Abstract: Embodiments of the present invention relate to the field of communications technologies and disclose a packet loss detection method, an apparatus, and a system. The method includes: collecting, by a first network device according to packets sent to a second network device, statistics on a first result corresponding to each group of packets, one first result includes a quantity of packets in one group of packets and a section identifier of the group of packets, each group of packets includes multiple packets, and multiple packets are continuously sent by first network device and belong to a section corresponding to a section identifier of the group of packet; sending, by first network device, first result corresponding to each group of packets to a controller according to a preset rule, so that controller determines whether a packet in the packets sent by first network device to second network device is lost.

Abstract: The present disclosure relates to priority flow control (PFC) storm detection and processing methods. In one example method, a first network node performs PFC detection on a first port queue of a first port, and determines that a first preset condition is met. The first preset condition includes: detection is performed in N consecutive first time segments, when the detection is performed in each first time segment, a quantity of first PFC frames sent by the first port queue to a second network node is greater than a first threshold, and a quantity of one or more data packets received by the first port queue from the second network node is less than a second threshold. The first PFC frame is used to indicate the second network node to suspend sending all data flows in the first port queue, and N is a positive integer.
