摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： In one embodiment, a device identifies a path of travel of a mobile system. The device subdivides the path of travel into a plurality of zones. The device generates time-slotted channel hopping schedules for the plurality of zones, each time-slotted channel hopping schedule having an associated zone among the plurality of zones. The device causes the mobile system to communicate wirelessly with networking infrastructure located along the path of travel, in accordance with a particular one of the time-slotted channel hopping schedules while the mobile system is located in its associated zone.

摘要： In one embodiment, a mobile system scans wireless channels for any upcoming access points using a dedicated monitor radio of the mobile system. The mobile system identifies a particular wireless channel in use by an upcoming access point. The mobile system notifies a second radio of the mobile system of the particular wireless channel. The mobile system performs a handoff between a current access point and the upcoming access point in part by switching the second radio of the mobile system to the particular wireless channel of the upcoming access point.

摘要： 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.

摘要： 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.
