International Classification:

H04L 12/26

Abstract:

An apparatus, computer program product, and method relating to identifying and configuring an access point (AP) as a network sniffer. A network controller identifies a plurality of sniffer targets for which at least one of a plurality of sniffer candidate access points an act as a network sniffer. The controller receives a desired sniffer target. The controller selects a first AP, of the plurality of sniffer candidate APs, for use as a network sniffer, based on the identified plurality of sniffer targets and the desired sniffer target. The controller configures a radio in the first AP as a network sniffer to monitor network traffic related to the desired sniffer target.

Appl. No.:

14/528087

Inventors:

- Sunnyvale CA, US
Manoj Gupta - Santa Clara CA, US

International Classification:

H04W 28/04
H04W 72/08

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.

Inventors:

- Sunnyvale CA, US
Manoj Gupta - Santa Clara CA, US

International Classification:

H04L 5/00
H04W 16/28

Abstract:

The present disclosure discloses a system and method for dynamic control of channel sounding for transmit beamforming. Generally, sounding frames are periodically transmitted by a network device to a particular device at a first sounding interval. First feedback information is received from the particular device. The first feedback information corresponds to the sounding frames transmitted at the first sounding interval. Based on one or more current conditions included in the feedback information, a second sounding interval is selected to transmit the sounding frames to the particular device. The sounding frames are periodically transmitted to the particular device at the second sounding interval. Second feedback information is received from the particular device. The second feedback information corresponds to the sounding frames transmitted at the second sounding interval.

Assignee:

ARUBA NETWORKS INC. - Sunnyvale CA

International Classification:

H04L 12/725
H04L 12/853
H04L 12/801
H04W 48/20

Abstract:

A non-transitory computer readable medium includes instructions which, when executed by one or more hardware processors, cause performance of operations including determining a priority level for an Access Point (AP). Subsequent to determining the priority level for the AP, the instructions further cause performance of operations including receiving multiple packets, determining one or more transmission parameters for transmitting the packets based at least in part on the priority level of the AP, and transmitting the packets using the one or more transmission parameters that were determined based at least in part on the priority level of the AP.

Assignee:

Aruba Networks, Inc. - Sunnyvale CA

International Classification:

H04L 12/24

US Classification:

370221

Abstract:

According to one embodiment of the disclosure, a non-transitory computer readable medium is described for an network device, where the medium comprising instructions which, when executed by one or more hardware processors, cause performance of a number of operations. These operations include configuring a first network device to provide network access to a client device using a first Basic Service Set Identification (BSSID) and determining that the first network device is not responsive. Based on determining that the first network device is not responsive, the one or more hardware processors further configure a second network device to provide the network access to the client device using the same first BSSID that was previously used by the first network device without the client device disassociating with the first BSSID.
