Data buffering method, data processing method, computer device, storage medium
A method including acquiring virtual location information of a virtual data buffer of a virtual network interface component; designating physical location information of a physical data buffer of a physical network interface component as the virtual location information; and storing data according to the virtual location information when the data is being stored into the physical data buffer.
