摘要： Methods and systems of segmenting computing devices in a wireless network having an access point broadcasting in a single domain are described. In an exemplary method, a request to join the wireless network is received from a computing device. The request is associated with an identifier. When the identifier is not associated with a virtual network within the wireless network, a virtual network is configured within the wireless network and the identifier is associated thereto and the computing device is assigned thereto. When the identifier is associated with an existing virtual network within the wireless network, the computing device is assigned to the existing virtual network.

摘要： In some examples, a headless device that is without an available user interface and that is to be provisioned for access to a network receives information relating to provisioning of the headless device from a network node. The headless device sends, to a mediator device with a user interface, at least a portion of the received information. The headless device receives, from the mediator device, information to proceed with the provisioning of the headless device.

摘要： An access point advertises a management frame quality of service (MFQ) policy that defines an access category used for transmitting a first type of management frame. Each mobile station associated with the access point is to prioritize transmission of management frames according to the MFQ policy advertised by the access point, unless a policy configuration request for the mobile station to prioritize transmission of management frames according to a different MFQ policy has been accepted.

摘要： In some examples, a configurator device maps a configuration attribute received from a wireless device to a credential attribute, the credential attribute to be mapped to a network policy. The configurator device sends the credential attribute to the wireless device, the credential attribute useable by the wireless device to access an access point (AP), and useable by the AP to obtain the network policy to apply to a communication of the wireless device.

摘要： In some examples, a source device categorizes a plurality of messages for transmission to a recipient device, the plurality of messages comprising vehicle-related information. Based on the categorizing, the source device identifies selected messages of the plurality of messages to be aggregated. The source device aggregates the selected messages into a single transmission from the source device to the recipient device.
