Abstract: A data packet processing method, Where the method includes matching a received data packet in a flow table, and determining the received data packet as a newly-established data packet, where the newly-established data packet is a data packet that needs to be reported to a controller to determine a processing manner, determining a target priority of the newly-established data packet, and reporting the newly-established data packet to the controller according to the target priority. Priorities of data packets entering an OPENFLOW switch are determined, and for unsuccessfully matched data packets, a data packet having a high priority is forwarded preferentially according to the priorities, thereby ensuring that data having a high priority is not discarded.

Abstract: A data reading method, a data processing device, and a data processing system are provided. The method, executed by a first control node, includes receiving a reading message forwarded by a data switching device, where the reading message is used to instruct the first control node to read first data, and the reading message is sent by a second control node to the data switching device; if a data status identifier of the first data in a first storage node is a valid identifier, reading the first data from the first storage node, and sending the read first data to the data switching device, so that the data switching device forwards the read first data to the second control node, where the valid identifier indicates that the first data on the first storage node is available. The present application ensures that the latest first data in the node group is read.
