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: In one embodiment, a device determines a physical location of a mobile client of wireless network. The device performs a frequency lookup for the mobile client from an AFC service using the physical location of the mobile client. The device selects a frequency to be used by the mobile client based on the frequency lookup. The device causes the mobile client to use the frequency to communicate with the wireless network.

Abstract: Techniques are provided for read-based storage of time-series records. In one example, a server obtains at least one indication of one or more records of a plurality of records written to a record database by a producer that have been read from the record database by at least one consumer. The server stores in a time-series database the one or more records that have been read by the at least one consumer. One or more records of the plurality of records that have not been read by the at least one consumer may be pruned from storage in the time-series database.

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, an intermediate device in a backhaul mesh for a wireless network receives a registration from an access point of the wireless network in communication with a mobile system. The intermediate device receives a packet that is multicast by a gateway into the backhaul mesh and destined for the mobile system. The intermediate device makes, based on the registration, a determination that the packet should be sent to the access point. The intermediate device sends the packet to the access point for transmittal to the mobile system.

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.

Abstract: Presented herein are techniques to manage a wireless local area network. A method includes defining a plurality of geographical zones corresponding to a geographical area that is serviced by a common service set identifier for a wireless local area network, assigning a pre-shared key to a mobile station based on the plurality of geographical zones, wherein the pre-shared key is associated with predetermined policies for a user of the mobile station, associating a media access control address of the mobile station with the pre-shared key, and controlling access of the mobile station to the wireless local area network based on the predetermined policies.

Abstract: In one embodiment, a method in a multi-tenant wireless network comprises determining a first user private network (UPN) for a first device of a first user. The first UPN provides discovery, by the first device, of other devices on the wireless network to a first subset of other devices on the wireless network. The method further comprises determining a second UPN for the first device of the first user. The second UPN provides discovery, by the first device, of other devices on the wireless network to a second subset of other devices on the wireless network. The method further comprises providing discovery of the first subset and second subset of other devices on the wireless network to the first device of the first user. Discovery of the second subset is provided dynamically based on a current location of the first device.
