    Abstract: Techniques herein facilitate a device address rotation management protocol that may be implemented for a wireless local area network (WLAN), which can be used to influence when wireless client devices or stations may rotate their Media Access Control (MAC) addresses, how to perform such rotations, and/or the like. In one example, a method may include providing, by an access point (AP), a first communication indicating that the AP supports a MAC address rotation management protocol; obtaining, by the AP, a second communication from a wireless station (STA) indicating that the STA intends to perform a MAC address rotation; and transmitting, by the AP, a third communication to influence the MAC address rotation of the STA, the third communication comprising a rotation status indicator and timing information.

    Abstract: Audio samples are obtained from a plurality of microphones in a conference room that includes a plurality of participants of an online communication session. A cross correlation is calculated between audio samples for each microphone pair of the plurality of microphones. For each participant, a distance between the participant and each microphone is estimated and, for each microphone pair, an expected delay between when microphones in a microphone pair receive audio from a participant is calculated based on the distance. For each participant, a score is computed based on the cross correlation for each microphone pair and the expected delay for each microphone pair and the participant that is speaking is identified based on the score computed for each participant.

    Abstract: In one embodiment, an illustrative method herein may comprise: obtaining, by a device, one or more independent telemetry streams, wherein each of the one or more independent telemetry streams is uniquely identifiable by a span identifier; translating, by the device, each of the one or more independent telemetry streams into a corresponding QUIC protocol stream; mapping, by the device, the span identifier of each of the one or more independent telemetry streams to a respective stream identifier that uniquely identifies a QUIC channel of a multiplexed QUIC protocol stream; and communicating, by the device, the multiplexed QUIC protocol stream containing each of the one or more independent telemetry streams on its corresponding QUIC channel to cause a retrieving device to determine the span identifier of each of the one or more independent telemetry streams based on their respective stream identifier.

    Abstract: Techniques for leveraging efficient metadata communications to improve domain name system (DNS) security are described. The DNS service receives metadata associated with a client device on an encrypted channel. The DNS service applies a cryptographic hash function to the metadata to determine a first hash value and stores the first hash value in a metadata registry record with the corresponding client device metadata. The DNS service receives a DNS query containing a second hash value in an additional records section and determines that the second hash value corresponds to the first hash value. Based at least in part on the second hash value corresponding to the first hash value and the metadata associated with the client device, the DNS service resolves the DNS query and transmits a DNS response including the second hash value.

    Abstract: In one embodiment, a method comprises: establishing, from an agent hub device, a tunnel to a remote vantage point device; generating, by the agent hub device, test traffic to appear as though the test traffic originates from the remote vantage point device; encapsulating, by the agent hub device, the test traffic into the tunnel to the remote vantage point device to cause the remote vantage point device to decapsulate the test traffic and send the test traffic as though the test traffic originated from the remote vantage point device; receiving, at the agent hub device, one or more returned test responses in response to the test traffic; and producing, by the agent hub device, test results based on the one or more returned test responses.

    Abstract: Presented herein are techniques in which a first device connects to a communication session in which a plurality of devices communicates. The plurality of devices includes the first device and a second device. The first device outputs first audio that includes a first audio watermark associated with the communication session and the second device outputs second audio that includes a second audio watermark associated with the communication session. The first device detects the second audio watermark in the second audio outputted by the second device and one or more actions are performed in response to detecting the second audio watermark
