Problems solved by technology

However, due to the use of the P2P mode instead of the C / S mode to complete the download operation, it is necessary to modify the source code of the existing application program and recompile and install it, which greatly increases the labor of the developer, and also brings great harm to the end user who uses the electronic device. Inconvenience, so the P2P model has not been widely used
[0006] With the continuous enrichment of mobile Internet content, especially multimedia applications have gradually become the mainstream, it is obvious that while improving the user's audio-visual experience, it also consumes a large amount of network bandwidth and traffic

Abstract

The invention discloses a data access method and a data access device. The method is applied to electronic equipment, which has a multi-layer space architecture, and the multi-layer space architecture at least includes a user space layer and a kernel layer. The method includes: in the kernel layer, intercepting a request for accessing data issued from an application in the user space layer, and transmitting the request to a first file system; through the first file The system transmits the request to the determination unit in the user space layer; and determines the acquisition method of the data pointed by the request through the determination unit. Therefore, in the present invention, the method for obtaining data can be adaptively determined without modifying the application source code, thereby improving the user's data access experience.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically, the present invention relates to a data access method and a data access device. Background technique [0002] With the continuous development of computer technology, individual users have more and more high-performance electronic devices, such as smart phones, tablet computers (PAD), ultrabooks, smart TVs (Smart TV) and personal computers (PC). These feature-rich electronic devices not only have very strong computing power, but also have increasingly large storage space and fast Internet access capabilities. [0003] Today, with the rapid development of the Internet, file downloads of electronic devices are still mostly carried out in the client / server (Client / Server, C / S) mode. However, the file download service constructed in this mode is easily limited by the server side. [0004] For example, when many users download files from the server at the same time, th...
