A multicast traffic transmission method includes: detecting (S) whether a transmission link between a designed forwarder (DF) and a traffic reception device is abnormal; and when the transmission link between the DF and the traffic reception device is abnormal, sending (S) a first request to a backup designed forwarder (BDF). A packet of the first request includes a protection mark and address information about the traffic reception device, and the first request is used for requesting the BDF to forward traffic to the traffic reception device.

Multicast traffic transmission method, related device and computer-readable storage medium

An industrial visual stethoscope system and a detecting method are provided. The system has a base, a workpiece support, a single-color lighting device, a camera module, a rotating device, and an analyzing device. When the single-color light irradiates the workpiece, if the single-color light irradiates into the crack which is relatively deep and narrow, the single-color light is rarely to be reflected out of the crack. But if the single-color light irradiates into the scar, the single-color light is reflected out of the scar due to the specular reflection. During the relative rotation, when the reflected light enters the camera module in parallel, the energy of the light is concentrated, causing overexposure and forming obvious white light. Thus, the analyzing device can identify the recess is a scar formed by hit rather than a crack formed by heat.
