Abstract: A method is provided in a wireless local area network controller in a wireless communication network. The wireless communication network includes one or more virtual networks identified with virtual network IDs, VNIDs. A request is received from a wireless client to onboard onto the network and the wireless client is mapped to an onboarding VNID. The onboarding VNID is associated with an onboarding virtual network that does not require an authentication of the wireless client. An Internet Protocol address assignment is forwarded to the wireless client. The wireless client is remapped from the onboarding VNID to the destination VNID after authenticating the wireless client. The wireless client maintains the assigned IP address after moving from the onboarding VNID to the destination VNID. Access to the wireless client on a virtual network identified by the destination VNID is provided via the assigned IP address.

Abstract: A user device connected to a wireless network maintains session persistence through a MAC address change of a user device. The user device establishes a multi-path communication session including a first subflow associated with a first MAC address for the user device. When the user device changes from the first MAC address to a second MAC address, the user device establishes a second subflow of the multi-path communication session. The second subflow is associated with the second MAC address. After establishing the second subflow associated with the second MAC address, the user device ends the first subflow associated with the first MAC address.

Abstract: A method includes receiving, at a home controller of a home domain and from a first device in the home domain, a first message concerning a user device that is anchored to the home domain and that has roamed from the home domain to a visitor domain. The method also includes, in response to determining that the first device is a router, opening a tunnel between the home controller and a visitor controller of the visitor domain and communicating the first message to the user device through the tunnel. The method further includes receiving, at the home controller and from a second device in the home domain, a second message concerning the user device and in response to determining that the second device is not a router, communicating, to the second device, a proxy response to the second message.

Abstract: A method for providing multicast frames in a Multi-Dwelling Unit (MDU) is provided herein. An Access Point (AP) can receive a join request from a first client device. The AP can generate a Group Master Key (GMK) from the Pre-Shared Key (PSK) associated with a Basic Service Set (BSS) that includes the first client device. The AP can then derive a Group Transient Key (GTK) from the GMK. The AP may then send the GTK to the first client device. Thereinafter, the AP can send multicast frames to the first client device encrypted by the GTK. The first client device can decrypt the multicast frames with the GTK. However, a second client device, that does not share the PSK, may receive the multicast frame but cannot decrypt the multicast frames.

Abstract: Presented herein are techniques for extending Target Wake Time (TWT) to provide for randomizing and changing media access control (MAC) address (RCM) signaling. According to certain embodiments, a client device operating in a wireless network determines a TWT for the client device. Next, the client device determines that it will change from using a first MAC address to a using second MAC address. Finally, the client device generates, for transmission to an access point device that serves wireless communication in the wireless network, a TWT signaling message. The TWT signaling message indicates the TWT for the client device and the second MAC address.

Abstract: Aspects described herein include a method of automated grouping of client devices for a user-defined network (UDN). The method includes receiving, from a client device an authentication request to join an access provider network. The authentication request includes a unique identifier of the client device for a federation-based network. The method further includes transmitting the unique identifier to a UDN cloud, transmitting the authentication request to an identity provider, and receiving, responsive to the identity provider authenticating the authentication request, a list of one or more UDNs from the UDN cloud that are associated with the unique identifier. The method further includes joining the client device with one or more other client devices present on the access provider network listing a same UDN.

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: The present disclosure is directed to systems and methods that enable automatic provisioning of access points within an enterprise network by a controller of the enterprise network. In one aspect, a method includes detecting, at a network controller, attachment of a first access point to a network; identifying, by the network controller, a profile of a second access point, the second access point having being replaced with the first access point, the profile including at least one of identification parameters and configuration parameters of the second access point; and provisioning, by the network controller, the first access point with the profile of the second access point.
