Abstract: This application claims to protect an active in-situ flow metrics method, a network device, and a system. The method includes: In a detection domain to which in-situ flow metrics are applied, the head node actively generates a detection packet including in-situ flow metrics information and an analog service packet. After receiving the detection packet sent by the head node, the end node detects network performance based on the in-situ flow metrics information carried in the detection packet, terminates the detection packet, and does not continue to forward the detection packet. In the method in this application, an in-situ flow metrics protocol is extended to add an active in-situ flow metrics capability, so that in-situ flow metrics are implemented even when there is no real service traffic, thereby covering various scenarios of network performance detection.
