Patent number: 11838862Abstract: In one embodiment, a first wireless access point (AP) of a first basic service set (BSS) receives, from a second wireless AP of a second BSS, data indicative of an 802.11-based target wake time (TWT) schedule of a client of the second BSS. The first wireless AP identifies, from the receive data, a scheduled communication time of the client of the second BSS in the TWT schedule. The first wireless AP generates an 802.11-based TWT schedule for a client of the first BSS that avoids the scheduled communication time of the client of the second BSS. The first wireless AP sends the generated 802.11-based TWT schedule to the client of the first BSS, wherein the sent TWT schedule causes the client of the first BSS to wake from sleep at a scheduled wake time.Type: GrantFiled: November 9, 2021Date of Patent: December 5, 2023Assignee: Cisco Technology, Inc.Inventors: Pooya Monajemi, Gautam Bhanage, David Kloper, Young Il Choi, Vishal Satyendra Desai, Santosh Bahaji Kulkarni

Patent number: 11601469Abstract: A management entity obtains from a first wireless access point a Basic Service Set (BSS) color collision event detected by the first wireless access point. The first wireless access point uses a first BSS color. A color collision event occurs when the first wireless access point receives from a device in a BSS of a different physical wireless access point a frame or PHY Protocol Data Unit (PPDU) that includes the first BSS color. The management entity obtains from the first wireless access point an indication whether the color collision event has been detected for longer than a predetermined duration. When the color collision event has been detected for longer than the predetermined duration, the management computes a probability of the color collision event. The management entity determines whether the color collision event is malicious or benign, and determines whether to maintain the first BSS color.Type: GrantFiled: April 6, 2021Date of Patent: March 7, 2023Assignee: CISCO TECHNOLOGY, INC.Inventors: Gautam Bhanage, David Kloper, Brian Hart

Patent number: 10638424Abstract: The present disclosure discloses a method and network device for automatic delivery traffic indication message (DTIM) interval control for better mobile power save performance. The disclosed network device determines one or more characteristics for at least one client device connected to an Access Point (AP). The network device then dynamically selects a DTIM interval for the AP based on the characteristics for the at least one client device, and configures the AP to transmit a DTIM beacon frame at a frequency based on the dynamically selected DTIM interval. Alternatively, the network device can determine one or more characteristics for a client device, and dynamically select a Virtual Access Point (VAP) for providing network access to the client device based on the characteristics for the client device and a DTIM interval configured for the VAP, and then cause the client device to connect to the VAP.Type: GrantFiled: July 9, 2018Date of Patent: April 28, 2020Assignee: HEWLETT PACKARD ENTERPRISE DEVELOPMENT LPInventors: Gautam Bhanage, Partha Narasimhan

Patent number: 10602401Abstract: A method for performing aggregation at one or more layers starts with an AP placing at a first layer one or more received frames in a queue at the AP. When a transmit scheduler is ready to transmit an aggregated frame corresponding to the queue, the AP may iteratively select a plurality of frames selected from the one or more received frames, and aggregate at the first layer the plurality of frames into the aggregated frame. The number of frames included in an aggregated frame may be based on at least one of: a dynamically updated rate of transmission associated with a size of the frames, a class of the frames, a transmission opportunity value associated with the class of the frames and a total projected airtime for transmitting the aggregated frame. Other embodiments are also described.Type: GrantFiled: April 5, 2016Date of Patent: March 24, 2020Assignee: HEWLETT PACKARD ENTERPRISE DEVELOPMENT LPInventors: Gautam Bhanage, Sathish Damodaran

Patent number: 10397873Abstract: MAC addresses provide a way to identify wireless client devices. Some wireless client devices are able to change their MAC addresses. Provided are devices computer-program products, and methods for identifying wireless client devices based on radiofrequency signatures of transmissions from the client devices. In some implementations, one or more wireless frames are received at a network device. In these implementations, a wireless frame is received at two or more antennas. In some implementations, a signal characteristic associated with transmission of the wireless frame is monitored. In these implementations, monitoring the signal characteristic includes using two or more antennas to determine a physical or temporal characteristic associated with the transmission of the wireless frame. In some implementations, a client device is identified. The identified client device is associated with the transmission of the wireless frame.Type: GrantFiled: April 20, 2018Date of Patent: August 27, 2019Assignee: Hewlett Packard Enterprise Development LPInventor: Gautam Bhanage
