Problems solved by technology

[0004] The solution of running the network card driver and data processing applications in user mode will result in a particularly complex network card driver itself and complex interaction with the operating system.
When designing the interaction between the driver of the network card and the operating system, it is also necessary to consider the differences of the hardware platform, and configure the driver of the network card in a differentiated manner, so that the requirements for developers are particularly high, and the later maintenance of the driver of the network card is also more difficult. complex

Abstract

The present disclosure provides a data transmission method. The method includes: setting the driver program of the network card to run in the kernel state; setting the application program for data processing to run in the user state; mapping the network card to a mapped area in the memory through memory mapping; and mapping the mapped area based on the application program data processing based on the access of the driver; and data transfer based on the driver's access to the mapped area. The present disclosure also provides a data transmission device, system, medium and program product.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and more specifically, to a data transmission method, device, system, medium, and program product. Background technique [0002] When data transmission is performed through the network card, in related technologies, either the driver program of the network card and the application program for data processing are both run in user mode, or the driver program for the network card and the application program for data processing are both run in kernel mode. [0003] Among them, the solution of placing the driver program of the network card and the application program of data processing in the kernel state has high technical requirements for developers and needs to be familiar with the huge kernel source code. Moreover, the risk is high. Once the driver or data processing logic in the kernel mode crashes, the entire system will crash. In addition, the existing and more mature third-party us...
