Synchronizing playback by media playback devices
Example systems, apparatus, and methods receive audio information including a plurality of frames from a source device, wherein each frame of the plurality of frames includes one or more audio samples and a time stamp indicating when to play the one or more audio samples of the respective frame. In an example, the time stamp is updated for each of the plurality of frames using a time differential value determined between clock information received from the source device and clock information associated with the device. The updated time stamp is stored for each of the plurality of frames, and the audio information is output based on the plurality of frames and associated updated time stamps. A number of samples per frame to be output is adjusted based on a comparison between the updated time stamp for the frame and a predicted time value for play back of the frame.
Voice interaction scripts
This disclosure describes systems and methods that identify activities for which scripts can be built to perform an activity when requested by a user. The scripts can be voice-activated by a defined customized voice command and can include delivery preferences. The user's identity can be verified by analyzing voice biometrics of the customized voice command. After performance of the activity, results can be delivered to the device in the format indicated in the script.
Continuing a media access control security (MACsec) key agreement (MKA) session upon a network device becoming temporarily unavailable
A network device may communicate with another network device via a media access control security (MACsec) key agreement (MKA) communication link, wherein an MKA session has been established between the network device and the other network device. The network device may determine that the other network device is unavailable. The network device may cause, based on determining that the other network device is unavailable, an MKA state of the network device to be placed in a paused state. The network device may receive, after causing the MKA state of the network device to be placed in the paused state, a packet from the other network device via the MKA communication link. The network device may determine, based on the packet, that the MKA session has not ended. The network device may continue, based on the MKA session having not ended, the MKA session by reactivating the MKA state.
System and method for providing an enhanced acknowledgement frame
A system for providing an enhanced acknowledgement (ENH-ACK) frame is configured to receive an incoming packet transmitted by an external device, determine that an ENH-ACK response is required based on a MAC header of the incoming packet schedule transmission of the ENH-ACK frame to the external device in accordance with a standard turnaround time limit relative to receipt of the incoming packet, determine contents of one or more packet processed fields of the ENH-ACK frame and populate the one or more packet processed fields, and complete transmission of the ENH-ACK frame with the populated packet processed fields.
METHOD AND SYSTEM FOR USING DATA PACKET TRANSMISSION TO DETERMINE COMPLIANCE WITH PROTOCOLS
One or more computing devices, systems, and/or methods for determining a time-length of an action are provided. For example, a first event may be detected. Responsive to detecting the first event, a first inquiry may be transmitted in a first direction, using a first device. The first inquiry may be received by a second device. Responsive to receiving the first inquiry, a first reply data packet, comprising an identification number associated with the second device, may be transmitted, using the second device, to the first device. A second event may be detected. Responsive to detecting the second event, a second inquiry may be transmitted in a second direction, using a third device. The second inquiry may be received by the second device. Responsive to receiving the second inquiry, a second reply data packet, comprising the identification number, may be transmitted, using the second device, to the third device.

ORTHOGONAL MULTIPLEXING OF HIGH EFFICIENCY (HE) AND EXTREMELY HIGH THROUGHPUT (EHT) WIRELESS TRAFFIC
This disclosure provides systems, methods, apparatus, including computer programs encoded on computer storage media for orthogonal multiplexing of high efficiency (HE) and extremely high throughput (EHT) wireless traffic. Devices in a wireless local area network (WLAN) may operate under HE or EHT conditions. An access point (AP) may support both HE and EHT communications with WLAN devices. To enable substantially simultaneous downlink HE and EHT transmissions and substantially simultaneous uplink HE and EHT transmissions, the AP may support orthogonal frequency-division multiple access (OFDMA) of HE and EHT transmissions. For example, pre-HE and pre-EHT modulated fields, HE and EHT modulated fields, and payloads may be aligned in time for the HE and EHT transmissions. The AP may ensure orthogonality for multiplexing the HE and EHT transmissions based on the alignment. In some implementations, a trigger frame may be utilized to indicate uplink transmission alignments.
