Abstract: Systems, methods, and computer-readable media for controlling link selection and aggregation across multiple wireless networks based on a location of a mobile device. A location of a mobile device in a physical environment can be identified. At least portions of the physical environment can be in wireless range of a first wireless network and a second wireless network. Whether to access network services through either or both the first wireless network and the second wireless network can be determined based on the location of the mobile device in the physical environment. Further, a first interface at the mobile device to the first wireless network and a second interface at the mobile device to the second wireless network can be selectively toggled according to whether it is determined to access the network services through either or both the first wireless network and the second wireless network based on the location.

Abstract: Systems, methods, and computer-readable media for the secure creation of application containers for 5G slices. A MEC application in a MEC layer of a 5G network can be associated with a specific network slice of the 5G network. A backhaul routing policy for the MEC application can be defined based on the association of the MEC application with the specific network slice of the 5G network. Further, a SID for the MEC application that associates the MEC application with a segment routing tunnel through a backhaul of the 5G network can be generated. A MEC layer access policy for the MEC application can be defined based on the SID for the MEC application. As follows, access to the MEC application through the 5G network can be controlled based on both the backhaul routing policy for the MEC application and the MEC layer access policy for the application.

Abstract: Presented herein are techniques for assigning Ultra-Wideband (UWB) anchors for client ranging. A control device can monitor UWB ranging between a mobile device and a primary anchor. In response to determining that a signal strength between the mobile device and the primary anchor is below a threshold, the control device can identify anchors for which the mobile device has had a signal strength above the threshold during a period of time, and select one of the anchors as a new primary anchor for the mobile device. For example, the control device can select the new primary anchor based on a relative collision tolerance mapping for the new primary anchor and at least one other anchor within a UWB range of the new primary anchor. The control device can send a command causing UWB ranging to be performed between the mobile device and the new primary anchor.

Abstract: A method comprising: at a multi-link device (MLD) configured for multi-link operation: establishing a first Internet Protocol (IP) stack of a first IP type and configured with a first IP address of the first IP type, wherein the first IP stack is associated to a first MLD media access control (MAC) address of a first station of the MLD; establishing a second IP stack of a second IP type and configured with a second IP address of the second IP type, wherein the second IP stack exists concurrently with the first IP stack and is associated to a second MLD MAC address of a second station of the MLD; and exchanging, with a peer MLD, IP traffic using one or more of (i) the first IP stack and the first MLD MAC address, and (ii) the second IP stack and the second MLD MAC address.

Abstract: Wireless infrastructure upgrading may be provided. An Access Point (AP) may be caused to decline new association requests received from client devices not associated with the AP. Next, the AP may be caused to instruct client devices associated with the AP that detect a signal level from the AP to be below their roaming margin to roam away from the AP. Then the power of the signal level from the AP may be decreased by a predetermined amount. Causing the AP to instruct client devices associated with the AP that detect the signal level from the AP to be below their roaming margin to roam away from the AP and decreasing the power of the signal level from the AP may be repeated until the power of the signal level from the AP is at a predetermined level.

Abstract: A server that includes a graphics processing unit (GPU) may receive, from a first application that is remote from the server, a first request to reserve a first number of cores of the GPU for a first amount of time. The server may also receive, from a second application that is also remote from the server, a second request to reserve a second number of cores of the GPU for a second amount of time that at least partly overlaps the first amount of time. The server may determine that the first request is associated with a higher priority than the second request and, in response, may reserve the first number of cores for the first amount of time for the first application. The server may send, to the first application, an indication that the first number of cores have been reserved as requested by the first application.

Abstract: Techniques for utilizing a cloud service to compute an end-to-end SLA-aware path using dynamic software-defined cloud interconnect (SDCI) tunnels between a user device and an access point-of-presence (POP) node and inter-POP tunnels of the SDCI. The cloud service may include a performance aware path instantiation (PAPI) component including a POP database for storing performance metrics associated with the POPs of the SDCI, an enterprise policy database for storing user specific policies, and/or a path computation component. The path computation component may compute the path, based on the user specific policies, performance metrics associated with the POP nodes, and/or real-time contextual data associated with the user device and/or destination device. The path may include a first tunnel between the user device and the most optimal access POP node of the SDCI and a second tunnel between the access POP node, through the internal POP nodes, and to the destination device.

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.

Abstract: A method includes estimating distances between a user device and an access point based on a series of FTM ranging bursts exchanged between the user device and the access point. The method also includes calculating a variance of the estimated distances and in response to determining that the variance exceeds a threshold, instructing the user device to perform an action that reduces the variance. Other embodiments include a device that performs this method.
