Provided are a flow table modifying method, a flow table modifying device, and an OpenFlow network system. The method comprises the following steps: a switch receives a modify flow entry message transmitted by a controller; the switch searches a flow table corresponding to a flow table identifier for the presence or absence of a flow entry matching to-be-modified target information; and, if a flow entry matching the to-be-modified target information is present, the switch modifies a matching domain field of the matching flow entry to a new matching domain field. The method is low in information redundancy and high in efficiency and reduces interface load. |
