The software OVS can convert the generated flow table rule and write the flow table rule into hardware, and then the data packet is matched with the hardware flow table and is directly forwarded.
In the prior art, the intelligent network card generally implements packet receiving and encapsulating and forwarding or discarding processing on a data packet based on the OVS-DPDK. Specifically, the intelligent network card may generate two flow table rules, an outer-layer flow table and an inner-layer flow table, corresponding to the data packet based on the software OVS, wherein a matching field of the outer-layer flow table is outer information of a packet message, and an action field of the outer-layer flow table is to decapsulate the data packet; the matching domain of the inner layer flow table is an inner layer message corresponding to a target data packet after the data packet is unpacked and a temporary variable generated based on the outer layer message of the data packet, and the action domain of the inner layer flow table is used for forwarding the data packet.
