Abstract: A moving-device fault detection method and system are in the technical field of fault detection. The method includes the steps of collecting a measurement signal of a target device (S10); performing fault type classification on the measurement signal on the basis of an autocorrelation characteristic (S20); on the basis of the classification result, selecting a corresponding fault diagnosis model (S30); and performing fault diagnosis on the basis of the selected fault diagnosis model and the measurement signal to obtain a diagnosis result (S40). On the basis of a fault type distinguishing result, adaptive diagnosis model selection is made to ensure that the selected diagnosis model is a fault detection model suitable for current signal feature rules.

Abstract: A traffic forwarding system that uses a multicast start-of-packet (SOP) pointer to enqueue a multicast packet in packet queues. The system receives cells, assigns pointers to the cells, and stores the received cells in memory. The system assigns multicast SOP pointers to multicast SOP cells. The system reassembles cells into packets and enqueues the packets in packet queues for forwarding. A multicast packet is enqueued in a plurality of packet queues. The memory in which the multicast packet is stored is released after the multicast packet is dequeued from each of the plurality of packet queues.
