Method, apparatus and system for processing data packet

Apparatus for processing a data packet, comprising:

• a processor, configured to match a data packet with match field information of a flow entry;
• the flow entry comprising the match field information and operation field information;
• wherein the operation field information comprises an operation type and first bit field indication information, the first bit field indication information comprises a first offset and a first field length, and the first bit field indication information indicates a first bit field of the data packet, or the match field information comprises second bit field indication information and a match value, the second bit field indication information comprises a second offset and a second field length, and the second bit field indication information indicates a second bit field of the data packet;
• and
• the processor is further configured to perform, if the data packet is successfully matched with the match field information, an operation on the data packet according to the operation field information.

Apparatus for processing a data packet, comprising:

• a processor configured to generate a flow entry addition indication message, the flow entry addition indication message comprising match field information and operation field information;
• wherein the operation field information comprises an operation type and first bit field indication information, the first bit field indication information comprises a first offset and a first field length, and the first bit field indication information indicates a first bit field of the data packet, or the match field information comprises second bit field indication information and a match value, the second bit field indication information comprises a second offset and a second field length, and the second bit field indication information indicates a second bit field of the data packet;
• and
• a network interface, configured to send the flow entry addition indication message to a switching device, to enable the switching device to generate a flow entry according to the flow entry addition indication message and process the data packet according to the flow entry.
