In various embodiments, the disclosed methods and systems provide for synchronizing access points (APs) in the same channel. Based on the synchronizing, the APs in the same OBSS channel can determine a distribution policy for using frame bursting. Each AP can use frame bursting in accordance with the distribution policy. In various embodiments, the APs can periodically send frame burst synchronization packets. The frame burst synchronization packets can indicate respective numbers of client devices associated with each AP. Based on the frame burst synchronization packets sent by the APs, a total number of client devices using the same channel can be determined. The distribution policy for using frame bursting can be determined based on the total number of client devices.

  • Patent number: 11663073
    Abstract: An apparatus and method for efficiently transmitting data are described. A transmitter sends data to a receiver. An encoder of the transmitter divides a received first block of data into multiple sub-blocks. The encoder selects a portion of each sub-block to compare to one another. A portion in a particular sub-block has a same offset and a same size as other portions of other sub-blocks. If the encoder determines the multiple portions match one another, the encoder sends, to the receiver, a second block of data corresponding to the first block of data. The second block of data has a same size as a size of the received first block of data, and the second block of data includes security data from one of multiple error correction schemes. Therefore, the second block of data provides security without increasing an amount of data to transmit.

  • Patent number: 11470622
    Abstract: A system, communication device, and method for scheduling transmissions from the communication device. The device predicts an arrival time of a next packet for transmission when a current packet arrives in a transmission buffer. The device plans a future transmission time of the next packet based on the predicted arrival time of the next packet, and books transmission resources for the planned future transmission time. If the next packet has arrived a Tdrop time period before the planned future transmission time, the device transmits the next packet. If the next packet has not arrived at that time, the device re-plans the future transmission time of the next packet. The device may then unbook the transmission resources for the planned future transmission time, book transmission resources for the re-planned future transmission time, and notify other communication devices that the unbooked transmission resources are available for use by the other communication devices.

  • Patent number: 11451481
    Abstract: A data collection unit of an NW controller (6) collects, from an L2SW (5) constituting an L2NW (4), uplink observation data indicating traffic volume of a session request packet addressed to an application server 2 and downlink observation data indicating traffic volume of a session response packet transmitted from the application server 2, which are acquired by observing packets input to the L2SW (5). A control unit changes shaping rate of the packets addressed to the application server (2) through the L2SW (5) included in the L2NW (4) based on a ratio between the traffic volume indicated by the uplink observation data and the traffic volume indicated by the downlink observation data, or a ratio between an increment of the traffic volume acquired from the uplink observation data and an increment of the traffic volume acquired from the downlink observation data.
