The invention relates to a Goose message flow table filtering method based on an SDN. The Goose message flow table filtering method comprises the steps of (1) configuring the first flow entry of the flow table in a controller, (2) determining whether the first flow entry is configured, (3) configuring the second flow entry of the flow table in the controller, and (4) determining whether the second flow entry is configured. The Goose message flow table filtering method based on the SDN is capable of dynamically configuring the filtering of GOOSE messages based on the flow table of the SDN. The Goose message flow table filtering method is capable of improving the instantaneity of GOOSE message filtering and effectively improving the operation and maintenance efficiency of updating configuration information.
