Service flow aggregation method and device

Embodiments of the invention provide a service flow aggregation method and device. The method comprises the following steps of computing a preset attribute value and traffic of each service flow for the service flows which reach the same source and the same target within the preset time bucket; dividing the service flows with the similarity of the preset attribute values into one group to obtain a pre-divided service flow group, wherein the similarity of the preset attribute values is that the preset attribute values conform to predetermined similar conditions; and respectively carrying out service flow aggregation on each obtained pre-divided service flow group to obtain a target service flow group which is about to make a request for a forwarding path to a controller. In a service flow aggregation process provided by the embodiments of the invention, the preset attribute values of the service flows in each pre-divided service flow group are similar, so that the preset attribute values of the service flows i
