Abstract: A data transfer method and a virtual switch, where when receiving a data packet, the virtual switch extracts characteristic information of the data packet, and determines, based on the extracted characteristic information of the data packet, whether an expedited forwarding rule is configured for a data stream to which the data packet belongs. If the expedited forwarding rule is configured for the data stream to which the data packet belongs, the virtual switch bypasses a LINUX bridge to directly send the data packet to a receive end, thereby reducing times of data packet switching between a kernel mode and a user mode, and improving data packet forwarding efficiency.
