Computer transmission method

The invention relates to a computer transmission method. The computer transmission method includes setting a virtual computer mark for each virtual computer on a computer, assigning mapping identifications for mapping areas of the virtual computers, and setting a mapping space for a mapping area of the physical computer; setting limited sizes of transmitted data of the virtual computers; enabling one machine command to execute information within transmission capacity set by mapping marks of the assigned mapping areas of the virtual computers to a mapping identification of the mapping area of the physical computer. The computer transmission method has the advantages that the virtual computer marks are set for the virtual computers on the computer respectively, the mapping identifications are assigned for the mapping areas of the virtual computers, and the mapping space is set for the mapping area of the physical computer, so that the problem of high mapping table consumption in scanning of a current operating
