20150124774 | AGGREGATED BEACONS FOR PER STATION CONTROL OF MULTIPLE STATIONS ACROSS MULTIPLE ACCESS POINTS IN A WIRELESS COMMUNICATION NETWORK - A technique for providing per station control of multiple stations in a wireless network across multiple access points. A look-up table that assigns a station connected to the access point and at least one communication parameter to each of a plurality of persistent, uniquely-assigned BSSIDs (Basic Service Set Identifiers) is stored. An access point responds to messages addressed one of the plurality of persistent, uniquely-assigned BSSIDs and ignores messages addressed to other BSSIDs. Persistence of the BSSID allows the controller to maintain individual control over each station after moving to a second access point of the plurality of access points. A frame comprising the plurality of BSSIDs corresponding to each connected station aggregated into the frame is generated. The frame is transmitted to the plurality of stations. Responsive to a station of the plurality of stations being handed-off to a different access point, a uniquely-assigned BSSID corresponding to the station is deleted from the look-up table. | 05-07-2015 |
20160100399 | EMULATING VIRTUAL PORT CONTROL OF AIRTIME FAIRNESS USING PER STATION ENHANCED DISTRIBUTED CHANNEL ACCESS (EDCA) PARAMETERS - A technique for emulating virtual port control of airtime fairness for wireless stations using per station Enhanced Distributed Channel Access (EDCA) parameters. Specific parameters are received for each of a plurality of stations connected to the access point. An EDCA field of a beacon that stores a general EDCA parameter is set to an empty state. The beacon is broadcast to a plurality stations on the wireless communication network and within range of an access point. The beacon comprises a BSSID (Basic Service Set Identifier) for use by the plurality of stations to connect with the access point for access to the wireless communication network. The beacon also comprises an empty EDCA field. In response to broadcasting the empty EDCA parameter, receiving a direct inquiry from each of the plurality of stations for the general EDCA parameter. Each of the plurality of stations is responded to with a direct communication of a specific parameter corresponding to each station. A transmission is received from at least one of the stations complying with the specific parameter. | 04-07-2016 |
20160105824 | DYNAMIC GENERATION OF PER-STATION REALM LISTS FOR HOT SPOT CONNECTIONS - Per-station realm lists are dynamically generating per-station for hot spot connections to access points by roaming stations. A query for a list of realms is received from a roaming station when connecting to a hot spot. Using an MAC address or other station identity, a list of available realms narrowed to a subset of per-station realms sent to the station. Narrowing is performed on-the-fly with respect to at least one aspects. A last N realms are retrieved from a database record searched by MAC address. The list is further narrowed by removing realms that are inaccessible or otherwise recently shown to have bad link quality. Additional ranking factors can narrow or rearrange the realm list based on financial agreements, popularity, trends, and the like. A selection from the list of realms is received from the station. The access point then authenticates the station with the selected realm. If successful, data traffic concerning the station can be forwarded through the hot spot on behalf of the selected realm. | 04-14-2016 |

A message is received on an instant messenger application executing on the network infrastructure device. The message is sent from an authorized party or instant messenger friend. The message is mapped to one or more commands recognized by an operating system of the network infrastructure. Commands are submitted on a command line interface. A response to the one or more commands from the network infrastructure device is received on the command line interface. The response is sent on the instant messenger to the authorized party. | 04-21-2016 |
20160112728 | OPTIMIZING MULTIMEDIA STREAMING IN WLANS (WIRELESS LOCAL ACCESS NETWORKS) - An SDN controller to provision network resources at a data plane to keep progressive downloads of multimedia files proportional to encoding rates is disclosed. Packets from a new or unknown flow being downloaded at a default rate are forwarded from an access point, or other device, to an SDN controller for analysis. If a progressive download of a multimedia file (e.g., a video file) in progress is detected, an encoding rate of frames for the multimedia file is determined. A target download rate for the multimedia file at the access point is determined based on the encoding rate, in an embodiment. Other optional factors also take into account network-wide data plane information gathered by the SDN controller from various points on the network. Additionally, a playback history for a particular multimedia file can affect the target download rate, based on whether, for example, a file is likely to be quickly halted. | 04-21-2016 |
20160112838 | BEACONS TO ADVERTISE PRESENCE OF NEARBY OBJECTS TO STATIONS IN A WIRELESS COMMUNICATION NETWORK - Beacons (e.g., mBeacons or meruBeacons) to advertise presence of nearby objects to stations in a wireless communication network from an access point are provided. Location of a station connected to the access point is detected. One or more physical objects having a location proximate to the station are identified and can be indicated to a user. To do so, in an embodiment, responsive to the proximity of locations, a beacon having a BSSID corresponding to each of the one or more physical objects is generated. The BSSID can uniquely identify the one or more physical objects. The beacon is transmitted the station which can request additional information concerning the one or more physical objects. For example, an Amazon listing for a nearby retail item can be automatically displayed on a smartphone. | 04-21-2016 |

A stream of beacons (e.g., iBeacons) comprising at least a unique source identifier is generated. The stream of beacons is broadcast over a wireless communication channel to mobile devices within range. A list of broadcasted beacons is stored in a table along with a time and location of broadcast. Subsequent to broadcasting, a stream of beacons is detected. The detected beacon stream comprises a unique source identifier along with a time and a location of broadcast. The unique source identifier, the time and the location of at least one beacon of the detected beacon stream can be compared to the unique source identifier, the time and the location of at least one beacon of the broadcast beacon stream. Responsive to a match between the unique source identifiers and a mismatch of at least one of the time and locations, it is determined that the broadcast beacon stream has been spoofed by the detected beacon stream. Once a spoof has been detected, various remediation actions can be taken, such as sending alerts to admin, cautioning end users, and other security mode procedures. | 04-21-2016 |
