Abstract: Embodiments of this application provide a resource preemption method, an apparatus, and a system, to reduce a quantity of times of frequent resource preemption, and improve resource security. In one example, a first terminal device obtains a first time interval and a second time interval, and preempts or determines not to preempt a first resource according to a first preset rule. The first resource is a resource reserved by a second terminal device or a resource reserved for a first service to be transmitted by the first terminal device. The first time interval is a time interval related to the first resource. The second time interval is used to indicate a preemption forbidden time. The first preset rule is determined based on the first time interval and the second time interval.

Abstract: Embodiments of this specification provide a method and a system for performing service verification on a plurality of parties in federated computation based on a container cluster. In the verification method, a verification management center sends a task establishment request to a master node in response to a service verification request of a user, where the task establishment request indicates at least a target service that is to be verified and that is used by a target participant.

The target slave node provides the service verification result for the verification management center.

Abstract: Systems, apparatus, and methods for “fast” wake-up using virtualized addresses. Action cameras need to conserve power most of the time, but also be immediately responsive to catch action when it happens. Unfortunately, most general-purpose operating systems (e.g., Linux-based) lock up the processor during boot-up. Empirically, an OS boot process might take between 6-7 seconds from start to finish, even in highly streamlined boot sequences. This is undesirable, especially where one device (e.g., a smart phone) triggers an action camera to capture an image. Various embodiments of the present disclosure create “virtual action addresses” that directly expose interrupts as addressable space (via a Bluetooth Low Energy (BLE) network). In one such example, the interrupts trigger a capture or other action. The action camera can immediately service the interrupts with its real-time operating system (RTOS) while the general-purpose OS is booting up.
