Abstract: This application provides an audio control method, an electronic device, an audio device, and a storage medium. An example method for audio control is applied to an audio device, where the audio device establishes a first Bluetooth connection to a first electronic device, and establishes a second Bluetooth connection to a second electronic device. In the method, in response to determining that a status of the audio device changes, the audio device sends a status notification message to at least one of the first electronic device or the second electronic device, where the status notification message indicates a current status of the audio device.

Abstract: An antenna unit and an antenna array. The antenna unit includes M layers of cross metal patches, M layers of dielectric substrates, and a metal ground layer, where M is an integer greater than 1. In addition, an ith-layer dielectric substrate is disposed between an ith-layer cross metal patch and an (i+1)th-layer cross metal patch. The ith-layer cross metal patch, the ith-layer dielectric substrate, and the (i+1)th-layer cross metal patch are sequentially stacked, and i is an integer ranging from 1 to M−1. An Mth-layer cross metal patch, an Mth-layer dielectric substrate, and the metal ground layer are sequentially stacked. The antenna unit and the antenna array formed by units may have a good polarization feature, a relatively wide operating bandwidth, and a relatively good phase shift feature.

Abstract: This application provides a method for managing a service in an NFV architecture, and an apparatus. The method includes: generating, by a first network element after receiving a network function virtualization NFV resource change notification sent by a virtualized infrastructure manager VIM, first constraint information used to modify NFVI software and/or hardware; and sending, by the first network element, a first notification message to the VIM, where the first notification message carries the first constraint information, and the first constraint information is used by the VIM to modify NFVI software and/or hardware based on the first constraint information.

Abstract: The present disclosure discloses a service migration method including: sending, by a VNFM module, a virtual machine VM request command to a first VIM module, where the first VIM module manages a first host on which post-upgrade new-version software is configured; receiving, by the VNFM module, a VM request response from the first VIM module, where the VM request response includes information about a first VM that the first VIM module requests on the first host, and virtual machine own data that can run on the first host and that is configured by the first VIM module is configured on the first VM; and sending, by the VNFM module, a service migration command to a virtualized network function VNF module, where the service migration command is used to instruct the VNF module to migrate a running service on a second VM to the first VM.

Abstract: The present disclosure provides a method for managing a virtual machine cluster. The method includes: sending, by the first virtual machine, a first heartbeat message to at least two neighboring virtual machines in the N virtual machines, so that the at least two neighboring virtual machines detect the first heartbeat message, where a result of detecting the first heartbeat message is used to determine a status of the first virtual machine, and the first virtual machine establishes a neighbor relationship with the at least two neighboring virtual machines according to the information about the N virtual machines; and detecting, by the first virtual machine as a neighboring virtual machine of a second virtual machine in the at least two virtual machines, a second heartbeat message sent by the second virtual machine.

Abstract: This disclosure provides a memory management method and apparatus, to perform refined management on a process access status in a physical host, a virtual machine, or a container, and a traffic occupation status of each control group (cgroup). The method can includes a first record table corresponding to a target cache page is used to record all cgroups that have read or written target data from or into the target cache page and a quantity of times that the target data is read or written by all the cgroups, to improve accuracy of a traffic statistics result of a cgroup. In this case, throttling is performed on a first cgroup based on an updated first record table, so that throttling on the first cgroup can be more fair and accurate.
