. If two or more wireless networking devices are requesting the same channel, the arbiter assigns the channel to the wireless networking device with the worst RF neighborhood quality. The arbiter informs the wireless networking devices if their channel requests are approved. If a wireless networking device's channel request is not approved, the wireless networking device will rescan the remaining available channels to select a different candidate channel to be approved.

Abstract: A method and system for selecting a route in a wireless network for the transmission of a data packet between wireless nodes in the network using a modified link-state routing algorithm. A subset of nodes called portal nodes within the network are elected to do the broadcasting for the entire network. A wireless node identifies a unicast route back to its root portal node, and sends a link-state register message to this portal node. These link-state register messages received by each portal node are aggregated by them and are broadcast to each of the wireless nodes for storage. When a data packet is thereafter received by a wireless node from a neighboring node, it detects if the data packet satisfies one of a plurality of predetermined conditions and rebroadcasts the data packet to neighboring wireless nodes if none of the conditions is satisfied.

Abstract: A method and system for selecting a route in a wireless network for the transmission of a data packet between wireless nodes in said network using a modified link-state routing algorithm wherein only a limited number of broadcast messages are generated to synchronize the link-state database throughout the wireless network. A subset of nodes called portal nodes within the network are elected to do the broadcasting for the entire network. Each portal node broadcasts an announcement of its identity to all of the wireless nodes. Each wireless node responds to these broadcasts to select one of the portal nodes as its root portal node. It then identifies a unicast route back to its root portal node, and sends a link-state register message to this portal node. These link-state register messages received by each portal node are aggregated by them and are broadcast to each of the wireless nodes for storage.

Abstract: Various implementations described herein relate to routing network data traffic using network tunnels. In some implementations, one or more tunnels are established between a remote gateway device and a central gateway device central gateway system. The remote gateway device can receive data traffic from one or more client devices and analyzed the data traffic. Based at least in part on the resulting analysis, the remote gateway device identified an application or an application type associated with the data traffic. The remote gateway device can select one or more select tunnels, from the one or more tunnels, based at least in part on the identification of the application or the application type associated with the data traffic. Eventually, the remote gateway device can route the data traffic to the central gateway system using the one or more select tunnels.

Abstract: Various implementations described herein relate to routing network data traffic using network tunnels. In some implementations, one or more tunnels are established between a remote gateway device and a central gateway system. The central gateway system receives data traffic-to-tunnel information from the remote gateway device, and the central gateway system incorporates the data traffic-to-tunnel information in a data traffic-to-tunnel mapping. The data traffic-to-tunnel information comprises n-tuple of network flow information, network flow tags, application-to-tunnel binding information, or the like. The central gateway system receives first data traffic from the remote gateway and forwards the first data traffic to a server. Subsequently, the central gateway system receives second data traffic and forwards the first data traffic to the remote gateway device over one or more select tunnels selected from the established tunnels.
