Method and system for communication between user state and kernel

Abstract

The invention provides a method and system for communication of a user state and an inner core. The method for the communication of the user state and the inner core comprises the steps that a network data structure of a registered interface of a physical network card is obtained in the user state, the name of the registered interface of the physical network card is used for registering a virtual network card interface in the inner core according to the obtained network data structure of the registered interface of the physical network card, the physical network card in the user state is used for receiving mainframe receiving messages needing to be processed by the inner core, the mainframe receiving messages are transmitted to the inner core through a corresponding virtual network interface card, and the mainframe receiving messages processed by the inner core are transmitted to the user state through corresponding virtual network cards, and are sent to the physical network card through the user state. The method and system for the communication of the user state and the inner core can meet sensing requests of the physical network interface states by the user state and the inner core, and meanwhile the switchover problem of message formats of the user state and message formats of the inner core is solved. The system performance loss of information transmission between the user state and the inner core is reduced, the time of information transmission is saved, and efficiency of message transmission and processing is improved.

Description

technical field [0001] The invention relates to the field of data interaction, in particular to a method and system for communicating between a user state and a kernel. Background technique [0002] In the field of data interaction, the communication between user mode and kernel is a very important research topic. Due to the limitations of kernel mode programs, most kernel mode programs need to exchange and transmit data with user mode, so as to achieve wider expansion and application of the system. [0003] In the prior art, the following methods are mainly used to realize the purpose of communication between the user mode and the kernel: one method is to directly load the physical network card driver through the kernel, and send and receive messages at the external data terminal through the physical network card, and then send and receive messages through the data copy by the kernel. Business processing in the user state process; another method is to use the user state to...

Problems solved by technology

[0006] The present invention provides a method and system for communication between user state and kernel, which can perceive the physical state of the actual physical network interface and does not require message format conversion during the communication process, which solves the problem that there is no network interface in the prior art for physical perception question
