    Abstract: Techniques and apparatus for configuring ultra-wideband (UWB) communications using out-of-band (OOB) mechanisms are described. An example technique performed by a wireless device includes obtaining, prior to association with an access point (AP), ultra-wideband (UWB) information from the AP via an out-of-band (OOB) communication link between the wireless device and the AP. A location server within a network including the wireless device and the AP is determined based on the UWB information. Configuration information associated with a UWB ranging session from the location server is obtained via the OOB communication link. The UWB ranging session is performed in accordance with the configuration information.

    Abstract: Network traffic interference detection and management may be provided. An infringement event by an infringing Access Point (AP) on a Restricted Target Wake Time (rTWT) transmission opportunity (TxOp) associated with a victim AP may be detected, and information associated with the infringement event may be added to an infringement list, wherein the information includes a MAC address associated with the infringing AP. A controller, may receive the infringement list and notify the infringement event to the infringing AP. The infringing AP may determine whether a transmission associated with the infringement event is low latency and high priority. When the transmission is not low latency and high priority the infringing AP may modify future transmissions based on the notification. When the transmission is low latency and high priority the infringing AP may notify the controller that the transmission is low latency and high priority. The controller may then create a negotiation between the victim AP and the infringing AP, wherein the negotiation comprises managing future transmissions of the victim AP and the infringing AP.

    Abstract: Devices, systems, methods, and processes for feature level power calibration are described herein. Network devices include sensors that generate sensor readings indicative of various device parameters. A calibration logic utilizes the sensor readings and feature permutations associated with the sensor readings to predict a feature level power consumption for all features of the network device. The calibration logic then applies a calibration factor to the predicted feature level power consumption and obtains an actual feature level power consumption. Using the actual feature level power consumption, the calibration logic determines an actual power consumption for feature licenses of the network device. The feature and feature license level power consumption is utilized for determining which features or feature licenses can be deactivated when the device power consumption is outside a threshold limit. Such dynamic deactivation ensures that the network device accurately meets the sustainability goals.

    Abstract: Techniques and architecture are described for L2 service insertion in a network. More particularly, the techniques and architecture provide for monitoring a L2 service, e.g., firewall, MAC address (instead of learning the MAC address) and registering/de-registering the service node (e.g., fabric border or edge or LISP service_etr) to the service control plane (e.g., LISP MSMR) based on this. This not only load-balances the traffic (per L2 flow) but also tracks it for node's liveliness. The techniques and architecture also provide L2 service insertion connected to a service border to allow for dynamic SGT based service, e.g., firewall, insertion for both software defined access (SDA) fabric and non-fabric deployments.

    Abstract: A method for identifying one or more weakness in a network system through simulations includes configuring a plurality of chaos events to be run on the network system, running the plurality of chaos events on the network system, receiving alert messages from a monitoring system, determining differences if the alert messages match with a set of expected alert messages and/or delay in receiving the alert messages, and reporting the determined differences to a control plane of the network system for display on a user terminal.

    Abstract: In one aspect, a system includes a station device configured to transmit a signal; multiple access point devices in connection with the station device, the multiple access point devices configured to receive the signal transmitted from the station device, wherein the multiple access point devices are configured to convert the signal into a measurable form; and a processing unit operably connected to the multiple access point devices. The processing unit is configured to, for each subcarrier within the signal received by the multiple access point devices, determine a measurement of channel state information including an overall shape of the signal; determine a magnitude distance for each subcarrier; and determine a location of the station device based on a fit of the magnitude distance to a model, wherein the model is based on an environment with one or more obstacles causing an obscuration of the signal.
