Abstract: The present application discloses a network device, a method for security and a computer readable storage medium. The example network device may include a processor to perform: acquiring data to be processed from a downstream device, and transmitting it to a trusted platform module (TPM); and after the TPM encrypts the data to be processed using a cloud key stored therein, receiving the encrypted data for subsequent usage. The processor is further to perform: sending a request to a remote server to acquire the cloud key; and forwarding the acquired cloud key to the TPM for storage.

Abstract: An example method of controlling a wireless access point may include associating accumulated-channel-resource-consumption variables with, respectively, resource consumers of the wireless access point. The method may further include, for wireless communications of the wireless access point determining a number of spatial streams effectively consumed by the respective wireless communication; determining an operational bandwidth effectively consumed by the respective wireless communication; determining a duration of the respective wireless communication; determining a channel-resource-consumption amount for the respective wireless communication based on the number of spatial streams effectively consumed by the respective wireless communication, the operational bandwidth effectively consumed by the respective wireless communication, and the duration of the respective wireless communication; and determining values for the accumulated-channel-resource-consumption variables by accumulating the channel-resource-consumption amounts per resource consumer. The method may further include determining whether to impose channel access restrictions on the resource consumers based on their respective accumulated-channel-resource-consumption variables.

Abstract: In one example a computer implemented method comprises receiving, at an access point of a wireless network, a multicast/broadcast frame which identifies one or more stations associated with the access point as a recipient for the multicast/broadcast frame, and in response to a determination that at least one station of the one or more stations identified as a recipient for the multicast/broadcast frame is in an inactive state, determining a beacon slot time for a transmission of the multicast/broadcast frame from the access point, in response to a determination that at least one of the one or more stations in an inactive state will miss the beacon signal, converting the multicast/broadcast frame to a unicast frame, and holding a copy of the unicast frame to be transmitted to the at least one of the one or more stations in an inactive state that will miss the beacon signal.

Abstract: An example of controlling a network of wireless access points (APs) to detect that a client device associated with the network is stationary in an AP-overlap area, and in response to the detection that the client device is stationary in the AP-overlap area, assigning one of the APs to be a preferred AP for the client device. The APs are to avoid connecting with any client devices that have been assigned another AP as a preferred AP. Thus, the stationary client device in the overlap area may be prevented from undesired roaming.
