Abstract
The present disclosure relates to a data flow forwarding abnormality detection method. In one example method, a switching device through which a to-be-detected data flow passes is determined by a controller. At least one flow entry in the switching device that matches the to-be-detected data flow is obtained. The at least one flow entry comprises actual traffic and a match field. The actual traffic is a value of a counter corresponding to the match field. An overdetermined equation set is established based on the actual traffic and theoretical traffic of a data flow in the switching device that matches the match field. Based on the overdetermined equation set, a determination is made on whether the at least one flow entry is abnormal.
