Abstract: Methods and systems are described herein for detecting deviations from an expected power profile of a device. The method comprises: retrieving a manufacturer usage description (MUD) associated with the device. The MUD includes a power profile associated with the device. An expected power consumption parameter can be determined from the power profile. The method may further comprise monitoring an actual power consumption parameter of the device and comparing the expected power consumption parameter to the actual power consumption parameter. The method may further comprise determining a deviation between the power consumption parameter and the expected power consumption indicated in the power profile, and outputting a notification when the deviation is equal to or greater than a threshold value.

Abstract: In one embodiment, a device registers with a controller for a mesh of overhead access points. The device receives, from the controller, a communication schedule for the device. The device generates a message to be sent to the mesh of overhead access points. The device transmits, according to the communication schedule, the message as a beam cone directed substantially upward relative to the device towards the mesh of overhead access points. The message is received and relayed by one or more particular access points in the mesh without the device previously performing a wireless association exchange with those one or more particular access points.

Abstract: A wireless client device communicates, to an access point over a secure channel, a mapping of a dynamic device address to a stable device address. By communicating the mapping, the access point is able to determine that packets received from two different device addresses originate from a common device. The access point is then able to maintain an association between the originating device and other network resources assigned or allocated to the originating device, such as IP addresses or infrastructure station address, which is used to identify the originating device to other devices outside the network in some embodiments.

Abstract: A method for establishing a VPN with a client device is provided. In the method, an AP can receive an access request directed to an OpenRoaming (OR) Service Set Identifier (SSID) from the client device. The AP can send the access request to an OR connector. In response to the access request, the AP may receive an access response from the OR connector. The access response can include an attribute indicating an address to connect to a company Virtual Private Network (VPN) headend. The AP may then use the attribute to establish the VPN connection with the company VPN headend.

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: 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.
