Abstract: This application relates to the wireless communications field and provides a frame transmission method, device, and system. The method includes: sending, by a second device, n wake-up frames to a first device, where the n wake-up frames each carry segmented content of wake-up signaling, so that a wake-up receiver of the first device wakes up a main transceiver of the first device based on the n wake-up frames, and after being woken up, the main transceiver sends, to the second device, a response frame used to indicate whether the n wake-up frames are correctly received.

Abstract: The present disclosure relates to a slice monitor for monitoring slices programmed by a slice owner and deployed by an orchestrator in the control and data planes of a communication network. The slice monitor comprises multiple databases containing different types of information, selects the probes to monitor each slice in the control plane or the data plane and instantiates the selected probes as well as a single-slice monitoring device specific to each slice. For optimization, the slice monitor configures the content of its databases by communicating through multiple interfaces with different actors such as the slice owner, the owner of the orchestrator and the owner of itself. Using alarm handlers and a reconfiguration engine, the slice monitor together with the single-slice monitoring device can detect and compensate for possible violations in the service-level agreement by reconfiguring the slice. If the compensation fails, the slice monitor requests the orchestrator for reconfiguration.

Abstract: A method and apparatus for indicating occupation of resources through an indication channel, and a storage medium. The method includes, through pre-configuring, a time domain indication and a frequency domain indication for indicating the occupation of the second service resources by the first service through an indication channel. As few K+S bits as possible indicate a position for the transmission of the first service, the duration of the first service, and resource occupation by the first service in the frequency domain. This reduces the impact of the first service on the second service and the overhead of the indication channel for the transmission of the first service while ensuring the transmission of the first service.

Abstract: A local network device of a network switching system determines, based on a first set of received packets that contain markings indicating congestion at one or more other network devices in the network switching system, one or more respective congestion levels of one or more network paths through the network switching system.
