Abstract: A user device connected to a wireless network maintains session persistence through a MAC address change of a user device. The user device establishes a multi-path communication session including a first subflow associated with a first MAC address for the user device. When the user device changes from the first MAC address to a second MAC address, the user device establishes a second subflow of the multi-path communication session. The second subflow is associated with the second MAC address. After establishing the second subflow associated with the second MAC address, the user device ends the first subflow associated with the first 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: A first access point of a wireless network minimizes Media Access Control (MAC) address collisions in the wireless network. The first access point receives an association request from a first wireless device. The association request identifies a first MAC address of the first wireless device. The first access point determines whether a second wireless device is associated with the wireless network using the first MAC address. Responsive to a determination that the second wireless device is associated with a second access point of the wireless network, the first access point obtains a virtual MAC address for the first wireless device. The first access point translates between the first MAC address and the virtual MAC address for network traffic of the first wireless device.

Abstract: The present technology is directed to visualizing a Wi-Fi access point radio frequency (RF) propagation pattern based on telemetry data over time. The present technology can receive telemetry data for a Wi-Fi network of a building plan in a Wi-Fi visualization system, store the telemetry data with a timestamp, determine a RF propagation pattern in a 3-D space for at least one Wi-Fi access point in the Wi-Fi network, present a user interface including a time slider to facilitate manipulation of a time axis between the first timestamp and the second timestamp, and present a visualization of the RF propagation pattern based on an indication of the time slider.

Abstract: A wireless client device communicates, to an access point over a secure channel, a mapping of a dynamic device address to a stable device address. By communicating the mapping, the access point is able to determine that packets received from two different device addresses originate from a common device. The access point is then able to maintain an association between the originating device and other network resources assigned or allocated to the originating device, such as IP addresses or infrastructure station address, which is used to identify the originating device to other devices outside the network in some embodiments.

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: Location tracking consent management may be provided. A zone in a network may be configured with a corresponding tracking type. Next a computing device associated with the zone may be enabled to transmit an information element indicating the tracking type configured for the zone. A client device may then be allowed to disallow tracking of the client device based on the tracking type.

Abstract: Disclosed are systems, apparatuses, methods, and computer-readable media for extending and standardizing heterogeneous network devices using instrumentation. A method includes: receiving, by a client device using a first network interface, instrumentation bytecode to supplement with a data link layer from a management device, wherein a verifier of the client device verifies that the instructions of the bytecode are constrained for security based on a plurality of rules; in response to detecting a trigger at the client device, executing the instrumentation bytecode at the client device to perform at least one function associated with the trigger; and sending a response from the client device based on an execution result of the instrumentation bytecode.
