Abstract: A signal strength measurement method includes: obtaining, by a first access point (AP), a basic service set identifier (BSSID) of a second AP and a first operating channel, where the first operating channel is an operating channel of the second AP, and a station (STA) is associated with the BSSID of the second AP through the operating channel; and sending, by the first AP, a measurement frame to the STA through the operating channel, where a BSSID value of the measurement frame is the BSSID, the measurement frame indicates the STA to send a measurement response frame of which BS SID value is the BSSID, and the measurement response frame carries a signal strength of the measurement frame measured by the STA.

Abstract: A method and an apparatus for implementing delay measurement. The method includes: determining, by a measurement apparatus, a delay T0 generated when a first packet is transmitted at a first priority over a first loopback path that includes a first sub-path and a second sub-path; determining a delay T1 generated when a second packet is transmitted over a second loopback path that includes the first sub-path, the second sub-path, a third sub-path, and a fourth sub-path, where the second packet is transmitted at the first priority over the first sub-path and the second sub-path and is transmitted at a second priority over the third sub-path and the fourth sub-path; and determining a delay according to T0 and T1. Therefore a delay can be measured only by implementing a measurement function in the measurement apparatus, thereby resolving a problem of complex implementation.

Abstract: A method, an apparatus, and a system for implementing packet loss detection. The method includes: determining, by a detection apparatus, there is no packet loss when packet transmission is performed at a first priority over a first loopback path that includes a first subpath and a second subpath; sending N1 packets over a second loopback path that includes the first subpath, the second subpath, a third subpath, and a fourth subpath, where the packets are transmitted at the first priority over the first subpath and the second subpath, and are transmitted at a second priority over the third subpath and the fourth subpath; and determining a packet loss rate according to N1 and a quantity N2 of received packets returned over the second loopback path. Therefore, a packet loss rate can be detected only by implementing a detection function on a detection apparatus, thereby resolving a problem of complex implementation.

Abstract: Embodiments of this application disclose a device virtualization method applied to an accelerated computing system. The accelerated computing system includes a host end and a device end communicatively connected to the host end. The method may be performed by the device end, or may be performed by a component of the device end (for example, a software configuration module in the device end). The method includes: receiving a management command from the host end, where the management command is used to virtualize a physical resource in the device end to provide a virtual function to the host end for use, and the physical resource is used to perform an accelerated computing task; and configuring a register based on the management command, where the register is configured to virtualize the physical resource.
