The method comprises: when interaction is performed between a controller and a switch, the controller and the switch carrying a TraceID in an initiated OpenFlow message; and when the controller or the switch receives the OpenFlow message carrying the TraceID, carrying a same TraceID in a response message of the OpenFlow message or another message triggered by the OpenFlow message.
