Abstract: In one embodiment, a management service for a network that is executed by one or more devices establishes a trust relationship with an entity associated with an endpoint in the network. The management service receives, via a Manufacturer Usage Description (MUD) file for the endpoint, an indication that the entity desires remote access to the endpoint in the network. The management service configures, based on the indication, the network to provide a remote access connection between the entity and the endpoint in the network. The management service provides, to the entity, credentials to the entity for the remote access connection.

Abstract: Techniques and apparatus for determining quality of experience (QoE) for wireless communications are described. One technique involves transmitting a QoE support message to an access point (AP) within an access network. The QoE support message queries whether the AP supports providing key performance indicators (KPI(s)) indicative of QoE provided by the access network. An indication of whether the AP supports providing the KPI(s) is received in response to the QoE support message. The KPI(s) are received when the AP supports providing the KPI(s). A determination is made whether to communicate with the AP based at least in part on the KPI(s). Communications are then performed in accordance with the determination.

Abstract: The present disclosure is related to dynamic methods of managing roaming of client devices at boundaries of area serviced by access points. In one aspect, a method includes estimating by a controller, first signal information of a signal transmitted by an access point and received at a client device, the first signal information being from the perspective of the access point, the client device operating at a boundary of an area serviced by the access point; determining, by the controller, second signal information for the signal, the second signal information being from the perspective of the client device; and performing, by the controller, roaming management of the client device based on the first signal information and the second signal information.

Abstract: Device-to-Device (D2D) communications in hybrid networks are provided by identifying a first dual-mode endpoint seeking to communicate with a second dual-mode endpoint via a D2D communications session; identifying a first communications pattern of network resource usage for the first Radio Access Technology (RAT) and a second communications pattern of network resource usage for the second RAT in the heterogeneous wireless network environment; assigning the D2D communications session to the first RAT based on the first communication pattern and the second communication pattern; and in response to detecting network resource usage changes in the first RAT, transitioning the D2D communications session to the second RAT. In some embodiments, the D2D communications session is assigned to the first RAT using a shared frequency regulated by a band access controller that is reserved as a static resource for D2D communication while high-priority signals are absent from the shared frequency.

Abstract: Presented herein are infrastructure triggering techniques for secure Ultra-Wideband (UWB) ranging. In one example, a method may include providing UWB ranging parameters to a mobile device via a first radio communication, wherein the first radio communication is a non-UWB radio communication; and triggering the mobile device to perform UWB ranging with a UWB anchor, wherein the triggering is performed using a second radio communication. In another example, a method may include, obtaining, by a mobile device, UWB ranging parameters for a geographic area; obtaining a UWB ranging instruction for the geographic area; and performing UWB ranging with a target UWB anchor based on the UWB ranging parameters and the UWB ranging instruction.

Abstract: Improved mesh performance using Overlapping Basic Service Set (OBSS) coloring and transmission scheduling may be provided. A controller may determine that a plurality of Access Points (APs) in a mesh network each have a Received Signal Strength Indicator (RSSI) that is in a predetermined range. Next, the controller may assign, in response to determining that the plurality of APs each have the RSSI that is in the predetermined range, OBSS colors to links between the plurality of APs to limit packet collision in the mesh network between the plurality of APs. The controller may then create a transmission schedule for transmissions between the plurality of APs in the mesh network based on the assigned OBSS colors.

Abstract: In one embodiment, a method comprises: classifying, by a controller device, a first access point device in a WLAN as a leader access point for a wireless client device, and at least a second access point device as a follower access point; and allocating, to the leader access point, a shortened medium access control layer timer (“timer”) that is shorter than a prescribed timer used by the follower access point, the shortened timer causing the leader access point to respond to reception of a wireless data packet from the wireless client device by transmitting an acknowledgment to the wireless client device upon expiration of the shortened timer; the prescribed timer causing the follower access point to defer to the leader access point based on the follower access point waiting for at least expiration of the prescribed timer before selectively transmitting a corresponding acknowledgment in response to receiving the wireless data packet.

Abstract: This disclosure describes dynamically placing workloads using cloud service energy efficiency. The techniques include obtaining energy efficiency metrics (EEMs) that indicate the carbon footprint for different data centers of cloud service providers. In some configurations, an Energy Efficiency Quotient (EEQ) may be generated by an Energy Telemetry Engine (ETE) that indicates the energy efficiency for each data center/Point of Presence (POP) where a workload may be migrated/hosted. The ETE can be used to rank the different host locations (e.g., different data according to their EEQ. In some examples, one or more other metrics (e.g., latency, bandwidth, . . . ) may be used to identify any POPs that do not meet specified conditions (e.g., latency constraints, bandwidth constraints, . . . ). When a suitable host location is determined (e.g. a POP meets both the performance and EEQ specifications), the workload may be placed onto one or more resources of the selected data center.

Abstract: This technology allows time synchronization in wireless networks with mobile stations. A wireless network controller transmits instructions to access points (“APs”) within the wireless network to monitor transmissions for time synchronization. One or more second APs observe fine time measurement (“FTM”) exchanges between a first AP and a mobile station. A particular second AP determines whether to perform a time synchronization with the first AP based on the detection of the FTM exchange or a determination that the station is moving toward the second AP. For time synchronization, the second AP determines the time that the first AP transmitted the FTM exchange and the time of transmission from the first AP to the second AP. The second AP synchronizes a second AP clock to the summation of the time of the transmission of the FTM exchange and the time of transmission from the first AP to the second AP.
