Hardware-assisted acceleration method and device for network flow

The invention discloses a hardware-assisted acceleration method and device for network flow, and the method comprises the following steps: collecting a network flow rule set supported by network card equipment when the network card equipment is accessed, and updating a network flow rule list; when a data packet is generated and a network flow is triggered, performing hierarchical matching on the network flow, the priority matching list, the priority processing list and the network flow rule list, and determining a first action which is not supported by the network card equipment and a second action which is supported by the network card equipment according to a matching result; executing the first action to complete the modification of the data packet, and reordering and combining the second action to generate a combined network flow; and unloading the modified data packet and the combined network flow to the network card equipment, so that the network card equipment executes the second action.
