Abstract: A method for providing multicast frames in a Multi-Dwelling Unit (MDU) is provided herein. An Access Point (AP) can receive a join request from a first client device. The AP can generate a Group Master Key (GMK) from the Pre-Shared Key (PSK) associated with a Basic Service Set (BSS) that includes the first client device. The AP can then derive a Group Transient Key (GTK) from the GMK. The AP may then send the GTK to the first client device. Thereinafter, the AP can send multicast frames to the first client device encrypted by the GTK. The first client device can decrypt the multicast frames with the GTK. However, a second client device, that does not share the PSK, may receive the multicast frame but cannot decrypt the multicast frames.

Abstract: Presented herein are techniques for extending Target Wake Time (TWT) to provide for randomizing and changing media access control (MAC) address (RCM) signaling. According to certain embodiments, a client device operating in a wireless network determines a TWT for the client device. Next, the client device determines that it will change from using a first MAC address to a using second MAC address. Finally, the client device generates, for transmission to an access point device that serves wireless communication in the wireless network, a TWT signaling message. The TWT signaling message indicates the TWT for the client device and the second MAC address.

Abstract: Techniques are provided that rotate a device address used to identify a wireless client device on a wireless network. The wireless client device and at least one network infrastructure component identify a plurality of device addresses associated with the wireless client device. In some embodiments, the plurality of device addresses are generated via a corresponding plurality of invocations of a stateful random number generator, such as a cryptographically secure pseudorandom number generator.

Abstract: The present disclosure is directed to systems and methods that enable automatic provisioning of access points within an enterprise network by a controller of the enterprise network. In one aspect, a method includes detecting, at a network controller, attachment of a first access point to a network; identifying, by the network controller, a profile of a second access point, the second access point having being replaced with the first access point, the profile including at least one of identification parameters and configuration parameters of the second access point; and provisioning, by the network controller, the first access point with the profile of the second access point.

Abstract: Techniques for improving telemetry in resource-constrained device environments. In some examples, the techniques include gossiping telemetry information between peer devices of a wireless network to, among other things, reduce telemetry cost and/or an amount of telemetry data streamed to a telemetry collector. In some examples, the techniques may also include intelligently exporting telemetry data from resource-constrained devices towards backend systems without exhausting the resource-constrained devices and/or the backend systems. In examples, the telemetry data may be contextual information associated with an endpoint, an application, a network-device resource (e.g., CPU, battery, memory, storage, etc.), geographical constraints, and/or the like.

Abstract: In one embodiment, a client device enters an area having an overhead mesh of access points, each access point comprising one or more directional transmitters each configured to transmit a beam cone in a substantially downward direction towards a floor of the area. The client device obtains an area-dependent communication schedule for the overhead mesh that is exclusive or partially-exclusive to the client device for the area. The client device sends, during an arbitrary timeslot of the area-dependent communication schedule, a pull request. The client device receives, from a particular access point in the overhead mesh, a packet in response to the pull request.

Abstract: Balancing Multi-link Operation (MLO) usage may be provided. A list of a plurality of Access Points (APs) for each of a plurality of Multi-link Operation (MLO) types indicating availability of each of the plurality of APs may be received. A first request indicating an MLO type associated with the first request is a first MLO type may be received. In response to the first request, a first subset of the list of the plurality of APs that support the MLO type associated with the first request may be sent. A second request indicating that an MLO type associated with the second request is the first MLO type may be received. In response to the second request, a second subset of the list of the plurality of APs that support the MLO type associated with the second request may be sent. The first subset is different from the second subset.

Abstract: A method is performed at a mesh access point (MAP) of a mesh network in which MAPs are configured to communicate with each other over wireless backhaul links. The method includes: receiving, from a first wireless client having a first client address, client traffic destined for a second wireless client having a second client address, the client traffic including a first source address that represents the first client address, and a first destination address that represents the second client address; generating a first obfuscated source address that differs from the first client address; replacing the first source address in the client traffic with the first obfuscated source address; and transmitting the client traffic with the first obfuscated source address in place of the first source address to a next MAP of the MAPs over a wireless backhaul link for subsequent forwarding to the second wireless client.
