PFC STORM DETECTION AND PROCESSING METHOD

Provided in the present application is a PFC storm detection and processing method. The method comprises: a first network node performing priority flow control (PFC) detection on a first port queue of a first port, and determining that a first preset condition is satisfied, wherein the first preset condition being satisfied comprises: performing detection within N consecutive first time periods, and during detection within each first time period, the number of first PFC frames sent by the first port queue to a second network node being greater than a first threshold value, and the number of one or more data packets received by the first port queue from the second network node being less than a second threshold value, wherein the first PFC frames are used for instructing the second network node to suspend the sending of all data streams in the first port queue, and N is a positive integer; and the first network node suspending the sending of the first PFC frames from the first port queue to the second network
