Abstract: Dynamic application QoS profile provisioning may be provided. First, an access point may send a profile to a client device. The profile may comprise a plurality of application identifiers and a plurality policies corresponding to the plurality of application identifiers. Each of the plurality of application identifiers may respectively correspond to a plurality of applications. Next, the client device may receive the profile. Then the client device may select, from the received profile, a first policy from the plurality policies in the profile. The first policy may correspond to a first application identifier in the plurality of application identifiers. The first application identifier may correspond to a first application within the plurality of applications. The first application may be on the client device. The first application on the client device may then create a network flow from the client device to the access point based on the selected first policy.

Abstract: In one embodiment, a gateway to a Layer-3 network forms a first Layer-2 tunnel between the gateway and a first wireless access point (AP) that communicates wirelessly with a first mobile node of a mobile system (MS) via a first wireless connection. The gateway generates a mapping that associates an onboard device of the MS with the first AP and an identifier for the MS, based on traffic conveyed via the first Layer-2 tunnel and associated with the onboard device, the traffic comprising a header that indicates the identifier for the MS. The gateway receives, from a second AP, an indication that the MS is roaming from the first wireless connection to a second wireless connection, the indication including the identifier for the MS. The gateway updates the mapping to associate the onboard device of the MS with a second AP, based on the indication that the MS is roaming.

Abstract: Techniques are provided that rotate a device address used to identify a wireless client device on a wireless network. The wireless client device and at least one network infrastructure component identify a plurality of device addresses associated with the wireless client device. In some embodiments, the plurality of device addresses are generated via a corresponding plurality of invocations of a stateful random number generator, such as a cryptographically secure pseudorandom number generator.

Abstract: A Radio Access Network (RAN) element provides an internet indication to a User Equipment (UE) to enable the UE to quickly obtain internet access. The RAN element determines that the RAN element is connected to at least one gateway that provides public internet access, and broadcasts an internet indication. The RAN element determines that the UE has requested public internet access via the RAN element and provides the UE with public internet access.

Abstract: In one embodiment, a device identifies a plurality of access points of a wireless network. The device also identifies a plurality of mobile nodes of a mobile system. The device establishes a first label-switched path in the wireless network that comprises a wireless link between a first mobile node in the plurality of mobile nodes and a first access point in the plurality of access points. The device establishes a second label-switched path in the wireless network that comprises a wireless link between a second mobile node of the mobile system and a second access point in the plurality of access points.

Abstract: Systems, methods, and computer-readable media are provided for an efficient roaming management method using a single association identifier token for associating with different access points. In one aspect of the present disclosure, a network controller includes memory having computer-readable instructions stored therein and one or more processors. The one or more processors are configured to execute the computer-readable instructions to receive a request from an endpoint to connect to a first access point; generate association identification token (e.g., PMK and PMKID) for the endpoint to connect to the first access point; and distribute the association identification token to a second access point prior to the endpoint attempting to connect to the second access point, the association identification token being used by the second access point to validate a subsequent request by the endpoint to connect to the second access point.

Abstract: A wireless network environment includes a plurality of access points, a wireless local area network (WLAN) controller, and a plurality of client devices. The client devices attempt to authenticate with the WLAN controller to gain access to wireless services provided by the WLAN controller and/or the access points. To authenticate with the WLAN controller, the WLAN controller obtains a request to establish a wireless network connection from one or more of the client devices. The WLAN controller then provides a response to the request. The response indicates whether the WLAN controller supports performing password-mapped simultaneous authentication of equals (SAE). The WLAN controller then obtains a message including a password-mapped identifier from the client device. The WLAN controller then establishes a connection with the client device based on the password obtained with password-mapped identifier mapping at WLC.

Abstract: Methods are provided for extending sponsored Wi-Fi guest access capability to other enterprise tools and/or access technologies such as private access networks including private LTE and 5G networks. The methods include a controller detecting a user equipment (UE) that is connected to a guest access service provided by a wireless local access network (WLAN) and generating a profile for the guest access service. The methods further include the controller providing, to the UE, the profile to cause the UE to connect to the guest access service provided by another access network.
