Abstract: A packet processing method for a virtual switch is carried out in a virtual switch under the SDN architecture. The method presets a signature pre-computation table including plural destination addresses and signatures corresponding to the destination addresses. With the installation of the signature pre-computation table, the destination addresses fall into packets of the signature pre-computation table without requiring computing the signature of the packet. The method simply obtains the corresponding signature according to the destination address of the packet destination address, and thus saves the time required for processing a packet and improves the throughput of the virtual switch.
