Abstract: Techniques to adaptively support/enable a wireless network feature for certain wireless client devices without hampering the performance or connectivity of wireless client devices which do not support that wireless network feature. An access point or wireless network controller adaptively enables a wireless network feature without advertising support for the wireless network feature in a wireless network-standard compliant manner to allow one or more wireless clients that support the wireless network feature to use the wireless network feature when associated to the access point while enabling association of one or more wireless clients that do not support the wireless network feature.

Abstract: Techniques for a Software-Defined Networking (SDN) controller associated with a multisite network to implement jurisdictional data sovereignty polices in a multisite network, route network traffic flows between user sites and destination services over one or more provider sites, and/or perform a routing operation on the network traffic flow(s) based on the jurisdictional data sovereignty policies. The jurisdictional data sovereignty polices may be implemented using destination group tags (DGTs) and/or source group tags (SGTs). A secure access service edge (SASE) associated with the network controller may generate, store, and distribute the DGTs to provider sites and/or the SGTs to user sites. Based on the SGT and/or DGT associated with a network traffic flow, one or more services may be applied to the network traffic flow, and the network traffic flow may be routed through a particular region of a software-defined access (SDA) transit.

Abstract: Methods are provided in which a collaboration server connects at least two participants via respective user devices to a collaboration session. The collaboration server further distributes, to the respective user devices, media stream data and one or more customized graphical items that are distinguishably displayed in the collaboration session. The one or more customized graphical items are displayed in a foreground or a background associated with a collaboration space of first participant of the at least two participants. The collaboration server further detects a selection, by one of the respective user devices, of a graphical item from the one or more customized graphical items displayed in the collaboration space and performs at least one action associated with the graphical item during the collaboration session based on detecting the selection of the graphical item.

Abstract: In one embodiment, a control tower device obtains, first state information from sensing or reporting systems or devices at a particular location via a first communication channel. The control tower device makes, based on the first state information, an evaluation regarding the particular location using one or more digital twins representing one or more entities of the particular location. The control tower device obtains second state information from one or more trusted verifiers for the particular location via a second communication channel. The control tower device verifies, based on the second state information, the evaluation regarding the particular location.

Abstract: In one embodiment, a method for achieving zero packet loss in wireless roaming is implemented by a processor of a wireless client device in a system. The wireless client device establishes a first data plane in association with a first radio connected to a first access point and a second data plane in association with a second radio. The first data plane is different from and operates concurrently with the second data plane. The wireless client device determines a second access point by scanning a plurality of operating channels using the second radio. The wireless client device synchronizes the second data plane with a network controller to connect the second radio with the second data plane to the second access point. The wireless client device switches traffic of the first data plane connected to the first access point to the second data plane connected to the second access point.

Abstract: A Radio Access Network (RAN) node configures a User Equipment (UE) to provide measurement results for private wireless networks in the neighborhood of the UE. The RAN node registers the UE with a computer network and provides location information about the UE to an Application Function (AF) connected to the computer network. The RAN node obtains a partial identifier that specifies a range of private wireless networks selected by the AF, and sends a request to the UE for measurements associated with the range of private wireless networks.

Abstract: The present disclosure describes systems and methods for associating a client device with an edge server. The method includes receiving by each of a plurality of cloud servers a signal from a client device requesting a resource provided by the plurality of cloud servers. Each of the cloud servers then calculates a distance between each cloud server and the client device, and an approximate location of the client device may be determined based on the calculated distance and the known location of the cloud servers. Using the approximate location of the client device, at least one of a plurality of edge servers that are located within a predetermined distance of the client device is identified by the cloud server, and the cloud server or client device may choose one of the identified edge servers through which the client device may be associated to communicate with the cloud server.

Abstract: In one embodiment, a method may access a plurality of Industrial Internet of Things (IIoT) devices within a network. The method may determine a shared risk model associated with the plurality of IIoT devices within the network. The method may determine, using the shared risk model, a shared risk value for each of the plurality of IIoT devices within the network. The method may determine, using the shared risk model, a plurality of associated clusters of IIoT devices within the network based on the shared risk value for each of the plurality of IIoT devices within the network. The method may determine an associated risk minimization for each of the plurality of IIoT devices within the network based on the plurality of associated clusters of IIoT devices within the network and the shared risk value for each of the plurality of IIoT devices within the network.
