Abstract

The invention discloses a data message processing method from a user mode to a kernel mode. The method comprises the steps that S1, a virtual network card is created in the kernel mode through a TUN/TAP driving manner; S2, a network card drive is loaded in the user mode, and network interface information in the user mode is sent to the virtual network card; S3, the virtual network card creates virtual interfaces according to the network interface information in the user mode, wherein the number and the state of the virtual interfaces are kept consistent with those of a network interface in the user mode; S4, when receiving a message needing to be processed by the kernel mode, the network interface in the user mode sends the message needing to be processed by the kernel mode to the virtual network card, and the virtual network card sends the message needing to be processed by the kernel mode to the kernel mode for processing. The method can be used for eliminating performance loss caused by loading a kernel network card drive and enabling the kernel mode to perceive the states of an actual physical network and a network interface.
