  • Patent number: 9515988
    Abstract: Automatically configuring split DNS operation in a wireless network device connected to a network. The wireless network device snoops one or more exchanged DHCP messages to obtain domain name(s) associated with the organization that are now used as target domain name suffix(es) for split DNS operations. For subsequent DNS queries, information within the message is analyzed to determine if the request includes a domain delimiter. If no delimiter, the DNS query message is sent to an internal DNS server that is located within an organization. If a delimiter exists, but the domain name in the message matches one of the target domain name suffixes, the DNS query message is sent to the internal DNS server as well. Otherwise, the DNS query message is routed over a different communication path.

  • Patent number: 9516672
    Abstract: A method is described for intelligently toggling request-to-send/clear-to-send (RTS/CTS) mechanisms on and off for a channel between an access point and a client device. In particular, the method may determine one or more characteristics related to the transmission of frames and toggle RTS/CTS based on these characteristics. The characteristics may describe (1) the airtime used to transmit frames, (2) the data rate used to transmit frames, (3) traffic measurements on the wireless channel between the access point and the client device, (4) overlapping basic service set traffic measurements, and (5) the number of data units included in frames to be transmitted. By toggling RTS/CTS on and off based on network/channel and frame conditions/characteristics, the method ensures that RTS/CTS is enabled when frame collisions are likely and/or channel capacity is low and disabled when frame collisions are unlikely and the overhead associated with RTS/CTS outweighs the potential benefits.

  • Publication number: 20160352796
    Abstract: A network system and the method is described that splits media identification logic and media classification and/or general data session processing/management logic into separate controllers (e.g., between the local controllers and a service controller). By separating media identification logic and media classification logic (or general media processing/management logic), the system and method allows for greater flexibility and scalability in a network system employing a service controller. In particular, by allowing the local controllers to perform media identification and to construct a single packet that characterizes/describes a media session, the system avoids the need to transmit multiple data packets of a media session to the service controller for classification of the session.

  • Patent number: 9509785
    Abstract: The present disclosure discloses a method and network device for providing location approximation and discovery of wired servers in a network. Specifically, a network device can store information indicating that a first client device, with a first set of one or more characteristics, selected a particular shared device from a plurality of shared devices of a first type. The network device then receives, from a second client device, a request for a shared device of the first type. Subsequently, the network device determines that the second client device is associated with the same first set of characteristics as the first client device that selected the particular shared device. Responsive to such determination, the network device presents the particular shared device as an option for selection by the second client device.

  • Patent number: 9509746
    Abstract: Provisioning remote access points for use in a telecommunication network. A remote access point contains identity information established during manufacturing; this identity information may be in the nature of a digital certificate. The identity information is stored in the remote access point, and may be stored in a Trusted Platform Module if present. When the remote access node is powered up in unprovisioned state, outside the manufacturing environment, it attempts to establish an internet connection via a first wired interface, and queries a user for information representing the TCP/IP address of its controller via a second wired interface. Once an internet connection is present, and a TCP/IP address has been provided, the remote access point attempts to connect to the controller at that address. Once a connection is established, controller and access point exchange and verify each other's identities.

  • Patent number: 9509661
    Abstract: The present disclosure discloses a method and system for displaying an HTTPS block page without SSL inspection. Specifically, a network device snoops a first message transmitted between a client device and a network resource. The first message is transmitted as part of a SSL Handshake between the client device and the network resource to establish a SSL session. Moreover, the network device determines whether the client device is authorized to access the network resource. If not, the network device blocks the establishment of a SSL session between the client device and the network resource, and spoofs the network resource for establishing the SSL session between the client device and the network device instead of establishment of the SSL session between the client device and the network resource. Otherwise, the network device refrains from blocking the establishment of the SSL session between the client device and the network resource.

In response, the network device selects a particular client device, of the plurality of client devices associated with the access point, for disassociation with the access point. The network device then causes the particular client device to disassociate with the access point.

  • Patent number: 9479954
    Abstract: A combination and correlation of data from multiple sensors in a wireless digital network is described. Sensors such as spectrum monitors, access points, and wireless client devices provide spectrum data to one or more central stations connected to the network. Spectrum data from multiple sensors is combined and correlated to provide insight into network operation such as spectrum maps, detection-range maps, and for network diagnostics. Sensors providing spectrum data may be synchronized. Correlating spectrum data from synchronized sensors allows more accurate location of sources such as interferers. The known EIRP of certain wireless devices may be used to improve location estimates, and these devices may be used as calibrations sources for sensors in the wireless network.

  • Patent number: 9473285
    Abstract: A system or method that receives a current request from a client, and responds to the current request based on signal strength associated with a previous request. If the current request is received on a non-preferred communication band, and a previous request was received on a preferred communication band within a pre-determined time, the system determines whether the signal strength associated with the previous request is weaker than a pre-determined threshold signal strength level for the preferred communication band. If so, the system responds to the current request. Otherwise, the system ignores the current request. If no recent request on the preferred communication band is received, and the signal strength associated with the current request is weaker than a pre-determined threshold signal strength level for the non-preferred communication band, the system responds to the current request on the non-preferred communication band. Otherwise, the system ignores the current request.
