Data processing method and device

Abstract

The present application provides a data processing method and device. In the method, one or more applications are run on the operating system of the first device. There are multiple paths between the first device and the second device. The multiple paths correspond to the One or more applications in the operating system of the first device, during the process of receiving data, the applications running in the operating system of the first device can obtain data on multiple paths with only one system call, and, for multiple paths, the data in multiple data packets can also be obtained from at least one path through this system call; in the process of sending data, one or more applications running in the operating system of the first device only pass through the system once The data of the one or more applications can be distributed to the corresponding path by invoking. It can be seen from this that during the process of receiving data or sending data, the number of system calls in this solution is small and the overhead is small, so the CPU utilization rate and power consumption of the first device can be reduced.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technologies, and in particular, to a data processing method and device. Background technique [0002] Computer applications often involve the interaction of information. An application usually runs in an operating system of a device such as a terminal or a server, for example, runs in a user state of the operating system. Therefore, the application needs to fall into the kernel state, read data from the kernel space corresponding to the kernel state or copy the data to be sent to the kernel space. . [0003] The application can be described by adopting the software system architecture architecture of client / server (Client / Server, C / S). Among them, the client and the server refer to the application in this architecture. Specifically, the application as the client (Client) requests services, and the application as the server (Server) provides services for the application as th...

Problems solved by technology

However, a system call will generate a lot of overhead, and an application frequently sends and receives data, an application uses multiple paths to send and receive data, and multiple applications run on a device are very common in actual application scenarios. Therefore, a In the process of exchanging data with other devices, the device is often occupied by frequent system calls, resulting in high CPU utilization and increased power consumption.
