A data processing method and an OpenFlow network are provided. According to the method, after acquiring an aggregation rule from a controller in the OpenFlow network, a switch in the OpenFlow network performs rule matching on to-be-reported data flows according to the aggregation rule. The switch extracts information about data flows matching the aggregation rule in the to-be-reported data flows. Then the switch packetizes and sends the information to the controller, such that the controller determines, according to the information, a forwarding rule for the data flows matching the aggregation rule in the switch. This method avoids that each to-be-reported data flow is sent to the controller using a Packet_In message respectively, such that control channel bandwidth resources consumed by the Packet_In message are reduced. Utilization of the control channel bandwidth resources is improved.
