Abstract: Parallel Redundancy Protocol (PRP) using non-overlapping Resource Unit (RU) groupings may be provided. A first computing device may associate to a first Access Point (AP) at a virtual Media Access Control (MAC) address. Next, the first computing device may associate to a second AP at the virtual MAC address. Then data from a data frame may be replicated to a first one or more RUs in a channel. The first one or more RUs may be assigned to the first AP. Data from the data frame may then be replicated to a second one or more RUs in the channel. The second one or more RUs may be assigned to the second AP and may not overlap the first one or more RUs.

Abstract: Aspects of the disclosure include a method and associated network device. The method includes authenticating an identity of a user of a client device after the client device is associated with an access network provider. Authenticating the identity of the user comprises receiving, from an identity provider, a credential associated with the identity, and receiving, from the identity provider, information identifying a network-based service to be applied to network traffic with the client device. The method further includes establishing, using the credential and the received information, a secure connection between the access network provider and a service provider that is capable of providing the network-based service. The method further includes receiving network traffic from the service provider. Packets of the network traffic include an assurance value that enables the client device to determine that the network-based service is being provided by the service provider.

Abstract: Spurious beamforming in high density environments can be reduced via transmitting a first signal from a first Access Point (AP) to a first endpoint associated with the first AP via a first beamforming arrangement; in response to identifying that the first beamforming arrangement is pollutive to a second endpoint associated with a second AP: deprecating the first beamforming arrangement; and transmitting a second signal from the first AP to the first endpoint via a second beamforming arrangement, different from the first beamforming arrangement.

Abstract: A method and system for implementing security policies for a user device based on one or more user device parameters. When a user device joins a domain, the security policy agent determines one or more security policies for the user device based on one or more parameters of the user device. The user parameters may include the type of user device, a user group, an application to be used, etc. The security polies are sent to the user device. The user device generates a data packet having metadata indicating the one or more device parameters. The data packet is sent to a remote security service where security policies are implemented based on the metadata.

Abstract: Rotation of a wireless client device address is based on an encryption key and a nonce value. Key information and nonce value information are shared between a wireless client device and a network infrastructure component over a secure communication channel. The wireless client device encrypts the nonce value using the key information and encodes the encrypted value as a device address. The wireless client device then identifies itself via a source address value in a message transmitted over a wireless network. Upon receiving the message, the network infrastructure component decrypts information derived from the source address value and compares the resulting data to the nonce value. If a match is identified, the network infrastructure identifies the wireless client device as a source of the message. In some embodiments, the nonce value is updated with each rotation to provide for improved entropy of generated device addresses.

Abstract: Embodiments for virtual reality (VR) and augmented reality (AR) scenes updates at VR/AR devices in a network are described. Network traffic for the scene updates is divided into traffic layers such as coarse grain (CG) layer traffic and a fine grain (FG) layer traffic for a give VR/AR scene update. The CG layer traffic is scheduled first in resource units (RUs) of a plurality a transmission opportunity (TXOP) for a VR device and FG layer traffic is scheduled in remaining RUs during the TXOP to provide synchronous viewing experiences to users of the VR/AR devices.

Abstract: Automated activation of unsolicited probe responses may be provided. Probe traffic data may be received. Then, based on the probe traffic data, a plurality of probe traffic cost metrics may be determined. Each one of the plurality of probe traffic cost metrics may be respectively associated with a plurality of Unsolicited Probe Response (UPR) modes. An Access Point (AP) may then be operated in a one of the plurality of UPR modes that has a respective probe traffic cost metric that indicates a lowest probe traffic cost of the plurality of probe traffic cost metrics.
