High-speed access method of files in network storage

Abstract

The invention provides a high-speed access method of files in network storage. The method has the basic ideas that firstly a metadata server for storing various metadata is set; after every time interval, the metadata collects the times that each file is accessed within the time interval, and a step of file selection is started; in the step, calculation on the welcoming degree and the tendency of the file is carried out by the file access frequency so that hot and outdated files can be selected out; afterwards, the most suitable server is searched through network communication yield calculation, a new copy of the hot file is copied, or a corresponding copy of the outdated file is deleted; next a copy of a harmful file is eliminated according to the reading and writing frequency of the file so that the file access speed is increased. Meanwhile, a data consistency mechanism of the invention enables the data to have the consistency by utilizing sequence number updating and ensuring condiitons of high delay and high packet loss rate. The method for improving the access speed of the files has wide research and application prospects under a network storage environment.

Description

technical field [0001] The invention proposes a high-speed file access method oriented to network storage, which belongs to the field of network storage. Background technique [0002] With the development of network technology, more and more IT companies provide users with large-scale storage systems through the Internet or private networks to meet the exponentially growing demand for storage space of enterprises or individual users. Therefore, how to make full use of network bandwidth resources, efficiently organize and manage users' files, and enable users to quickly access their required files has become a topic of most concern. At present, a relatively mature method is to redundantly copy files to multiple servers or caches, and distribute user access requests to reduce the load on the source file server and improve file access speed. However, most of the methods currently used are relatively rigid, and there is no good mechanism to intelligently manage different files...

AI Technical Summary

Problems solved by technology

[0003]1) Treat hot files and outdated files uniformly, waste too many network resources on outdated files, and make the overall file access efficiency low

[0004]2) There is no relevant mechanism to find the optimal server, and it is impossible to maximize the use of network resources

[0005]3) There is no file elimination mechanism to eliminate file copies that affect file access speed
