  • Publication number: 20140036893
    Abstract: The present disclosure discloses a method and network device for enforcing uplink airtime fairness in wireless local area networks. The disclosed network device receives usage limits associated with transmissions from one or more client devices. The client devices transmit packets to the network device via one or more uplink wireless mediums. The disclosed network device further collects wireless medium usage times associated with the client devices, and calculates a size for transmission windows corresponding to the client devices based on the wireless medium usage times and the usage limits. The transmission windows can be TCP advertisement windows whose size determines a rate of transmissions permitted over the wireless medium. Then, the disclosed network device sets the transmission window to the calculated size.

  • Publication number: 20130100807
    Abstract: According to one embodiment of the invention, a method for optimizing revenue for an operator of a network comprises receiving control information by a network device. The control information includes a first airtime representing an amount of airtime used for wireless data transmissions to a first group of network devices. The method further involves an operation of computing an airtime allocation for the first group of network devices based on the first airtime and lease rates. The lease rates are prices per unit of airtime to be paid by an operator associated with one or more of the network devices.

  • Publication number: 20130036188
    Abstract: Infrastructure-based client management uses synthesized beacon reports to effect client association with APs in a wireless digital network. Beacon reports are synthesized by having a plurality of APs in the network collect client reports and send those reports to a report process on the network. The report process accumulates client reports from the plurality of APs and selects one or more candidate APs to support a client. Selection may be made on reported SNR, AP loading, channel loading, AP characteristics, or a combination. The report process may produce blacklists and optionally whitelists for use by APs to use in processing client probe and connection requests.

  • Publication number: 20120170455
    Abstract: Herein, a method directed to receiving, by a network device, client density data of a first access node in a plurality of access nodes in a network. Also, the network device receives client density data of a second access node in the plurality of access nodes. The network device determines whether the client density data of the first access node overlaps with the client density data of the second access node. In response to the received client density data of the first access node overlapping with the received client density data of the second access node, the network device identifies the first access node and the second access node as members of a virtual radio frequency (RF) neighborhood, wherein the virtual RF neighborhood comprises a subset of a RF neighborhood. Each member of the virtual RF neighborhood is capable of receiving beacons from other members of the virtual RF neighborhood.

  • Patent number: 8155058
    Abstract: Client balancing in a wireless digital network comprising a plurality of access nodes connected to a controller. Access nodes collect client density information and periodically report that client density information to the controller. The controller uses the client density information from the access nodes to compute Virtual RF Neighborhoods, identifying Virtual RF neighboring access nodes. Two access nodes are Virtual RF neighbors if a client which can connect to one access node can also connect to the other access node. The controller then identifies which nodes are overloaded by comparing the client loading of a target access node to the client loading of its Virtual RF neighbors. If an access node is identified as overloaded and selected for client balancing on a particular channel, it will initially refuse new association requests from client devices on that channel.
